total flavonoids and volatile oil in different batches of Citrus aurantium and evaluate the quality. Method: The naringin and neohesperidin were detected by HPLC. The analytical column was a Diamonsil C18 (4.6 mm×250 mm
5 μm). A mixture of acetonitrile-water (pH was adjusted to 3.0 by phosphoric acid) (20: 80) was used as the mobile phase with the flow rate at 1 mL·min-1. The detection wavelength was set at 283 nm. The column temperature was set at 30 ℃. The UV spectrophotometry for the determination of total flavonoids is as follows: detection wavelength was at 283 nm
and the reference substance was naringin. The volatile oil was extracted by steam distillation. Topsis was employed for evaluating quality with the content of naringin
neohesperidin
total flavonoids and volatile oil. Result: The naringin
neohesperidin
total flavonoids and volatile oil were in the ranges of 0%-6.12%
0%-4.55%
6.96%-18.99% and 0.2%-2.0% (mL·g-1) respectively. The quality difference of the samples was large. Conclusion: The content difference of the naringin
neohesperidin
total flavonoids and volatile oil in 17 different batches of C. aurantium was large. The content of naringin and neohesperidin in 6 batches of C. aurantium comes up with 〈Chinese Pharmacopoeia 2010〉.The quality evaluation method was feasible.
