摘要 目的:研究决明子在炮制前后化学成分的整体变化,寻求炮制增效的物质基础,揭示炮制机理。方法:取决明子生品和炮制品,分别用甲醇和水提取,将提取液进行高效液相色谱分析。比较决明子生品和炒制品醇提液和水提液的色谱图。结果:决明子炒制品醇提液中,有1种原有成分消失,产生了2种新成分,同时有1种成分含量显著下降,有1种成分含量显著上升;决明子炒制品水煎液中,产生了3种新的成分,同时有3种物质的含量显著下降,有2种物质含量显著上升。在醇提液和水提液中都有同一种新成分产生。结论:决明子炮制后缓和药物性能,增强疗效的物质基础很可能是药性猛烈的成分(蒽醌类)被部分破坏,含量减少或转变成了新的成分,因而缓和药性;同时炒制更利于一些成分溶出,其含量增加而致疗效增强。
