also showed antifungal activity against ringworm causing fungi. Flower extract inhibits fungal growth.EtOH extract of roots showed invivo activity against P-388 leukaemia in mouse and in vitro against human carcinoma cells of nasopharynx (KB).The root contains antileukaemic iridoid lactone, allamandin and two other iridoids, allamandicin and allamdin.The stems and leaves contain betaamyrin,beta-sitosterol and ursolic
