Abstract

The contents of 6 secondary metabolites such as tannin , saponin , alkaloid , lignin , emodin and chlorogenic acid in different organs of Rhododendron fortunei different class size were determined .The results showed that there were certain differences among the content of 6 secondary metabolites in different organs of Rhododendron fortunei .The toal content of 6 secondary metabolites was highest in stem .It was 447.5 gkg-1 in middle sized tree , 319.3 gkg-1 in the little tree and 247.5 gkg-1 in young tree , respectively .The total content in the little tree and young tree , took the second place with 256.4 gkg-1 and 207.7 g kg-1 respectively , while it in root was the lowest with 234.8 gkg-1 and 174.7 gkg-1respectively .The total content in the root of the middle-sized tree took the second place 344.5 g kg-1 while that in leaves was the lowest (317.0 g kg-1).The rank of contents of lignin was as follows :stem root leaves .The rank of chlorogenic acid was root leaves stem . The rank of the contents of the other 4 secondary metabolites was leaves stem root while the content of emodin in stem was as much as that in root .In three organs , the total content of 6 secondary metabolites in the middle-sized tree was highest , that in little tree took the secondary place while that in young tree was the lowest .In different organs , there were also certain differences among the contents of 6 secondary metabolites in Rhododendron fortunei with different sizes .[ Ch , 2 tab .18 ref .]
