Embodiment 1

[0025] A method of extracting ethyl-α-D-furana sugar from Nigella Sativa seeds, including the following steps:

[0026] 1) Take the raw material for 5kg dry Nigella Sativa seeds. After crushing at room temperature, it is immersed with 7L petroleum ether with 7L petroleum ether, 3 times per degrease time of 3 days), and the residue can smooth the petroleum ether, and cool it with 70% ethanol. Exception 3 (addition ratio of the residue and 70% ethanol), 5 kg: 7L), 3 days, combined with extract, and recovered solvent to obtain an extract.

[0027] 2) Dissolve the extract to dissolve with methanol, mix in the silica gel column, and use the volume ratio of 20: 1, 15: 1, 10: 1, 5: 1, 3: 1, 1: 1 dichloromethane - Methanol elutes the silica gel column, silica gel thin layer chromatographic test, resulting in seven components, and marked as FR1-FR7 in sub-polarity according to the resulting group;

[0028] 3) Separate the component 2 by reverse phase column chromatography eluting with a vo...

Abstract

The present invention relates to a Nigella sativa Extracted from the seeds to isolate the compound ethyl‑ α ‑D‑Arabinofuranose Method: Choose Dried Nigella sativa Seeds are used as raw materials, crushed and degreased with petroleum ether, extracted with ethanol at room temperature, dissolved in methanol, mixed with silica gel and loaded, eluted with dichloromethane and methanol to obtain Fr1‑Fr77 components, and then through continuous separation and purification, the pure compound is obtained. The method of the present invention is conducive to better development and utilization Nigella sativa This medicinal plant is conducive to the sustainable utilization of plants; the extraction process of the present invention is simple, and it is easy to obtain ethyl- α ‑D‑arabinofuranose compound monomer, the solvent can be recycled, the extraction amount is large, and it can be produced industrially.

Description

Technical field [0001] The present invention belongs to the field of plant extraction separation, and in particular, a method of efficient and rapidly extracting the separated compound ethyl-D-furan sugar from NiGella Sativa seeds. Background technique [0002] Nigella Sativa seeds are dried seeds of Nigella Sativa, Nigella Sativa, nigella Sativa, which originates from Southwest Asia, is widely distributed in Mediterranean, Central Europe, Western Asia and other places; its seed oil is used as edible oil in the Middle East and North Africa, etc. The Egyptian area is widely used, but also for health food against disease, widely used in food. The main components of Nigellasativa seeds have flavonoids, saponins, alkaloids, steroids, and phenols, etc., and also contain a lot of grease. Nigella Sativa seeds have a variety of pharmacological effects, including antibacterial, antioxidant, anti-cancer, anti-inflammatory, hypoglycemic, liver, diuretic, etc. [0003] Currently, there is no...
