摘要: 以猴耳环(Pithecellobium clypearia(Jack) Benth.)茎叶为试材,采用超声波辅助提取法提取总黄酮和没食子酸,在单因素试验的基础上,用响应面法对提取工艺进行优化。结果表明,猴耳环总黄酮提取工艺中各因素影响大小顺序为料液比>超声功率>超声时间>乙醇浓度,猴耳环总黄酮最佳提取工艺为料液比1∶90,乙醇浓度75%,超声功率170 W,超声时间40 min,此条件下总黄酮得率为2.29%(理论值2.37%);没食子酸提取工艺中各因素影响大小顺序为乙醇浓度>料液比>超声时间,没食子酸最佳提取工艺为料液比1∶70,乙醇浓度65%,超声时间60 min,此条件下没食子酸提取率为5.98%(理论值6.04%)。本研究构建的模型拟合效果好,试验值与拟合值高度相关,对猴耳环中总黄酮和没食子酸提取具有较强的指导性,可为其后续研究提供科学依据。

Abstract: Taking the stems and leaves of Pithecellobium clypearia(Jack) Benth. as experiment materials, the total flavonoids and gallic acid were extracted by ultrasonic assisted extraction method. On the basis of single factor experiment, the extraction process was optimized by response surface methodology. The results showed that the order of influence of different factors on extraction of total flavonoids from Pithecellobium clypearia(Jack) Benth. was ratio of material and liquid > ultrasonic power > ultrasound time > ethanol concentration. The optimal extraction condition was ratio of material and liquid 1∶90, ethanol concentration 75%, ultrasonic power 170 W and ultrasound time 40 min. Under this condition, the yield of total flavonoids was 2.29% (theoretical value 2.37%). The order of influencing factors on gallic acid extraction was ethanol concentration > ratio of material and liquid > ultrasound time. The optimal extraction condition was ratio of material and liquid 1∶70, ethanol concentration 65% and ultrasonic time 60 min. Under this condition, the extraction rate of gallic acid was 5.98% (theoretical value 6.04%). The model established in this study had a good fitting effect, and the experimental values were highly correlated with the fitting values, which had strong guidance for the extraction of total flavonoids and gallic acid from Pithecellobium clypearia (Jack) Benth., and could provide a scientific basis for the subsequent research.

Key words: Pithecellobium clypearia (Jack) Benth., total flavonoids, gallic acid, ultrasonic assisted method, response surface optimization
