Abstract

The paper is to explore the best extraction process of volatile oil and extract the volatile oil from Prunusmume so as to analyze the constituents of the essential oil from Prunusmume. And the antibacterial activity of the volatile oil was tested. In the experiment, the volatile oil was extracted from the dried Prunusmume by steam distillation, and the extraction process was optimized by orthogonal experiment. The chemical composition of the volatile oil was separated and identified by gas chromatography-mass spectrometry (GC-MS). The antibacterial activity of volatile oil from Prunusmume was tested by pore and tube dilution method. And the best extraction process of volatile oil from Prunusmume was as follows: adding water for 20 times, soaking for 3 hours, extraction for 8 hours. Volatile constituents mainly contain Alkanes, aldehydes and esters. Volatile oil on the test with E.coli and Staphylococcus aureus has shown a good antibacterial effect. It can be concluded that the optimum extraction process of volatile oil from Prunusmume was stable and feasible. At the same time, it has a good antibacterial effect.
