Abstract
The invention relates to a field of plant extracting technology, in particular to a technique for extracting total saponins of tribulus from herba tribuli, which provides a technique for extracting total saponins of tribulus from herba tribuli, in order to solve the problems in the prior art that the raw material resources are limited and that the content of total saponins is low. The technique comprises the following steps in turn: (I) cutting the herba tribuli into short segments (0.5-1cm) and then alcohol extracting and concentrating, placing the concentrated solution in a low temperature of 4 DEG C or so for 12 to 48 hours, filtrating; (II) adding water into the filtrate until each 1ml contains 0.5g original medicinal material, passing a well treated nonpolar macroporous adsorbing resin with a velocity of flow of 2-5BV/h to absorb for 2-3 times, eluting with water until the effluent is of no color; (III) then eluting with 10-30 percent of ethanol until the effluent is of no color, concentrating and drying. Through the modern research, a preparation is finally acquired through extracting and purifying with herba tribuli as raw material. Compared with the traditional drug intake behavior, the technique has wide medicinal material resources, which in deed realizes the principle of changing waste into valuables.
Description
Affiliated technical field:
The present invention relates to technical field of plant extraction, be specifically related to a kind of technology of utilizing tribulus whole grass to extract total saponins of tribulus.
Technical background:
Fructus Tribuli has another name called Fructus Atriplicis Sibiricae, Fructus Tribuli, hard Fructus Tribuli.Nature and flavor suffering, hardship, tepor, slightly poisonous, go into liver, lung meridian, have diffusing wind, make eye bright, the effect of the therapeutic method to keep the adverse QI flowing downwards, promoting the circulation of blood, the kidney invigorating and essence nourishing.Medicinal part commonly used in the Chinese medicine Fructus Tribuli is its fruit, and its extract comprises compositions such as Fructus Tribuli steroidal saponin, flavone, polysaccharide and alkaloid.The total saponins that extracts in the Fructus Tribuli fruit (content about about 40%) is mainly used in the treatment cardiovascular and cerebrovascular disease clinically, as present Xinnaotong capsule for treating blood vessel of heart and brain or Xinnao Shutong sheet etc.The total saponins that extracts from Fructus Tribuli mainly comprises spirostanol saponin (spirostanol) and furostanol (furostanol) two classes, and the spiral shell sterol content is higher, and polarity is little, easily crystallization, and its chemical compound is mainly used in antifungal application; The furan sterol content is lower, and water solublity is bigger, is difficult for crystallization, through pharmacological testing and effect experiment proof resisting cardiovascular is had tangible prevention and therapeutical effect.
Narrower because of Fructus Tribuli fruit source, and pluck, handle trouble, therefore the utilization to its herb becomes the problem that pharmaceuticals industry is paid close attention to.But find in the research that because of comprising more ester soluble components such as chlorophyll in the puncturevine herb, therefore the content of total saponins is lower in its extract.
Summary of the invention:
The present invention will provide a kind of technology of utilizing tribulus whole grass to extract total saponins of tribulus, to overcome the lower problem of content of the raw material resources finite sum total saponins that prior art exists.
For overcoming the problem that prior art exists, the invention provides a kind of technology of utilizing tribulus whole grass to extract total saponins of tribulus, comprise the steps: successively
(1) get puncturevine herb, be cut into short section (0.5～1cm), alcohol extraction, concentrate, concentrated solution low temperature (about 4 ℃) left standstill 12～48 hours, filtered;
(2) filtrate adds water to every 1ml and contains crude drug 0.5g, and by the nonpolar macroporous adsorption resin absorption handled well 2～3 times, it is colourless that water is eluted to effluent with 2～5BV/h flow velocity;
(3) reuse 10～30% ethanol elutions are to colourless, be eluted to 2～5BV/h flow velocity with 4～7BV60～90% ethanol then colourless, collection 60～90% ethanol elution.(0.085Mpa) being evaporated to relative density is 1.25～1.30 extractum (25 ℃ of surveys), and (0.085Mpa) to do pulverize, cross 100 mesh sieves, promptly get of the present invention extract in 60 ℃ by drying under reduced pressure for extractum in 50 ℃.
In the above-mentioned steps (): add 5～10 times of amount 50～90% alcohol reflux 2～5 times during alcohol extraction, each 1～3 hour, filter, filtrate merges, and (0.085Mpa) is evaporated to nothing alcohol flavor at 40～60 ℃.
The resin that above-mentioned steps (two) is adopted is AB-8.Effect is better.
The resin that above-mentioned steps (two) is adopted can also be the nonpolar macroporous adsorption resin of D101 macroporous adsorbent resin or HPD series.
By modern study, we adopt puncturevine herb is that raw material is through extracting purification and it finally being made preparation.Compare with traditional medication custom, its crude drug source is wider, and really having accomplished turns waste into wealth.In extraction process, increased the stand at low temperature step especially, this step can effectively be removed ester soluble components such as chlorophyll, and the content of total saponins is higher in the extract.And this method is simple to operation, can satisfy industrial production requirement.
The specific embodiment:
