Abstract:

To provide a theoretical basis for the resource utilization of Chinese chestnut,the mature leaves of four chestnut cultivars were tested using ultra high performance liquid chromatography-tandem mass spectrometric,and functional secondary metabolites were screened by consulting relevant pharmacopoeias and searching the Chemical Book,Chemsrc,pharmacopeias and Web of Science database. The contents of 18 secondary metabolites we focused on in different cultivars were compared and analyzed. The study showed that a total of 673 kinds of secondary metabolites were detected in chestnut leaves,including flavonoids,phenolic acids,alkaloids,tannins,terpenoids,lignin and coumarin. Principal component analysis and cluster analysis showed that the difference of secondary metabolomics profile between Yanshanzaofeng and Yankui was little. The major secondary metabolites contributing to the classification were phloretin,didymin,salirepin,arbutin,cinnamic acid,gallocatechin,procyanidin B1 and so on. The differential metabolites could also be used as biomarkers to distinguish different chestnut varieties. A total of 202 functional secondary metabolites were selected,including 51 phenolic acids,24 alkaloids,83 flavonoids,21 terpenoids,14 lignins and coumarins,and 9 tannins. The contents of active substances were high in leaves such as protocatechuic acid,maslinic acid,ursolic acid,ellagic acid,chlorogenic acid,avicularin,kaempferol-7-O-glucoside,quercetin,spiraeoside,astragalin,betanin,tiliroside,ditymin and baimaside,which provided reference for the resource utilization of Chinese chestnut leaves.

Key words: Chinese chestnut, Leaf, Secondary metabolite, Functional substance
