The plant has anthelmintic, laxative, antidiabetic, hepatoprotective and anti-inflammatory activities. The pharmacological properties of this plant come from bioactive phytochemicals such as alkaloids, triterpenes, saponins and flavonoids. Phytochemically, the plant has been investigated for the presence of cardenolides, alkaloids, saponins and steroidal compoundst. In the present study, we developed a rapid method for identification and quantitative determination of putative phyto compounds in the crude extracts of ethyl acetate and methanol from whole plant of Pergularia daemia.展开更多
