- 摘要:
- 为探讨提取芦荟中芦荟苷的最佳工艺条件，以芦荟苷含量为指标，超声波辅助法进行正交试验，确定芦荟苷提取工艺。结果表明：超声波提取的最佳工艺条件为：乙醇浓度80％，料液比1:55，超声温度35℃，超声时间40 min。在此条件下，用紫外分光光度法测定所提取芦荟苷的含量为8.520 mg?g-1。芦荟苷正交提取工艺的研究结果可靠。
- Abstract:
- In order to investigate the optimum conditions to extract aloin from Aloe,taking aloin content as an indicator,the effect of ultrasonic-assisted extraction on aloin in Aloe were studied，and the optimal extraction conditions was determined．The results showed that the optimum conditions for ultrasonic extraction: ethanol concentration was 80％,solid-liquid ratio was 1:55，uhrasonic temperature was 35℃ and uhrasonic time was 40 min.Determination of aloin by UV spectrophotometry,the extraction rate could reach 8.520 mg?g-1 under these conditions.The results of orthogonal extraction process of aloin were reliable.
