密银花对照药材标定标准的研究(1)
[摘要] 建立道地药材密银花对照药材标定技术规范,作为密银花对照药材内在质量控制和评价的理论依据及技术标准,为道地药材现代研究及其特征辨识提供支撑。收集10批密银花,根据2015年版《中国药典》一部方法进行检验,10批样品均符合规定;建立LC-MS指纹图谱检测方法,确定了23 个共有峰,并根据对照品和参考文献指认了8个共有峰,对10批密银花药材相似度进行了考察,其相似度在0.95以上。使用7对金银花种质鉴定核心引物进行SSR指纹图谱构建,10批密银花指纹图谱均与河南尖山大毛花种质SSR参照图谱差异位点数为1或0个,符合密银花种质分子特征。通过结合DNA指纹图谱和LC-MS化学指纹图谱,建立了首个中药道地药材的标定标准,该标定标准的制定为加快中药标准药材尤其是道地药材的评价体系的建设提供了理论依据及技术标准。

[Abstract] The calibration technical specification for reference drug of Lonicera japonica cultivated in Xinmi (Mi Yin Hua) established in this study can be used as the theoretical basis and technical standard for internal quality control and evaluation of reference drug of Mi Yin Hua and for modern research and characteristics identification of Dao-di herbs. Based on the quality standard of L. japonica in Chinese Pharmacopoeia (version 2015), 10 batches samples of Mi Yin Hua also conformed to the stipulation. The LC-MS fingerprint common mode of Mi Yin Hua was obtained, and a total of 23 characteristic peaks were selected as the common fingerprint peaks, and eight common chromatographic peaks in the fingerprint was identified based on standard substances and references. The similarities of 10 batches samples were greater than 0.95. Seven core primers were used to construct SSR fingerprint and the ten batches samples were only 0 or 1 site disaccord with the standard diagram of Jianshan Damaohua germplasm from Xinmi. This paper constructed the first calibration standard of Dao-di herbals by combination of macroscopical identification, SSR fingerprint and LC-MS fingerprint, and the calibration standard provide theoretical basis and technical standard for evaluation system of Dao-di herbals.

金银花为忍冬科植物忍冬Lonicera japonica Thunb.的干燥花蕾或带初开的花,具有清热解毒、凉散风热的功效[1]。金银花是常用大品种中药材,主產于河南、山东、河北等省,其中河南“密银花”是被广泛认可的道地药材。早在南宋,《曲洧旧闻》中就明确记载金银花产于“郑许田野间”[2],郑许即南宋时期的郑州和许州,其与现今河南省郑州市、许昌市位置大致相当。而《救荒本草》记载金银花生于“辉县山野中”[3],明代辉县与今之河南省辉县市位置也大致相当。《植物名实图考》记载金银花“皆中州产也”,这里的中州即指今河南省。由此可见,宋、明、清三代均有文献明确记载河南产金银花,且《植物名实图考》中提到“茶肆以新贩到金银花为贵,皆中州产也”[4],可依此判断当时已经认为河南的金银花是质优效佳之品。密银花的明确记载已从南宋延续至今,古代本草中比较明确的产地有河南省的郑州市、许昌市和辉县市,位于东经115°北纬35°左右的区域。
道地药材是中医药伟大宝库中重要的组成部分,在国家药品标准物质要求的基础上,建立对照道地药材是实现道地药材特征辨识的必要前提。对道地药材的评价应是在符合《中国药典》要求的基础上,对优质药材进行鉴定与评价,但现有的化学对照品、对照药材等标准物质已不能满足道地药材评价的需求,因此需要建立更高要求的标准物质。本研究采集来自金银花传统道地产区——河南省新密市的10批密银花,分析研究各批次样品的特征特性,建立密银花的DNA指纹图谱和LC-MS化学指纹图谱,制定了密银花对照药材标定技术标准,作为密银花对照药材内在质量控制和评价的理论依据及技术标准,为道地药材现代研究及其特征辨识提供支撑。, 百拇医药(杨健 蒋超 金艳 赵玉洋 袁媛 黄璐琦)
