Abstract

New Sester- and triterpenic coumarin ethers from the roots of Aeglemarmelos (L.) Corr.

Author(s): M. Zaffer Ahmad, Mohammed Ali and Showkat. R. Mir

Phytochemical investigation of the methanolic extract of Aeglemarmelos (L.) Corr. (Rutaceae) roots resulted in the isolation of two new sesterterpenic coumarin ethers characterized as 8-(2´,6´,10´,14´,18´-pentamethyl-n-eicos-1´- 5´,13´,17´-teraene-10´-oxy) coumarin (2) and 8-(2´,6´,10´,14´,18´-pentamethyl-nonadec-8´-12´,18´-triene-2´-ol-3- oxy) coumarin (3) and two new triterpenic coumarin ethers identified as 8–(2´ ,6´,10´,14´,18´, 22- hexamethyltetracos-1´,13´,17´, 21´-tetraene-10´-oxy)coumarin (4) and 8–(2´,6´,10´,14´,18´, 22´-hexamethyl-22- methoxymethylene-tetracos-1´,3´,5´,7´,11´-pentaene-9´β-ol-13´β-methoxy -14´-oxy) coumarin (5) along with nhexacosan- 1-ol (1). The structures of the isolated compounds were established by spectral data analysis.
