Abstract: : Aurantio-obtusin,rutin and quercetin were separated on Gemini C18 RP-column(4.6 mm×250 mm,5 μm),the flow rate was 1.0 mL/min,column temperature was 40 ℃. The detection wavelength was set at 370 nm for rutin’s detection in the first 20 minutes,and then changed into 280 nm for the other two ingredients’s detection in 20~30 minutes. The injection volume was 20 μL,with methyl alcohol as the mobile phase A and water as mobile phase B. Results showed that aurantio-obtusin,rutin and quercetin showed good linear relationships in the range of 1.977 2 to 98.860 0 μg/mL(R2=0.999 7),1.958 0 to 97.900 0 μg/mL(R2=0.999 6)and 2.283 6 to 114.18 μg/mL(R2=0.999 6). Their average recovery rates were 98.81% with RSD of 2.0%,98.16% with RSD of 2.2% and 100.44% with RSD of 3.0%. By measurement ,the content of aurantio-obtusin,rutin and quercetin in lipid-lowering Chinese medicines were 0.053 2 mg/g with RSD of 1.36%,0.847 0 mg/g with RSD of 0.65%,and 0.040 9 mg/g with RSD of 0.80%. The method is simple,precise,stable,reproducible,and it can be used for the quality control of lipid-lowering Chinese medicines.

Key words: HPLC, aurantio-obtusin, rutin, quercetin, lipid-lowering Chinese medicines
