Chemical examination of the methanolic extract of the roots of Cassia pudibunda led to isolation of the new rubrofusarin-6-O-β-d-glucopyranoside, quinquangulin-6-O-β-d-apiofuranosyl-(1→6)-O-β-d-glucopyra noside, quinquangulin-6-O-β-d-glucopyranoside and chrysophanol dimethyl ether. Moreover the known chrysophanol, physcion, cis-3,3′,5,5′-tetrahydroxy-4-methoxystilbene, trans-3,3′,5,5′-tetrahydroxy-4-methoxystilbene, and cassiaside B were identified.

Abstract
Chemical examination of the methanolic extract of the roots of Cassia pudibunda led to isolation of the new rubrofusarin-6-O-β-d-glucopyranoside, quinquangulin-6-O-β-d-apiofuranosyl-(1→6)-O-β-d-glucopyra noside, quinquangulin-6-O-β-d-glucopyranoside and chrysophanol dimethyl ether. Moreover the known chrysophanol, physcion, cis-3,3′,5,5′-tetrahydroxy-4-methoxystilbene, trans-3,3′,5,5′-tetrahydroxy-4-methoxystilbene, and cassiaside B were identified. The antimicrobial activity of some of these compounds is also reported
