A method for simultaneous extraction of anthraquinone and polysaccharide in Morinda officinalis

Abstract

The invention belongs to the field of processing of Chinese herbal medicines, and particularly relates to a method for synchronously extracting anthraquinone and polysaccharide in morinda officinalis. According to the invention, morinda officinalis whole-root dry powder is screened with a 80-mesh sieve, then an ethanol solution with volume fraction of 37% is added according to the material-solution ratio of 1g:37ml for extraction, with the extraction temperature of 60 DEG C, and the extraction time of 77min, then synchronously obtaining an extraction solution containing anthraquinone and polysaccharide, and finally carrying out separation and purification to obtain anthraquinone and polysaccharide respectively. In the conditions, the measured highest extraction rate of anthraquinone in morinda officinalis can reach 85%, and the extraction rate of polysaccharide is 70%. The process is relatively high in extraction rate of anthraquinone and polysaccharide in morinda officinalis in synchronous extraction, and can greatly improve the material utilization rate, shorten the extraction time, reduce the extraction cost, and reduce reagent dosage in a large scale, thus realizing environment-friendly and synchronous extraction of effective components.

Description

technical field [0001] The invention belongs to the processing field of Chinese herbal medicines, and in particular relates to a method for synchronously extracting anthraquinone and polysaccharides from Morinda officinalis. Background technique [0002] Morinda( Morinda officinalis How ), also known as Jichangfeng, Triangle Vine, Corn Vine, etc., is a perennial vine of Rubiaceae, 3-13cm long, 1.5-5cm wide, with short acuminate front ends and blunt or round bases. The dry root of Morinda officinalis is flat cylindrical, slightly curved. Rich in tropical and subtropical regions such as Fujian, Guangdong, Hainan, and Guangxi. Born in sparse mountains, dense forests and shrubs, often climbing on shrubs or tree trunks, there are also introduced species. Medicinal plants, mainly used to treat impotence and nocturnal emission, uterine cold and infertility, irregular menstruation, cold and pain in the lower abdomen, rheumatic arthralgia, muscle and bone flaccidity. Its chemical...

AI Technical Summary

Problems solved by technology

[0003] In the past industrial extraction, anthraquinone and polysaccharides were extracted from Morinda officinalis separately, so the cycle is very long, the demand for materials is large, and the amount of chemical reagents is large, which is contrary to the purpose of energy saving and emission reduction.
