Embodiment Construction

[0028] Further detailed explanation through specific implementation mode below:

[0029] A southern crane lice extract, the extract is 11-acetoxy-8β-angeloyloxy-15-methoxy-4α,5α-epoxyguaiacol-3-one, and its chemical structure is :

[0030] .

[0031] The extraction method for extracting 11-acetoxy-8β-angeloyloxy-15-methoxy-4α,5α-epoxyguaiacol-3-one from the southern crane louse comprises the following steps:

[0032] 1) Take the southern crane lice, after drying and crushing, reflux extraction with ethanol with a volume fraction of 70-95%, preferably 95%, for 4 times, each extraction for 2 hours, and combine the extracts to concentrate under reduced pressure to obtain ethanol extract;

[0033] 2) After dissolving and dispersing the ethanol extract obtained in step 1) in water, extract with petroleum ether and ethyl acetate for 3 times respectively, and concentrate the extraction parts obtained by each extractant under reduced pressure to obtain extracts of various parts; ...

Abstract

The patent of the present invention discloses a new extract of the southern crane lice and its extraction method, the extract is: 11-acetoxy-8β-angeloyloxy-15-methoxy-4α,5α-epoxyhexa Chuanglin-3-one, its chemical structure is:

Description

technical field [0001] The invention relates to the field of extraction of phytochemical components, in particular to an extract of the southern crane louse and an extraction method thereof. Background technique [0002] The southern crane louse is the Umbelliferae wild carrot ( Daucus carota L.) dry ripe fruit. Studies have shown that the southern crane lice has insecticidal, antibacterial, antidiarrheal, anti-inflammatory, analgesic, coronary artery expansion and liver protection effects, and has great development and application prospects. In the prior art, the method of separating sesquiterpenoids from the southern crane lice has been published as follows: (1) extract the southern crane lice twice with ethanol, combine the extracts, recover the ethanol, and obtain the total extract, the total extract Sequentially extract with petroleum ether, chloroform, ethyl acetate and n-butanol to obtain 5 polar parts; each part is separated by silica gel column chromatography unde...
