  摘 要 目的:建立同時測定杉寄生藥材中2種黃酮類成分落新婦苷和蘆丁含量的反相高效液相色譜(RP-HPLC)法,并比較不同產(chǎn)地藥材中2種成分的含量。方法:色譜柱為SHISEIDO-SPOLAR C18,流動相為乙腈-0.1%磷酸溶液(14 ∶ 86,V/V),流速為1.0 mL/min,檢測波長為291 nm,柱溫為35 ℃,進樣量為10 μL;對來源于廣西和廣東6個市/縣的杉寄生藥材進行含量測定及比較分析。結(jié)果:落新婦苷和蘆丁的檢測質(zhì)量濃度線性范圍分別為22~440、12~240 μg/mL(r分別為0.999 6、0.999 1),平均加樣回收率分別為99.44%、99.96%(RSD分別為1.38%、1.50%,n=9);杉寄生中落新婦苷含量在各省/區(qū)及各市/縣之間均相似(0.862 5~0.901 1 mg/g),蘆丁含量在同一省/區(qū)的市/縣間相似,但在2個省/區(qū)之間差異較大(平均值分別為0.431 3 、0.214 9 mg/g)。結(jié)論:本法簡便、準(zhǔn)確、穩(wěn)定、重現(xiàn)性好,可用于杉寄生藥材的質(zhì)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.

  杉寄生藥材為桑寄生科植物鞘花[Macrosolen cochinchinensis (Lour.) Van Tiegh.]的莖枝,收載于《中華本草》,具有祛風(fēng)濕、補肝腎、活血止痛、止咳、止痢的功效,主要分布于華南、西南地區(qū),為民間和臨床常用中藥[1]。目前對該藥材的研究主要為性狀、顯微及成分分析,對其有效成分的含量測定及藥材質(zhì)量標(biāo)準(zhǔn)的相關(guān)研究較少,故有關(guān)其質(zhì)量控制的研究意義更大。
  杉寄生藥材中黃酮類成分主要為落新婦苷和蘆丁[2-3]。研究表明,落新婦苷具有選擇性免疫抑制作用、調(diào)節(jié)脂肪及膽固醇代謝作用[4],以及抗炎、利尿、鎮(zhèn)痛等作用[5];蘆丁具有抗心肌缺氧、缺血、降低血清膽固醇、抑制血小板集聚、抗炎、抗過敏、抗病毒和增強免疫力等活性作用[6],這2種成分的活性與杉寄生的功效密切相關(guān)。因此,筆者在本文中建立了同時測定杉寄生中落新婦苷和蘆丁含量的反相高效液相色譜(RP-HPLC)法,并對來源于不同產(chǎn)地的6批杉寄生藥材進行分析與比較,為有效控制杉寄生藥材的質(zhì)量提供依據(jù)。
