[0035] Weigh 20.0 kg of fly powder, add it into a reaction tank equipped with 50 liters of 70% (V / V) ethanol while stirring at room temperature, extract for 1 hour, stir while soaking, the rotating speed is 120 rpm, 1200 rpm / separation After 20 minutes, the reaction mixture was transferred to a 300-mesh cloth bag, pressed to dryness with a hydraulic press, and the extruded solution was recovered and the above leaching steps were repeated three times (the dry matter after the extruded solution was recovered, vacuum dried and recycled); Take out the solution and transfer it to a distillation recovery device, recover the ethanol under reduced pressure and 70-100°C for later use, slip out the residual liquid after the ethanol, and collect the oil phase by standing and layering; freeze-dry and concentrate the water phase to 50 degrees Brix , and then extracted and purified with ethyl acetate, the oil phase was collected and all oil phases were combined, and concentrated to dryness t...

Embodiment 3

[0037] Weigh 20.0 kg of fly powder, add 50 liters of 85% (V / V) ethanol to the reaction tank while stirring at room temperature, stir while soaking, the rotating speed is 50 rpm, leaching for 1.5 hours, 1200 rpm / centrifugation for 20 minutes , and then transferred to a 200-mesh cloth bag, pressed dry with a hydraulic press, recovered the extruded solution and repeated the above leaching steps three times; combined the recovered extruded solution and transferred it to a distillation recovery device, and recovered it under normal pressure and 70-100°C Ethanol, the residual liquid after slipping out of ethanol, let stand to separate and collect the oil phase; lyophilize and concentrate the water phase to 50 degrees Brix, then extract and purify with ethyl acetate, collect the oil phase and combine all the oil phases, and concentrate to Dry to obtain 382.0 g of dark brown paste. Dissolve the dark brown paste substance in 1000 milliliters of 70% (V / V) ethanol, remove solid impuritie...

Abstract

The invention discloses konjak ceramide and an extraction method thereof. The method for extracting and separating the ceramide comprises the following steps: (1) soaking konjak byproduct and/or wastes used as raw materials with 45%-85% (V/V) ethanol for 1-2 hours, collecting leachate, transferring the leachate to a distillation and recovery device, standing for layering, collecting oil phase, decompressing and/or performing freeze-dry concentrating on water phase, then extracting and purifying the water phase with ethyl acetate, and collecting oil phase, combining all the oil phases, and concentrating the combined oil phase to be in a paste state; and (2) dissolving the concentrate with 45%-80% (V/V) ethanol, extracting with the ethyl acetate, extracting the ethanol phase with petroleum ether, combining the residual liquids of ethyl acetate and petroleum ether, and drying and concentrating to remove the solvent and obtain a crude product containing 0.5-20% of konjak ceramide.

Description

technical field [0001] The invention relates to a ceramide substance and an extraction method thereof, in particular to a konjac ceramide and a method for extracting and separating the ceramide from konjac by-products and waste. Background technique [0002] Ceramide is widely found in animals and plants. It is an amide formed by condensation of sphingosine and long-chain fatty acid. It is composed of a long-chain base and a long-chain fatty acid. It is also called N-fatty acylceramide . Ceramide exists in the interstitial cells of the stratum corneum, plays a key role in the physiological functions of the stratum corneum, and plays a leading role in the regulation of the skin barrier function, mainly including: barrier function, polymerization, moisturizing effect, anti-aging effect, anti-allergy Function, whitening effect, make the skin smooth and delicate, prevent the skin from drying out due to water loss. In addition to participating in the regulation of skin barrier ...
