消渴降糖胶囊制备工艺的研究

目的 研究消渴降糖胶囊制备工艺.方法 采用高效液相色谱仪,以甲醇-0.4%磷酸溶液(60∶40)为流动相,检测波长为367 nm进行测定,记录色谱图,计算峰面积.结果 提取3 h、提取2 h与提取1 h相比,槲皮素提取率有显著增高(P<0.05),但提取3 h与提取2 h槲皮素的含量无显著性变化,浸膏得率3 h比2 h显著提高(P<0.05);加醇量4.0倍与3.0倍相比较,浸膏得率显著降低(P<0.05),槲皮素含量相差不大.结论 在制备消渴降糖胶囊工艺中,应减少能源消耗,降低无效成分的提取率,减少浸膏量.在尽量减少杂质,保留有效成分,降低服用量的综合考虑下,采用4.0倍量乙醇进行醇沉有效成分损失少,浸膏得率低,符合工业化要求.

STUDY ON THE PREPARATION FOR THE XIAOKEJIANGTANG CAPSULES

Objective To study the preparation technology for the xiaokejiangtang capsules,a traditional Chinese medicine.Methods The high performance liquid chromatography,was used and the mobile phase consisted of 0.4% phosphoric acid-methanol.The wave length for measurement was 367 nm.The chart was registered and the peak area was calculated.Results Compared with the yield of the extraction for one hour,the yields of quercetin for 3 or 2 hours were obviously higher(P<0.05),whilethe extraction for 3and 2-hours showed...
