Embodiment Construction

[0038](2) Extraction: Input the above-mentioned fine powder into the continuous countercurrent ultrasonic extraction machine, and at the same time, input ethanol with a volume percentage concentration of 80% into the continuous countercurrent ultrasonic extraction machine. The amount of the above-mentioned ethanol is: add 5 The above-mentioned ethanol was raised, and a total of 2450 L of ethanol was input during the whole extraction process; when ultrasonic extraction was used, the extraction temperature was normal temperature, and the extraction time was 70 minutes; when ultrasonic extraction was not used, the extraction temperature was 60 ° C, and the extraction time was 120 minutes; after extraction, the obtained Dioscorea chrysanthemum leaf residue and 1570L extract;

[0039] (2-1) Desolventization: Squeeze the Dioscorea chrysanthemum residue obtained after extraction in step (2), the liquid content in the Dioscorea chrysanthemum residue after squeezing is between 65% and 7...

Abstract

A preparing method of dioscorea composita saponin successively comprises the following steps: (1) pretreating raw material, (2) extracting, (3) concentrating, (4) acidizing and hydrolyzing, (5) carrying out heat reflux tripping, and (6) crystallizing, and thus obtaining the dioscorea composita saponin. The preparing method of the dioscorea composita saponin adopts a condensation method to recycle ethanol, ethanol tail gas is recycled for reutilization, and thus zero emission is achieved; moreover, the consumption amount of ethanol in the entire production process is less than 1%, therefore, the ethanol consumption is reduced, and in addition, the environment is protected. At the same time, during the ethanol recycling process, hot water is formed after circulating cooling water is subjected to heat exchange with ethanol steam, the hot water flows back to a continuous countercurrent ultrasonic extraction machine and is used for heating the continuous countercurrent ultrasonic extraction machine, and thus waste heat of the ethanol steam is effectively utilized, and energy is saved. In addition, dioscorea composita can be used as a main ingredient of an animal feed after the saponin component is extracted, and thus the problem of dioscorea composita waste residue treatment is completely solved.

Description

technical field [0001] The invention relates to a method for preparing diosgenin, more specifically, the invention relates to a method for preparing diosgenin from chrysanthemum leaves. Background technique [0002] Dioscorea chrysanthemum belongs to the perennial tall vine of Dioscoreaceae, native to Mexico, and diosgenin in diosminum is an important basic raw material for the production of synthetic steroid hormone drugs. It has been cultivated extensively in tropical regions. [0003] Although diosgenin has been produced as an important medical raw material for several decades, the current diosgenin production method is still quite backward, and the existing diosgenin production method generally has high production cost, low production efficiency, and production of diosgenin. A large amount of waste water and waste residue, serious environmental pollution and other defects. Therefore, improving the backward production method of diosgenin has become an urgent technical p...
