Study on Technology of Water Extraction and Alcohol Precipitation of Chinese Medicinal Materials in Qingganhnayu Mixture
摘要
Abstract
Objective To optimize the technological conditions of water extraction and alcohol precipitation in Qingganhuayu Mixture. Methods The orthogonal test was adopted to optimize the technology of water extraction and alcohol precipitation. The paeoniflorin content was used as the assessment index and determined by HPLC. Results The optimum water extraction process was A3B3C2D1, i. e., taking the medicinal materials as processed pieces, adding 10 times amount of water as extracting solvent, extracting twice and 2 h each time. The optimum alcohol precipitation process was as follows: the mass fraction was 45％ ethanol, precipitating and static placing for 48 h. Conclusion The paconiflorin content as the assessment index can reflect the effects of various technological conditions. The HPLC method has the advantages of simple operating, accurate analysis, rapidity and less interference.关键词
