ABSTRACT
【Objective】 To assay the naringenin content in different medicinal materials of Exocarpium Citri Grandis (ECG). 【Methods】 High performance liquid chromatography (HPLC) was applied to determine the naringenin content in different medicinal materials of ECG. The chromatographic conditions were gradient elution being performed with methanol as mobile phase A and water - acetic acid (61 4) as mobile phase B, flowing rate being 1.0 mL/min; detecting wavelength at 283 nm. 【Results】 In the rage of 0.088~0.880 ?g, naringenin showed a good linearity with the chromatographic peak area, r=0.9999, average recovery rate was 95.49% and RSD=2.00% (n=5). The naringenin content in 23 different samples of ECG was in the range of 0.1~1.0 mg?g~(-1). 【Conclusion】 It is the first time to establish the HPLC method for the determination of naringenin content in ECG and the method is accurate and reproducible. Naringenin content in varieties of ECG is stable and the difference of naringenin content between Citrus grandis Osbeck. Var. tomentosa Hort. and Citrus grandis (L.) Osbeck is not significant.
