The new secondary metabolite from Polygonatum odoratum / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the chemical constituents of Polygonatum odoratum.</p><p><b>METHOD</b>Silica gel column chromatography was used to separate and purify the chemical constituents. The structures were elucidated by chemical and spectral analysis.</p><p><b>RESULT</b>One 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.</p><p><b>CONCLUSION</b>Compound (2) is a new compound and is first reported to be of the furostanol monoglycoside glycosylated at C-26.</p>
