RESUMO
Six compounds were isolated from Monsonia nivea Decne. Webb. [Geraniaceae] growing in Egypt. The compounds are sterol, triterpene and flavonoid in nature. These compounds were identified as alpha-amyrin, beta-sitosterol, ursolic acid, apigenin-7-O-beta-D-glucopyranoside, quercetin-3-O-glucoside and rutin. The structures of the isolated compounds were confirmed by different spectroscopic methods. The anti-oxidant, anti-bacterial and the DNA-binding activities [as an indicator for anti-tumor activity] were carried out for the extracts and some pure compounds
