  [摘要] 建立道地藥材密銀花對(duì)照藥材標(biāo)定技術(shù)規(guī)范,作為密銀花對(duì)照藥材內(nèi)在質(zhì)量控制和評(píng)價(jià)的理論依據(jù)及技術(shù)標(biāo)準(zhǔn),為道地藥材現(xiàn)代研究及其特征辨識(shí)提供支撐。收集10批密銀花,根據(jù)2015年版《中國(guó)藥典》一部方法進(jìn)行檢驗(yàn),10批樣品均符合規(guī)定;建立LC-MS指紋圖譜檢測(cè)方法,確定了23 個(gè)共有峰,并根據(jù)對(duì)照品和參考文獻(xiàn)指認(rèn)了8個(gè)共有峰,對(duì)10批密銀花藥材相似度進(jìn)行了考察,其相似度在0.95以上。使用7對(duì)金銀花種質(zhì)鑒定核心引物進(jìn)行SSR指紋圖譜構(gòu)建,10批密銀花指紋圖譜均與河南尖山大毛花種質(zhì)SSR參照?qǐng)D譜差異位點(diǎn)數(shù)為1或0個(gè),符合密銀花種質(zhì)分子特征。通過(guò)結(jié)合DNA指紋圖譜和LC-MS化學(xué)指紋圖譜,建立了首個(gè)中藥道地藥材的標(biāo)定標(biāo)準(zhǔn),該標(biāo)定標(biāo)準(zhǔn)的制定為加快中藥標(biāo)準(zhǔn)藥材尤其是道地藥材的評(píng)價(jià)體系的建設(shè)提供了理論依據(jù)及技術(shù)標(biāo)準(zhǔn)。

  [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.

  金銀花為忍冬科植物忍冬Lonicera japonica Thunb.的干燥花蕾或帶初開(kāi)的花,具有清熱解毒、涼散風(fēng)熱的功效[1]。金銀花是常用大品種中藥材,主產(chǎn)于河南、山東、河北等省,其中河南“密銀花”是被廣泛認(rèn)可的道地藥材。早在南宋,《曲洧舊聞》中就明確記載金銀花產(chǎn)于“鄭許田野間”[2],鄭許即南宋時(shí)期的鄭州和許州,其與現(xiàn)今河南省鄭州市、許昌市位置大致相當(dāng)。而《救荒本草》記載金銀花生于“輝縣山野中”[3],明代輝縣與今之河南省輝縣市位置也大致相當(dāng)!吨参锩麑(shí)圖考》記載金銀花“皆中州產(chǎn)也”,這里的中州即指今河南省。由此可見(jiàn),宋、明、清三代均有文獻(xiàn)明確記載河南產(chǎn)金銀花,且《植物名實(shí)圖考》中提到“茶肆以新販到金銀花為貴,皆中州產(chǎn)也”[4],可依此判斷當(dāng)時(shí)已經(jīng)認(rèn)為河南的金銀花是質(zhì)優(yōu)效佳之品。密銀花的明確記載已從南宋延續(xù)至今,古代本草中比較明確的產(chǎn)地有河南省的鄭州市、許昌市和輝縣市,位于東經(jīng)115°北緯35°左右的區(qū)域。
  道地藥材是中醫(yī)藥偉大寶庫(kù)中重要的組成部分,在國(guó)家藥品標(biāo)準(zhǔn)物質(zhì)要求的基礎(chǔ)上,建立對(duì)照道地藥材是實(shí)現(xiàn)道地藥材特征辨識(shí)的必要前提。對(duì)道地藥材的評(píng)價(jià)應(yīng)是在符合《中國(guó)藥典》要求的基礎(chǔ)上,對(duì)優(yōu)質(zhì)藥材進(jìn)行鑒定與評(píng)價(jià),但現(xiàn)有的化學(xué)對(duì)照品、對(duì)照藥材等標(biāo)準(zhǔn)物質(zhì)已不能滿足道地藥材評(píng)價(jià)的需求,因此需要建立更高要求的標(biāo)準(zhǔn)物質(zhì)。本研究采集來(lái)自金銀花傳統(tǒng)道地產(chǎn)區(qū)——河南省新密市的10批密銀花,分析研究各批次樣品的特征特性,建立密銀花的DNA指紋圖譜和LC-MS化學(xué)指紋圖譜,制定了密銀花對(duì)照藥材標(biāo)定技術(shù)標(biāo)準(zhǔn),作為密銀花對(duì)照藥材內(nèi)在質(zhì)量控制和評(píng)價(jià)的理論依據(jù)及技術(shù)標(biāo)準(zhǔn),為道地藥材現(xiàn)代研究及其特征辨識(shí)提供支撐。
