ABSTRACT
From an aqueous extract of Lonicera japonica flower buds, sixteen 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 6'-O-acetylvogeloside (1), 6'-O-acetylsecoxyloganin (2), dichlorogelignate (3), guanosinyl-(3' --> 5')-adenosine monophosphate(GpA,4) , 5'-O-methyladenosine (5), 2'-O-methyladenosine (6), adenosine (7), syringin (8), methyl 4-O-β-D-glucopyranosyl caffeate (9), (-)-dihydrophaseic acid 4'-O-β-D-glucopyranoside (10), ketologanin (11), 7α-morroniside (12), 7β-morroniside (13), kingiside (14), cryptochlorogenic acid methyl ester (15), and 6-hydroxymethyl-3-pyridinol (16). All the compounds were obtained from this plant for the first time, compounds 1 and 2 are new compounds, 3 and 5 are new natural products, and 4 is the first example of dinucleoside monophosphate isolated from a plant extract.
