连翘败毒丸中原料药材的分子鉴别

Molecular identification of raw materials from Lian Qiao Bai Du Wan

    摘要
  • 摘要:

    为研究分子标记技术在成药鉴定方面的应用, 本文选用连翘败毒丸为研究对象, 采用改良CTAB法提取其总DNA, 通过聚合酶链式反应 (polymerase chain reaction, PCR) 分别对psbA-trnH和rbcL两个叶绿体序列进行梯度扩增, 将扩增产物与pEASYTM-T5 vector连接后,转化到大肠杆菌Trans1-T1感受态细胞中, 挑取单克隆, 并选择阳性克隆进行测序。所得序列校正、比对后, 进行BlastN比对分析, 同时采用MEGA 4.0软件构建系统聚类树。结果表明, 通过psbA-trnH序列分析可以鉴定出9种原料药材, rbcL序列分析可以鉴定出6种原料药材。本研究结果说明采用分子标记技术鉴定中成药原料具有一定的可行性。

     

    Abstract:

    Lian Qiao Bai Du Wan was used to study the identification of Chinese patent medicine by molecular marker technique.  DNA was extracted through modified CTAB method.  The psbA-trnH and rbcL sequences were gradient amplified, and PCR products were ligated with the pEASYTM-T5 vector and then transformed into Trans1-T1 cells, respectively.  Clones were selected randomly and sequenced.  All sequences were analyzed by BlastN and the neighbor-joining (NJ) phylogenetic tree was constructed by MEGA 4.0.  The results showed that nine kinds of medicinal materials can be identified by psbA-trnH sequences, and six kinds of medicinal materials by rbcL sequences from Lian Qiao Bai Du Wan.  Molecular marker technique can stably and accurately distinguish multi-origin medicinal materials in Chinese patent medicine.
