Three different magnetic regimes; aerial, surface and buried; each with three different forces, have been used to investigate their effects on the water contents and photosynthetic pigments of sweet basil plants (Ocimum basilicum L.). Two groups of sweet basil seeds, Ocimum basilicum L. have been cultivated, one under normal conditions and the second has been subdivided into three portion (aerial, surface and buried) to examine the effect of different magnetic forces coming from the three directions on the resulted plants. At all directions of magnets, water contents have been significantly affected by the magnetic forces. Chlorophyll A and carotene contents have been affected, as well, according to the three magnetic forces coming from soil surface regime only. Chlorophyll B did not significantly affected by differences magnetic forces in the three regimes, but it is affected by magnetism wherever its direction or force. But all the ...

The levels of four different heavy metals [cadmium (Cd), lead (Pb), chromium (Cr) and copper (Cu)] were determined in various vegetables [leek (Allium ampeloprasum), sweet basil (Ocimum basilicum), parsley (Petroselium cripsum), gardem cress (lepidium sativum) and tarragon (Artemisia dracuncullus)] cultivated around the Sanandaj city.

Eremostachys laciniata (L) Bunge (family: Lamiaceae alt. Labiatae; subfamily: Lamioideae) is one of the 15 endemic Iranian herbs of the genus Eremostachys. A decoction of the roots and flowers of E. laciniata has traditionally been taken orally for the treatment of allergies, headache and liver diseases. Three antibacterial iridoid glucosides, phloyoside I (1), phlomiol (2) and pulchelloside I (3) have been isolated from the rhizomes of this plant. The structures of these compounds were elucidated unequivocally by a series of 1D and 2D NMR analyses. The antibacterial activity and brine shrimp toxicity of these compounds were assessed using the resazurin microtitre assay and the brine shrimp lethality assay, respectively. All three iridoid glycosides 1-3 exhibited from low to moderate level...

A field experiment was conducted during 2004 and 2005 at the research farm of Central Institute of Medicinal And Aromatic Plants, Lucknow located at 26.5^o N 80.5^o E and 120m above the mean sea level to study the effect of harvesting stage and cutting height on growth, yield and quality of Indian basil. The objective of this study was to increase the essential oil yield of Indian basil without adverse effect on quality by taking two harvests through manipulating harvesting stage and cutting height and to increase the land and rain water utilization efficiency under rain fed condition. The treatments consisted of four stages of first harvest (40, 60, 80 and 100 days after transplanting (DAT)) and three cutting height (0, 7.5 and 15.0cm above ground level). The Indian basil (Ocimum basilicu...

A red basil cell line (T2b) rich in rosmarinic acid (RA) was selected for the stable production of anthocyanins (ACs) in the dark. Cell suspension cultures were subjected to mechanical stress through increased agitation (switch from 90 to 150rpm) to determine the relationship between AC and RA accumulation. Cell extracts were analyzed by HPLC and LC-MS, and the resulting data were processed with multivariate statistical analysis. MS and MS/MS spectra facilitated the putative annotation of several complex cyanidin-based ACs, which were esterified with coumaric acid and, in some cases, also with malonic acid. It was also possible to identify various RA-related molecules, some caffeic and coumaric acid derivatives and some flavanones. Mechanical stress increased the total AC and RA contents, ...

Full text: The excessive use of chemical pesticides to control agricultural pests is becoming alarming. The objective of this study is to search for biopesticides of plant origin that could be used to control one of the major pest of fruit production; the Mediterranean fruit fly (Ceratitis capitata Wied.). A colony of the Lebanese wild strain of this insect was reared under laboratory condition to provide biological material. The insecticidal activity of the essential oils extracted from aromatic plants in Lebanon was assessed. The tested plants are: Foeniculum vulgare, Thymbra spicata, Artemisia herba alba, Origanum syriacum, Ruta chalepensis, Lavandula stoechas, Salvia fruticosa, Mentha microphylla, Juniperus oxycedrus, Rosmarinus officinalis, Myrtus communis, Laurus nobilis and Ocimum gratissimum. Results show that essential oils isolated from F. vulgare, T. spicata, A. herba alba, O. syriacum and R. chalepensis have promising insecticidal potential. (author)

The present study investigated the effects of peppermint (Mentha piperita), dill (Anethum graveolens) and basil (Ocimum basilicum) on yogurt formation, proteolysis and inhibition of angiotensin-1 converting enzyme (ACE). Herbal-yogurts had faster rates of pH reduction than plain-yogurt. All herbal-yogurts had higher (p < 0.05) antioxidant activities than plain-yogurt, both at the end of fermentation and throughout the storage period. The o-phthalaldehyde (OPA) peptides in herbal-yogurts increased by 28-36% after 7 days of storage. All herbal-yogurts showed higher anti-ACE activity than plain-yogurt at corresponding storage periods. M. piperita yogurt had highest inhibitory effect on ACE activity throughout the storage period. Peppermint, dill and basil may be used to modify microbial ferme...
