Hexane, chloroform and methanol extracts of the rootwood and rootbarks of Jatropha podagrica were studied for their antimicrobial activity against 18 organisms. All the extracts exhibited some broad spectrum antibacterial activity, at a concentration of 20 mg/mL. The hexane extracts were generally m
From the EtOAc extract of the latex of Jatropha pohliana (Euphorbiaceae), two cyclic heptapeptides, pohlianins A (I) and B (2) and one cyclic octapeptide, pohlianin C (3) were isolated by a multi-step chromatography procedure,, including HPLC. Their structure were elucidated by chemical degradation,
