用毛细管气相色谱法和色谱—质谱联用法对6种酸橙叶精油化学成分进行了分析,其(?)定出44种成分。有5种酸橙叶精油的化学组成几乎相同,它们的主要成分都是芒樟醇(33.91～39.75%)、乙酸芳樟酯(24.18～30.24%)和α—松油醇(8.58～10.39%);其余组分和含量也大致相同。另一种酸橙—枸头酸橙叶精油化学组成与上述5种相差很大:它的主要成分是β—蒎烯(25.99%)。芳樟醇和α—松油醇的含量分别只有10.70%和0.85%,且不含乙酸芳樟酯。这说明枸头橙不是一种真正的酸橙,其植物学地位有待进一步研究。
The chemical compositions of the essential oils of six lime leaves were analyzed by capillary gas chromatography and chromatography-mass spectrometry, and 44 components were determined by (?). The chemical composition of the five essential oils of Lime leaf was almost the same. Their main components were mannitol (33.91 to 39.75%), linalyl acetate (24.18 to 30.24%), and alpha-terpineol (8.58 to 10.39%). ); The remaining components and content are also about the same. The chemical composition of the other lime-Shantou Lime leaf essential oil is quite different from the above-mentioned five species: its main component is β-pinene (25.99%). The contents of linalool and α-terpineol were only 10.70% and 0.85%, respectively, and did not contain linalyl acetate. This shows that taro orange is not a real lime, its botany status needs further study.
