Interpretive Summary: A method is described for the isolation of two key metabolites in the limonoid biosynthetic pathway critical to citrus quality. The compounds were isolated from young Chandler pummelo seedlings and characterized. Their isolation will facilitate the development of methods to improve citrus quality and identify new Citrus cultivars that will enhance human nutrition.

Technical Abstract: A method combining solid-phase extraction and reverse-phase high-performance liquid chromatography is described for the isolation of two key metabolites in the limonoid biosynthetic pathway critical to citrus quality. Potassium salts of limonoate A-ring lactone and nomilinoate A-ring lactone were isolated from young Chandler pummelo seedlings and characterized on the basis of proton and carbon NMR data.
