Combretene-A and B:: Two new triterpenes from Combretum molle

Two new lanosteriod type triterpenes have been isolated from the aerial parts of Combretum molle. Their structures have been established on the basis of spectral data as 3beta,7alpha-dihydroxy lanost-5-ene, designated as combretene-A (1), and 3beta-hydroxy-28-hydroxymethyl lanost-25(26)-ene, named as combretene-B (2). Previously reported compounds, such as a 1alpha-hydroxy cycloartenoid (mollic acid), and its 3alpha-L-arabinoside, 3beta-D-Xyloside and 3beta-D-glucoside, have also been isolated from the plant.
