Volatile Components Analysis of Begonia Floral Aroma
摘要
Abstract
In order to understand the differences of volatile components among different Begonia species,the volatile components from male flowers of Begonia kui,B.ornithophylla and B.barsalouxiae were determined and analyzed by headspace solid-phase microextraction-gas chromatography-mass spectrometry.The results showed that 97 volatile components were identified from three kinds of Begonia flowers,among which 30 were from B.kui,mainly heterocyclic compounds,did 56 and 44 from B.ornithophylla and B.barsalouxiae,respectively,most of them were alcohols.Principal component analysis(PCA)showed that there are obvious differences in the main aroma components of three Begonias.There were 15 key floral components screened out by partial least square discriminant analysis(PLS-DA),it was inferred that the aromas of B.kui were wax and balm type,that of B.ornithophylla were citrus type,and that of B.barsalouxiae were floral type.Therefore,the types and contents of main volatile components and main aroma substances of different Begonias species had great differences.Floral fragrances were formed by the interaction of various volatiles,and the aroma type is determined by the volatiles with a higher odor value.关键词
