摘 要: 选用水蒸气蒸馏法提取椪柑皮中的香精油,并对椪柑皮精油的稳定性进行了初步研究.通过紫外分光光度法对精油于208nm处吸光值的测定,研究光照、温度变化及不同金属离子对椪柑精油稳定性的影响大小.研究结果显示,光照、温度均影响精油的稳定性,Na+、Al3+在低浓度范围内对精油的稳定性影响不明显,Fe3+对椪柑精油的稳定性影响较大. Perfume essential oil was extracted from essential oil from ponkan peels was subjected to ponkan peels by steam distillation. The stability of the perfume spectral scanning in the wavelength of 208nm in this paper. The influences of illumination, temperature, and different metal ions on the stability of the essential oil were investigated. The results show that the illumination and temperature affect the stability of the essential oil from ponkan peels in different degree. The presence of Na+, AP+ affected the stability of essential oil was not obvious at a low concentration range. But Fe3+ have severe effect at varying concentration range.
