[Abstract] Objective :To establish a HPLC method to determine the quantitative of physcion in Morinda officinalis from different locations.Methods:Separation column was Agilent C18(4.6×250mm,5μm)with the column temperature of room temperature.The mobile phase composition was methonal-0.1% phosphoric acid (78:22) and the flow rate was 1.0ml/min.The UV detection wavelength was 254nm.Results :A good linearity was obtained in the range of 0.118-1.18μg/mL with r =0.9991.The average recovery was87.12%,and RSD was %(n=6).Conclusion : The content of physcion was vary with the producing area of Morinda officinalis.The method was good for determining physcion in Morinda officinalis.
