Determination of Aroma Composition of Santalum album linn by Solid-phase Microextraction-Gas Chromatography-Mass Spectrometry

Abstract

[Objectives] This study aimed to determine the volatile components in Santalum album linn and gradually clarify the aroma composition of S. album linn. [Methods] Solid-phase microextraction method was used to obtain the volatile components of S. album linn. The aroma components were analyzed by gas chromatography-mass spectrometry and their relative contents were calculated using the area normalization method. [Results] In a dry state at room temperature, 39 chemical components were identified from S. album linn, mainly olefins (91.15%), alkanes (3.00%), alcohols (2.56%), esters (2.19%), ketones (0.55%), aldehydes (0.41%) and heterocyclics (0.14%). [Conclusions] This method has the advantages of low sample consumption, easy operation, rapid identification of aroma components and high sensitivity, and can effectively separate and determine volatile components in S. album linn, realizing the rapid identification of different S. album linn varieties and providing technical support for further research on Chinese medicinal materials.
