Structural Elucidation and Computational Study of Limonoids fromChisocheton Erythrocarpus (Meliaceae)

Limonoid is a type of modified triterpenes that are abundant in the family Meliaceae. Their production is confined to several closely related families in the order Rutales such as Rutaceae, Simaroubaceae, Cneoraceae, and Meliaceae. Among them, Meliaceae family produces the most variety of limonoid skeletons. Biosynthetically, limonoids are derived from triterpenes by having lost four carbon atoms in the final product. Hence they are formally...
