目的研究多花黄精Polygonatum cyrtonema地上部分的化学成分。方法采用色谱分离技术进行分离和纯化,并根据波谱学数据鉴定化合物的结构。结果从多花黄精地上部分的甲醇提取物中分离得到15个化合物,分别鉴定为(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)、芹菜素(5)、山柰酚(6)、香草酸(7)、反式对羟基桂皮酸(8)、反式对羟基桂皮酸甲酯(9)、水杨酸(10)、(+)-丁香脂酸(11)、balanophonin B(12)、咖啡酸(13)、苯丙氨酸(14)和松柏醛(15)。结论化合物1、2、7、11、14和15为首次从多花黄精中分离得到,化合物3、4和12为首次从黄精属植物中分离得到。
Objective To study the chemical constituents of Polygonatum cyrtonema aerial parts. Methods Chromatographic separation was used to separate and purify the compounds. The structures of the compounds were identified based on the spectroscopic data. Results Fifteen compounds were isolated from the methanolic extracts of the florentine and 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- -hydroxybenzyl) -chroman-4-one (3), (3S) -3,7-dihydroxy- (5), kaempferol (6), vanillic acid (7), trans-p-hydroxycinnamic acid (8), trans methyl p-hydroxycinnamate (9), salicylic acid (10) Syringic acid (11), balanophonin B (12), caffeic acid (13), phenylalanine (14) and cypressin (15). Conclusion Compounds 1, 2, 7, 11, 14 and 15 were isolated from polygonatum for the first time. Compounds 3, 4 and 12 were isolated from Polygonatum for the first time.
