ABSTRACT
Objective:
To study the solvent-free microwave extraction for oils of Acori Tatarinowii Rhizoma and analyze the volatile components.Methods:
The paper selected the best technological conditions by L9(34) orthogonal test, with the index of α-asarone, volume of volatile oils, and sum of the percentage, The essential oils in Acori Tatarinowii Rhizoma were analyzed with GC-MS.Results:
The percentage of volatile oils was calculated according to peak area normalization method. The results showed similar amount of volatile oil components by two methods, and the extraction rates of α-asarone, β-asarone, and γ-asarone accounted for 4.12%, 55.11%, and 10.54% on the method of solvent-free microwave extraction, while the steam distillation was 5.39%, 47.03%, and 9.15%. To compare with two methods, solvent-free microwave extraction extracted volatile oil 0.235 mL and α-asarone 31.99 mg for 5 min, while steam distillation extracted volatile oil 0.175 mL and α-asarone 29.09 mg for 1 h. The method of solvent-free microwave extraction had the advantage of short reaction time and high yields.Conclusion:
Solvent-free microwave extraction is a new method with shorter extracting time and better extracting efficiency.
