Abstract:
This study is to develop a sensitive method by using reversed-phase high performance liquid chromatography coupled with UV detector (HPLC-UV) to simultaneously determine four bioactive compounds, iriflophenone 3-C-beta-D-glucoside, iriflophenone 3,5-C-beta-D-diglucoside, mangiferin, and iriflophenone 2-O-alpha-L-rhamnoside in the leaves of Aquilaria sinensis. An Agilent Zorbax SB-C, column (4, 6 mm x 250 mm, 5 microm) was used, and the gradient elution was performed with mobile phase of 0.1% aqueous phosphoric acid and acetonitrile at a flow rate of 1 mL x min(-1). The detection wavelength was 280 nm, and the column temperature was 25 degrees C. The four marker compounds were well separated with good linearity (R2 > 0.9990), precision, stability and repeatabili y. The-recovery rates were in the range of 98.80%-101.39%. For 15 branch of the leaves, the contents of iriflophenone 3-C-beta-D-gluoside, iriflophenone 3,5-C-beta-D-diglucoside, mangiferin, and iriflophenone 2-O-alpha-L-rhamnoside were between 0.41-14.48, 0.72-3.85, 4.30-29.07, 0.24-5.06 mg, respectivley. This method is precise, accurate and reliable, which provides an efficient way for the quality control of the leaves of A. sinensis. This will promote the comprehensive usage of this plant.
