| 摘 要： | 用紫外光谱研究了光、温度、pH、Na2SO3、FeSO4及抗坏血酸对黄芩素稳定性的影响.在室温条件下,黄芩素溶液的吸光度值在6h内强度有明显的下降;当温度升高或在避光条件下,偏酸性黄芩素溶液的吸光度值在6h内强度不变,而碱性条件下依然有下降趋势;但黄芩素溶液加入抗坏血酸或Na2SO3后,吸光度值可稳定不变.本文研究提示:黄芩素对光和pH稳定性差;抗坏血酸和Na2SO3具有提高黄芩素溶液稳定性的作用.

| Abstract: | The effects of light,temperature,pH,vitamin C and sodium sulfite on the stability of Baicalein were studied by UV-Vis spectrum.The absorbency intensity of Baicalein at 272nm obviously decreases in 8hr in the condition of keeping the solution at the room-temperature, while acid Baicalein solution can stabilize for 6hr.At the high temperature or in the dark,or in pH 10 the additions of small amounts of vitamin C or sodium sulfite can stabilize the solution. |
