ABSTRACT
OBJECTIVE:
To study the chemical constituents of bamboo juice.METHODS:
The compounds were isolated and purified by column chromatography on silica gel, ODS, macroporous resin, MPLC and HPLC. Their structures were elucidated by NMR spectroscopic evidence and compared with those in literature.RESULTS:
Fifteen compounds were isolated and identified as (+)-lyoniresinol-3α-O-β-D-glucopyranoside (1), 5, 5'-dimethoxylariciresinol-4'-O-β-D-glucopyranoside (2), syringaresinol 4'-O-β-D-glucopyroside (3), (-)-4-epi-lyoniresinol (4), (-)-lyoniresinol -2α-O-β-D-glucopyranoside (5), (+)-lyoniresinol (6), 8, 8'-bisdihydrosiringenin glucoside (7), 2, 4, 6-trimethoxyphenyl-1-O-β-D-glucopyranoside (8), threo-8S-7-meth-oxysyringylglycerol (9), salidroside (10), (7S, 8R)syringoylglycerol (11), syringaldehyde (12), 2, 6-dimethoxy-1, 4-benzoquinone (13), n-butyl-β-D-fructopyranoside (14), and n-butyl pyroglutamate (15).CONCLUSION:
Compounds 1-11 and 14-15 are isolated from bamboo juice for the first time. Compounds 14 and 15 are β-D-fructopyranoside and pyroglutamic acid artifacts produced during the extraction.
