Abstract
To study the active principles in root core of Tripterygium wilfordii Hook. f., eleven diterpenoid compounds were isolated from this plant by silica gel column chromatography. Their structures were identified as triptoquinone A (1), hypoglic acid (2), triptoquine (3), isoneotriptophenolide (4), hypolide (5), triptonoterpene methyl ether (6), triptriolide (7), triptonide (8), triptolide (9), tripterfordin (10), 11-O- β-D -glucopyranosylneotritophenolide (11). Compound 11 is a novel compound.
