Study on the Constituents of Essential Oils of Flower from Elsholtzia stauntonii Benth

OBJECTIVE To study the chemical constituents of essential oils of flower from Elsholtzia stauntonii Benth．METHODS The chemical constituents of essential oils were identified and analyzed by GC/MS and area normalization method. RESULTS Thirty-six compounds were isolated and identified. These compounds concluded 4-(1-methyl ethyl)- benzenemethanol(48.32%), 2-methyl-5-pentanone(3)-furane (22.87%), 2-methyl-5-iso-pentanone-furane (6.40%), β-caryophyllene (3.00%), 2-ethyl-5-iso-butanone-furane(3.56%), caryophyllene oxide (3.46%) and so on. CONCLUSION These compounds were found from the flower of the plant for the first time.
