[Chemical constituents from flower buds of Lonicera japonica].
Eighteen compounds were isolated by a combination of various chromatographic techniques including column chromatography over macroporous resin, MCI gel, silica gel, and sephadex LH-20 and reversed-phase HPLC. Their structures were elucidated by spectroscopic data analysis as adinoside A (1), stryspinoside (2), benzyl alcohol beta-glucopyranoside (3), benzyl 2-o-beta-D-glucopyranosyl-2,6-dihydroxybenzoate (4) , gentisic acid 2-O-beta-D-glucopyranoside (5), eugenyl beta-D-glucopyranoside (6) , eugenyl-P-xylopyranosyl-(1-->6)-beta-glucopyranoside (7), (-)-lyoniresinol 9-O-fP-D-glucopyranoside (8) , (+)-lyoniresinol 9-O-beta-D-glucopyranoside (9) , apigenin-7-O-L-rhamnopyranoside (10), luteolin-3 '-O-L-rhamnoside (11) , ursolic acid (12) , beta-sitosteryl-3beta-glucopyranoside-6'-O-palmitate (13), abscisic acid (14), guanosine (15), 5-methyluracil (16), trans-cinnamic acid (17), and 4-hydroxybenzaldehyde(18). These compounds were obtained from this plant for the first time.
