20 (R)-ginseng sapoglycoside Rg 3 medicinal soluble complex and preparation methoies
Technical field the present invention relates to a kind of ginsenoside's medicinal soluble complex and preparation method thereof.
Background technology ginsenoside Rg3 is a kind of tetracyclic triterpenes saponin compound that is present in the Radix Ginseng, molecular weight is 784.32, it exists with 20 (R)-ginsenoside Rg3s and two kinds of optical isomer forms of 20 (s)-ginsenoside Rg3s again, wherein 20 (R)-ginsenoside Rg3 chemical property are stable, water insoluble, and 20 (s)-ginsenoside Rg3 unstable chemcial properties are soluble in water, and their structural formula is respectively:
20 (R)-ginsenoside Rg3 20 (S)-ginsenoside Rg3s
The molecular structural formula molecular structural formula
It is found that, 20 (R)-ginsenoside Rg3s have stronger inhibition tumor and metastasis effect, but it is again a kind of almost water-fast material, so the bioavailability of its oral formulations is very low, greatly limit the performance of its clinical drug effect, also limited the parenterai administration approach simultaneously.
For making 20 (R)-ginsenoside Rg3s water-soluble, people study this, as on January 29th, 2003 Gazette of Patent for Invention disclosed a kind of<panaxoside Rg 3 hydroxypropyl-beta-cyclodextrin inclusions and preparation and preparation method (application number 01119929.6) its to the effect that: the hydroxypropyl-beta-cyclodextrin inclusion of panaxoside Rg 3, it is made up of by following weight ratio following raw material, i.e. the ginsenoside: HP-=1:1~200; Its preparation method is that (1) is dissolved in panaxoside Rg 3 in the organic solvent, (2) HP-is soluble in water, (3) under strong agitation, panaxoside Rg 3 solution slowly are added drop-wise in the aqueous solution that contains HP-, all adding the back continues to stir 2~24 hours, use 0.45 μ m filtering with microporous membrane, filtrate is concentrated, eliminate organic solvent, adding injection water dissolves again, cross 0.22 μ m film, the filtrate lyophilization, the white powder that must loosen is ginsenoside's clathrate.
Its weak point is: (1) clathrate is in preparation process, its reactant liquor is recycled to 1/3 o'clock of original volume, still have more organic solvent residual after measured, and lyophilization is invalid to removing residual solvent, thereby this clathrate powder is used to prepare the limit standard that injection is difficult to meet the injection residual solvent.(2) clathrate is in preparation process, because the existence of residual organic solvent, help panaxoside Rg 3 and HP-to form water-soluble clathrate with the ratio of 1:1~200, if residual organic solvent is really eliminated, then in the aforementioned proportion scope, can not form stable clathrate soluble in water, panaxoside Rg 3 can be separated out precipitation very soon from its clathrate aqueous solution, make this clathrate can not be used to prepare injection.(3) panaxoside Rg 3 can not all form clathrate, and utilization rate is 86% only, and the productive rate reduction and the production cost of injection are obviously increased.
Summary of the invention the object of the present invention is to provide 20 (R)-ginseng sapoglycoside Rg 3 medicinal soluble complex and the preparation methoies that a kind of product cost is low, easily be absorbed by the body.
Main material of the present invention (abbreviation major ingredient) is 20 (R)-ginsenoside Rg3s, and auxiliary material (abbreviation adjuvant) is sodium lauryl sulphate (magnesium); The weight ratio of above-mentioned major ingredient and adjuvant is 1:4~50.
The preparation method of 20 (R)-ginseng sapoglycoside Rg 3 medicinal soluble complex:
(1) 20 (R)-ginsenoside Rg3s are soluble in water, make ginsenoside's suspension of 0.01~5%,
(2) sodium lauryl sulphate (magnesium) is soluble in water, make 0.1~5% aqueous solution,
(3) under 1~100 ℃ of condition, stir sodium lauryl sulphate (magnesium) solution and add ginsenoside's suspension, wherein 20 (R)-ginsenoside Rg3s: sodium lauryl sulphate (magnesium)=1:4~50, stirred 1-300 minute,
(4) decompression and solvent recovery is extremely an amount of, drying, and the gained powder is 20 (R)-ginseng sapoglycoside Rg 3 medicinal soluble complex, and 20 (R)-ginsenoside Rg3s' content is 2~20% in this medicinal soluble complex.
