Abstract:
AIM : To establish a HPLC method for simultaneous determination of rutin and naringenin-7-o-glucoside in Lysimachia clethroide Duby.METHODS: Using Diamonsil C_(18) (4.6 mm×250 mm,5 μm) as analytical column.The mobile phase consisted of acetonitrile (A) and 0.1% phosphoric acid ( B ) with gradient elution : 0～18rain,83%～80% B; 18～30 min,80%～86% B.The detection wavelength of rutin and naringenin-7-o-glucoside was at 254 nm and 281 nm,respectively.The flow rate was 1.0 mL/min; Column temperature was at 35 ℃.RESULTS: A better separating effect was obtained with the HPLC gradient elution method.The linear calibration curve of rutin and naringenin-7-o-glucoside were obtained in the concentration range of 1.00～48.00 μg/mL( r =0.999 3 ) and 0.64 ～ 40.72 μg/mL( r = 0.999 8 ),respectively.CONCLUSION : The HPLC method is accurate,simple and can be used to determine the contents of rutin and naringenin-7-o-glucoside in Lysimachia clethroide Duby simultaneously.
