Objective To investigate the solubility and stability of magnolol in Hank′s balanced salt solution(HBSS),grounding for its absorption and metabolism.Methods The concentration of magnolol was determined by RP-HPLC.PH、temperature and light were examined on the solubility and stability of magnolol.Results The linear calibration curve of magnolol in methanol was fitted to be Y=4374X-2207.7(r=0.999 9) in the concentration range of 8-200 μmol/L and the detection limit was 0.4 μmol/L with required precision and st...
