Ichang lemon is a citrus fruit whose rind gives off a delicious and much appreciated fragrance and flavor. The volatile components of the fruit peel of Ichang lemon were investigated by GC-MS and GC-O (AEDA method). Simultaneously, its genetic origin was identified by using diagnostic SNP markers specific to ancestral species and multiallelic SSR and InDel markers. Ichang lemon combines three ancestral genomes (, , and ) and may be a pummelo × Yuzu hybrid. Although the major compounds of the Ichang lemon aromatic profile were present in , a few pummelo-specific compounds were also detected, such as indole and nootkatone, in agreement with its maternal lineage. 3-Methyl-3-sulfanylbutyl acetate, reported to occur in passion fruit and brewed coffee, was identified by GC-MS, GC-QTOF-MS, and GC-FTIR for the first time in citrus. This odor-active compound has a sulfurous, tropical fruity, green note.
宜昌橙是一种柑橘类水果，其果皮散发出美味且备受赞赏的香气和风味。采用气相色谱 - 质谱联用（GC - MS）和气相色谱 - 嗅闻（GC - O，香气提取物稀释分析方法）对宜昌橙果皮的挥发性成分进行了研究。同时，利用特定于祖先物种的诊断性单核苷酸多态性（SNP）标记以及多等位基因简单重复序列（SSR）和插入缺失（InDel）标记确定了其遗传起源。宜昌橙结合了三个祖先基因组（、和），可能是柚与枸橼的杂交种。尽管宜昌橙香气特征的主要成分在中也有，但也检测到了一些柚特有的化合物，如吲哚和诺卡酮，这与其母系谱系一致。乙酸3 - 甲基 - 3 - 硫代丁酯，据报道存在于西番莲果和煮咖啡中，首次通过气相色谱 - 质谱联用（GC - MS）、气相色谱 - 四极杆飞行时间质谱联用（GC - QTOF - MS）和气相色谱 - 傅里叶变换红外光谱联用（GC - FTIR）在柑橘类水果中被鉴定出来。这种气味活性化合物具有硫磺味、热带水果味和青香调。
