A CRITICAL PHYTOCHEMICAL ANALYSIS OF DIFFERENT SOURCES OF SARIVA FROM ITS NATURAL HABITAT

The material medica has over 25000 plant species having therapeutic value, and more than 500 are used in indigenous systems of medicine. Sariva is one such drug having multifaceted activities widely used as coolant, blood purifier. In Ayurvedic classics two varieties have been mentioned, Shweta and Krishna. Regarding the botanical identity of both the varieties, Shweta Sariva is unanimously accepted as Hemidesmus indicus, where as for Krishna Sariva is accepted as both Ichnocarpus frutescens, Cryptolepis buchnani. In the market, by the name of Sariva Decalepis hamiltonii is usually sold. Hence all the four sources were collected from their natural habitat, subjected for phytochemical analysis, including its morphological features and HPTLC was carried out. In this research work it was found that the four sources of Sariva have match with standards mentioned in quality standards of Indian medicinal plants, published by ICMR, New Delhi. Further these sources should be subjected for pharmacological evaluations pertaining Sariva as to confirm the genuine source and best substitute.

Biological attributes and qualitative damage of Oligonychus mangiferus (Rahman & Sapra) (Acariformes: Tetranychidae) on the medicinal plant Ichnocarpus frutescens (L.) W.T. Aiton

Oligonychus mangiferus (Rahman & Sapra) was found infesting the medicinal plant, Ichnocarpus frutescens L. Its biology and reproduction were studied at four different constant temperature conditions in the laboratory. O. mangiferus completed its development faster (7.10 to 8.77 days) at 30° - 32°C. Its egg-laying was highest at 20°C (31.03 eggs/female), but with similar progenial sex ratio ( :? ) (1:2.68 to 1:2.84) across different temperatures. At 25°C, Mean Generation Time (T) and Doubling Time (DT) were lowest 15.26 days and 8.95 days, respectively, while, Intrinsic Rate of Natural Increase (rm) was highest (0.085 female off-springs/female/day). Feeding damage by mangiferus resulted in apparent decline in chlorophyll and flavonoid contents, while alkaloid and terpenoid contents showed increase in mite infested leaves. Observed changes in the quantity of secondary metabolites like alkaloids, flavonoids and terpenoids, subsequent to mite feeding was significant, owing to the medicinal value of the herb. Further investigation on these biochemical changes may throw light on more advantageous medicinal use of Ichnocarpus for treating many human disorders.
