According to the analysis by gas chromatography/mass spectrometry, 32 peaks were separated and 21 components were identified. The identified constituents represent 99.58% of the total content. The main components were 1-Pentanol; butanedioic acid, diethyl ester; phenylethyl alcohol; butanedioic acid, hydroxy-, diethyl ester, (+)-; benzeneethanol, 4-hydroxy-; succinoic acid, 2-hydroxy-3-methyl-, diethyl ester; 1-propanol, 3-(methylthio)-; 5-oxotetrahydrofuran-2-carboxylic acid, ethyl ester; 2(3H)-uranone, 5-ethyldihydro-; tartaric acid diethyl ester.
