- 摘要:
- 为确定白及的最佳提取工艺,以白及为试验材料,建立基于HPLC指纹图谱的白及化学成分提取优化工艺。运用指纹图谱技术对白及提取工艺方法进行最优筛选,联合应用单因素分析法以及其他统计学方法考察了提取的甲醇浓度、温度、提取时间和药材粒度对提取效果的影响。建立了白及的指纹图谱,选择了16个特征峰,且确定了白及最佳提取工艺为采用过6号筛的白及粉末以80%浓度甲醇在55 ℃水浴加热3.0 h。通过单因素分析以及曲线拟合的结果可以推测,甲醇浓度、温度、提取时间和药材粒度对于提取结果均有影响。该工艺稳定可靠,简便易行,可以在一定程度上对白及的品质进行评价。
- Abstract:
- In order to determine the best extraction process of Bletilla striata,we used Bletilla striata as the experimental materials,to establish Bletilla striata HPLC fingerprint and optimize the extraction process.The fingerprinting technique was used to screen the optimal extraction process method of Bletilla striata,combined with single factor analysis and other statistical methods to investigate the extracted methanol concentration,temperature,extraction time and the size of the medicinal materials.The results showed taht the fingerprint of Bletilla striata was established,and 16 characteristic peaks were selected.The optimal extraction process of Bletilla striata was determined to be Bletilla striata powder with No.6 sieve and heated with 80% methanol in 55 ℃ water bath for 2.5 hours.Through the results of single factor analysis and curve fitting,it could be inferred that methanol concentration,temperature,extraction time and medicinal material particle size all had an impact on the extraction results.The process was stable and reliable,simple and easy to perform,and could evaluate the chemical composition and quality of Bletilla striata to a certain extent.
