Relationship between Ephedrine Contents and Growth Environment of Herba Ephedrae
摘要
Abstract
Objective:To study the relationship between ephedrine contents in traditional Chinese medicine the dried aerial parts of Ephedra intermedia Schrenk et C .A.Mey.and its growing environment .Methods:Sam-ples of the herb and the soil at its growing site were collected from 14 selected geographic regions .Reference literatures were reviewed and on -the -spot investigation was conducted to understand the growth environ-ment.RP-HPLC was performed to determine the ephedrine contents in the herb .Results:Different regions had different environmental conditions , including the climate , soil, vegetation etc .The contents of ephedrine in the herb varied greatly .The herb produced in eastern and middle southern regions , where the soil was alka-line, had higher content of ephedrine than that produced in northern and far southern regions , where the soil was acidic .Conclusion:The contents of organic matters , effective phosphorus , quick-acting potassium , and the pH value of the soil at the growing site are the factors that correlates with the ephedrine contents in the herb, among which the pH value of soil is the most important positive correlative factor .The alkaline soils in eastern and middle southern benefit the accumulation of ephedrine more than the acidic soils in northern and far southern regions .Other possible factors affecting the ephedrine contents in Herba Ephedrae are the climate factors ( sunshine duration ) .关键词
