Phytochemical investigation of the fruit peels of Citrus reticulata Blanco.

Phytochemical investigation of the fruit peels of Citrus reticulata Blanco (Rutaceae) resulted in the isolation of three new phytoconstituents along with n-hexacosonoic acid. Their structures have been established as 18betaH-urs-5,11-dien-3beta-ol-11-one-3beta-D-glucopyranosyl-(4'-->1'')-D-glucopyranosyl-6''-(3''',4'''-dihydroxyl)-benzoate (reticulataursenoside), stigmast-5-en-3beta-ol-3beta-D-glucopyranosyl-4'-eicosanoate (citrusteryl arachidate), and lanost-5-en-3beta-ol-3beta-D-glucopyranosyl-4'-eicosanoate (citruslanosteroside) on the basis of spectral data analysis and chemical reactions.
