【摘要】 为了找出黄芩饮片水煎煮最佳粒径,通过正交实验设计优化黄芩水煎煮工艺,以黄芩苷溶出量为检测指标,采用高效液相色谱法,检测并比较不同粒径范围黄芩饮片的黄芩苷溶出量.结果发现黄芩饮片优化的水煎煮工艺为煎煮60 min,12倍加水量,煎煮3次.粒径范围为(2,3]mm的黄芩饮片在优化煎煮工艺条件下,黄芩苷溶出量最大.更多还原

【Abstract】 The design for water extraction process of scutellaria baicalensis georgi was carried out by orthogonal test to find out the optimal particle size of scutellaria baicalensis georgi in water extraction,in which baicalin,as the detection index,was determined by high performance liquid chromatography(HPLC),baicalin content in scutellaria baicalensis georgi was analyzed and compared in different particle sizes.The results show that the content of baicalin would reach its maximum,when soaked scutellaria baicalensis georgi with its 12 times′ amount of water is decocted 60 minutes each time,totaling three times.更多还原
