This product is 9-[4,6-0-(R)-ethylene-B-D-glucopyranoside; HZ-demethylated white toxin. The C29H32013 content shall be 95.0% to 103.0% based on the water-free content.
take this product, precision weighing, plus three gas methane-methanol (9:1) dissolved and quantitatively diluted to make a solution containing about 5mg per lm l, measured according to law (General rule 0621), the specific rotation is from one 110 ° to one 118 °..
take 0.30g of this product, add dichloromethane-methanol (9:1) mixed solution of 10ml dissolved, the solution should be clear and colorless. In case of color development, it shall not be deeper in comparison with the yellow No. 1 Standard Colorimetric solution (General rules 0901 first method).
take this product, add mixed solvent [acetonitrile-acetate buffer (take sodium acetate 5.44g, dissolve and dilute to 4.0 with water, adjust pH to with glacial acetic acid)(30:70)] dissolve and dilute to prepare a solution containing about 2mg per 1ml, and take an appropriate amount of propyl paraben as a test solution, add a mixed solvent, dissolve and dilute to prepare a solution containing about 0.2mg per 1ml, and take 1ml, in a 200ml measuring flask, 1ml of human test solution was added precisely, diluted to a scale with a mixed solvent, and shaken to obtain a control solution. According to the high performance liquid chromatography (General 0512) test, with phenyl silane bonded silica gel as filler, acetonitrile-salt buffer (20:80) as mobile phase A, acetonitrile-acetate buffer (60:40) was used as mobile phase B; Gradient elution was carried out as follows; Detection wavelength was 254nm. The retention time of the etoposide peak is about 25 minutes, and the degree of separation of the etoposide peak from the propyl paraben peak should be satisfactory. 20ul of the test solution and the control solution were respectively injected into the human liquid chromatograph, and the chromatogram was recorded for 40 minutes.
