[Investigation Report of Tripterygium wilfordii and Tripterygium hypoglaucum].

OBJECTIVE

To get the information of resources, cultivation, commodity circulation and other aspects of Tripterygium wilfordii and Tripterygium hypoglaucum.

METHODS

Collect samples in 13 locations of Tripterygium wilfordii and Tripterygium hypoglaucum, compare their plant morphological characteristics and growth habit, and investigate their wild resources conditions, planting information, easy-confused varieties and different commodity features.

RESULTS

(1) Tripterygium wilfordii and Tripterygium hypoglaucum were mainly collected under woods or on the edge of woods,and light and moisture attributed to their distribution to some extent. (2) Wild resources of Tripterygium wilfordii and Tripterygium hypoglaucum were shrinking, and both of their cultivation history were relatively short and their cultivation technique were still in a low level. (3) Due to lack of harvesting and processing standards, decoction pieces, varying from roots, rhizomes to stems of plants, were all sold as commercial medicines.

CONCLUSION

Wild resources of Tripterygium wilfordii and Tripterygium hypoglaucum are shrinking,and the standardized research on cultivation-harvest processing and commercial medicines remains to be further carried out.
