Effect of Environmental Ecological Factors on Saponins of Medicinal Plant

To analysis the affect on the saponins of the medicinal plants bring by the major environmental factors.We analysis the relationship between the environmental factors and the composition of the saponins of the medicinal plants.the environmental factors,such as origin,harvest time,light,temperature,and cultivation measures etc.analysis the mechanism to find the theoretical basis for these phenomenons.The environmental factors such as origin,harvest season,growth years,light and temperature in the prosess of growth,and the regulate of the fertilizer or water in the prosess of cultivation,all of these have significant impact on the saponin of the medicinal plant.These results have certain theoretical support.The production of high quality of Chinese herbal medicines should consider the suitable area for the cultivation,and to determine the reasonable harvest time.The scientific cultivation practices in the cultivation is the effective means of to improve production and active ingredients of the medicinal plants.It is als a good way to take the appropriate short-term stress during the progress of optimize the cultivation conditions.
