Abstract

Orah mandarin is a new and hybrid fruit. Orah mandarin peel (OMP) and three traditional mandarin peels (TMPs, Chinese "Chenpi") were comparatively analyzed using data-repository-aided ultra-high-performance liquid chromatography-quadrupole-orbitrap-tandem mass spectrometry. The analysis has identified and quantified 52 compounds (including 35 phytophenols). Meanwhile, nine isomers were also distinguished, and 18 "unexpected" compounds were found in mandarin peels for the first time. Hesperidin was found to be the most abundant phytophenol in both OMP and three TMPs. All identified phytophenols were individually evaluated for antioxidant capacities. Their antioxidant percentages were further multiplied by the corresponding chemical contents to calculate the antioxidant contribution (AC) values. Ten phytophenols play a dominant role in AC in the whole peel and show similar distribution in the four peels. Thus, from the angle of antioxidant chemistry, OMP is similar to three TMPs and may serve as a potential functional food similar to Chenpi products (especially Guagnchenpi). Nevertheless, OMP can be recognized by some specific compounds (e.g., isofraxidin and xanthotoxin).

基于超高效液相色谱-四极杆-轨道-质谱分析的陈皮柑皮与陈皮柑皮的比较研究

枸杞是一种新型杂交水果。采用数据存储辅助的超高效液相色谱-四极杆轨道-串联质谱法对Orah柑皮（OMP）和3种传统柑皮（TMPs，中国“陈皮”）进行对比分析。该分析鉴定并量化了52种化合物（包括35种植物酚）。同时，还分离出9种异构体，并首次在柑桔皮中发现18种“意想不到”的化合物。在OMP和三种TMPs中，橙皮苷是含量最高的植物酚。所有鉴定出的植物酚都被单独评价了抗氧化能力。再将它们的抗氧化百分比乘以相应的化学成分，计算出抗氧化贡献（AC）值。10种植物酚在整个果皮中起主导作用，在4种果皮中的分布相似。因此，从抗氧化化学的角度来看，OMP与三种tmp相似，可能成为类似陈皮产品（特别是广陈皮）的潜在功能食品。然而，OMP可以被一些特定的化合物（如异黄菌素和黄毒素）识别。
