SPME-GCMS Combined AMDIS and KOVATS Retention Index to Analyze the Volatile Organic Compounds in Russula rubra (Krombh.) Bres. Essential Oil

Volatile components in Russula rubra (Krombh.) Bres. were determined with the use of a solid-phase microextraction (SPME)/gas were identified by the automatic mass spectral deconvolution and identification system (AMDIS) and Kovats retention index (RI). Under the optimized conditions of GC-MS, 52 volatile components were identified in Russula rubra, with the relative percentage accounting for 80.2% of the geranyl acetone (11.0%), and 3-octanone (10.7%) were all at higher levels in samples. The main identified compounds were aldehydes, ketones, alcohols, ethers, and alkanes.

Automated summary

Volatile components in Russula rubra were analyzed using SPME/GC-MS, and multiple compounds were identified. Geranyl acetone and 3-octanone were found to be the main components.
