Valeriana amurensis Smirn. ex Kom. is an herb species. The volatility of the species is effectual for insomnia and neurasthenic. The study focused on the natural populations of Valeriana amurensis, which distributed in Wuma Nature Reserve (Inner Mongolian), Liangshui National Nature Reserve (Less Xing'an Mountains) and Xiangyang Forest Farm (Wuchang County). The population properties in different communities, the physiological ecological characters of seed dormancy and germination, the cultivation technique, and the chemical composition in root of Valeriana amurensis were researched. The results of the research could provide theory and technique supports in cultivation and GAP standard.27 field plots of 9 communities were sampled in study area. The result of correlative analysis showed, the importance values of Valeriana amurensis reached 49.9% and 49.1% in Ass. Rhytidiadelphus triquetrus, Abies nephrolepis and Ass. Calamagrostis angustifolia, Carex schmidti. The mentioned associations provided the most suitable habitat for Valeriana amurensis.The research results of the seed dormancy showed, the seeds of Valeriana amurensis reached highest germination rate (82%) at the temperature treatment in alteration of 10℃ and 25℃, and soil was fertile sandy. The seed soaking liquid, water extrac, ethanol extrac had negative influences for the seed germination.The cultivation results showed, the best sowing date of Valeriana amurensis was on 15th May in Wuchang County, the most suitable environmental temperature should be 20℃- 27℃, and the optimal seedling density was 83 /m~2. The transplant of seedling should be processed after the upgrowth of leaves and root.By using the GC-MS, the chemical composition in root of Valeriana amurensis was analyzed. The avilid components in root of different provenance were similar, and the contents of effective composition in roots were depended on the provenance. Meanwhile, P-Panasinsene was founded in root of Valeriana amurensis for the first time.
