Phytochemical investigations of the ethanolic extract of leaves of clutia lanceolata(Family:Euphorbiaceae)resulted in the isolation of four compounds viz.3,4-dihydroxy-2-methylbenzoic acid(1),2,20-dihydroxy-1,10-binaphthyl(2),1,3,8-trihydroxy-6-methylanthracene-9,10-dione(3)and 5-hydroxy-1,7-bis(4-hydroxy-3-methoxyphenyl)hepta-1,4,6-trien-3-one(4).Although all the isolated compounds were known but this was the first report from this plant *** structures were established on the basis of chemical and physical evidences *** analysis,FT-IR,1 H-NMR,13CNMR and mass spectral *** of compound 2 and 4 was further authenticated by single-crystal X-ray analysis and density functional theory *** isolated compounds(1–4)were screened for AChE enzyme inhibition assay in which compound 3 and 4 were found to be more potent AChE *** docking study of potent AChE inhibitor was performed to find the probable binding mode of the compounds into the active site of ***,the isolated compounds were also screened for in vivo cytotoxicity by brine shrimp lethality assay.
