Embodiment 1
[0019] Chromatographic conditions: ODS chromatographic column is used; the mobile phase A is acetonitrile-potassium dihydrogen phosphate buffer (5.44g potassium dihydrogen phosphate is dissolved in 900ml water, adjusted to pH 4.5 with 5% phosphoric acid, diluted to 1000ml with water), the volume ratio is 10:90, the mobile phase B was acetonitrile, and the gradient elution program was shown in Table 1. The detection wavelength is 284nm, the flow rate is 1.0ml / min, and the column temperature is 30°C.
[0020] Determination method: Take buprenorphine hydrochloride injection and 5% glucose injection to measure according to the above conditions; take another 5-hydroxymethylfurfural reference substance, weigh it accurately, add water to dissolve and dilute to make a solution containing 10 μg per 1ml , as a reference solution.
[0021] The measurement results show that the retention time of 5-hydroxymethylfurfural is about 4.5min, which is much longer than the dead time of the chrom...
Embodiment 2
[0023] According to the detection conditions of "5-hydroxymethylfurfural" under the item of buprenorphine hydrochloride injection in the Chinese Pharmacopoeia 2010 edition.
[0024] Chromatographic conditions: ODS column is used; mobile phase is methanol-acetonitrile-2% ammonium acetate solution-glacial acetic acid (60:10:40:5); flow rate is 1.0ml / min; detection wavelength is 288nm; column temperature is 30°C .
[0025] Determination method: Take buprenorphine hydrochloride injection and 5% glucose injection to measure according to the above conditions; take another 5-hydroxymethylfurfural reference substance, weigh it accurately, add water to dissolve and dilute to make a solution containing 10 μg per 1ml , as a reference solution.
[0026] The measurement results showed that the retention time of 5-hydroxymethylfurfural was about 3 minutes, which was close to the solvent peak, and the separation was not complete, and other degradation products of glucose were not separated,...
