Embodiment 1

[0048] Embodiment 1, a kind of method of enriching camphor essential oil antibacterial composition, carries out following steps successively:

[0049] 1), the extraction of camphor essential oil:

[0050] Wash the branches and leaves of Cinnamomum camphora, dry the water on the surface of the leaves at room temperature, cut them into pieces and grind them into powder with liquid nitrogen, use a Clevenger-type device to extract essential oils through steam distillation, and the ratio of solid to liquid between the branches and leaves of Cinnamomum camphora and water vapor is 1g / 4mL, extract for 1 hour, after the obtained reflux solution is allowed to stand for stratification, take the upper layer oily matter, remove water through anhydrous sodium sulfate, and obtain camphor essential oil (crude oil), seal and store in a brown glass bottle at a low temperature of 4 °C store;

[0051] Target component and content thereof are specifically as follows in the camphor essential oil ...

Abstract

The invention discloses a method for enriching antibacterial components of cinnamomum camphora essential oil. The method comprises extraction of the cinnamomum camphora essential oil and also comprises the following steps: taking the cinnamomum camphora essential oil as a raw material, setting the molecular distillation evaporation temperature to be (60 + / -2) DEG C, the system pressure to be (100+ / -10) Pa, the first-stage condensation temperature to be (20 + / -1) DEG C and the second-stage condensation temperature to be (-20 + / -1) DEG C, and carrying out first-stage molecular distillation; taking the obtained first-stage light fraction (1DL) as a raw material, setting the evaporation temperature to be (40 + / -2) DEG C, the system pressure to be (150 + / -10) Pa, the first-stage condensation temperature to be (15 + / -1) DEG C and the second-stage condensation temperature to be (-20 + / -1) DEG C, and carrying out second-stage molecular distillation; and obtaining a second-stage light fraction(2DL). With application of the method, essential oil components can be effectively protected from being damaged.

Description

technical field [0001] The invention relates to a process for enriching antibacterial components of camphor essential oil. Background technique [0002] Cinnamomum camphora (Cinnamomum camphora), originated in southern China, Vietnam and Japan, is a large evergreen tree widely distributed in eastern Asia, Oceania and Pacific islands. Camphor is an important economic tree species in China, and it is also one of the tree species with the highest planting rate in urban greening. The planting area has reached more than 50,000 hectares, and it is increasing year by year. Calculated according to the annual pruning rate of 5%, the branches and leaves produced by pruning in only a medium-sized city can reach 30,000 tons. These discarded branches and leaves can be used to extract camphor essential oil, which can effectively reduce environmental pollution. The essential oils extracted from Cinnamomum genus plants have various antibacterial activities and can be widely used in industr...
