摘要：

A sensitive high-performance liquid chromatographic procedure for the quantitative determination of azadirachting A and estimates of other azadirachtins in insecticidal formulations is described. The procedure utilizes reversed-phase chromatography with detection by UV absorption at 215 nm. The quantitative method described has been found to be accurate to within +/-10% relative between the concentrations of 0.005 and 0.75% (w/w) azadirachtin A in insecticidal formulations of neem kernel extract. The lower limit of detection is 0.001% (w/w).
