Abstract
Phytochemical investigation of the methanolic extract of Aegle marmelos (L.) Corr. (Rutaceae) roots resulted in the isolation of two new diterpenic coumarin ethers characterized as 8-(2´,6´,10´,14´-tetramethylhexadec-5´,13´-dien-3´-oxo) coumarin (2) and 8-(2´,6´,10´,14´-tetramethylhexadec-13´-en-3´-oxo) coumarin (3) and two new sesquiterpenic coumarin ethers identified as 8-(4´,10´-dimethyl-7´-isopropenyl-4´-hydroxy-6´-oxo-decalin) coumarin (4) and 8-(4´,10´- dimethyl-7´-isopropenyl-4´,5´-dihydroxy-6´-oxo-decalin) coumarin (5) along with known compound n-hexacosan-1-ol (1). The structures of the isolated compounds were established by spectral data analysis.
