Problems solved by technology

[0004] There are many extraction and separation methods of Pueraria total flavonoids and puerarin, but many of them still have defects. For example, in the current domestic production, the extraction of Pueraria flavonoids mainly adopts the traditional process of alcohol extraction, leaching, and lead salt precipitation. organic solvents, the energy consumption is large, the time is long, and the efficiency is low
These have caused the waste of resources and the pollution of the environment, and the economic benefits are also low

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, a kind of simple and efficient comprehensive production method of kudzu root total flavonoids, puerarin and kudzu root starch provided by the present embodiment, its step process is as follows:

[0024] (1) Wash and slice fresh kudzu root, dry, crush and sieve, and weigh.

[0025] (2) Take Pueraria root with a particle size of 80 mesh, pre-soak for 1 hour, and its solid-liquid ratio is 1g: 25ml. Under normal pressure, use a microwave power of 800W to irradiate the wet Pueraria root intermittently for 3 times, each time for 40 seconds , using 80% ethanol solvent to extract the wet pueraria root, the extraction temperature is 80° C., the extraction time is 60 minutes, after cooling and filtering, the total flavonoids extract and filter residue of pueraria root are obtained.

[0026] (3) Evaporate the solvent from the total flavonoids e...

Abstract

The invention provides a technological method for comprehensively producing pueraria flavonid, puerarin and arrowroot starch, which belongs to the field of extracting effective ingredients from plants, and comprises the following steps: adopting a 80% ethanol microwave assisted extraction technology to obtain a pueraria flavonid solution and filter residue; adopting a macroporous resin adsorption method (AB-8 resin) to purify the pueraria flavonid solution and obtain the pueraria flavonid and puerarin products; and soaking the extracted filter residue by water, and separating the precipitation to obtain the arrowroot starch. The invention realizes the purpose of synchronously extracting the pueraria flavonid, the puerarin and the arrowroot starch from the radix puerariae, and effectively improves the product extraction rate.

Description

technical field [0001] The invention relates to a processing method for extracting effective substances from plants, in particular to a process for comprehensively producing total flavonoids, puerarin and pueraria starch. Background technique [0002] Pueraria lobata is not only a traditional Chinese medicine but also a health food. In addition, kudzu is widely distributed in my country, with high yield and rich resources, and kudzu is a fast-growing plant suitable for large-scale planting, and it is a plant resource that can be continuously developed and utilized. But for a long time, kudzu root has only been used as a raw material for extracting kudzu root starch, and its processing method is also very primitive, resulting in a great waste of resources. The main effective chemical components of kudzu root are the total flavonoids and puerarin of kudzu root. At present, the total flavonoids and puerarin of kudzu root have significant effects in enhancing immunity, preventi...
