Abstract
β-Sitosterol content in grape of different species, in grape of the same species but of different mature period, and in grape wine were determined by gas chromatography/mass spectrometry (GC-MS). The results suggested that there existed β-Sitosterol in both grape juice and grape seed and β-Sitosterol relative content differed for grape of different mature period. Grape fruits could directly transfer into β-Sitosterol in grape wine and true grape wine could be identified by the existence of β-Sitosterol. (Tran. by YUE Yang)
