An attempt was made to correlate insect antifeedant and growth regulatory activities of neem ( Azadirachta indica ) seed oil with the major tetranortriterpenoids. Selective elimination of triterpenoids by preparative high‐performance liquid chromatography, incorporation of the eliminated compounds in defined concentrations and bioassaying the resultant fractions against Spodoptera litura indicated the necessity to quantify major triterpenoids for correlation of bioactivity of neem oil.
