目的研究野艾蒿的化学成分。方法采用色谱方法进行分离、纯化,通过波谱技术对化合物进行结构鉴定。结果从野艾蒿中分离得到11个黄酮类化合物,其结构鉴定分别为山柰酚(kaempferol,1)、芒柄花素(formononetin,2)、异鼠李素(isorhamnetin,3)、洋芹素(apigenin,4)、苜蓿素(tricin,5)、槲皮素-7-O-β-D-葡萄糖苷(6),槲皮素-7-O-α-L-鼠李糖苷(7),槲皮素-3-O-β-D-葡萄糖苷(8),山柰酚-3-O-β-D-葡萄糖苷(9),芹菜素-7-O-β-D-葡萄糖苷(10),山柰酚-3-O-芸香糖苷(11)。结论化合物1～11均为首次从该植物中分离得到。 Objective To study the chemical constituents of Artemisia annua. Methods Chromatographic methods were used to separate and purify the compounds. The structures were identified by spectroscopic techniques. Results Eleven flavonoids were isolated from Artemisia annua and their structures were identified as kaempferol (1), formononetin (2), isorhamnetin (3), celery Apigenin 4, tricin 5, quercetin -7-O-β-D-glucoside 6, quercetin -7-O-α-L-rhamnoside 7 (8), kaempferol-3-O-β-D-glucoside (9), apigenin-7-O-β-D-glucose Glycoside (10), behenophenol-3-O-rutinoside (11). Conclusion Compounds 1 ~ 11 were isolated from this plant for the first time.
