Web18.3.4 Analysis, persistence and fate of growth regulators in soils. Analytical procedures are mentioned here for determination of azadirachtin and diflubenzuron, as representatives of growth regulators. Azadirachtin is an isomeric mixture of seven or so tetra-triterpenoids isolated from the seeds of the tropical neem tree. WebMore recently, Biotage flash chromatography for up to 5 g of seed extract has been shown to give higher recoveries of azadirachtin. 395 However, very pure azadirachtin can best be obtained by repeated preparative HPLC; indeed, crystalline azadirachtin was first obtained in this way. 396 A crude leaf extract has antifeedant properties, but the ... iron acton level crossing
