Tu, Xinghao published the artcileEffects of four drying methods on Amomum villosum Lour. ′Guiyan1′ volatile organic compounds analyzed via headspace solid phase microextraction and gas chromatography-mass spectrometry coupled with OPLS-DA, Name: rel-(1R,2R,4R)-1,7,7-Trimethylbicyclo[2.2.1]heptan-2-ol, the main research area is Amomum volatile organic compound drying solid phase microextraction GCMS.
This paper analyzed the effects of four drying methods (heat pump drying, hot air drying, sun drying, and freeze drying) on the volatile organic compounds (VOCs) in fresh Guiyan1 Amomum villosum Lour. Via separation, component differentiation, and overall variance anal. via HS-SPME-GC/MS coupled with OPLS-DA, 133 kinds of VOCs, mainly composed of hydrocarbons, esters, and alcs., were identified. The differences in Guiyan1 processed by freeze-drying and the other three drying methods were the most significant and easily distinguishable. The main VOCs in the dried samples were bornyl acetate and 2-bornanone, with the largest increase in 2-bornanone and the largest decrease in bicyclogermacrene. The obtained data provided guidance for optimizing the processing and storage of Guiyan1.
