What is Antifeeding activity of limonoids from Khaya senegalensis (Meliaceae) about?
**Abstract:** Fifteen B,D‐secolimonoids of mexicanolide, rearranged phragmalin, methyl angolensate and glycoside types have been isolated from ether and acetone extracts of the stem bark of __Khaya senegalensis__ (Desr.). The antifeedant activity of the isolated compounds was assessed by conventional choice leaf disc method on the third‐instar larvae of __Spodoptera littoralis__ (Boisd.). Khayalactol, 1‐__O__‐acetylkhayanolide A, 2‐hydroxyseneganolide, khayanolide A, khayanolide D and methyl angolensate displayed strong antifeedant activity at 1000 __μ__g/ml with antifeedant percentages of 83.8, 61.9, 60.1, 59.5, 57.1 and 55.7, respectively. 2‐Hydroxyseneganolide and khayanolide D showed high activity at 500, 300 and 200 __μ__g/ml while 1‐__O__‐acetylkhayanolide A was the only compound that revealed antifeedant activity at a concentration as low as 100 __μ__g/ml. Antifeedant activity was dose‐dependent in some of the isolated compounds. Correlation between antifeedant activity of the isolated compounds and chemical structure was discussed.
