Constituents from Moghat, the roots of Glossostemon bruguieri (Desf.)

The new biflavone moghatin (3'-hydroxycupressuflavone) was isolated from Moghat, the dried peeled roots of Glossostemon bruguieri (Desf.), together with five known compounds: 4'-methoxyisoscutellargin, sesamin, chrysophanol, emodin and methoxyemodin (physcion). The structures of these compounds were assigned on the basis of spectroscopic data. Occurrence of these compounds in Moghat is reported here for the first time.
