摘要
From the dried roots of Cephaelis acuminata, five tetrahydroisoquinoline-monoterpene glycosides, 2-O-beta-D-glucopyranosyldemethylalangiside, demethylisoalangiside, 6"-O-beta-D-glucopyranosylipecoside, 6"-O-alpha-D-glucopyranosylipecoside and (4R)4-hydroxyipecoside, were isolated. The structures of these glycosides were determined by spectroscopic and chemical means. (C) 2002 Elsevier Science Ltd. All rights reserved.
