A colorimetric method for the determination of antimony in the range 0.1 to 3.0μg per milliliter blood is described. The time needed for the destruction of organic matter is shortened to 8—12 minutes. The proposed method is as follows: Accurately transfer 1 ml of blood sample to a hard glass test tube (25×150 mm.), to which 1 ml of conc. HNO_3 is then added. Heat gently with a small flame till the solution changes to amber color. Add 0.5 ml conc. H_2SO_4 and heat again carefully until dense white fume is evolved....

If the solution is not clear, add a few more drops of HNO_3 and heat repeatedly till a clear colorless solution is obtained. Cool, add 1 ml NaCl solution and 0.5 ml NaNO_2 solution, shake for 2 minutes, then add 1 ml of urea solution. Transfer the mixture to a separatory funnel containing 10.0 ml benzene. Wash the test tube with three portions (5 ml) of distilled water, add 10 drops of malachite green reagent solution and shake the mixture immediately for 5 minutes. Separate the benzene layer in a centrifuge tube and centrifuge 3 minutes to separate the suspended droplets of water. Transfer the benzene solution into a 10 cm cell and measure the extinction with an Ilford 607 filter, using benzene as blank.

Three methods for the preparation of berberine citrate are described. (1) About 100 g of berberine hydrochloride and 200 ml of water were shaken together, and 300 ml of 30% NaOH was added; shaking was continued until the colour of crystal was obviously changed. The mixture was allowed to stand for a short time; the supernatant should be colourless. Then the free base was collected by filtration,washed with water until free from NaOH and then with a little alcohol. The ppt. was transferred into another bottle,...

(1) About 100 g of berberine hydrochloride and 200 ml of water were shaken together, and 300 ml of 30% NaOH was added; shaking was continued until the colour of crystal was obviously changed. The mixture was allowed to stand for a short time; the supernatant should be colourless. Then the free base was collected by filtration,washed with water until free from NaOH and then with a little alcohol. The ppt. was transferred into another bottle, 11 of alcohol and 120—150 g of citric acid were added. The mixture was refluxed until complete dissolution; after cooling, the crude product was collected in a Buchner funnel, and recrystallized from 70% alcohol. The yield is about60—70%. (2) About 100 g of berberine hydrochloride, 100 ml of acetone, and 400 ml H_2O. Were heated together to 60—70℃, and with shaking, 50 ml of 50% NaOH was added. The mixture was kept at this temperature for 1—2 hours, cooled, and the berberineacetone was collected in a Buchner funnel, washed with water until the washings was colourless. The ppt. was transferred into a 21 bottle, 1500 ml 70% alcohol and 70 g of citric acid were added. The mixture was refluxed until complete dissolution, cooled, and the product was collected and purified from 70% alcohol. The yield is 85—95%. The berbetine citrate obtained is in pale yellow needles, m.p. 209—211℃. (3) About 1 kg of berberine hydrochloride was added to 12 liter of 70% alcohol and 1.2—1.5 kg citric acid. The mixture was Heated to boiling and 500 ml of 50% sodium hydroxide was added. It was kept at this temperature for 1—2 hours. After cooling, the crystalline product was collected and purified from 70% alcohol. The yield is 85—90%. The method can also be adapted for the preparation of berbetine sulphate from its hydrochloride. Two methods for the assay of berberine citrate are also described.

Paris' method for the determination of anthraquinone content of plant drug has been studied. Through the analysis of several drugs, including Rheum palmatum L., Cassia tora L., and Polygonum multiflorum Thunb., more favorable analytical conditions were established; the free and combined anthtaqiiinone contents of a plant drug could thus be determined as follows: Free anthraquinones: 0.1—l.0g finely powdered sample is accurately weighed and extracted with chloroform in a Soxhlet apparatus. The chloroform extract is shaken with successive portions of 5% sodium hydroxide-2% ammonia mixture in a separatory funnel until the alkali solution is colourless. The alkali extracts are combined and diluted to a certain volume. If the solution becomes turbid, it is filtered through a sintered glass filter and the filtrate collected for colorimetric determination in a photometer with a 490 mμ filter. The result is calculated from a calibration curve obtained with 1,8-dihydroxyanthraquinone. The extraction with the mixed alkali solution and the colorimetric measurements must be done in a shaded room to prevent the decomposition of the coloured solution by light. Combined anthraquinones: 0.05—0.1g finely powdered sample is accurately weighed and placed in a 100 ml conical flask, 30 ml of 5 N sulphuric acid are added, and the mixture is refluxed for two hours to hydrolyse the combined anthraquinones. The flask is cooled, then refluxed with 30 ml chloroform for one hour. The latter is removed with a dropper, replaced by a fresh portion of 20 ml chloroform and refluxed for 20 minutes. This extraction process is repeated until anthraquinones are exhausted. The chloroform extracts are combined, washed with small portions of distilled water, extracted with the mixed alkali solution as above, and determined colorimetrically. This gives the total anthraquinone content, from which is subtracted the amount of free anthraquinones in order to get the percentage of combined anthraquinones.

本文在Paris等人所报导方法的基础上,研究了蒽醌显色后的稳定性情况,以及用酸水解结合蒽醌与提取的条件,进而分析了几种植物药中游离蒽醌与结合蒽醌的含量,认为方法尚可应用.游离蒽醌系将生药样品在Soxhlet提取器内用氯仿提取,提取液用5%NaOH-2%NH_40H提取后比色,以1,8-二羟蒽醌为标准;结合蒽醌则先用5N硫酸水解,回流2小时,再加氯仿回流提取数次,至提尽为止,合并氯仿液,同上以碱液提取后比色测定.
