Megastigmane glycosides from Lonicera gracilipes var. glandulosa

Matsuda, N. | Isawa, K. | Kikuchi, M.

Two new megastigmane glycosides, (6R, 7E, 9R)-9-hydroxy-4, 7-megastigmadien-3-one 9-O-[alpha-L-arabinopyranosyl-(1 leads to 6) -beta-D-glucopyranoside] and (6S, 7E, 9R)-6,9-dihydroxy-4, 7-megastigmadien-3-one 9-O-[alpha-L-arabinopyranosyl-(1 leads to 6)-beta-D-glucopyranoside), were isolated from the leaves of Lonicera gracilipes var. glandulosa. Their absolute stereostructures were elucidated on the basis of spectral and chemical evidence.
