摘要:

目的:考察何首乌中何首乌色素的稳定性。方法:从传统中药何首乌中提取何首乌色素组分,初步探讨色素的稳定性,包括:光照、温度、pH 值、氧化剂、还原剂、几种常见食品添加剂及部分金属离子对何首乌色素稳定的影响。结论:温度、光照、氧化剂、Na+、Ca2+、Mg2+ 等金属离子对何首乌色素有明显的破坏作用,而还原剂、柠檬酸、蔗糖、苯甲酸钠、Al3+、Cu2+、Zn2+ 等金属离子对何首乌的何首乌色素有一定的保护作用。

关键词: 何首乌, 何首乌色素, 稳定性

Abstract:

Anthraquinone pigments were extracted from Polygonum multiflorum Thunb., a traditional Chinese herb, with absolute ethanol. The factors involved with the stability of the anthraquinones pigments were discussed including light, temperature, pH, oxidants, reducing agents, food additives and metal ions. Obvious damage effects were observed on the anthraquinones pigments by temperature, light, oxidants, and Na+, Ca2+ and Mg2+ metal ions while reducing agent, citric acid, sugar, sodium benzoate, and Al3+, Cu2+ and Zn2+ metal ions exhibited protective effects.

Key words: Polygonum multiflorum Thunb., anthraquinone pigment, stability
