Abstract

A new ent-abietane lactone, 3-oxojolkinolide A (1), together with 16 known compounds, helioscopinolide E (2), helioscopinolide A (3), 3-methyl-9H-carbazole (4), carbalexin (5), carbalexin B (6), glycaborinine (7), arborinine (8), 1H-indole-3-carbaldehyde (9), glycoamide A (10), glycoamide B (11), 2-(N-methyl-2-phenylacetamido)benzoic acid (12), 2-(methylamine)-methylbenzoate (13), fraxidin (14), scopoletin (15), (-)-syringaresinol (16) and ferulic acid (17) were isolated from Glycosmis pentaphylla. The structures of these compounds were elucidated using spectroscopic techniques such as NMR and MS. Among them, compounds 13, 9 and 12-17 were isolated from the genus Glycosmis for the first time.
