Chemical Constituents from Barks of Lannea coromandelica

ObjectiveTo study the chemical constituents from the barks of Lannea coromandelica.MethodsThe chemical constituents were isolated and purified by column chromatography on silica gel column. NMR spectra were used for structural identification.ResultsThirteen compounds were isolated and identified as quercetin (1), (2S,3S,4R,10E)-2-[(2'R)-2′-hydroxytetracosanoyl amino]-10-octadecene-1,3,4-triol (2), aralia cerebroside (3), 5,5′-dibuthoxy-2,2′-bifuran (4), β-sitosteryl-3β-glucopyranoside-6′-O-palmitate (5), β-sitosterol palmitate (6), myricadiol (7), protocatechuic acid (8), p-hydroxybenzoic acidethyl ester (9), isovanillin (10), trans-cinnamic acid (11), palmitic acid (12), and stearic acid (13).ConclusionCompounds 2–13 are isolated from this plant for the first time.
