Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with specific embodiments.

[0017] Referring to shown in Fig. 1, the extraction method of Eclipta saponins compound of the present invention, its step is:

[0018] (1), preparation of Eclipta crude extract: Eclipta crude powder, using 70% ethanol microwave extraction for 3 times, recovering ethanol in two steps, recovering to 1 / 2 of the total volume for the first time, and standing for 24 hours , can remove pigment and some fat-soluble impurities. It is recovered to 1 / 4 of the total volume for the second time to obtain the extract concentrate of Eclipta chinensis.

[0019] (2), Utilize foam countercurrent chromatography (Foam CCC) to prepare the crude product of total saponins of Eclipta chinensis: dilute the above concentrate with water, put it in a foam countercurrent chromatograph, extract continuously with n-butanol, collect the foam outflow part, and react to Libermann until negative....

Abstract

The invention relates to an extracting method of steroid saponins of yerbadetajo, which comprises the following steps: firstly, preparation of coarse extract of yerbadetajo: extracting coarse yerbadetajo powder for 3 times with microwaves by using 70 percent ethanol, recovering the ethanol by two steps to obtain concentrated yerbadetajo extract solution; secondly, preparation of total saponins coarse product of yerbadetajo by adopting a froth counter current chromatography: adding water to dilute the concentrated yerbadetajo extract solution, placing the diluted concentrated yerbadetajo extract solution into a froth counter current chromatographic instrument, continuously extracting by using normal butanol, collecting outflow froth until Libermann reaction is negative, combining the obtained normal butanol, recovering the normal butanol, and obtaining the total saponins coarse product of yerbadetajo; thirdly, purification of the total saponins of yerbadetajo by utilizing macroporous absorbent resin; fourthly, filtration: filtering the obtained total saponins by using a reverse osmosis membrane, further removing water-soluble impurity to obtain the total saponins with high purity. The invention has the advantages of simple and convenient operation, little environmental pollution, small energy consumption, good environmental protection, high extraction efficiency and the like.

Description

technical field [0001] The invention mainly relates to the technical field of extracting substances from natural plants, in particular to a method for extracting Eclipta saponins. Background technique [0002] With the progress of human social civilization and the rapid development of modern science and technology, human living conditions and living environment are constantly changing. Human health concepts and awareness of the pursuit of quality of life are enhanced, making the connotation of health continue to expand. In the international trend of human returning to nature, all countries in the world have realized the huge market potential of natural plants, and the international market of natural plants is expanding rapidly. According to the report of the World Bank, the world's natural medicine industry will reach 200 billion US dollars in 2008. [0003] Eclipta prostrasta L. is the aerial part of Eclipta prostrasta L., a plant of Compositae. It is mainly used for loos...
