Abstract:
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.
