Full Text Available Background and objectives: The genus Colchicum belongs to the family Colchicaceae, which comprises of 19 genera, and 225 species worldwide. They have been recognized for more than 2000 years for their noticeable biological properties. The Colchicum species are well known for presence of tropolonic alkaloids, mainly colchicine. Colchicine, is still the drug of choice for treatment of gout, and is used for the treatment of a number of proinflammatory disorders, such as familial Mediterranean fever, and Behcet’s disease. Clinical studies have proved colchicine to posses potent anti-tumor activity. Colchicum speciosum Steven is an indigenous perennial herbaceous plant widely distributed in northern, central and western regions of Iran. Methods: In the present study, the phytochemical composition of MeOH extract from bulbs of C. speciosum collected fromSavadkouh region, Iranwas investigated by combination of HPLC-PDA-MS spectrometry and NMR specroscopy. The fractionation of MeOH extract was carried out by partitioning on CH2Cl2, EtOAc and water. Results: The isolation and purification of CH2Cl2 portion by combination of reverse and normal phase chromatography resulted in the isolation, purification and identification of two new tropolonic alkaloids, compounds (1 and (2, as well as two known compound colchicine (3 and demecolcine (4. Their structures were established by extensive spectroscopic methods, including 1D (1H NMR and 2D-NMR (COSY, HSQC and HMBC. The absolute configurations of isolated compounds were established by aid of circular dichroism. Conclusion: Phytochemical investigation of CH2Cl2 extract of C. speciosum by combination of HPLC, column chromatography and hyphenated spectroscopic techniques led to identification two new alkaloids with potential as lead compounds.

The plants of the Colchicum family were known during the archaic period in Greece for their deleterious properties. Later on, they were used for the treatment of podagra. The treatment was introduced by the ancient Greek physicians and passed on to the Byzantine and Arabian physicians to endure until nowadays. The first plant was most probably named "Medea" from the notorious Colchican witch. As the most common member of the family blossoms in autumn, the plant was named Colchicum autumnale. Various nominations were also used, such as Ephemeron, Hermodactyl, Anima articulorum and Surugen. Our article discusses them, while at the same time presents the most notable authorities who have used Colchicum plants in herbal medicine and toxicology.

The main objective of current study is to elucidate taxonomic, pharmacognostic and physicochemical behavior of Colchicum luteum (Suranjantalkh) for its proper identification and authentication from its cheap and tasteless adulterant. Colchicum luteum is one of the most rare and hence expensive medicinal plants. It is an active part of many unani formulations due to presence of an alkaloid colchicine which is claimed to be effective in arthritis, gout, rheumatism and internal injuries. In order to overcome demand of its corm, suppliers and herb sellers adultered bulbs of a monocotyledon plant Narcissus tazetta. This type of study reveals to be helpful in differentiating plants on basis of leaf epidermal anatomy, palynology, phamacognosy and physicochemical values. It is an important step in field of herbal medicine to provide pure and original medicinal plants to yield their maximum effectiveness. (author)
Full Text Available Colchicum autumnale (Colchicaceae is a perennial geophyte and a medicinal plant. Its biomass is collected for industrial uses for obtaining the alkaloids colchicine and demecolcine. The objective of the present study was to estimate the distribution and potential resources of C. autumnale populations in Bulgaria in terms of their sustainable use. Monitoring of habitats was carried out in concrete harvesting areas. The distribution of the populations and the amount of drug production in specific sites and conditions were studied. In 2014-2015, eleven localities were established in seven floristic regions, spread on an area of 498000 m². Seed resources obtained from the different populations ranged from 3.57 g to 12225 g. The seed yield depends on the environmental conditions, the number of plants per m², the number of fruit capsules per plant and the weight of the seeds contained in them. Changes in the management approach to habitats occupied by C. autumnale caused degradation of the areas, resulting in the decrease of the population density of the species.

Full Text Available In this research an ultrasound-assisted extraction (UAE method was used for extraction of colchicine in root of Colchicum haussknechtii prior to high-performance liquid chromatography with UV detection. C. haussknechtii is used widely in traditional medicine for the treatment of various diseases. The root of this plant is full of colchicine that is suitable for the treatment of gout and cirrhosis and applicable in plant breeding studies to produce polyploidy. The influence of variables on the extraction method was investigated by response surface methodology (RSM and composite design (CCD to achieve maximum extraction yield of colchicine from the root of C. haussknechtii. The most suitable condition for the extraction of colchicine was found to at 40 °C temperature, 32 min extraction time, and 70:30 v/v ethanol–water mixtures with 45:1 solvent-solid ratio. Obtained results showed that there is 1.2% colchicine in the root of C. haussknechtii, so this plant could be introduced as a rich source of colchicine.

We describe a case of a 43-yr-old female with severe multiorgan injury after accidental poisoning with Colchicum autumnale, which was mistaken for wild garlic (Allium ursinum). Both plants grow on damp meadows and can be confused in the spring when both plants have leaves but no blossoms. The autumn crocus contains colchicine, which inhibits cellular division. Treatment consisted of supportive care, antibiotic therapy, and granulocyte-directed growth factor. The patient was discharged from the hospital after three weeks. Three years after recovery from the acute poisoning, the patient continued to complain of muscle weakness and intermittent episodes of hair loss.
Full Text Available This paper covers the screening of the secondary plant products to find a cure against cancer which were piled up during the years. In early stages of these studies highly active antitumor glycoproteins were obtained from native Arizona (USA plants. Later smaller molecules were isolated showing antitumor activity in different test systems. Among these compounds sesquiterpene lactones with an exo-methylene group in the lactone ring, unsaturated diterpenoids and some triterpenoids exhibited activity in vivo and in vitro test systems. A few Colchicum alkaloids showed high activity against murine lymphocytic leukemia (P388. Activity also established in some flavonoidal compounds. Today all around the world research on Natural Products is still going on.
Full Text Available Alkaloids, nitrogen-containing secondary plant metabolites, are of major interest to veterinary toxicology because of their occurrence in plant species commonly involved in animal poisoning. Based on epidemiological data, the poisoning of cattle and horses by alkaloid-containing plants is a relatively common occurrence in Europe. Poisoning may occur when the plants contaminate hay or silage or when forage alternatives are unavailable. Cattle and horses are particularly at risk of poisoning by Colchicum autumnale (meadow saffron, Conium maculatum (poison hemlock, Datura stramonium (jimson weed, Equisetum palustre (marsh horsetail, Senecio spp. (ragwort and groundsel and Taxus baccata (European yew. This review of poisonous alkaloid-containing plants describes the distribution of these plants, conditions under which poisoning occurs, active toxic principles involved and subsequent clinical signs observed.
In Turkey, the majority of the population live in rural areas where they use wild plants as food and medicine. The confusion of an edible plant with a poisonous one give rise to serious poisoning which may even result in death. The incidence of plant poisoning in Turkey is about 6% and especially high among children between ages of 2 and 11 living in rural areas. The number of species that cause poisoning is around twenty and Hyoscyamus niger (Solanaceae), Colchicum species (Liliaceae), Conium maculatum (Umbelliferae) and Prunus species (Rosaceae) are the most important. Mushroom poisoning is more frequent in spring and fall. The main reasons are their widespread usage as food and the inexperience of the gatherers in distinguishing the edibles from the poisonous. Amanita phalloides, A. verna, A. muscaria, A. pantherina are responsible for severe cases of poisoning.

Full Text Available Bilateral acute iris transillumination (BAIT is a recently defined disease characterized with bilateral acute, severe pigment dispersion of iris and pupil sphincter paralysis. The etiopathogenesis of the disease is unknown, but antibiotics such as moxifloxacin, clarithromycin, viral infections, and fumigation therapies were considered as probable etiologic factors. A 33-year-old female was referred to our clinic for acute iridocyclitis refractory to azathioprine, colchicum and corticosteroid treatments. Ophthalmic examination revealed bilateral pigment dispersion, significant iris transillumination, heavy pigment deposition in iridocorneal angle, and elevated intraocular pressure. Upon systemic evaluation she was found to have bacterial urinary tract infection. BAIT is an important cause of pigment dispersion and clinicians must be vigilant for this condition to avoid unnecessary diagnostic tests and treatment.
Full Text Available Background. A case of accidental poisoning with autumn crocus (Colchicum autumnale that was misinterpreted for wild garlic (Allium ursinum is presented. Both plants grow on damp meadows and can be easily wrongly identified especially before blooming period as they have similar, pointed leaves.Results. Considering anamnestic data, clinical picture and laboratory findings in 43-yr-old female, a poisoning with the colchicine plant alkaloid was suspected. Later, it was confirmed by toxicology analyses (chromatography and spectrometry of the collected serum and urine samples. Severe initial gastrointestinal disorders progressed into ileus, bone-marrow suppression and multi-organ failure.Conclusions. After the patient had received a symptomatic treatment with granulocyte-directed growth factor and a suitable antibiotic therapy for secondary infection, she recovered within three weeks from the onset of condition. The most persistent problem was alopecia. The disease did not entailed any permanent sequellae which was confirmed 3 years after the patient was considered cured.

Ingestions of Colchicum autumnale may lead to severe poisoning. It begins with gastrointestinal symptoms and leukocytosis, followed by multi-organ failure with shock and a possible late recovery phase. Mortality is highly dependent on the ingested dose. We report a case of accidental C. autumnale poisoning with refractory cardiogenic shock and eventual survival after extracorporeal life support (ECLS). A 68-year-old woman was admitted to the intensive care unit (ICU) on day 3 after ingestion of C. autumnale in a meal. She first suffered from nausea and vomiting leading to severe dehydration. She then developed multi-organ failure and refractory cardiogenic shock, with a mean arterial pressure nadir of 50 mmHg despite high doses of catecholamines and a left ventricular ejection fraction at 5-10%. Venous-arterial ECLS was therefore started at an initial rate of 3.5 L/min and 3,800 rev/min. Her symptoms also included pancytopenia on day 4 with diffuse bleeding requiring iterative blood product transfusion. Platelet and leukocyte count nadirs were 13 × 10(9)/L (normal range: 150-400 × 10(9)/L) and 0.77 × 10(9)/L (normal range: 4.2-10.7 × 10(9)/L), respectively. ECLS allowed good cardiac contractility recovery within a few days, with complications including bleeding made controllable. Indeed, because of hemostasis disorders, the patient presented hemoptysis and hematuria. She was treated with tranexamic acid and transfused with blood products. She received 15 erythrocyte concentrates, 13 platelet concentrates, and 7 fresh frozen plasma. ECLS was removed by day 10, with subsequent weaning from mechanical ventilation as well as from hemodialysis in the following days. This patient survives after the use of ECLS in Colchicum poisoning, with controllable complications. Thus, ECLS might be indicated to overcome the potentially refractory cardiogenic shock phase.

Many environmental problems like dam construction, agricultural debris, flooding and industrial establishments threaten Iyidere stream (Rize, Turkey) on the southeastern coast of the Black Sea (Turkey). The trace element concentrations in water, fish and sediments in lyidere stream (Rize, Turkey) were investigated in this study. The concentration of six different elements in ten freshwater fish species and sediment was determined using energy dispersive X-ray fluorescence method. A radioisotope excited X-ray fluorescence analysis using the method of multiple standard addition is applied for the elemental analysis of fish and sediments. Water samples for trace metals were analyzed using standard spectrophotometry methods. A qualitative analysis of spectral peaks showed that ten different freshwater fish samples (Chondrostoma colchicum, Chalcalburnus chalcoides, Salmo trutta labrax, Alburnoides bipunctatus, Leuciscus cephalus, Barbus taurus escherichia, Capoeta tinca, Neogobius kessleri, Rutilus frisii, Lampetra lanceolata) and sediment contained phosphorus (P), sulphur (S), chlorine (Cl), potassium (K), calcium (Ca) and titanium (Ti). Heavy metals as toxic elements for biota (Pb, Cd, Hg, Zn and Mn etc.) were not detected in fish, water and sediments. Thus, It can be declared that freshwater fish of Iyidere does not contains health risks for consumers in terms of metal pollution.

Full Text Available Colchicine, extracted from the colchicum autumnale plant, used by the ancient Greeks more than 20 centuries ago, is one of the most ancient drugs still prescribed even today. The major mechanism of action is binding to microtubules thereby interfering with mitosis and subsequent modulation of polymorphonuclear leukocyte function. Colchicine has long been of interest in the treatment of cardiovascular disease; however, its efficacy and safety profile for specific conditions have been variably established in the literature. In the subset of pericardial diseases, colchicine has been shown to be effective in recurrent pericarditis and post-pericardiotomy syndrome (PPS. The future course of treatment and management will therefore highly depend on the results of the ongoing large randomized placebo-controlled clinical trial to evaluate the efficacy and safety of colchicine for the primary prevention of several postoperative complications and in the perioperative period. Also, given the positive preliminary outcomes of colchicine usage in pericardial effusions, the future therapeutical use of colchicine looks promising. Further study is needed to clarify its role in these disease states, as well as explore other its role in other cardiovascular conditions.
Full Text Available Our study documents information on rarity, geographical distribution, taxonomy and conservation status of 11 geophyte species in serpentine soils of Kosovo, already included in the Red Book of Vascular Flora of Kosovo. Kosovo’s serpentine vegetation represents a diversity that yet has not been sufficiently explored. Large serpentine complexes are found in the northern Kosovo but also southern part of the country is rich in serpentines, therefore in endemics. Serpentine rocks and soils are characterized by low level of principal plant nutrients (N, P, K, Ca and exceptionally high levels of Mg and Fe. Serpentines play particular importance for flora of the country due to their richness in endemic plant species. The following 11 plant species have been studied: Aristolochia merxmuelleri, Colchicum hungaricum, Crocus flavus, Crocus kosaninii, Epimedium alpinum, Gentiana punctata, Gladiolus illyricus, Lilium albanicum, Paeonia peregrina, Tulipa gesneriana and Tulipa kosovarica. Five out of eleven studied geophytes fall within Critically Endangered IUCN based threat category and five out of eleven are local endemics. Aristolochia merxmuelleri and Tulipa kosovarica are steno-endemic plant species that are found exclusively in serpentine soils. Information in our database should prove to be valuable to efforts in ecology, floristics, biosystematics, conservation and land management.

In this research paper efforts have been made to document the ethno-botanical knowledge of important plant species found in Northern Pakistan. It includes Thandiani, Galiat, Kaghan, Swat, Buner, Dir, Chitral and Northern Areas of Pakistan. The area has many climatic and vegetation zones or biomes. Locals residing in mountainous areas belonging to various ethnic groups are traditionally utilizing plants over many generations; these ethnic groups have their distinct life style, belief, traditions and cultural heritage. Plant collection and data regarding traditional uses in various areas of Northern Pakistan has been done periodically in different flowering /fruiting seasons. Locals of old age belonging to various ethnic groups were personally interviewed for establishing uses of plants. Photography is done for easy identification and habitat recognition. Collected plant specimens and seeds were preserved. Plant species were dried, mounted, identified and authenticated. Seventy six species were known to have traditional and ethno botanical uses. Plants have been utilized for many generations. Ethnic groups have distinct life style and have different economic uses for these plants. Due to unsustainable exploitation of natural habitats scarcity of drug plants has occurred. As consequence some species are depleting and may become extinct in near future, e. g. Morchella esculenta, Colchicum lueteum and Viola serpens are just a few of these. Although some sporadic information is available about the flora of this region but very little documented record of the ethno-botanically important plants has been established. It is expected that this research paper will be beneficial for students, researchers, farmers, foresters and general public. On the basis of data obtained it is concluded that ethno-botanical Flora of Northern Pakistan is quite rich and is diverse, due to the difference in altitude, climate and other topographic conditions.

First identified by the Egyptians in 2640 BC, podagra (acute gout occurring in the first metatarsophalangeal joint) was later recognized by Hippocrates in the fifth century BC, who referred to it as 'the unwalkable disease'. The term is derived from the Latin word gutta (or 'drop'), and referred to the prevailing medieval belief that an excess of one of the four 'humors' – which in equilibrium were thought to maintain health – would, under certain circumstances, 'drop' or flow into a joint, causing pain and inflammation. Throughout history, gout has been associated with rich foods and excessive alcohol consumption. Because it is clearly associated with a lifestyle that, at least in the past, could only be afforded by the affluent, gout has been referred to as the 'disease of kings'. Although there is evidence that colchicine, an alkaloid derived from the autumn crocus (Colchicum autumnale), was used as a powerful purgative in ancient Greece more than 2000 years ago, its first use as a selective and specific treatment for gout is attributed to the Byzantine Christian physician Alexander of Tralles in the sixth century AD. Uricosuric agents were first used at the end of the 19th century. In the modern era, nonsteroidal anti-inflammatory drugs are usually the drugs of choice for treating acute gout. Perhaps the most important historical advance in the treatment of hyperuricemia was the development of xanthine oxidase inhibitors, which are effective in reducing plasma and urinary urate levels and have been shown to reverse the development of tophaceous deposits.

Ingestions of plants rarely lead to life-threatening intoxications. Highly toxic plants, which can cause death, are monkshood (Aconitum sp.), yew (Taxus sp.) and autumn crocus (Colchicum autumnale). Lethal ingestions of monkshood and yew are usually suicides, intoxications with autumn crocus are mostly accidental ingestions of the leaves mistaken for wild garlic (Allium ursinum). Severe intoxications can occur with plants of the nightshade family like deadly nightshade (Atropa belladonna), angel's trumpet (Datura suaveolens) or jimsonweed (Datura stramonium). These plants are ingested for their psychoactive effects. Ingestion of plant material by children most often only causes minor symptoms or no symptoms at all, as children usually do not eat great quantities of the plants. They are especially attracted by the colorful berries. There are plants with mostly cardiovascular effects like monkshood, yew and Digitalis sp. Some of the most dangerous plants belong to this group. Plants of the nightshade family cause an anticholinergic syndrome. With golden chain (Laburnum anagyroides), castor bean (Ricinus communis) and raw beans (Phaseolus vulgaris) we see severe gastrointestinal effects. Autumn crocus contains a cell toxin, colchicine, which leads to multiorgan failure. Different plants are irritative or even caustic to the skin. Treatment is usually symptomatic. Activated charcoal is administered within one hour after ingestion (1 g/kg). Endoscopic removal of plant material can be considered with ingestions of great quantities of highly toxic plants. Administration of repeated doses of charcoal (1-2 g/h every 2-4 hours) may be effective in case of oleander poisoning. There exist only two antidotes: Anti-digoxin Fab fragments can be used with cardenolide glycoside-containing plants (Digitalis sp., Oleander). Physostigmine is the antidote for severe anticholinergic symptoms of the CNS. Antibodies against colchicine, having been developed in France, are not available at

Colchicine inhibits the deposition of uric acid crystals and is an inhibitor of mitosis. Nausea, vomiting, abdominal pain, and diarrhea, with a massive loss of fluid and electrolytes are the first clinical symptoms of colchicine poisoning. Stomach lavage and rapid gastric decontamination with activated charcoal are crucial. An acute dose of about 0.8 mg/kg of colchicine is presumed to be fatal. We report the clinical outcomes of two different cases of colchicine intoxication for attempted suicide. The dose required for morbidity or mortality varies significantly. The dose of 1 mg/kg in the first case was directly related with mortality, while the dose of 0.2 mg/kg in the second was related with survival. The other difference between the patients was the time of arrival to hospital after ingestion. This period was 4 hours for case 1 and only 1, hour for case 2. The initiation of treatment later than 2 hours after ingestion of colchicine may significantly impair treatment because the absorption time for colchicine after oral administration is about 30–120 minutes. The rising lactate level and high anion gap metabolic acidosis in our patient (case 1 were attributed to lactic acidosis, so hemodialysis was performed, and the duration of hemodialysis was prolonged. Lactic acidosis in the first case was one of the reasons for mortality. The most important parameters which define the chance of survival are the dose of ingested drugs and the arrival time to hospital after ingestion. The patients must be monitored closely for lactic acidosis
