【摘要】 目的:研究正品肉苁蓉及其习用品盐生肉苁蓉和管花肉苁蓉中的苯乙醇苷类化合物的种类和含量。方法:采用LC/ESI-MS/MS方法对正品肉苁蓉及其习用品盐生肉苁蓉和管花肉苁蓉中的7种苯乙醇苷类化合物进行定性分析及相对含量测定。结果:正品肉苁蓉中鉴别出7种苯乙醇苷类化合物;而盐生肉苁蓉中只含6种;管花肉苁蓉中只含5种,而且3种肉苁蓉中苯乙醇苷含量也有差别。结论:3种肉苁蓉中苯乙醇苷类化合物的种类和含量是区别各种肉苁蓉的特征成分之一。更多还原

【Abstract】 AIM To analyze the phenylethanoid glycosides in Cistanche deserticola Y. D.Ma and its alternatives.METHODS An HPLC/MS/MS method has been developed for the analysis of seven kinds of phenylethanoid glycosides in Cistanche deserticola Y.D.Ma,C. salsa(C.A.Mey) G.Beck and C.tubulosa(Schenk) R.Wight.The[M-H]~-ions were observed for five standards and Cistanche extracts.The glycosidic linkages,the core,and the attached sugar(s) of the phenylethanoid glycosides can be determined from the collision-induced dissociation spectra of the molecular.RESULTS Seven kinds of phenylethanoid glycosides (echinacoside,acteoside,cisacteoside,isoacteoside,2’-acetylacteoside,cistanoside A,osmanthuside B) in Cistanche deserticola Y.D.Ma,six kinds(echinacoside,acteoside,cisacteoside, isoacteoside,2’-acetylacteoside and cistanoside A) in C.salsa(C.A.Mey) G.Beck and five kinds(echinacoside,acteoside,cisacteoside,isoacteoside and 2’-acetylacteoside) in C.tubulosa (Schenk) R.Wight were detected.CONCLUSION The difference of the relative distribution of these phenylethanoid glycosides in each extract was found out.Phenylethanoid glycosides are the specific constituents in Cistanchis,which can be used to distinguish different species in Genus Cistanchis.更多还原
