根据姜黄清脂片中姜黄的提取特点,选用85%乙醇作为提取溶剂,浸渍24 h后进行提取。以提取物中姜黄素的含量为考察指标,对可能影响姜黄渗漉效果的4个主要因素浸泡时间、乙醇浓度、乙醇用量及渗漉速度进行了正交设计优化,确定了最佳提取条件为用85%乙醇作溶剂,浸渍24 h后,用药材8倍量的85%乙醇进行渗漉,渗漉速度为每小时漉出量是药材重量的1倍。
According to the extraction characteristics of curcuma longa in turmeric clear fat tablets, 85% ethanol was chosen as the extraction solvent, and then extracted for 24 h after immersion. Taking the content of curcumin in the extract as the investigation index, orthogonal design optimization was made on the four main factors that may affect the infiltration of turmeric, such as the soaking time, the ethanol concentration, the ethanol dosage and the percolation rate. The optimum extraction conditions were determined as With 85% ethanol as solvent, after dipping for 24 h, it was percolated with 8 times the amount of 85% ethanol, the percolation rate was 1 times of the weight of medicinal material per day.
