摘要:目的  测定内蒙不同产地东北点地梅中槲皮素和山柰素含量,为制定蒙药点地梅質量标准提供依据。方法  采用HPLC测定5个产地东北点地梅样品,色谱柱为COSMOSIL 5C18-MS-II(4.6 mm×250 mm,5 μm),流动相为乙腈-0.5%磷酸(40∶60),流速0.8 mL/min,检测波长360 nm,柱温30 ℃。结果  东北点地梅中槲皮素含量为3.58~10.51 mg/g,平均7.14 mg/g;山柰素含量为6.28~9.57 mg/g,平均8.15 mg/g。结论  本研究建立的测定方法简便、准确、重复性好,适于同时测定东北点地梅中槲皮素和山柰素的含量,可为蒙药点地梅质量标准的制定提供依据。

Abstract: Objective To determine the contents of quercetinum and kaempferol in Androsace filiformis Retz. in different producing areas in Inner Mongolia; To provide references for establishing quality standards of Androsace filiformis Retz. Methods HPLC was performed on the column of COSMOSIL 5C18-MS-II (4.6 mm × 250 mm, 5 μm) with mobile phase of acetonitrile - 0.5% phosphonic acid solution (40:60) at a flow rate of 0.8 mL/min; the detection wavelength was 360 nm; column temperature was 30 ℃. Results The contents of quercetinum in Androsace filiformis Retz. from 5 different producing areas were from 3.58 mg/g to 10.51 mg/g, the average content was 7.14 mg/g, and the contents of kaempferol were from 6.28 mg/g to 9.57 mg/g, the average content was 8.15 mg/g. Conclusion The method in this study is simple and accurate, with good reproducibility, and can be used for the simultaneous determination of quercetinum and kaempferol in Androsace filiformis Retz., which can provide a basis for the establishment of quality standards for of Androsace filiformis Retz. in Inner Mongolia.

点地梅属植物Androsace是报春花科的一个中等大属,我国约有70多种。点地梅是蒙医常用药,蒙药名为“达兰-套布其”,惯用品种为东北点地梅Androsace filiformis Retz.和北点地梅Androsace septentrionalis L.,在《无误蒙药鉴》《四部甘露》等蒙医药典籍中均有记载。蒙药点地梅具有清热、解毒、消肿、疗伤、祛协日乌素、滋养强壮功效,主治创伤化脓疼痛、肿毒性关节炎、协日乌素症、赫依协日乌素合并症[1]。

点地梅中主要含有黄酮类和三萜皂苷类成分,其中黄酮类成分主要为槲皮素和山柰素[2-4]。槲皮素具有抗炎、抗病毒、抗肿瘤等生物活性和广泛的药理作用[5],山柰素具有抗炎、抗氧化、抗菌、抗病毒、防癌、抗癌等多种功效[6],两者均为点地梅的有效成分。

点地梅为蒙医习用药材,但迄今尚无该药质量标准,因此限制了其在蒙医药领域的合理利用。本研究对内蒙5个不同产地东北点地梅样品中的槲皮素和山柰素进行含量分析,为蒙药点地梅质量标准的建立提供依据。……
