Theory predicts patterns of defense across taxa based on notions of tradeoffs and synergism among defensive traits when plants and herbivores coevolve. Because the expression of characters changes ontogenetically, the evolution of plant strategies may be best understood by considering multiple traits along a trajectory of plant development. Here we addressed the ontogenetic expression of chemic...

Three adult patients, two of whom were brothers and the third their uncle, were brought to my dispensary. They said that they had taken together some home-made sattu (flour of fried wheat and gram made into paste with sugar) in the morning, and since then were feeling very dizzy. They had come to the dispensary within one hour after their breakfast of sattu. Although no foul play was suspected,...

Two stereoisomeric cardenolides, uscharin (1) and a new compound, 2'-epi-uscharin (2), were isolated from the latex of Calotropis gigantea (Asclepiadaceae). Their structures were fully elucidated based on their spectroscopic data, X-ray crystallographic data and chemical evidences. Both epimers (1 and 2) exhibited strong inhibitory effects on HIF-1 activity with different magnitudes. Compound 1...

The kinetic of atropine pertraction from seeds of Datura Metel Linn plant was studied. Diisopropyl ether, n-hexane and n-heptane were used as membranes for atropine recovery. The effect of speed of agitation and time in the range of 200-300 rpm and 0-3.5h, respectively were studied using the proposed membranes. The pertraction experiments were carried outs in a batch laboratory unit. The liquid...

We provide the scientific basis for the use of Calotropis procera for treating skin and wound infections in traditional medicine. The aqueous extract of stem-bark of C. procera exhibited more pronounced potent antimicrobial activity. Calo-protein was purified and identified from the most-active aqueous extracts of C. procera and showed broad-spectrum activity. Calo-protein inhibited the growth ...
