  摘 要 目的:建立同时测定杉寄生药材中2种黄酮类成分落新妇苷和芦丁含量的反相高效液相色谱(RP-HPLC)法,并比较不同产地药材中2种成分的含量。方法:色谱柱为SHISEIDO-SPOLAR C18,流动相为乙腈-0.1%磷酸溶液(14 ∶ 86,V/V),流速为1.0 mL/min,检测波长为291 nm,柱温为35 ℃,进样量为10 μL;对来源于广西和广东6个市/县的杉寄生药材进行含量测定及比较分析。结果:落新妇苷和芦丁的检测质量浓度线性范围分别为22~440、12~240 μg/mL(r分别为0.999 6、0.999 1),平均加样回收率分别为99.44%、99.96%(RSD分别为1.38%、1.50%,n=9);杉寄生中落新妇苷含量在各省/区及各市/县之间均相似(0.862 5~0.901 1 mg/g),芦丁含量在同一省/区的市/县间相似,但在2个省/区之间差异较大(平均值分别为0.431 3 、0.214 9 mg/g)。结论:本法简便、准确、稳定、重现性好,可用于杉寄生药材的质量控制。

  ABSTRACT OBJECTIVE: To establish RP-HPLC method for simultaneous determination of astilbin and rutin in Macrosolen cochinchinensis, and to compare the contents of 2 components in medicinal material from different producing areas. METHODS: The determination was performed on SHISEIDO-SPOLAR C18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid (14 ∶ 86, V/V) at the flow rate of 1.0 mL/min. The detection wavelength was set at 291 nm, and column temperature was 35 ℃, the sampling volume is 10 μL.Content determination and comparative analysis of M. cochinchinensis from 6 counties of Guangxi and Guangdong were conducted. RESULTS: The linear range of astilbin and rutin were 22-440 μg/mL (r=0.999 6) and 12-240 μg/mL (r=0.999 1); average recoveries were 99.44% (RSD=1.38%, n=9) and 99.96% (RSD=1.50%, n=9). The contents of astilbin in M. cochinchinensis were similar between provinces/autonomous region or among cities/counties (0.862 5- 0.901 1 mg/g); the contents of rutin were similar among cities/counties in same provinces/autonomous region but there was a great difference between provinces/autonomous region (average values were 0.431 3, 0.214 9 mg/g). CONCLUSIONS: This method is simple, accurate, stable and reproducible for the quality control of M. cochinchinensis.

  杉寄生藥材为桑寄生科植物鞘花[Macrosolen cochinchinensis (Lour.) Van Tiegh.]的茎枝,收载于《中华本草》,具有祛风湿、补肝肾、活血止痛、止咳、止痢的功效,主要分布于华南、西南地区,为民间和临床常用中药[1]。目前对该药材的研究主要为性状、显微及成分分析,对其有效成分的含量测定及药材质量标准的相关研究较少,故有关其质量控制的研究意义更大。
  杉寄生药材中黄酮类成分主要为落新妇苷和芦丁[2-3]。研究表明,落新妇苷具有选择性免疫抑制作用、调节脂肪及胆固醇代谢作用[4],以及抗炎、利尿、镇痛等作用[5];芦丁具有抗心肌缺氧、缺血、降低血清胆固醇、抑制血小板集聚、抗炎、抗过敏、抗病毒和增强免疫力等活性作用[6],这2种成分的活性与杉寄生的功效密切相关。因此,笔者在本文中建立了同时测定杉寄生中落新妇苷和芦丁含量的反相高效液相色谱(RP-HPLC)法,并对来源于不同产地的6批杉寄生药材进行分析与比较,为有效控制杉寄生药材的质量提供依据。
