Abstract:

Steam distillation extraction followed by GC-MS combined with quantification by peak area normalization method was used to analyze volatile compounds in the fruitbodies of Tricholoma matsutake Sing.. Meanwhile, the relationship between volatile compounds and characteristic aroma of the fruitbodies of Tricholoma matsutake Sing. was explored. Results showed that 46 compounds were identified, accounting for 91.76% of the total volatile compounds from the fruitbodies of Tricholoma matsutake Sing. among which the predominant compounds were hexanoic acid (11.04%), bornyl acetate (11.28%) and methyl cinnamylate (27.37%). Bornyl acetate and methyl cinnamylate were mainly responsible for the characteristic aroma of the fruitbodies of Tricholoma matsutake Sing..

Key words: Tricholoma matsutake Sing., volatile oil, gas chromatography-mass spectrometry (GC-MS)
