“…Coumarinolignoids were isolated from the plant as naturally occurring compounds with cytotoxic and hepatotoxic properties 14 . Other phytochemicals such as terpenoids, β‐sitosterol, pregnane glycosides, pregnane ester glycoside, and indicusin were isolated from the root powder 15–20 . 2‐Hydro2‐Methoxybenzoate was isolated during root culture of the plant 21 .…”

Phytochemical Screening and Antibacterial Studies on Leaf and Root Extracts of Asclepias Curassavica (L).

“…The glycoside patterns of the saponin are often complex, may have as many as five sugar units attached and glucuronic acid is a common component. Saponin glycosides have been reported in the related member H. indicus [27]. Alkaloids and tannins are entirely lacking from leaf material, but less quantity of tannins were present in root material.…”
