| Popis: | To fully analyze the composition of volatile oil extracted from Tremella fuciformis, hydrodistillation (HD) and solid phase microextraction (SPME) were adopted simultaneously. In both cases, the analysis was carried out using gas chromatography-mass spectrometry and the antioxidant activity of the volatile oil was determined by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method with rutin as a positive control. Nineteen components in HD and 68 components in SPME were identified, respectively. Moreover, the oil obtained from T. fuciformis by HD indicated that aromatic compounds were a major class (93.5%), followed by the terpenes (5.7%), alkanes (0.4%), and alcohols (0.3%). Among them, butylated hydroxytoluene was the highest concentration (92.5%) of the compounds. The compounds detected by SPME were different from those of HD, and the substances with the largest content were esters (57.7%), followed by alcohols (19.0%), acids (7.0%), and aldehydes (6.3%). Only three of the same substances were detected in both of them, namely borneol, (-)-α-terpineol, and acetic acid. In the DPPH assays, strong antioxidant activity (IC50 = 0.176 mg/mL) was evident in volatile oil from T. fuciformis. Antioxidant activity was positively correlated with the concentration of volatile oil. |
