Abstract:
Objective To establish an HPLC method for simultaneous determination of Isoquercitrin and astragalin in Moringa oleifera leaves prescription. Methods By using HPLC method with Cosmosil-C18 column (4.6 mm × 250 mm, 5 μm) and the column temperature was 40 degrees Celsius, the mobile phase contains a 0.1%phosphoric acid in water(A) and acetonitrile(B), the detection wavelength was set at 350nm by UV detector and the flow rate was 1.3 ml/min. Results The Isoquercitrin and astragalin was better separated in 30 minutes, and Isoquercitrin had a good linear correlation at the range of 0.24-4.73 μg, while astragalin was 0.11-2.19 μg, the average spiked recoveries of isoquercetin and astragalin were 99.09% (RSD=0.60%) and 99.08% (RSD=1.37%), respectively. Conclusions The proposed method is simple,accurate,and repeatable and can be used for quality control as well as a powerful tool to evaluate the processing of Moringa oleifera leaves. It can provide the reference basis and data support for the determination of content of Moringa oleifera health products.
