摘要
目的:确定印度獐牙菜药材最佳渗漉提取工艺。方法:以HPLC法测定芒果苷含量及出膏率为指标,采用平行比较试验法,优选印度獐牙菜药材的提取方式和提取工艺条件。结果:印度獐牙菜药材最佳提取工艺为采用75%乙醇渗漉法提取,以4 mL/min/kg的流速,收集药材6倍量渗漉液。结论:优选得到的提取工艺简便易行,稳定性好。
AIM ： To determine the optimal extraction of effective component from Swertia chirayita （ Roxb. ex Flemi） Karsten in Tibet. METHODS： HPLC method was used to determine the yield rate and mango glucoside content, the preference extract methods, extraction solvents and extraction method of Swertia chirayita （ Roxb. ex Flemi） Karsten were chose by parallel comparative method. RESULTS： 75% ethanol was used to extract medicine materials by Percolate, the flow rate was 4 mL/min/kg, collecting 6 times liquor after percolate. CONCLUSION ： The extraction method is simple and convenient, furthermore the extract stability is good too.
