Abstract:

To analyze the chemical constituents of the essential oils of leaf, stem, and fruit from Euonymus japonicus Thunb. and study their antiviral activities, the volatile oils were extracted by supercritical carbon dioxide and were separated and identified by GC-MS. Their antiviral activities in vitro were inspected. There are 133 components identified, in which the main constituents are 2-ethoxy-propane(41.92%), (E)-2-hexen-1-ol(17.80%), (E)-3,7-dimethyl-2,6-octadien-1-ol(7.86%), methyl cyclohexane(6.60%) from the leaf volatile oil, methoxy phenyl oxime(33.10%), octacosane(14.34%), α-methyl-α-[4-methyl-3-pentenyl]oxiranemethanol(12.48%), toluene(11.88%)and heneicosane(7.74%) from the stem volatile oil and benzaldehyde(15.52%), toluene(15.03%), methyl cyclohexane(14.76%) and (Z)-3-hexen-1-ol(10.98%) from the fruit volatile oil. The volatile oils of the leaf, stem and fruit extracted by cyclonexane and ether show special inhibiting activities against some viruses. Chemical compositions of the volatile oils of the leaf, stem, and fruit show significant differences and special antiviral activities.

Key words: leaf,stem,and fruit from Euonymus japonicus Thunb., volatile oil, chemical components, antiviral activities
