Liquid chromatographic method for the analysis of two plant based insecticide synergists dillapiole and dihydrodillapiole.
A reversed-phase LC method for the determination of two plant based insecticide synergists dillapiole (5-allyl 6,7-dimethoxy 1,3-benzodioxole) and dihydrodillapiole (5-n-propyl 6,7-dimethoxy-1,3-benzodioxole) is reported. The resolution of dillapiole and dihydrodillapiole has been achieved on RP-18 column using methanol-water (90:10, v/v) as mobile phase and a photodiode array detector at 207 nm. The response was linear in the range of 25-250 microg. The developed isocratic RP-LC method was validated for specificity, linearity, precision, and accuracy. It has been applied for individual or simultaneous detection, monitoring and quantification of dillapiole and dihydrodillapiole from treated French bean Phaseolus sp.
