Abstract:
Two new fatty acid glucosides, (3E,8Z)-8-carboxy-1-(O-beta-D-glucopyranosyl)-2,6-dihydroxytritriaconta-3,8-diene (1) and (8Z)-8-carboxy-1-(O-beta-D-glucopyranosyl)-3,4-epoxy-2,6-dihydroxytritriacont-8-ene (2), have been isolated from the root bark of Ochna calodendron and their structures elucidated by extensive two-dimensional NMR methods including HMQC, HMBC and NOESY experiments.
