Analysis of Volatile Components in Different Parts of Rubus chingii Hu Based on Headspace Gas Chromatography Ion Mobility Spectrometry
摘要
Abstract
The volatile components in different parts(root,fruit,leaflet,old leaf,tender stem and old stem)of Rubus chingii Hu(R.chingii)were determined by headspace gas chromatography ion mo‑bility spectrometry(HS-GC-IMS).By focusing on the differences of volatile components in six differ‑ent parts of R.chingii,combined with principal component analysis,partial least squares discrimi‑nant analysis and cluster heat map,the differences of volatile components in different parts were stud‑ied.The results showed that a total of 128 volatile components were obtained from six different parts,92 of which were identified,including 23 alcohols,28 aldehydes,13 ketones,and 8 esters,etc.;GC-IMS fingerprints showed that the volatile components in six different parts were similar,but the content difference was obvious.According to VIP>1.2,17 different components such as(E)-2-hexe‑nal-D,methyl acetate and 3-methylbutanol-D were screened out.The differences of volatile compo‑nents in different parts of R.chingii were analyzed,which provided a new method for rapid and accu‑rate identification of volatile components in different parts of R.chingii.关键词
