庙宇产川党参挥发油稳定性的研究

The Stability of the Essential Oil from Codonopsis tangshen Oliv.

用水蒸气蒸馏法提取庙宇产川党参挥发油,探讨温度、超声波、pH值和金属离子对庙宇产川党参挥发油稳定性的影响.结果表明:庙宇产川党参挥发油在低温(4℃)保存下较为稳定;超声波和pH值对庙宇产川党参挥发油的稳定性影响较大;另外,K+,Na+,Ba2+,Mg2+,Al 3+,Ca2+对庙宇产川党参挥发油的稳定性均有不同程度的影响,其中Mg2+,Al 3+,Ca2+对庙宇产川党参挥发油的稳定性影响较大.为保证庙宇产川党参挥发油的品质,应在低温条件下保存,同时应避免与超声波、酸碱以及Mg2+,Al 3+,Ca2+接触.

Steam distillation was used to extract the essential oil of Codonopsis tangshen Oliv. , and the effects of temperature, pH, ultrasonic wave and metal ions on its stability were investigated. The results indicated that it was better to store the essential oil at a relatively low temperature （4℃）, that ultrasonic wave and pH value had some impact on the stability of the essential oil, and that the presence of K^＋ , Na^＋ , Ba^2＋ , Mg^2＋ , Al^3＋ and Ca^2＋ , especially Mg^2＋ , Al^3＋ and Ca^2＋ , affected the stability of the essential oil. Therefore, to guarantee the quality of the essential oil of C. tangshen, it should be preserved at a low temperature, and its contact with ultrasonic wave, acid or alkali, and Mg^2＋ , Al^3＋ or Ca^2＋ should be avoided.
