Embodiment 1

[0167] Example 1. Preparation method 1 of Xanthium xanthii total glycosides extract

[0168] Xanthium xanthii dry medicinal material 2.5Kg, with 90% ethanol solution 50 liters of reflux extraction twice, 2 hours each time, the two extracts were combined, and concentrated under reduced pressure to obtain 350g of extract. After dispersing with 2 liters of water, the volume was 6 liters in sequence. Petroleum ether was extracted three times for degreasing, and extracted with 6 liters of chloroform and 6 liters of ethyl acetate to remove impurities; the extraction residue was extracted three times with 6 liters of n-butanol, the extracts were combined and freeze-dried to obtain the total glycosides of Xanthium物21g.

Embodiment 2

[0169] Example 2. Preparation method 2 of Xanthium xanthii total glycosides extract

[0170] Xanthium dry medicinal material 2.5Kg, with 70% ethanol solution 50 liters of ultrasonic extraction twice, 2 hours each time, the two extracts were combined, and concentrated under reduced pressure to obtain 208 g of extract. After dispersing with 2 liters of water, the volume was 6 liters in sequence. Petroleum ether was extracted three times for degreasing, and extracted with 6 liters of chloroform and 6 liters of ethyl acetate to remove impurities; the extraction residue was extracted three times with 6 liters of n-butanol, and the extracts were combined and recovered to dryness under reduced pressure to obtain cocklebur Total glycosides extract 17g.

Embodiment 3

[0171] Example 3 Preparation method 3 of Xanthium xanthii total glycosides extract

[0172] Xanthium dry medicinal material 2.5Kg, extracted twice with 75% ethanol solution 50 liters percolation, each time for 24 hours, the two extracts were combined, and concentrated under reduced pressure to obtain 285 g of extract. After dispersing with 2 liters of water, Liter of petroleum ether was extracted three times for degreasing, and 6 liters of chloroform and 6 liters of ethyl acetate were extracted three times to remove impurities; the extraction residue was extracted three times with 6 liters of n-butanol, and the extracts were combined and recovered under reduced pressure to dryness. 19g of total glycosides of auricularia.

Abstract

The present invention relates to total glycoside extract of Chinese medicine fructus xanthii. Said total glycoside extract includes diterpene compound, phenolic acid compound and total extract of other components, their content ranges respectively are 0.5%-99%, 0.5%-99% and below 0.5%. Said invention can adopt conventional processes of extraction, separation and purification to obtain said total glycoside extract. Said total glycoside extract has the stronger pharmacological action for relieving inflammation, resisting virus, stopping pain and can obtain obvious effect for curing acute and chronic rhinitis, nascsinusitis and related diseases.

Description

Technical field [0001] The invention relates to the technical fields of medicine, food and beverages, in particular to a traditional Chinese medicine extract and a preparation method thereof, and more specifically to a traditional Chinese medicine xanthium total glycoside extract and a preparation method thereof. Background technique [0002] (1) Research overview of Xanthium [0003] 1. General situation of plant resources and application [0004] Fructus Xanthii (Fructus Xanthii), is the dry mature fruit with involucre of Xanthium sibirium Patr. Cangzike, etc., are Chinese pharmacopoeia varieties, which are produced in most areas of China and are extremely rich in resources. Traditional Chinese medicine believes that its taste is bitter, its nature is warm, and it returns to the lung and liver meridians. It has the effects of sweating, dispelling rheumatism, clearing the nose and orifices, and relieving pain. Traditionally used to treat wind-cold headache, rhinorrhea, rubella p...
