Abstract

Abstract:

To objectively evaluate germplasm resources of Litsea coreana in Chongqing,morphological indexes of 123 germplasm resources were investigated. 27 germplasm resources were selected to determine the water extract, tea phoyphenol, total flavonoid, free amino acid and soluble sugar contents.The ranking of biochemical indexes assessment for different germplasm resources was determined by grade and factor evaluating methods. Among these germplasm resources, the average content of water extract was 29.25%, while the maximum was 37.10% (WX18) and the minimum was 22.60%(WL32). The average content of tea phoyphenol was 11.25%, while the maximum was 14.07%(WX4) and the minimum was 9.87%(NC2). The average content of total flavonoid was 1.65%, while the maximum was 2.66%(WX22) and the minimum was 1.03%(NC9).The average content of free amino acid was 0.98%, while the maximum was 1.40%(WX12) and the minimum was 0.73%(WX22). The average content of soluble sugar was 4.73%, while the maximum was 6.35%(WX18) and the minimum was 3.06%(WL30).There were differences in contents of water extract, tea phoyphenol, total flavonoid, free amino acid and soluble sugar among the fresh leaves from different Litsea coreana germplasm resources. These biochemical indexes could be used as indicators for the preliminary evaluation of the germplasm resources.WX18, WX22, WX20, WL40 and WX21 were the top 5 in overall ranking,they were considered as elite germplasm resources.WX18 and WX22 could be used as red-purple bud germplasm resources, WX20 and WX21 could be used as pink bud germplasm resources, and WL40 could be used as new yellow-green bud germplasm.

Key words: Litsea coreana, germplasm, biochemical components, factor evaluation
