Abstract:
OBJECTIVETo investigate the chemical constituents of Polygonatum odoratum.
METHODSilica gel column chromatography was used to separate and purify the chemical constituents. The structures were elucidated by chemical and spectral analysis.
RESULTOne dipeptide and one furostanol glycoside were isolated from the rhizomes of P. odoratum, and their structures were identified as O-acetate of N (N-benzoyl-S-phenylalaninyl)-S-phenylalaninol (1) and 22-hydroxy-25 (R and S)-furost-5-en-12-on-3beta,22,26-triol 26-O-beta-D-glucopyranoside (2), respectively.
CONCLUSIONCompound (2) is a new compound and is first reported to be of the furostanol monoglycoside glycosylated at C-26.
