| Abstract: | The microcapsule and aqueous two-phase system extraction technique was applied to investigate the effects of β-cyclodextrin,Sodium sulphate,temperature and time on the yield of oil from Thymus quinquecostatus.The optimal extracting conditions were as follows:β-cyclodextrin 45 %,Sodium sulphate 20 %,temperature 40 ℃,time 20 min.The average receiving rate of thyme oil is 96.67 %.Bacteriostasis experiment results show that Thyme oil has a good antibacterial effect,its bacteriostasis effect is better than that of 0.1 % potassium sorbate. |
