摘要
对不同葡萄品种、同一葡萄品种不同成熟期及葡萄酒的β-谷甾醇进行气相色谱-质谱测定。结果表明,在酿酒葡萄的葡萄汁中以及葡萄籽中都存在β-谷甾醇,且在不同成熟期的果实中β-谷甾醇的相对含量不同。葡萄酒中的β-谷甾醇是由葡萄果实直接转化而来的,可根据β-谷甾醇的存在来鉴别真假葡萄酒。(孙悟)
β-Sitosterol content in grape ofdifferem 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 gape 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）
