Objective: To study the chemical constituents from the barks of Lannea coromandelica. Methods: The chemical constituents were isolated and purified by column chromatography on silica gel column. NMR spectra were used for structural identification. Results: Thirteen compounds were isolated and identified as quercetin (1), (2. S,3. S,4. R,10. E)-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).
