STUDY ON THE COMPOSITION OF ESSENTIAL OIL FROM FLOWER BUD AND BUD OF SOPHORA JAPONICA L. IN HOABINH AND HUNGYEN PROVINCES

Abstract

In this study we reported identified compounds of the essential oil from the fresh bud and the flower of Sophora Japonica L. cultivated in Vietnam analyzing by GC-MS. The major components were caryophyllene, α-humulene, (-)-caryophyllene oxide, 8-heptadecene, phytol and tricosane which were detected in both flower oil and bud oil. The results also showed that these oils were poor in monoterpenes. The major groups of the essential oil of bud and flower were found to be sesquiterpenes (11.45%, 56.69%), oxygenated sesquiterpenes (8.47%, 21.05%) and oxygenated diterpenes (15.62%, 5.72%), respectively. Moreover, the changing of the composition of flower oil and bud oil both from Hoabinh and Hungyen provinces was shown
