摘要: 本研究优化了天花粉中总黄酮的提取工艺,采用Al(NO3)3-NaNO2 比色法测定了天花粉中总黄酮的含量。在单因素试验的基础上,采用L9(34)正交试验,以天花粉中总黄酮提取率为指标,探讨了甲醇体积分数、料液比、提取温度、提取时间对天花粉中总黄酮提取率的影响。结果表明最佳提取工艺参数为:甲醇体积分数50%、料液比1:15、提取温度70 ℃、提取时间90 min。在最佳工艺条件下测得天花粉中总黄酮平均含量为0.1184 mg/g。该方法操作简单,稳定性和重复性好,本实验首次测定了天花粉中总黄酮含量,为天花粉药材质量控制提供了依据。

Abstract: In this study,the extraction technology of total flavonoids from Radix Trichosanthis was optimized,and the content of total flavonoids was measured using Al(NO3)3-NaNO2 colorimetric method.Based on the single factor experiment,the effect of the volume fraction of methanol,solid-liquid ratio,extraction exmperature,extraction time on the extraction yield of total flavonoids were studied using L9(34) orthogonal experiment.The results showed that the optimal extraction parameters were as followed:volume fraction of methanol was 50%,ratio of solid to liquid was 1:15,extraction temperature was 70 oC,and extraction time was 90 min.The total content of flavone was 0.1184 mg/g under the optimal extraction conditions.The developed method was simple,stable and high repeatable.The content of total flavonoids in Radix Trichosanthis was determined in this study for the first time,which provided the basis for the quality control of Radix Trichosanthis.

Key words: Radix Trichosanthis, total flavonoids, orthogonal test, technical study
