| 香橙果实香味浓郁，但是相关的物质基础并不清楚。采用顶空固相微萃取（HS-SPME）结合气相色谱-质谱联用（gas chromatography-mass spectrometry，GC-MS）技术开展香橙果实的挥发性物质组分检测与鉴定。结果表明，香橙果皮中主要含有61种挥发性物质，其中萜烯类物质33种，总含量82.30%。果皮中含量最高的挥发性物质是柠檬烯（14275.39 ± 1627.08 μg/g FW），占总物质的68%；其次是γ-松油烯（2096.32 ± 235.90 μg/g FW），占总物质的9.99%；芳樟醇（965.64 ± 14.53 μg/g FW），占总物质的4.60%。果肉主要含有47种挥发性物质，其中萜烯类物质27种，占总含量的82.30%。果肉中含量最高的挥发性物质也是柠檬烯（46.50 ± 12.61 μg/g FW），占总物质的65.94%；其次是芳樟醇（6.33 ± 1.48 μg/g FW），占总物质的8.98%；γ-松油烯（4.75 ± 1.27 μg/g FW），占总物质的6.74 %。作为香橙的特征香味物质，(+)-香橙烯在果实的果皮和果肉中的含量分别为136353.16 μg/g FW （0.65%）和 312.27 μg/g FW （0.44%）。 |

| Abstract: Xiangcheng (Citrus junos Sieb. Ex Tanaka) fruit has a strong fragrance whereas its aroma components are not clear yet. Headspace-solid phase micro extraction (HS-SPME) combined with gas chromatography-mass spectrometry (GC-MS) was used to analyze the aroma composition in Xiangcheng fruit. Sixty-one volatile substances were identified in the peel, including thirty-three terpenes that accounted for 82.30% of the total volatiles content. In the peel, D-limonene (14275.39 ± 1627.08 ng/g FW) showed the largest amount accounting for 68% of the total volatile compounds, followed by γ-terpinene (2096.32 ± 235.90 ng/g FW) and linalool (965.64 ± 14.53 ng/g FW) accounting for 9.99% and 4.60%, respectively. In the pulp, forty-seven volatile compounds were annotated, 27 of which were terpenes, with the proportion of 82.30%. The most abundant volatile substance in the pulp was also D-limonene (46.50 ± 12.61 ng/g FW) accounting for 65.94% of the total volatile substance, followed by linalool (6.33 ± 1.48 ng/g FW) accounting for 8.98% and γ-terpinene (4.75 ± 1.27 ng/g FW) with the proportion of 6.74% in the total volatiles. As the characteristic aroma substance of Xiangcheng, the contents of (+)-citrinene in the fruit peel and pulp were 136353.16 ng/g FW (0.65%) and 312.27 ng/g FW (0.44%), respectively. |
