| 摘 要： | 采用微波法,用乙醇提取生姜总黄酮,并对其光热稳定性进行了研究。结果表明,用1∶40(g/mL)的50%的乙醇水溶液,微波功率为464 W,萃取时间为60 s提取效果较好,此条件下总黄酮得率为1.59%;生姜黄酮在避光和加热条件下比较稳定,自然光、短时间紫外光和日光照射对生姜黄酮的影响不大。

| Abstract: | The total flavone was extracted from ginger by microwave method with ethanol as extracter,and its stability of light and heating was also studied.The results showed that the content of flavone in extraction solution is 1.59% at 464 W microwave for 60 s when 50% alcohol solution is used with the solid-liquid ratio of 1 : 40 (g/mL).Flavone from ginger was stable at condition of photophobic and heating.The influence of natural light,ultraviolet in short time and sunlight on flavone from ginger is small. |
