Abstract
The present invention provides a kind of extracting method that viscid germander herb is fixed, the fixed preparation method of the viscid germander herb includes the following steps：(1) viscid germander herb Chinese herbal medicine is taken, physical crushing is carried out；(2) it is flowed back, is stripped with ethanol solution；(3) extract is taken to be concentrated；(4) concentrate is eluted using sephadex LH-20 pillar, methanol；(5) condensing crystallizing is carried out to eluent；It obtains viscid germander herb and determines extract；Reach 98.72% using the fixed purity of viscid germander herb made from this method；Moreover, extraction process of the present invention is simple, elution is carried out using sephadex LH-20 column and replaces carrying out elution processing using traditional silicagel column in existing technology, substantially increases elution efficiency, and reduce solvent usage, more saving cost.
Description
Technical field
The present invention relates to effective ingredients in plant extracts, and in particular to the extracting method fixed to viscid germander herb.
Background technique
Viscid germander herb is fixed, English name：tencvidin；It is mainly extracted from viscid germander herb, existing extracting mode is using tradition
Silicagel column chromatographed, the fixed purity of viscid germander herb for needing to consume a large amount of organic solvent, and efficiency is extremely low, and obtaining
It is not high.Can be simple and direct the invention is intended to develop one kind, consumption solvent is few, and the high viscid germander herb of product purity determines extracting method.
Summary of the invention
In order to solve to need to consume a large amount of using traditional silica gel column chromatography during existing viscid germander herb extracts surely
Solvent, and extraction process is complicated, and the not high problem of purification purity, the present invention provides a kind of easy-to-use viscid germander herbs to mention surely
Take method；Including following content：
A kind of extracting method that viscid germander herb is fixed, the fixed extracting method of the viscid germander herb include the following steps：
(1) viscid germander herb Chinese herbal medicine is taken, physical crushing is carried out；
(2) it is flowed back, is stripped with ethanol solution；
(3) extract is taken to be concentrated；
(4) concentrate is eluted using sephadex LH-20 pillar, methanol,；
(5) condensing crystallizing is carried out to eluent；It obtains viscid germander herb and determines extract.
Preferably, the ethanol solution used in the fixed extracting method step (2) of the viscid germander herb is 3 liter 95% of second
Alcoholic solution.
Preferably, the fixed extracting method of the viscid germander herb includes the following steps：
(1) 1 kilogram of viscid germander herb Chinese herbal medicine is taken, physical crushing is carried out；
(2) it is flowed back, is extracted 2 times with 3 liter 95% of ethanol solution；
(3) extract is taken to be concentrated to dryness；
(4) concentrate is used into sephadex LH-20【500 grams】, 7 centimetres of column diameter (diameter), 2 liters of anhydrous methanols carry out
Elution,；
(5) it collects eluent part of the purity greater than 98% and carries out condensing crystallizing, obtain viscid germander herb and determine extract.
Reach 98.72% using the fixed purity of viscid germander herb made from this method；Moreover, extraction process of the present invention is simple, adopt
With using sephadex LH-20【500 grams】, 7 centimetres of columns of column diameter (diameter) carry out elution replace existing technology in using tradition
Silicagel column carries out elution processing, substantially increases elution efficiency, and reduce solvent usage, more saving cost.
Specific embodiment
The present invention will be further described in detail below with reference to the embodiments, following embodiment be explanation of the invention and
The invention is not limited to following embodiments.
Embodiment：
A kind of extracting method that viscid germander herb is fixed is present embodiments provided, is included the following steps：
