Authoritative Data Verified Data
15-episomer
take this product, add methylated solution and dilute to make a solution containing about 0.2mg per lml as a test solution; Take 2ml for precision measurement and put it in a 50ml measuring flask, as a control solution, it was diluted to the scale with methanol and shaken. According to the chromatographic conditions under the item of Holter determination, 20 u1 of the test solution and the control solution are respectively injected into the liquid chromatograph, and the chromatogram is recorded to 2 times of the retention time of the main component peak. If there are 15-episomer chromatographic peaks corresponding to those in the test solution for system suitability in the chromatogram of the test solution, the peak area shall not be greater than that of the main peak area of the control solution (4.0%).
loss on drying
take this product, put it in a phosphorus pentoxide dryer, and dry it under reduced pressure for 24 hours. The weight loss shall not exceed 3.0% (General rule 0831).

measured by high performance liquid chromatography (General rule still 12).
chromatographic conditions and system suitability test
with eighteen alkyl silane bonded silica gel as the filler; Methanol-water (70:30) as the mobile phase; The detection wavelength was 202 nm, dissolving and diluting the fermentation broth to make a solution containing about 0.2mg of each 15-episomer and carboprost methyl ester in 1 ml, as the system suitability test solution, taking 20u1 injection human liquid chromatograph, the theoretical plate number is not less than 2000 calculated by the carboprost methyl ester peak, and the separation degree between the 15-episomer peak and the carboprost methyl ester peak should be greater than 1.2.
assay
take an appropriate amount of this product, weigh it accurately, dissolve it with fermentation and dilute it quantitatively to make a solution containing 0.2mg per 1 ml, and use it as a sample solution, and take 20ul for precision measurement, inject into liquid chromatograph, record the chromatogram; Take the carboprost methyl ester reference substance, with the same method, according to the external standard method to calculate the peak area, obtained.
