The chemical composition of Fructus Amomi essential oil was analyzed.Meanwhile,fresh strawberry(Fragaria ananassa Duch.cv.Hongshimei) was used as the experimental material and different concentrations of Fructus Amomi essential oil was applied to study on the preservation effects of the strawberry.The results showed that the composition of Fructus Amomi essential oil were relatively complex and the mainly contained cadinol(11.41%),mythyl ester of octadecenoic acid(8.99%),naphthalene acetaldehyde(5.06%) and mythyl ester of hexadecanoic acid(4.73%).The Fructus Amomi essential oil showed remarkable effects on the preservation of strawberry at the concentration between 80~160μg/mL.The decay index decreased,the losing speed of soluble solid,total sugar and vitamin C on strawberry were all effectively reduced and the storage life time was extended.
