Twenty new pregnane glycosides were obtained from the roots of Asclepias syriaca L. (Asclepiadaceae). These glycosides were confirmed to contain ikemagenin, 12-O-nicotinoyllineolon, 5alpha,6-dihydroikemagenin, and 12-O-tigloylisolineolon, as their aglycones, using both spectroscopic and chemical methods.

Secondary plant metabolites and their derivatives play a significant role in human health. Ferruginol is diterpene phenol that has recently received attention for its pharmacological properties, including antibacterial, antitumor, antimalarial, cardioprotective effects. Recently, we detected the ferruginol compound leaf seed extracts of Juniperus procera using different analytical approaches. T...

In the present investigation various bioassays were conducted to evaluate the anti-termite efficacy of plant latex based formulations to control population of Indian white termite in subtropical soil. Results reveal that crude latex, its fractions and combinatorial fractions have shown very high toxicity against O. obesus. The LD50 values for different latex fractions of 24 h were in a range of...
