红花(Carthamus tinctorius L.)为菊科红花属药用红花的干燥花,俗名草红花,功能活血通经,散瘀止痛。临床常用于冠心病,心绞痛,脑血栓等疾病的治疗。红花黄色素(safflor yellow,SY)是红花主要水溶性组分,为混合查尔酮苷。药理研究表明SY有抗凝、抗缺氧、降血压等作用。UV法测定红花中SY的含量已有报道,但该文以混合物SY对照品做标准曲线,使其测定结果偏高。本文以羟基红花黄色素A做对照品,采用UV法测定SY含量,试图为红花质控提供一简便准确的方法。 Carthamus tinctorius L. is a dried flower of the medicinal safflower of Compositae safflower, and its common name is grass safflower, which functions to activate blood circulation and relieve pain. Clinically used for the treatment of coronary heart disease, angina, cerebral thrombosis and other diseases. Safflor yellow (SY) is the main water-soluble component of safflower and is a mixed chalcone glycoside. Pharmacological studies have shown that SY has anticoagulation, anti-hypoxia, and blood pressure lowering effects. The UV method for the determination of SY in safflower has been reported, but the standard curve of the mixture SY reference substance was used to make the determination result high. In this paper, hydroxysafflor yellow A was used as a reference substance, UV content was used to determine SY content, and an attempt to provide a simple and accurate method for quality control of safflower.
