摘要
目的 :建立植物挥发油提取量与提取时间关系式。方法 :从物质传递速率方程简化得到该关系式ln(Vs-V) =-Kt+A ,K、A为参数。结果 :甘松挥发油的实验得A =0 .44 ,k =2 .7× 10 -3 ,r =- 0 .99;丁香挥发油实验得A =1.33 ,k =3.6 2× 10 -3 ,r =- 0 .99。结论
Objective: To establish the relationship equation of yield and extraction time of plant volatile oil. Methods: By means of the rate eqation of substance transfer, the relationship equation of yleld (v) and extraction time (t) of volatile oil was accomplished: ln(V s-V)=-K t+A,K and A were parameters. Results: The experiment of volatile oil of Rhizoma Nardostachyos indicated that A was 0.44, K was 2.7×10 -3 , and the correlation coefficient (r) was -0.99 whereas A was 1.33, K was 3.62×10 -3 and r was -0.99 in the experiment of volatile oil of Flos Syzygii Aromatici. Conclusion: This relationship equation is able to reflect the relationship between the yield and extraction time of volatile oil.
