Embodiment 1

[0011] Wash the fresh lily bulbs, pack them in gauze bags for 20 kg, put them into a 200-liter extraction tank, first use 80% ethanol to reflux at 75°C for 10 hours, transfer the ethanol reflux liquid to the concentration tank, and use it for further separation and purification of lily plant total alkaloids ; Then, in the extraction tank after alcohol extraction, add deionized water to the lily solid, extract at 95°C for 2 hours, transfer the water extract to the concentration tank, and use it to extract lily polysaccharides. Finally, the filter residue in the extraction tank after water extraction is used for the extraction and processing technology of lily starch and lily dietary fiber.

Embodiment 2

[0013] Pack 15 kg of dried lily bulbs in a gauze bag, put them into a 200-liter extraction tank, first add deionized water to the extraction tank, extract at 95°C for 2 hours, transfer the water extract to the concentration tank, and re-extract 3 times, The combined extracts are used to extract lily polysaccharides. Then add 80% ethanol to the lily residue after water extraction, reflux at 65° C. for about 8 hours, transfer the ethanol reflux liquid to a concentration tank, and use it in the extraction process of total alkaloids of lily plants. The residue in the extraction tank after alcohol extraction is used for the extraction and processing technology of lily starch and lily dietary fiber.

Embodiment 3

[0015] Wash the fresh lily bulbs, pack them in gauze bags for 20 kg, put them into a 200-liter extraction tank, reflux them with 80% ethanol at 80°C for about 8 hours, transfer the ethanol reflux to the concentration tank, and use them in the extraction process of total alkaloids of lily plants. In the extraction tank after alcohol extraction, add deionized water to the lily solid, extract at 95°C for 2 hours, transfer the water extract to the concentration tank, re-extract twice, and combine the extracts to extract lily polysaccharides. The filter residue in the extraction tank after water extraction is used for the extraction and processing technology of lily starch and lily dietary fiber.

[0016] The resulting alcohol extract is concentrated in a concentration tank to obtain a lily plant total alkaloid extract; the extract is dissolved in deionized water (at 50-60°C), and the insolubles are removed by filtering under reduced pressure at normal temperature; the water extract...

Abstract

The invention provides a process for extracting and purifying lily alkaloid total alkali. The process comprises: extracting lily alkaloid total alkali by alcohol while extracting lily polysaccharide major product by water, then separating and purifying the lily alkaloid total alkali; thereby, the extraction cost of the lily alkaloid total alkali is largely reduced, the lily raw material is comprehensively utilized and both edible and pharmaceutical characters of the lily are fully embodied; The invention is a new process for extracting and purifying lily alkaloid total alkali which is suitable for industrial production.

Description

technical field [0001] The invention relates to a process for extracting effective components of lily, in particular to a process for extracting total alkaloids of lily. Background technique [0002] Alkaloids are an important class of natural organic compounds, which refer to cyclic compounds that contain nitrogen atoms in a negative oxidation state and exist in biological organisms. Alkaloids are mostly biologically active and are the active ingredients of many medicinal plants. Lily contains a variety of alkaloids such as colchicine. Colchicine (colchicine) is an important alkaloid originally discovered from the lily plant colchicine. It is a kind of ketone alkaloid, which can inhibit cell mitosis and the growth of cancer cells. It is clinically used to treat cancer and gout. and other diseases, colchicine is also a commonly used reagent in cell biotechnology. [0003] Lily bulbs contain about 0.38% of total alkaloids. Although the content is low and the extraction cos...
