Title: Stem and Leaf Secondary Metabolites Content Analysis of Magnolia sieboldii in Laoling Natural Preservation Area
Abstract: Stem and leaf secondary metabolites content of Magnolia Sieboldii in different altitude gradients in Laoling Natural Preservation Area,Hebei Province were determined and analyzed. The results show that in different elevations of the same vegetative organs,leaves and shoots of chlorogenic acid,saponins and tannin content are the highest at an altitude of 1 100 m,while the content of flavonoid is the highest in the leaf at an altitude of 800 m and in the shoot at an altitude of 1 300 m. In the same altitude of different organs,chlorogenic acid and flavonoid content in the leaf are higher than that in the shoot,while that of Tannin is on the contrary. Saponins content has no obvious difference in the leaf and shoot. In different elevations,the total chlorogenic acid contents in the vegetative organs are higher than other three kinds of secondary metabolites,and total saponins are far below the other three kinds of secondary metabolites. These four secondary metabolite contents are the highest at an altitude of 1 100 m,the lowest content total chlorogenic acid,total flavonoid and total tannins are at an altitude of 500 m,the total saponins are the lowest at an altitude of 1 000 m.
