Chinese angelica Umbelliferae Angelica dried root of Angelica sinensis (Oliv.) Diels, is commonly used in traditional Chinese medicine in China. Now, however, resource condition and quality control, there are many problems. In this paper, a nationwide field survey, literature and specimen inspection, market research, Chinese angelica resources Medicine source, suitable for planting area, the distribution of resources, the production situation, systematic summary and analysis, found the Angelica mainly cultivated in Gansu, Sichuan , Yunnan, Hubei, Shaanxi, Shanxi, Guizhou, Qinghai, wild resources in Gansu, Sichuan, Shaanxi, Tibet, only a relatively small population distribution. Systematic analysis shows that the basic conditions of Angelica suitable for planting area is an altitude of approximately 1750-3100m, average relative humidity of 65-80%, annual average sunshine hours in length 1380-2650h, the annual average temperature of Road real estate ecological factor approximately 3.3-12.8 ℃, the annual accumulated medicines growing season 1692-3900 ℃, annual precipitation is 500-1250mm. The survey also found that part angelica herbs growing areas in recent years the herbal complex and there are more serious situation early bolting more difficult to be picked in the wild germplasm, breeding work is weak. This article is based on field surveys of a different origin Angelica cultivation techniques and pest control brief, Angelica sinensis According to market research brief market demand analysis. Through the whole process of growth and development from planting seedlings to fruition Min County in Gansu Province, Angelica found Angelica Minxian appropriate to adopt seedling transplanting cultivation methods, the angelica the most optimum harvest period in September, the second year of the growing season mid-harvest period, the seeds of the most suitable is the third year of the growing season in late August. Chinese angelica root fresh weight yield per square meter is about 882 g, and the dry weight of 252g, dry discount rate of about 3.5 per hectare, Angelica reserves is 2520 kg. Found throughout the experiment concluded the wasteland nursery caused environmental degradation of resources, and transplanting seedlings in winter storage is easy to cause early bolting. Meanwhile, Angelica samples collected from the National the Angelica main producing areas and the main distribution area (a total of four provinces and 13 counties) 40 parts, using Supercritical CO2 Fluid Extraction Methods for Extracting Volatile oil supercritical CO2 extraction conditions: pressure 35MPa, temperature 35 ℃, time 120min. GC-MS combined with technical analysis different habitats angelica volatile oil components, and (Z) - ligustilide and positive butylidene phthalide quantitative analysis, clear quality characteristics of the major producing areas of Angelica sinensis, analysis and evaluation of the quality of different Radix innovative research results. Comprehensive analysis shows that the test Gansu Province Zhangxian Angelica has obvious advantages, its best quality; The Angelica MINXIAN dominant morphology, commodity type and number of compounds, as traditional authentic ingredients quantities of better; Zhanyi County Angelica indicators ingredients, and the short planting years, so it is worth developing applications. In addition, Gansu Province, the Diebu wild angelica there are obvious advantages in the number of compounds and indicators on the ingredients, and to maintain the genetic diversity of Angelica, but wild resources endangered urgent need to strengthen the protection of wild resources.
