摘要:

研究了瓜蒌皮色素的提取方法及其理化性质。结果表明:乙醇- 乙醚(1:1,V/V)的提取效率最高,瓜蒌皮质量与提取液的料液比为1:15g/ml 为宜。光谱特性与稳定性实验结果表明,瓜蒌皮色素在pH2~5 稳定;加热温度低于60℃时,具一定热稳定性;有光照情况下降解加快;Fe3+ 对瓜蒌皮色素的不良影响大于Zn2+、Ca2+;高浓度蔗糖、葡萄糖对该色素有一定保护作用。

Abstract:

It was found experimentally that when the ratios of ethanol to ether and Trichosanthes kirilowii Maxim. peel to ethanol-ether are 1:1 (V/V) and 1:15 (g/ml) respectively, the extraction efficiency of Trichosanthes Kirilcwii Maxim. peel pigment reaches the highest. The spectrum analysis indicated that Trichosanthes kirilowii Maxim peel. pigment is stable at pH 2 to 5 and below 60 ℃, and high concentrations of sucrose and glucose can protect its color. However, Fe3+ has more negative effects on the pigment than Zn2+ and Ca2+, and its degradation may be accelerated under sunlight.

Key words: Trichosanthes kirilowii Maxim., pigment, extraction, physicochemical property
