摘要:

建立进口西拉葡萄酒的高效液相色谱-二极管-离子阱质谱指纹图谱分析方法。样品采用乙酸乙酯萃取,旋转蒸发仪浓缩,甲醇溶解,高效液相色谱-离子阱质谱分析测定。色谱柱采用MG Ⅱ C18柱(150 mm×2.0 mm,5 μm),以pH 3.0水-乙腈为流动相,梯度洗脱,流速0.25 mL/min,多波长检测,离子阱质谱采用负离子模式,扫描范围m/z 50~1 200,可对没食子酸等11 个组分进行定性和定量。维拉西拉葡萄酒的15 个共有峰在60 min内得到良好分离,通过与标准品比较,对其中6 个峰进行了确证,10 批次维拉西拉葡萄酒的相似度均大于0.9。方法简便、灵敏、稳定、精确,生成的葡萄酒指纹图谱能够用于进口西拉葡萄酒的质量评价。

Abstract:

A chromatographic fingerprint analysis method for Australian Virgara Shiraz wine was established by high
performance liquid chromatography-diode array detector-ion trap mass spectrometry (HPLC-DAD-MS). Samples were
extracted with acetic ether, concentrated with a rotary evaporator, and re-dissolved with methanol. HPLC-MS separation was
performed on a MG Ⅱ C18 column (150 mm × 2.0 mm, 5 μm) by gradient elution using a mobile phase composed of water
and acetonitrile adjusted to pH 3.0 at a flow rate of 0.25 mL/min, and multi-wavelength detection was used. The ion trap
mass spectrometry was operated in the positive ion mode with scan range m/z 50 to 1 200 for qualitative and quantitative
analysis of gallic acid and 11 other compounds. A good separation of 15 common peaks of Virgara Shiraz wine was achieved
within 60 min, and 6 of them were confirmed by comparison with reference substances, and the similarity among 10 batches
of Virgara Shiraz wines was all higher than 0.9. The developed fingerprint method is simple, sensitive, stable, accurate, and
suitable for the quality evaluation of Virgara Shiraz wine.

Key words: high perfomance liquid chromatography-diode array detector-ion trap mass spectromtry (HPLC-DAD-MS);chromatographic fingerprint, similarity, import wine, quality evaluation
