Abstract:

The volatile oils of the flower, leaf, stem and fruit from Amygdalus persica var. persica f. duplex extracted by supercritical carbon dioxide are analyzed by GC-MS. There are 178 components identified and their relative mass fractions are determined. The main constituents and mass concentration are benzaldehyde(11.42%), α-farnesene(9.18%) and n-hexadecanoic acid(8.03%) from the flower, benzaldehyde(14.72%), pentacosane(9.85%), octacosane(8.29%) and tricosane(5.14%) from the leaf, (Z)-3- hexen-1-ol(28.90%), (E)-2-hexen-1-ol(16.06%) and 1-hexanol(6.86%) from the stem, benzaldehyde(20.46%), n-hexadecanoic acid(5.84%) and benzyl alcohol(5.01%) from the fruit. The volatile oils of the flower, leaf, stem and fruit lower the contents of peroxides and acid value of peanut oil during 10~40 d storage period. The volatile oils of the flower and stem show significant antimicrobial activities with the minimum inhibitory concentration(MIC) of 0.024~0.188 g/L.

Key words: Amygdalus persica var. persica f. duplex, volatile oil, chemical components, antioxidation, antimicrobial activities
