Embodiment 1
[0020] (1) Take 100g of the bark of Pamarinica bark, remove the sundries, wash with water, dry or air-dry, pulverize, soak in 300mL of distilled water for 6h, then ultrasonicate for 1h, the temperature is 30°C and the power is 80W;
[0021] (2) Pour (1) the Chinese herbal medicine together with the soaking liquid into a volatile oil extractor, extract by steam distillation for 4 hours, and obtain an aqueous solution with volatile oil floating on it;
[0022] (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 belongs to the technical field of the research and development of medical products, and relates to the separation and identification of syringa amurensis rupr. bark volatile oil and a novel application. In the invention, syringa amurensis rupr. barks are taken, cut up after being dried, and processed by ultrasonic for one hour after being soaked by using distilled water for 6 to 8 hours, the temperature is 30 DEG C, and the power is 80W; medicinal materials and soaking liquid are poured into a volatile oil extractor together and are extracted for 4 to 5 hours by adopting a steam distillation method; a water layer is discharged, and the volatile oil extractor is repeatedly washed by ether to enable syringa amurensis rupr. volatile oil to be fully dissolved into the ether; and ether solution dissolved with the volatile oil is poured into a beaker, then anhydrous sodium sulfate is added into the beaker to suck up water, pure volatile oil is obtained after the ether is recovered, and the pure volatile oil is put into a refrigerator of 4 DEG C and preserved for standby. The syringa amurensis rupr. bark volatile oil is analyzed by using a 6890/5973N gas phase color spectrum and mass spectrum united instrument, and comprises the main chemical components of 27.46% of n-hexadecanoic acid, 28.52% of 9,12-octadecadienoic acid (Z,Z), 14.16% of 9,17-octadecadienal and 2.44% of tricosane. The syringa amurensis rupr. bark volatile oil has a suppressing function with different degrees for colibacillus, staphyiococcus aureus, pasteurella, streptococci and salmonella, can be developed into a natural antimicrobial agent applied to the industries of foods, medicines and the like, and can prepare various forms of products with a bacteriostatic function.
Description
technical field [0001] The invention belongs to the technical field of research and development of pharmaceutical products. The invention relates to the separation, identification and 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 isolation, identification, chemical composition and pharmacological effects of the volatile oil from the bark of Cinnamomum bark. There are onl...
