摘要：

A new quassinoid, 13-beta,18-dihydroeurycomanol, and 14,15-beta-dihydroxyklaineanone have been isolated from the roots of Eurycoma longifolia. On the basis of NOE and H-1-H-1 COSY measurements, the previous H-1 NMR assignment for the C-4 and C-10 methyl groups of eurycomanol-2-O-beta-D-glycopyranoside and eurycomanol are reversed.
