摘 要:采用分光光度法,以芦丁为标准样品测定新疆准噶尔铁线莲不同部位中的总黄酮的含量,采用正交试验设计对其不同部位中总黄酮提取工艺进行最佳筛选,四种因素对不同部位总黄酮含量测定均有影响,分别得到的最佳提取工艺条件为:茎:乙醇浓度50%,温度50℃,浸提时间3h,料液比1:50,吸光度0.270;叶:乙醇浓度60%,温度70℃,浸提时间3h,料液比1:30,吸光度0.562。花:乙醇浓度50%,温度60℃,时间2h,料液比1:50,吸光度0.480;果实:乙醇浓度60%,温度70℃,浸提时间3h,料液比1:40,吸光度0.365。In this study, the total flavonoids content was assayed by using spectrophotometry method with rutin as standard. The extraction technology of the total flavonoids from different parts of Clematis songarica Btmge, such as stem, leaf, flower and fruit was optimized by means of orthogonal test. Results showed that for the stem, the optimal extraction conditions are: ethanol concentration 50%, extraction temperature 50 ℃, extraction time 3 h and ratio of material to ethanol solution 1:50, and the absorbance of the total flavonoids extract is 0.270 under the optimal conditions. For the leaf, the optimal extraction condition are: ethanol concentration 60%, extraction temperature 70 ℃, extraction time 3 h and ratio of material to ethanol solution 1:30, and the absorbance of the total flavonoids extract is 0.562 under the optimal conditions. For the flower, the optimal extraction conditions are: ethanol concentration 50%, extraction temperature 60 ℃, extraction time 2 h and ratio of material to ethanol solution 1:50, and the absorbance of the total flavonoids extract is 0.480 under the optimal conditions. For the fruit, the optimal extraction conditions are: ethanol concentration 60%, extraction temperature 70 ℃, extraction time 3 h and ratio of material to ethanlo solution 1:40, and the absorbance of the total flavonoids extract is 0.365 under the optimal conditions.
