摘要
目的 制备20批不同产地的肾茶饮片标准汤剂,并建立其质量标准.方法 按标准汤剂制备方法和要求,制备20批肾茶饮片的标准汤剂.考察其出膏率、迷迭香酸含量及其转移率,并建立高效液相色谱(HPLC)特征图谱.结果 20批肾茶饮片标准汤剂的出膏率、迷迭香酸含量及其转移率分别为18.42%～22.38%,2.30～8.03 mg/g,36.89%～57.31%,拟定出膏率、迷迭香酸含量及转移率的标准分别为14.0%～27.0%,2.0～9.2 mg/g,31.0%～64.0%.HPLC特征图谱有7个共有峰,其中3个共有峰分别为咖啡酸、迷迭香酸和紫草酸,且特征图谱相似度均大于0.970.结论 本研究建立的肾茶饮片标准汤剂的质量标准准确、可靠,能为肾茶饮片配方颗粒及其相关制剂质量研究提供参考和依据.
Abstract
Objective To prepare twenty batches of standard decoction of Orthosiphon Stamineus medicinal slices collected from different origins and establish its quality standard.Methods Twenty batches of standard decoction of Orthosiphon Stamineus medicinal slices were prepared according to the preparation methods and requirements for standard decoction.The extraction rates and contents and transfer rates of rosmarinic acid were evaluated and the HPLC characteristic chromatogram was established.Results The extraction rates of twenty batches of standard decoction of Orthosiphon Stamineus medicinal slices and contents and transfer rates of rosmarinic acid were 14.0%-27.0%,2.0-9.2 mg/g,and 31.0%-64.0%,respectively.It was preliminarily proposed that the standards of extraction rate,content and transfer rate of rosmarinic acid were 14.0%-27.0%,2.0-9.2 mg/g,and 31.0%-64.0%,respectively.Seven common peaks were determined in the characteristic chromatogram and the peaks of caffeic acid,rosemary acid and purple oxalic acid were identified.The similarities of the peaks in the characteristic chromatogram were all higher than 0.970.Conclusion The established quality standard of standard decoction of Orthosiphon Stamineus medicinal slices was accurate and reliable,which can provide reference and basis for the quality research of formula granules and related preparations.
