The content of element of the root of kudzu vine in health capsule measures arte
From;    Author:Stand originally

[character] this tasting for capsule agent, content content comes for beige Brown powder; Energy of life is tiny, taste is bitter.
[differentiate] (1) takes this tasting content content 3g, add water 50ml, immerse 2 hours, filtration, filtrate adds polyamide 10g, agitate divide evenly, immerse 40 minutes, bend goes aqueous solution, bathe cleanse polyamide is washed to water fluid is close colorless, filtration, abandon go filtrate, filter broken bits adds acetone 30ml, immerse 12 hours, filtration, filtrate brandish goes acetone, residual add methanol 2ml liquefy, as taste solution for trying. Take element of the root of kudzu vine additionally to contrast article, add methanol to make the solution that contains 1mg into every 1ml, as contrast taste solution. Take way of layer color atlas (appendix Ⅵ B) experiment, absorb two kinds of afore-mentioned solution L of each 5 μ , nod respectively at same with carboxyl sodium is methylic cellulose the silica gel G of bind agent on layer board, with chloroform - ester of acetic acid second - methanol - 2 ethylamine - water (13:20:14:1: 5) to develop an agent, spread out, take out, air, buy ultraviolet light (the postmortem below 365nm) . In tasting color atlas for trying, in with contrast taste color atlas corresponding locally, show the fluorescent spot of same color.
(2) takes Song Xie to contrast medicinal material 5g, add water 100ml, boil 30 minutes, put cold, filtration, differentiate 〕 by 〔 (1) next preparation methods that taste solution for trying, from " add polyamide 10g " have the operation that be the same as a law, make solution of contrast medicinal material. Take way of layer color atlas (appendix Ⅵ B) experiment, absorb [differentiate] (1) fall to taste solution to reach afore-mentioned contrasting for trying medicinal material solution L of each 10 μ , nod respectively at same with carboxyl sodium is methylic cellulose the silica gel G of bind agent on layer board, with chloroform - ester of acetic acid second - formic acid (7:3: 0.5) is develop an agent, spread out, take out, air, after be being fumed in buy ammonia steam, buy ultraviolet light (the postmortem below 365nm) . In tasting color atlas for trying, in with contrast medicinal material color atlas is corresponding locally, show the fluorescent spot of same color.
[examination] should accord with capsule agent each provision that next concerning (appendix Ⅰ L) .
[content determines] according to law of color atlas of concentrated juice photograph (appendix Ⅵ D) determine.
Color atlas condition and systematic applicability experiment use silica gel of bond of alkyl of 18 alkyl silicon to be filler; With methanol - acetic acid - water (25:3: 72) for photograph of going from place to place; Detect wavelengh is 250nm. Theory board number presses computation of peak of element of the root of kudzu vine to answer not under 2500.
Contrast the preparation that tastes solution is taken in 105 ℃ dry contrast to the element of the root of kudzu vine of constant weight article right amount, nicety says to decide, add 50% alcohol to make the solution that contains 40 μ G into every 1ml, get namely.
