Chemical constiuents from Polygonatum kingianum Coll. & Hemsl.

Abstract

Six compounds, including two homoisoflavanones 3-(2’-hydroxy-4’-methoxy-benzyl)-5,7-dihydroxy-8-methyl-chroman-4-one (1), disporopsin (2) along with 2-O-methyl-α-D-fructofuranose (3), (E,E)-9-oxooctadeca-10,12-dienoic acid (4), 1-palmitoylglycerol (5), 5α,8α-ergosterol peroxide (6) were isolated from the rhizomes of Polygonatum kingianum of Viet Nam. Their structures were determined by 1D- and 2D-NMR spectra and by comparison with the reported spectral data. Compounds 3, 4 and 6 are first reported from the genus Polygonatum. Compound 1 and 5 are reported for the first time from Polygonatum kingianum.
