| Abstract: | Objective： To develop an RP - HPLC method to determiine content of Magnolol in bark of Mulina （ Manglietiafordiana Oliv. ）.Methods： RP-HPLC method and irchrom Cls （200 × 4.6mm,5μn） was used. The mobile phase consisted of CH3CN - 0.5 % H3PO4 solution （50： 50） and the flow rate was 1.0mL·min^-1. The UV detection wavelength was 290nm. Column temperature：30℃. Results：The linear range of determination of Magnolol was 0.05896 - 5. 896μg, r = 0. 9999; the sample solution was stable within 24h, the precision in a day was good, RSD = 0.82 % ; the average recovery results of Magnolol were 92.28%, RSD 为 3.3% （n = 9）. Conclusion： This methods was good specialty and precision to determine content of Magnolol in bark of Mulina, rsults were accurate and credible. |
