黄金菊粉针药效组分红外指纹表征分析

目的:研究黄金菊粉针(金莲花、野菊花、金银花)药效组分的红外指纹表征,为建立中成药组分指纹鉴定法提供科学数据。方法:采用傅里叶红外光谱(Foru ier transform infrared,FT-IR)及其导数光谱法进行测定,用相关系数法进行解析,用原料药和化学药效组分指纹表征表述质量特征。结果:黄金菊粉针有15个红外特征指纹峰(νcm-1),即3 735,2 931,1 664,1 614,1 450,1 408,1 360,1 291,1 191,1 067,915,768,687,597,417;二阶导数光谱的表征峰是1 416 cm-1。原料药效组分表征峰(νcm-1):金莲花为2 926,1 609;野菊花为1 660,1 609;金银花为767。化学药效组分表征峰(νcm-1):Baicalin为1664,1614,1450,1408,1067,915,768,687,597,417;O rientin为2931,1614,1291,1191;V itexin为1614,1360,1067,597;L inarin为1450,1067,597;Chorogen ic ac id为1614,1291,1191;Caffe ic ac id为1450,1360;Hyperin为1360,1291。结论:采用红外药效组分指纹表征鉴别法可评价黄金菊粉针的质量,可反映出其本质的主要特性,具有明显的专属性。

IR characteristic analysis of the effective constituents in Huangjinju Powder Injection

AIM: To study the FT-IR fingerprinting characteristic of Huangjinju Powder Injection(HJJ)(Flos Trollii chinensis,Flos chrysanthemi indici,Flos Lonicerae Japonicae) and its effective constituents.METHODS: We adopt FT-IR and the second order derivative FT-IR,analysis by the related ratio,and then describe its mass characteristic by its crude drugs and the effective constituents. RESULTS: HJJ has fifteen peaks that are in turn,3735,2931,1664,1614,1450,1408,1360,1291,1191,1067,915,768,687,597 and 417 cm~(-1).Its special peak in the second order derivative is 1416 cm~(-1).The characteristics of the constituents of its crude drug that Flos Trollii Chinensis has 2926 and 1609 cm~(-1),Flos Chrysanthemi Indici has 1660 and 1609 cm~(-1) and Flos Lonicerae Japonicae has 767.The effective constituents that Baicalin owns 1664,1614,1450,1408,1067,915,768,687,597 and 417 cm~(-1),Orientin owns 2931,1614,1291 and 1191 cm~(-1),Vitexin owns 1614,1360,1067 and 597,Linarin owns 1450,1067 and 597 cm~(-1),Chlorogenic acid owns 1614,1291 and 1191 cm~(-1),Caffeic acid owns 1450 and 1360,and Hyperin owns 1360 and 1291. CONCLUSION: The effective constituents of FT-IR can be used in evaluating the mass of Huangjinju Powder Injection and reflect the key characteristic of its essence.It owns the obvious characteristics and specificity.
