To study the chemical constituents from the aerial part of Polygonatum cyrtonema.Methods:
The compounds were isolated and purified by means of chromatographic techniques and their structures were identified on the basis of spectral features.Results:
Fifteen known compounds were isolated in methanol extract from the aerial part of P. cyrtonema and their structures were identified as (3R)-5,7-dihydroxy-3-(2'-hydroxy-4'-methoxybenzyl)-chroman-4-one (1), 5,7-dihydroxy-6-methyl-3-(2',4'-dihydroxybenzyl)- chroman-4-one (2), 5,7-dihydroxy-6-methyl-3-(4'-hydroxybenzyl)-chroman-4-one (3), (3S)-3,7-dihydroxy-8-methoxy-3-(3',4'- methylenedioxybenzyl)-chroman-4-one (4), apigenin (5), kaempferol (6), vanillic acid (7), trans-p-hydroxycinnamic acid (8), trans-p-hydroxycinnamic acid methyl ester (9), saliylic acid (10), (+)-syringaresinol (11), balanophonin B (12), caffeic acid (13), phenylalanine (14), and coniferaldehyde (15).Conclusion:
Compounds 1, 2, 7, 11, 14, and 15 are firstly obtained from P. cyrtonema. Compounds 3, 4, and 12 are isolated from the plants of Polygonatum Mill. for the first time.
