摘要
以中华芦荟、库拉索芦荟和木立芦荟为试验材料,采用HPLC技术,研究了增强UV-B辐射对3种芦荟叶片中主要药用成分总蒽醌、芦荟素和芦荟大黄素含量的影响。结果显示:增强UV-B辐射20 d,每天处理6 h,库拉索芦荟和木立芦荟叶中总蒽醌、芦荟素、芦荟大黄素的含量增加,叶提取物中出峰数量增多,总峰面积增大;而中华芦荟中蒽醌类物质含量显著降低,叶提取物中出峰数量减少,总峰面积减少。研究表明,增强UV-B辐射能刺激库拉索芦荟和木立芦荟叶片中蒽醌类物质的积累和新物质的合成,而不利于中华芦荟蒽醌类物质的积累。
Effects of enhanced UV-B radiation on anthraquinones,aloin and aloe-emondin contents of 3 species of Aloe were studied by High Performance Liquid Chromatography（HPLC）.The results indicated that twenty days of enhanced UV-B radiation（daily 6 h） could increase total anthraquinone,aloin,aloe-emodin contents in Aloe barbadensis and Aloe arborescens leaves.In addition,the number of peaks,the total peak area increased in A.barbadensis and A.arborescens leaf extracts.However,the total anthraquinone,aloin,aloe-emodin contents,the number of peaks,the total peak area lowered significantly under the UV-B radiation in Aloe vera var.chinensis.This result shows that the accumulation of anthraquinone in A.barbadensis and A.arborescens leaves can be promoted by UV-B radiation but not conducive to A.vera var.chinensis.
