Aureanin: a new iridoid from the leaves of (Silva Manso) Benth. & Hook.f. ex S.Moore.

One new iridoid named aureanin () was isolated from the leaves of (Silva Manso) Benth. & Hook.f.

Cytotoxic and antileishmanial triterpenes of (Silva Manso) leaves.

The bioactivity-guided fractionation of the total ethanolic extract of the leaves of revealed the cytotoxic and antileishmanial potency of the ethyl acetate fraction, in which its phytochemical investigation resulted in the isolation of five triterpenes; identified as oleanolic acid (), ursolic acid (), pomolic acid (), tormentic acid (), 3,6,19-trihydroxy-urs-12-en-28-oic acid () in addition to one triterpenoid glucoside, spathodic acid 28---D-glucopyranoside (). Whereas compound showed cytotoxic activity against three different cell lines; A549, MCF-7 and HepG2 with IC values of 31.7 ± 1.
