摘要: The structures of momordicosides K and L, bitter principles in the fruits Momordica charantia L. (Cucurbitaceae), were elucidated as 7-O-β-D-glucopyranosides 3β, 7β-dihydroxy-25-methoxy-cucurbita-5, 23-dien-19-al 7β, 25-trihydroxy-cucurbita-5, 23-dien-19-al, respectively, from spectral chemical evidence.
