绵马贯众贮存时间与药材质量相关性研究

Correlative Study on Storage Time and Quality of Rhizoma Dryopteris Crassirhizomae

用薄层扫描法测定绵马贯众在２年贮存期中东北贯众素的含量；用面积归一法计算总间苯三酚衍生物的含量。结果提示以绵马贯众鲜品为对照，贮存１年和２年的贯众药材东北贯众素的含量分别降低了２２％和２７％，总间苯三酚衍生物含量分别降低了２％和８％。

The contents of dryocrassin in Rhizoma Dryopteris Crassirhizomae were determined by TLC-scanningin a period of two years of storage. Phloroglucinol content was calculated by area normalization methed. The resultsshow that in contrast with the fresh crude drugs of Rhizoma Dryopteris Crassirhizomae,the contents of dryocrassin inthe crude drugs of one year and two years of storage have reduced by 22% and 27% respectively, and phloroglucinolcontents have reduced by 2% and 8% respectively.
