摘要:Abstract Different fractions of root and stem of Derris scandens demonstrated good antibacterial (Escherichia coli, and Bacillus megaterium), antialgal (Chlorella fusca), and antifungal (Microbotryum violaceum) activities. Phytochemical investigation resulted in isolation of scandenin, scandenin A, betulinic acid, lupeol, β-amyran-3-one, β-amyrin, β-sitosterol and ß-sitosterol glucopyranoside. Study showed that scandenin has strong antibacterial activity against B. megaterium and good antifungal and antialgal properties. Scandenin A showed good antibacterial, antifungal and antialgal properties.
