Comparison of Three Different Extraction Methods for the Determination of the Quality of the Leaf Volatile Oils of Delonix regia (Bojer ex Hook.Raf)

Abstract

13D. regia wood ash induced up to 78, 81 and 89% reduction in the mycelial growth of Helminthosporium sativum, Curvularia lunata and Fusarium graminearum respectively. 12 There is very little research report on the volatile components of the volatile oil of D. regia and no previous report on the effect of extraction methods. It is on this premise that this research seeks to study the effect of three different extraction methods (hydrodistillation, steam distillation and cold maceration) on the yield, chemical composition and quality of D. regia volatile oils.
