복분자(Rubus coreanus Miquel) 와인의 ethyl acetate 획분으로부터 저분자 휘발성 화합물들의 분리 및 구조해석
Isolation and Identification of Low Molecular Volatile Compounds from Ethyl Acetate Layer of Korean Black Raspberry (Rubus coreanus Miq.) Wine
In the course of our investigation for chemical constituents in the ethyl acetate layer of Korean black raspberry wine, five compounds were isolated and purified by silica gel column chromatography and high-performance liquid chromatography. The isolated compounds were identified as ethyl succinate (1), vanillic acid (2), ethyl 3,4-dihydroxybenzoate (3), furan-2-ol (4), and 4-(4-hydroxyphenyl)butan-2(S)-ol (5) based on the spectroscopic data of electrospray ionization tandem mass spectrometry and nuclear magnetic resonance. The presence of 2 in Korean black raspberry has previously reported. However, 1 and 3-5 in Korean black raspberry and its wine were isolated for the first time.
