title: [Correlative study on the storage time and quality of rhizoma Dryopteris crassirhizomae].
abstract: The contents of dryocrassin in Rhizoma Dryopteris Crassirhizomae were determined by TLC-scanning in a period of two years of storage. Phloroglucinol content was calculated by area normalization method. The results show that in contrast with the fresh crude drugs of Rhizoma Dryopteris Crassirhizomae, the contents of dryocrassin in the crude drugs of one year and two years of storage have reduced by 22% and 27% respectively, and phloroglucinol contents have reduced by 2% and 8% respectively.
