超微粉碎决明子对其大黄酚溶出量的影响

对超微粉碎前后决明子进行大黄酚溶出量的对比研究。结果表明：在相同提取时间的条件下水煎煮决明子药材，大黄酚的提取率只有7．6％，而经不同条件超微粉碎后的各组决明子的提取率分别提高到69．7％、57．1％、32．4％；5min水浸泡下，决明子微粉中总大黄酚含量与药材水煎煮90min的含量相当。粉碎前对样品进行适当干燥可提高总大黄酚的溶出量。

Influence of Semen Cassia by Supermicro-pulverization on Its Dissolved Matter of Chrysophanol

Comparative study of dissolved matter of chrysophanol of semen Cassia and the powder by supermicro|pulverization was made. In same extraction time only 7.6% chrysophanol in semen Cassia was extracted compared with in the groups of supermicro|pulverized powder of semen Cassia in which 69.7%,57.1% and 32.4% chrysophanol were extracted. The amount of dissolved matter of chrysophanol of supermicro|pulverized powder of semen Cassia by 5 minutes immersed in water was same compared with that of crude drug of semen Cassia by 90 minutes decocted. Proper desiccation of sample before supermicro|pulverization could increase dissolved matter of chrysophanol.
