Abstract:
Through the records of herbal and market investigations,the samples collected from different market and origin were analyzed,and the appearance character indexes were determined in order to revise the commodity specification and grade standard of Dipsaci Radix combined with production practice. This is also to analyze association of the appearance with quality different of intrinsic components. The investigation results indicated the root's long and thick was better,and atrovirens of fracture surface,there are most of the market is dominated by the ungraded goods. Through principal component analysis,variance analysis and cluster analysis,combining with the feasibility of actual operation and herbal record,the length,middle diameter and phloem color were filtrated and the specification was divided into 2 ranks: the selection and ungraded goods,and the grade was divided into 2 ranks for the selection goods: big,small selected goods. Moreover,there were no significant correlation between the appearance and the intrinsic quality index of Dipsaci Radix,the content of extractum were significantly positive correlation with the moisture,but had extremely negative correlation with the total ash. Multiple comparisons indicated that the content of the moisture,extractum and asperosaponin VI of the selected goods were higher than the ungraded goods,while the total ash content were lower,and they hasn't significant difference. The commodity specification and grade standard of Dipsaci Radix as a basis provide commodity specification and grade standard of communities and standardizing market trade order.
