rutaevin/dictamnus

Rutaevin was isolated from the root bark of Dictamnus dasycarpus. It has been obtained from genus Dictamnus for the first time.

OBJECTIVE To isolate and identify the chemical constituents from the root bark of Dictamnus dasycarpus. METHODS Silica gel, Sephadex LH-20, ODS and PTLC were employed for the isolation and purification of chemical constituents. The structures were identified on the basis of spectral data and

A methanolic extract of Dictamnus dasycarpus root bark afforded four new degraded limonoids, 9alpha-hydroxyfraxinellone-9- O-beta- d-glucoside ( 1), dictamnusine ( 2), dictamdiol A ( 3), and dictamdiol B ( 4), together with eight known compounds, dictamdiol ( 5), fraxinellone ( 6), fraxinellonone (
