Certain other meliaceous seed extracts were equally active to azadirachtin in bioassays (Mikolajczak and Reed, 1987). TTiose of Aglaia cordata were more potent than extracts of neem toward larvae of Spodoptera frugiperda (Mikolajczak et al., 1989). A limonoid compound from Carapa procera had antifeedant activity comparable to that of azadirachtin, but much weaker insecticidal properties. This compound, methyl 3 3-isobutyryloxy-l-oxomeliac-8(30)-enate (42), also was found in Khaya senegalensis and K. nyasica (Mikolajczak et al., 1988). 

This group, to which limonin belongs, is characteristic of the Rutaceae and rare in Meliaceae. Obacunol (59) occurs in Lovoa trichiliodes (7) and in Carapa procera 183 dihydronomilin acetate (60) in Xylocarpus granatum 16, 142) and 6P-acetoxyobacunol acetate (61) in Trichilia trifolia. The stereochemistry of the 6-substituent in this compound is very unusual, but appears to be correct 201).
