Three dihydroanthracenones from Gasteria bicolor.

E Dagne1, B E Van Wyk, M Mueller, W Steglich.   

Abstract

The stem and leaves of Gasteria bicolor afforded three new dihydroanthracenones namely 3,4-dihydro-2,6,9-trihydroxy-8-methyl-1(2H)-anthracenone (gasteriacenone A), 3,4-dihydro-2,4,9-trihydroxy-6-methoxy-8-methyl-1(2H)-anthracenone (gasteriacenone B) and 3,4-dihydro-4,6,9-trihydroxy-7-carbomethoxy-8-methyl-1(2H)-anthraceno ne (gasteriacenone C). Their structures were determined by spectroscopic methods including 2D NMR techniques.
