摘　　要：采用反相高效液相色谱技术,测定分析新疆玛纳斯55种酿酒葡萄品种中6种有机酸含量。结果表明:酿酒葡萄中的主要有机酸是酒石酸、苹果酸和柠檬酸(相对许多产区含量较高),草酸、琥珀酸和乳酸含量较少;酿酒白葡萄中有机酸总量显著高于酿酒红葡萄,除苹果酸在酿酒红葡萄中的含量高于白葡萄以外,其他5种有机酸在酿酒红葡萄中的含量均较低。不同酿酒葡萄间有机酸含量变化较大;28种酿酒白葡萄中,白比诺(Pinot Blanc)中总有机酸(21.580g/L)、酒石酸(11.790g/L)和苹果酸(9.630g/L)含量最高,白雷司令(White Riesling)中柠檬酸高达5.400g/L,而伏罗西(ВлощVioshi)中总有机酸和苹果酸含量最低(分别为7.250g/L和0)。27个酿酒红葡萄中,以巴柯(Bacco nion)的总有机酸和苹果酸含量(分别为22.27g/L和18.210g/L)最高,而酒石酸含量(2.060g/L)最低,黑后(Heihou)柠檬酸含量(2.510g/L)最高,玫瑰香(Muscat Hamburg)中总有机酸含量(4.94g/L)最低。Six organic acids including tartaric, malic, citric, oxalic, succinic and lactic acids in wine grape from 55 cultivars （including 28 white grape cultivars and 27 red ones） were determined by reversed-phase high performance liquid chromatography （RP-HPLC）. The results showed that tartaric, malic and citric acids were major organic acids in wine grapes. The contents of oxalic, succinic and lactic acids were too low to be detected. The total content of six organic acids in white wine grapes were significantly higher than in red ones. The content of malic acid in red grape cultivars was higher than in white ones, while the five other organic acids were lower in red grape cultivars. Among the 28 white grape cultivars, the highest contents of total acids （21.580 g/L）, tartaric acid （11.790 g/L） and malic acid （9.630 g/L） were detected in Pinot Blanc and higher critic acid （5.400 g/L） was detected in White Riesling, while the lowest contents of total organic acid （7.250 g/L） and malic acid （0 g/L） were detected in BJiom Vioshi. Among the 27 red wine grape cultivars, Bacco nion had both the highest contents of total organic acid and malic acid （22.27 g/L and 18.210 g/L, respectively） and the lowest tartaric acid content （2.060 g/L）; Heihou exhibited the highest content of citric acid （2.510 g/L）, whereas Muscat Hamburg showed the lowest content of total organic （4.94 g/L）.
