Description(4R)-4-(3-Furyl)-1,4,4a,5,6,6abeta,7,8,9,10,11,12-dodecahydro-10alpha-(angeloyloxy)-4abeta,7,9,9-tetramethyl-2,13-dioxo-7beta,11beta-methano-2H-cycloocta[f][2]benzopyran-8beta-acetic acid methyl ester belongs to the class of organic compounds known as limonoids. These are highly oxygenated, modified terpenoids with a prototypical structure either containing or derived from a precursor with a 4,4,8-trimethyl-17-furanylsteroid skeleton. All naturally occurring citrus limonoids contain a furan ring attached to the D-ring, at C-17, as well as oxygen containing functional groups at C-3, C-4, C-7, C-16 and C-17. ekeberin C2 is found in Cipadessa baccifera (Roth) Miq. , Ekebergia capensis, Khaya anthotheca, Khaya senegalensis L. , Swietenia mahagoni , Toona ciliata and Xylocarpus granatum . It was first documented in 2008 (Murata, T., et al.). Based on a literature review very few articles have been published on (4R)-4-(3-Furyl)-1,4,4a,5,6,6abeta,7,8,9,10,11,12-dodecahydro-10alpha-(angeloyloxy)-4abeta,7,9,9-tetramethyl-2,13-dioxo-7beta,11beta-methano-2H-cycloocta[f][2]benzopyran-8beta-acetic acid methyl ester.
