摘要:

使用锦葵色素-丙酮酸混合溶液作为反应液合成锦葵色素衍生花色苷——Vitisin A,研究Vitisin A的高效液相色谱检测方法,并优化检测条件。初步研究了Vitisin A合成过程中量的变化情况。结果表明,利用反相高效液相色谱法,采用CAPCELL PAK C18 ACR色谱柱,乙腈-水(磷酸调pH值为1.5)溶液作为流动相,使用紫外检测器在波长为507 nm条件下对Vitisin A进行检测。使用质谱法对Vitisin A进行定性分析,将结果与谱库信息进行对比。该方法同样适用于检测葡萄酒中的Vitisin A。

Abstract:

This study aimed to develop an HPLC method for detecting vitisin A in red grape wine under optimized
testing conditions. Malvidin-pyruvate mixed solution was used as the reaction liquid to synthesize vitisin A derived from
malvidin. The preliminary study demonstrated the quantitative changes of vitisin A during the synthesis process. The
optimal chromatographic conditions for vitisin A separation were determined by using a CAPCELL PAK C18 ACR acidproof
column with acetonitrile-water (adjusted to pH 1.5 with phosphoric acid) as the mobile phase, and the UV detector
wavelength was set at 507 nm. Mass spectrometry was used to conduct the qualitative analysis of vitisin A, and the results
were compared with those from the mass spectral library. The method is suitable for detecting both synthetic and natural
vitisin A in red grape wine.

Key words: vitisin A, malvidin, grape wine, high performance liquid chromatography-mass spectrometry-mass spectrometry (HPLC-MS-MS)
