Papaya (Carica papaya L.) is well known for the its exceptional nutritional and medicinal properties throughout world. From past, whole plant including leaves, seeds, ripe unripe fruits their juice used as a traditional medicine. The fruit has large oval shape, yellowish – green yellow flesh. Phytochemically it contains enzymes papain, chymopapin, which biologically actives value. They also con...

A number of Plantago spp. especially P. major has long been used in the treatment of diseases such as infection, inflammation and cancer. In this study, we evaluated the immunomodulatory activities of five chemical classes of pure compounds obtained from the Plantago genus on human peripheral blood mononuclear cells (PBMC). Studies were conducted on lymphocyte transformation by BrdU immunoassay...

Conditions enabling the single-step preparative synthesis of chiral 4-fluoropolyhydro-2H-chromenes in good yields through a reaction between monoterpenoid alcohols with para-menthane skeleton and aldehydes were developed for the first time. The BF3·Et2O/H2O system is used both as a catalyst and as a fluorine source. The reaction can involve aliphatic aldehydes as well as aromatic aldehydes cont...

Biosynthesis of (1R,4aS,7S,7aR)-nepetalactol (1) and (4aS,7S,7aR)-nepetalactone (2) in plants involves iridoid synthase (ISY), an atypical reductive cyclase that catalyses the reduction 8-oxogeranial into reactive enol (S)-8-oxocitronellal, cyclization this intermediate, either non-enzymatically or by a nepetalactol-related short chain dehydrogenase enzyme (NEPS) yields nepetalactols. In study,...

callus and suspension cultures of lavandula angustifolia mill. (lamiaceae) were established and the effect of different culture media on growth rate was investigated. terpenoids added to suspension culture to investigate their biotrans-formation. all samples were analyzed by gas chromatography (gc) and gc-mass spectroscopy (ms). octan-1-ol, citronellol, linalool, borneol and geraniol were biotr...
