Embodiment 1

[0012] 1, the method for the separation and identification of the volatile oil component of the leaf crab beetle leaf, is characterized in that comprising the following steps:

[0013] Step (1): Weigh 100g of dry Crabbeta leaf coarse powder, put it in a glass container after crushing, add 500ml of distilled water to soak for 5h, and ultrasonic for 1h at a temperature of 30°C and a power of 80W;

[0014] Step (2): Pour the coarse leaf powder and the soaking liquid of the Chinese crab beetle into the volatile oil extractor in (1), and extract 4 by steam distillation to obtain an aqueous solution with volatile oil floating on it;

[0015] Step (3): Release the aqueous solution with volatile oil floating on it in (2), and repeatedly wash the volatile oil extractor with ether to fully dissolve the volatile oil of the leaves of Crabgrass fragrans into the ether, and pour the ether solution containing the volatile oil into In the beaker, add anhydrous sodium sulfate to the beaker to ...

Embodiment 2

[0019] 1, the method for the separation and identification of the volatile oil component of the leaf crab beetle leaf, is characterized in that comprising the following steps:

[0020] Step (1): Weigh 100g of dry Crabbeta leaf coarse powder, put it in a glass container after crushing, add 600ml of distilled water to soak for 6h, and ultrasonic for 1h at a temperature of 30°C and a power of 80W;

[0021] Step (2): Pour the coarse leaf powder and the soaking liquid of the Chinese crab beetle into the volatile oil extractor in (1), extract by steam distillation for 5 hours, and obtain an aqueous solution with volatile oil floating on it;

[0022] Step (3): Release the aqueous solution with volatile oil floating on it in (2), and repeatedly wash the volatile oil extractor with ether to fully dissolve the volatile oil of the leaves of Crabgrass fragrans into the ether, and pour the ether solution containing the volatile oil into In the beaker, add anhydrous sodium sulfate to the be...

Abstract

The invention belongs to the technical field of medicine production research development, and relates to isolation and identification as well as application of volatile oil elements of Parasenecio firmus leaf. The isolation and identification of the volatile oil elements of the Parasenecio firmus leaf are realized by the following steps of: weighing dried Parasenecio firmus leaf, and extracting ultrasonically by a water steam distillation method to obtain the volatile oil; and analyzing the obtain volatile oil by utilizing a 6890 / 5973N gas chromatograph-mass spectrometer. The obtain volatile oil mainly comprises the following chemical elements in proportion: 18.98% of n-palmitic acid, 9.89% of 1-tridecylene, 8.05% of caryophyllene epoxide, 6.04% of (S)-undeca-cycloolefin, 3.84% of 9,12,15-octadecatrienoic acid, 2.97% of (-)-spathulenol, 2.83% of kaurene and 2.12% of caryophyllene. The volatile oil is used for preparing pharmaceutical preparation capable of restraining escherichia coli, streptococcus, Salmonella, Pasteurella and staphylococcus aureus.

Description

technical field [0001] The invention belongs to the technical field of research and development of pharmaceutical products. The present invention relates to the separation, identification and application of the volatile oil components of the leaves of Crabgrass chinensis. Background technique [0002] Parasenecio firmus Kom (Parasenecio firmus Kom. The synonym is cacalia firma kom.), a plant of the genus Parasenecio or cacalia in the Compositae family (compositae), also known as Parasenecio firmus Kom, which is eaten as a wild vegetable in the folk. Mainly distributed in Jilin (Fusong, Changbai Mountains, Hunjiang River), growing under dense forests or forest margins and open spaces in forests, 800-1100 meters above sea level. North Korea is also distributed. After literature search, it was found that there are few reports on the related research on Crabbeta spp. at home and abroad. Contents of the invention [0003] 1, the method for the separation and identification o...
