Identification of the Volatile Components of Cajanus cajan Roots by Using the Headspace Extraction-Gas Chromatography-Mass Spectrometry
摘要
Abstract
Studying the volatile components of Cajanus cajan roots,and analyzing the biological function of the volatile components of Cajanus cajan roots,can provide scientific basis for the development and utilization of the volatile components of Cajanus cajan roots.The volatile components of Cajanus cajan roots extracted by the steam distillation were detected by using the headspace-gas chromatography-mass spectrometry method.The results indicated that:a total of 98 volatile components were identified from the roots of Cajanus cajan,including 10 components such as alcohols,esters,aldehydes,ketones,acids,terpenes,alkanes,aromatics and alkaloids.Among them,the number of terpenes was the highest,reaching 47,and the relative content was also the highest,reaching 77.863%.The volatile components with higher relative content in Cajanus cajan roots were 10s,11s-himachala-3(12),4-diene,(+)-β-himachalene,di-epi-α-cedrene,α-himachalene,cis-(-)-2,4a,5,6,9a-hexahydro-3,5,5,9-tetramethyl(1H)benzocycloheptene,whose relative contents were 11.377%,10.289%,7.564%,5.834%,and 5.804%,respectively.The study showed that the volatile components of Cajanus cajan roots played an important role in resisting the infestation of pathogens and pests and inhibiting the weeds.关键词
