Embodiment 1

[0027] The method for preparing dioscin from Penicillum dioscin 051016 (Penicillum dioscin 051016) CCTCC No: M206001 is carried out according to the following steps.

[0028] 1. Clean the yam raw material;

[0029] 2. Crushing the raw material to less than 5mm;

[0030] 3. Sterilize directly at 100°C for 0.5-1 hour, or add 0.5% ammonia water by weight of raw materials, mix well, and place at 25°C-28°C for 1 hour;

[0031] 4. Add Penicillumdioscin 051016, CCTCC No: M206001, with 0.1% of raw material weight at 25°C-28°C, stir evenly, and ferment at 25°C-28°C for 24-36 hours under the condition of pH 4-7;

[0032] 5. Add water that is 4 times the weight of the fermentation material;

[0033] 6. Stir and filter, dry the filter residue at 60°C to 70°C, then add petroleum ether with a boiling range of 60°C to 90°C that is 3 to 5 times the weight of the filter residue;

[0034] 7. Reflux extraction at 60°C for 2 to 3 times, and combine the extracts;

[0035] 8. Recover petroleum ...

Abstract

The invention discloses a method for preparing dioscin by using Penicillum dioscin051016, CCTCC No: M206001, and relates to the preparation of dioscin. The production method comprises: crushing yam, sterilizing, mixing dioscin penicillium, fermenting at pH 4-7 at 25-28 DEG C for 24-36 hours, refluxing extraction with petroleum ether, crystallizing, drying to obtain diosgenin. Compared with the prior art, the present invention has the following advantages: 1. No acidic organic waste water pollutants are produced; 2. The present invention ferments at normal temperature, which reduces production energy consumption and production cost.

Description

Technical field: [0001] The invention relates to the preparation of diosgenin, and more specifically relates to the preparation of diosgenin by the fermentation method of Penicillium diosgenin. Diosgenin is the main raw material for the production of steroid hormones. Background technique: [0002] Dioscin is extracted from plants of the genus Dioscorea, and turmeric is the main resource for extracting diosgenin. There are more than 200 kinds of synthetic drugs using diosgenin as raw materials, among which more than 60% of steroid hormones use diosgenin as raw materials. [0003] The traditional method of extracting diosgenin from yam raw material is acid hydrolysis. The extraction process using the acid hydrolysis method will produce a large amount of acidic organic wastewater to pollute the environment and rivers in the production area, and the sewage treatment will greatly increase the production cost. Therefore, people have been trying to replace acid hydrolysis with ...
