Abstract
OBJECTIVE To determine the extraction of 10 kinds of antioxidants, BHT-COOH, BHT-CHO, 2,4-DTB, BHT-Q, BHT, antioxidant 3114, antioxidant 1010, antioxidant 330, antioxidant 1076, and antioxidant 168, in 24 batches of halogenated butyl rubber stopper for packaging of amoxicillin sodium clavulanate potassium for injection by HPLC method, and detect the migration of the above antioxidants in 24 batches of halogenated butyl rubber stopper and 43 batches of amoxicillin sodium clavulanate potassium for injection by UPLC/Orbitrap HRMS as additional verification. METHODS HPLC method was established to determine the above components. The determination was performed by using SHIMADZU Shim-pack GIST C18 column(4.6 mm×250 mm, 5 μm)with mobile phase consisting of water (A)-methanol (B)-acetonitrile (C) gradient elution at the flow rate of 1 mL·min-1. The detection wavelength was set at 220 nm,and the column temperature was maintained at 25 ℃. UPLC/Orbitrap HRMS method consisted of Thermo Hypersil GOLD column(2.1 mm×100 mm, 1.9 μm)with mobile phase consisting of water (A)-methanol (B) gradient elution at the flow rate of 1 mL·min-1, 220 nm detection wavelength, 25 ℃ column temperature, and an ion source in the electrospray ion source(ESI). Positive and negative ion ionization (ESI+, ESI-) mode was used for detection,the mass number scanning range was m/z 150-1 500, and the injection volume was 1 μL. RESULTS Under the established liquid phase conditions,the resolution of each component was good,and the resolution was greater than 2.0. The precision,repeatability,recovery rate, and stability were in line with the relevant requirements. The linear range was 1.02-233.20 μg·mL-1(r≥0.999 8). The detection limits of the 10 antioxidants were 0.06-3.90 μg·mL-1. The limits of quantification were 0.18-11.72 μg·mL-1. The migration of the above antioxidants in the rubber stopper and the drug was verified by UHPLC/Orbitrap HRMS method. Seven kinds of antioxidants were detected in all halogenated butyl rubber stoppers, respectively, in addition to antioxidant BHT-CHO, BHT-Q and antioxidant 168. Antioxidant BHT was detected in 9 batches of the drug, and antioxidant 330 was detected in 4 batches. CONCLUSION This method can be used to study the extraction and migration of the above 10 kinds of antioxidants in halogenated butyl rubber stopper for packaging of amoxicillin sodium clavulanate potassium for injection.
