【摘要】 用正交试验法筛选沙棘清喉颗粒的提取工艺参数。分别以HPLC法和分光光度法为含量测定方法,以绿原酸、牛蒡子苷及总黄酮得率为评价指标,对乙醇浓度(%)、料液比(g/mL)、提取时间(h)、提取次数(次)4因素进行考察,选用L9(34)正交实验优化选择清喉颗粒的提取工艺。更多还原

【Abstract】 Orthogonal experiment is used to screen the technical parameters of the extraction of throat-cleansing powder.HPLC and spectrophotometry methods are used to determine content;chlorogenic acid,arctiin,total flavonoids yield are set as indices of evaluation.Ethanol concentration(%),solute-to-solvent ratio(g / mL),extracting time(h),and numbers of times of extractions are examined.L 9(34) orthogonal experiment is used to screen the optimal extracting technique of throat-cleansing powder.更多还原
