Hydrocortisone butyrate ointment
- Hydrocortisone butyrate ointment is a white cream. Used for
- Hydrocortisone butyrate ointment
- English name: Hydrocortisone Butyrate
- Latin name: unguentum Hydrocortisone Butyras
- Product name:
- According to high performance liquid chromatography (Appendix V D). Chromatographic conditions and system suitability tests use octadecylsilane bonded silica as a filler, water-acetonitrile-glacial acetic acid (55: 45: 0.5) as the mobile phase; the detection wavelength is 240nm. The number of theoretical plates calculated from the peak of hydrocortisone butyrate should not be less than 1500, and the resolution of the peak of hydrocortisone butyrate from the internal standard substance peak should meet the requirements. Preparation of the internal standard solution Methyltestosterone was added to make a solution containing 0.18 mg per 1 ml of methanol. Assay method: Take an appropriate amount of hydrocortisone butyrate reference, accurately weigh, dissolve with methanol and quantitatively dilute to make a solution containing 0.26mg per 1ml; accurately measure 5ml each of this solution and the internal standard solution, and place in a 50ml measuring bottle Medium, dilute to the mark with methanol, shake well, take 20l into the liquid chromatograph, record the chromatogram; also take an appropriate amount of this product (approximately 1.3mg of hydrocortisone butyrate), accurately weigh, add 15ml of methanol, Heat in a 50 water bath, stir to dissolve the hydrocortisone butyrate, cool to room temperature, add 5ml of the internal standard solution precisely, dilute to 50ml with methanol, shake well, place in an ice bath and cool for more than 2 hours. Filter and place at room temperature. Take 20l of the filtrate and inject it into the liquid chromatograph. Record the chromatogram and calculate the peak area according to the internal standard method.
