Embodiment 1

[0028] A method for separating and purifying linoleside compounds, the specific steps are as follows:

[0029] Soak and extract the dried and crushed Weixian radish or radish stem and leaf dry powder at room temperature for four times with methanol. The dry powder can be soaked for five days and then filtered to obtain a crude extract; the filter residue is soaked and filtered with the same amount of methanol as the previous time, and soaked four times, each time for five days; the four crude extracts are combined, vacuum reduced Concentrate under pressure to obtain a viscous dark green extract with a solid content of 30-60 wt%.

[0030] The above-mentioned extract is diluted according to the ratio of 1g of extract to 2-5g of distilled water, extracted three times with petroleum ether, combined with the petroleum ether extract after petroleum ether extraction, concentrated under vacuum and reduced pressure to obtain the extract of petroleum ether, and poured Add petroleum eth...

Embodiment 2

[0051] A method for separating and purifying linoleside compounds, the specific steps are as follows:

[0052] Soak and extract the dried and crushed Weixian radish or radish stem and leaf dry powder at room temperature for four times with methanol. The dry powder can be soaked for five days and then filtered to obtain a crude extract; the filter residue is soaked and filtered with the same amount of methanol as the previous time, and soaked four times, each time for five days; the four crude extracts are combined, vacuum reduced Concentrate under pressure to obtain a viscous dark green extract with a solid content of 50-60 wt%.

[0053] The above-mentioned medicinal extract was diluted according to the ratio of adding 4 g of distilled water to 1 g of medicinal extract, extracted three times with petroleum ether, combined the petroleum ether extract after petroleum ether extraction, concentrated under vacuum and reduced pressure to obtain petroleum ether part extract, and adde...

Embodiment 3

[0059] A method for separating and purifying linoleside compounds, the specific steps are as follows:

[0060] Soak and extract the dried and crushed Weixian radish or radish stem and leaf dry powder at room temperature for four times with methanol. The dry powder can be soaked for five days and then filtered to obtain a crude extract; the filter residue is soaked and filtered with the same amount of methanol as the previous time, and soaked four times, each time for five days; the four crude extracts are combined, vacuum reduced Concentrate under pressure to obtain a viscous dark green extract with a solid content of 30-50 wt%.

[0061] After the above-mentioned extract is diluted according to the ratio of 1g of extract to 3g of distilled water, it is extracted three times with petroleum ether, and the petroleum ether extract after petroleum ether extraction is combined, concentrated under vacuum and reduced pressure to obtain extract of petroleum ether part, and added to the...

Abstract

The invention belongs to the field of plant science, and provides a novel flax cerebroside compound and a method for extracting the compound from radishes and radish stems and leaves. The compound is separated and purified mainly by using chromatographic techniques such as silica-gel column chromatography, and methanol extracts of Weixian county radishes and radish stems and leaves are subjected to chemical component separation and purification, and the compound obtained by separation is structurally identified as a novel flax cerebroside compound in the aspects of physical and chemical properties, MS and NMR and the like; and the compound is separated from land plants firstly, and also separated from radishes and radish stems and leaves which are frequently eaten by people for the first time, and therefore, the compound has various important biological activities and important economic and social significances.

Description

technical field [0001] The invention belongs to the field of plants and provides a new linoleglycoside compound and a method for extracting the linolecenside compound from Weixian radish or radish stems and leaves. Background technique [0002] Weixian radish and its stems and leaves are common vegetables with excellent food and medicine. It can be raw or cooked, it can be fermented or sauced, it can be fermented or vinegared, it can be sugared or cooked, and it is the most beneficial among vegetables. Its biggest feature is that it is excellent in food and medicine, sweet and juicy, tight in texture, slightly spicy, crisp and delicious in food, and resistant to storage; it can be served cold, stir-fried, boiled in soup, eaten raw as fruit, or processed Pickles are widely used. Its main medicinal functions are to eliminate stagnant stagnation, resolve phlegm and heat, lower qi, relax the middle, and detoxify; it is traditionally used for weak spleen and stomach, fullness o...
