Embodiment 1

[0018] (1) Take 100g of the bark of Pamarinica bark, remove the sundries, wash with water, dry or air-dry, crush, soak in 400mL distilled water for 12h, then ultrasonicate for 30min, the temperature is 30°C and the power is 80W;

[0019] (2) Pour (1) the Chinese herbal medicine together with the soaking liquid into a volatile oil extractor, extract by steam distillation for 3 hours, and obtain an aqueous solution with volatile oil floating on it;

[0020] (3) Release the aqueous solution with volatile oil floating in (2) into the water layer, wash the volatile oil extractor repeatedly with ether to fully dissolve the volatile oil of Matinica citrus in the ether, pour the ether solution in which the volatile oil is dissolved into a beaker, and then Add anhydrous sodium sulfate to the beaker to absorb the water, recover the ether to obtain pure volatile oil, and store it in the refrigerator at 4°C for later use.

Embodiment 2

[0022] (1) Take 200g of the bark of Pamarinica bark, remove the sundries, wash with water, dry or air-dry, crush, soak in 600mL distilled water for 12h, then ultrasonicate for 30min, the temperature is 30°C and the power is 80W;

[0023] (2) Pour (1) the Chinese herbal medicine together with the soaking liquid into a volatile oil extractor, extract by steam distillation for 3 hours, and obtain an aqueous solution with volatile oil floating on it;

[0024] (3) Release the aqueous solution with volatile oil floating in (2) into the water layer, wash the volatile oil extractor repeatedly with ether to fully dissolve the volatile oil of Matinica citrus in the ether, pour the ether solution in which the volatile oil is dissolved into a beaker, and then Add anhydrous sodium sulfate to the beaker to absorb the water, recover the ether to obtain pure volatile oil, and store it in the refrigerator at 4°C for later use.

Abstract

The invention relates to a new preparation technology and new applications of syringa amurensis rupr bark volatile oil, belonging to the technical field of research and development on medical products. The preparation technology comprises the steps of: drying and cutting up syringa amurensis rupr bark, soaking the syringa amurensis rupr bark in distilled water for 12 hours and conducting ultrasonic treatment for 30 minutes at temperature of 30 DEG C and with power of 80W; pouring medicinal materials together with soak solution into a volatile oil extractor and conducting extraction for 3 hours by adopting a water vapour distillation method; releasing water-yielding stratum and washing the volatile oil extractor repeatedly with ether so as to lead the syringa amurensis rupr volatile oil to be dissolved in the ether completely; and pouring the ether solution dissolved with volatile oil into a beaker, adding anhydrous sodium sulfate in the beaker to suck dry moisture and recycling the ether to obtain the purified volatile oil, and then storing the volatile oil in a refrigerator at temperature of 4 DEG C for standby. The syringa amurensis rupr bark volatile oil has inhibitory actions with different degrees on colon bacillus, staphylococcus aureus, pasteurella, streptococcus and salmonella, therefore the volatile oil can be developed into natural antibacterial agent used for industries of food and medicament, and the like, and prepare various products with antibacterial effects.

Description

technical field [0001] The invention belongs to the technical field of research and development of pharmaceutical products. The invention relates to a new preparation process and a new application of the volatile oil from the bark of Syringa amurensis Rupr. Background technique [0002] Syringa amurensis Rupr. is one of the common medicinal plants in Changbai Mountains. In my country, it is mainly distributed in Jilin, Liaoning, North China, Northwest China and Central China, with rich resources. The bark, trunk and branches can be used medicinally. It tastes bitter and slightly cold in nature. Modern pharmacological experiments have proved that it has the functions of clearing the lungs and eliminating phlegm, relieving cough, relieving asthma, reducing inflammation and diuresis. [0003] At present, there are few reports on the volatile oil, chemical components and pharmacological effects of the bark of Cinnamomum bark. There are only a few reports on the isolation of sev...
