Abstract
Amberin (1), a new sesquiterpene lactone, has been isolated from the ethyl acetate soluble fraction of Amberboa ramosa together with apigenin (2), jaseocidine (3), crysoeriol (4), and 3β, 8α-dihydroxy-11α-methyl-1αH, 5αH, 6βH, 7αH, 11βH-guai-10(14), 4 (15)-dien-6, 12-olide (5). The structures of the isolated compounds have been elucidated by 1D and 2D NMR spectroscopy.Entities:
