采用直接进样电喷雾电离质谱仪(ESI-MS)对番荔枝果肉、果皮和番荔枝种子乙醇提取物的极性成分进行了研究。提取液获得了含有多种诊断离子的特征ESI质谱图，为快速、可靠地提供信息提供了依据。该技术提供的成分结构信息揭示了被广泛报道为有效抗氧化剂的重要生物活性成分的存在，如抗坏血酸、咖啡酸、奎宁酸、阿魏酸、黄木素、芦丁、咖啡酰酒石酸、咖啡酰葡萄糖和[栎素+己糖+戊糖]−H]−1这是首次报道具有良好抗氧化活性的花生果皮和种子乙醇提取物的组成。
The polar components of Annona crassiflora pulp, peel and seeds ethanolic extracts were investigated by direct infusion electrospray ionization mass spectrometry (ESI-MS) both in the negative ion mode. Characteristic ESI mass spectra with many diagnostic ions were obtained for the extracts, serving for fast and reliable information. The technique provided information of component structures revealing the presence of important bioactive components widely reported as potent antioxidants such as ascorbic acid, caffeic acid, quinic acid, ferulic acid, xanthoxylin, rutin, caffeoyltartaric acid, caffeoyl glucose and [quercetin+hexose+pentose−H]−1This is the first report on the composition by ESI-MS of araticum peel and seed ethanolic extracts demonstrating excellent antioxidant activity.
