Development of bioactive components from Chaenomeles sinensis leaves

Abstract

Due to its good ornamental value, Chaenomeles sinensis has a long history of planting in China, and its fruit has health efficacy. The components from fruit and the functions of them have been fully excavated and developed, but there is little research on Chaenomeles sinensis leaves. In our study, the components of Chaenomeles sinensis leaves were extracted by ethanol and acetone. The extracts were identified by FT-IR and GC-MS in order to detect and excavate the bioactive components. The result shows that Chaenomeles sinensis leaves contain alcohols, ethers, aldehydes and other substances which were identified by FT-IR. The main volatile organic compounds (VOC) of Chaenomeles sinensis immature leaves are alcohols, ketones, alkenes and alkanes. Some substances can be simultaneously extracted by two solvents. Ethanol extracts contain high content of biogenic substances, and acetone solvents can effectively extract bioenergy substances.
