目的:确定化学成分在五角。方法:AHigh-performance液体色谱法(高效液相色谱)方法结合quadrupole-time-of-flight-mass光谱法(QTOF-MS)已经开发了精确的分离和结构鉴定的组件在五角。质量光谱法在反射使用电子喷雾离子化飞行时间进行消极的模式。准确massmeasurements(少于5 ppmerror)分子离子和特征碎片离子可以代表可靠识别这些化合物的标准。结果:女士和提供的信息标准的一部分,和22组件标识,如:quercetin-3-O -(2节AA“-O-a-rhamnose 6 AA”-O-malonyl)β-D-glucoside;kaempferol-3-O-of的D-apiose - (1 iA‚®2)- [-alpha-Lrhamnose - (1 iA‚®6)]-beta-D-glucoside;(6)-反式- (2 ia‚®1)p-coumaroyl - a-D-fructofuranosyl-alpha-D-pyran-glucosidase;山柰酚7 - rhamnosidase;kaempferol-3-a -D-glucuronide;芹黄素;4-caffeoyl-5 - coumaroylquinic酸;Kaemoferol-3-arabofuranoside;quercetin-3-O-beta - D-galactose (2 ia‚®1)-一个D-celery糖苷;Dicaffeoylquinic酸;Hyperin;槲皮苷;quercetin-3-glucuronide;异鼠李亭coumaroyldicaffeoylquinic酸;绿原酸;Kaemoferol-3 7-O-diglucuronide; Quercetin;Quercltrin-2"-gallate; Quercetin-3, 7-á-L-dirhamnoside; Stigmasterol;Kaemoferol.CONCLUSION: It is for the first time to identify the estrogenic constituents in Cuscuta Chinensis by HPLC/MS. And this finding could be valuable for the further research of Cuscuta Chinensis.
