摘 要 目的:建立同時(shí)測(cè)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(dòng)相為乙腈-0.1%磷酸溶液(14 ∶ 86,V/V),流速為1.0 mL/min,檢測(cè)波長(zhǎng)為291 nm,柱溫為35 ℃,進(jìn)樣量為10 μL;對(duì)來(lái)源于廣西和廣東6個(gè)市/縣的杉寄生藥材進(jìn)行含量測(cè)定及比較分析。結(jié)果:落新婦苷和蘆丁的檢測(cè)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(gè)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(jiǎn)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(bǔ)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(duì)該藥材的研究主要為性狀、顯微及成分分析,對(duì)其有效成分的含量測(cè)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(guò)敏、抗病毒和增強(qiáng)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(shí)測(cè)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(duì)來(lái)源于不同產(chǎn)地的6批杉寄生藥材進(jìn)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)。
