摘要
采用正交试验方法 ,对芦笋中芦丁的最佳提取工艺进行了初步研究 ,并采用分光光度法测定芦丁的含量 ,用紫外光谱等对提取的芦丁进行了定性鉴定。研究结果表明 ,在 70～ 75℃条件下用 2 5倍的 75 %乙醇浸提 5h ,提取效果最好 ,浸提率为 94 8% ,测定方法的平均回收率为 10 3 3% ,测定的标准偏差为 1 47× 10 - 3,其变异系数为0 48%。
The optimum extraction conditions of rutin from asparagus were investigated by using orthogonal design.Quantitative analysis of rutin content was achieved by spectrophotometry and qualitative analysis of rutin was achieved by ultraviolet spectro photmetry.The results showed that 70\|75℃,25∶1 of 75% ethanol to asparagus, extraction for 5h were the optimal conditions.The extraction rate was 94\^8%.The average recovery rate was 103\^3%.The standard deviation was 1\^47×10\+\{-3\} and the variation coefficient was 0\^48%.
