Embodiment 1

[0022] Embodiment 1: the influence of different solid-liquid ratios on essential oil yield

[0023] In this case, petroleum ether is used as the organic solvent, and the ratio of solid to liquid is determined to be no less than 1:1 in the preliminary test. At this time, the yield of essential oil can be guaranteed to be above 0.38% (0.36% higher than that of traditional water distillation under the same conditions) ). Within the range of solid-liquid ratio, we selected seven nodes of 1:1, 1:3, 1:5, 1:7, 1:9, 1:11 and 1:13 to carry out representative trend experiments, and the results can be found in figure 1 shown. from figure 1 It can be seen that when the above seven material-liquid ratios are used for experiments, the yield of essential oil increases with the increase of the ratio of solid-liquid, and the yield of essential oil increases significantly. When the ratio of solid-liquid to 1:5, the yield of essential oil has already Around 0.42%; continue to increase the rat...

Embodiment 2

[0025] Embodiment 2: The influence of different extraction temperatures on the yield of essential oil

[0026] On the basis of embodiment 1, we carry out experiment to the extraction temperature in Soxhlet extraction (all the other parameters are referring to embodiment 1), the result shows: combine figure 2 , when the extraction temperature is set at 65°C, the extraction rate of essential oil has reached 0.39%, which is 0.35-0.36% higher than that of traditional water distillation; as the extraction temperature increases, the extraction rate increases almost linearly; When it reaches 80°C, the yield of essential oil reaches the peak value (0.46%) under this condition; if the temperature continues to rise, the solvent may be overboiled due to excessive temperature, and the stripping of the target essential oil will be hindered, and the extraction rate will not be significantly improved. growth, and basically maintained around 0.45-0.46%. Therefore, under comprehensive consid...

Embodiment 3

[0027] Embodiment 3: The influence of different extraction time on the yield of essential oil

[0028] On the basis of embodiment 1 and embodiment 2, we experiment to the extraction time of Soxhlet extraction (referring to embodiment 1 for all the other parameters), the result shows: image 3 , with the prolongation of the extraction time of the raw material powder in the organic solvent, the yield of the essential oil gradually increases. When the extraction time reaches 3 hours, the extraction rate of the essential oil reaches the maximum, and the extraction rate of the essential oil is 0.458% at this time; continue to extend the extraction time, the extraction time At 3-4h, the increase was no longer significant, and the yield of essential oil tended to be stable around 0.458%-0.46%. Therefore, considering the comprehensive treatment effect and treatment cost, when the extraction time is selected at 0.5-4 hours, and preferably 2-3.5 hours, the extraction effect of essential...

Abstract

The invention provides a soxhlet extractor method of borneol essential oil, and belongs to the technical field of recycling or refining the essential oil from raw materials. The soxhlet extractor method comprises the steps that cinnamomum camphora leaves are taken and dried; the dried cinnamomum camphora leaves are subjected to mechanical activation in a stirred ball mill to obtain powder; the powder and an organic dissolvent are mixed according to material-liquid ratio, heating is carried out to perform soxhlet extraction, and a crude product of the borneol essential oil is obtained; the crude product of the borneol essential oil is concentrated in vacuum, and a finished product of the borneol essential oil is obtained. The soxhlet extractor method is applied to essential oil extraction,and the soxhlet extractor method has the advantages that the extraction efficiency is high, the pertinence and accuracy are significant, high polar components can be extracted, components with large molecular weight can be extracted and the like.

Description

technical field [0001] The application relates to a Soxhlet extraction method of borneol essential oil, which belongs to the technical field of recovering or refining essential oil from raw materials. Background technique [0002] Natural borneol, formerly known as dipteroxiang, also known as d-borneol, is a natural and precious traditional Chinese medicine and food additive, and is an indispensable and good adjuvant in many borneo products. In my country, natural borneol has been used as medicine for more than 1500 years. Studies have shown that borneol has been proven to have anti-inflammatory, anti-thrombotic and excellent antioxidant effects. [0003] Borneo essential oil is suitable for preparing tobacco essence, medical essence, cosmetics and various medicines. Borneo essential oil has high value and wide application, and the development prospect of borneol is broad. However, in recent years, there are few research reports on the extraction of borneol essential oil. ...
