Limonoid
Chemical structure of the prototypical limonoid limonin
Limonoids are phytochemicals of the triterpenoid class which are abundant in sweet or sour-scented citrus fruit and other plants of the families Cucurbitaceae, Rutaceae, and Meliaceae.[1] Certain limonoids are antifeedants such as azadirachtin from the neem tree.[2]
Chemically, the limonoids consist of variations of the furanolactone core structure. The prototypical structure consists of four six-membered rings and a furan ring. Limonoids are classed as tetranortriterpenes.
Citrus fruits contain the limonoids limonin, and , while both neem seeds and leaves contain the limonoid azadirachtin, although higher concentrations are present in the former.
