title: A new alkaloid from Dysoxylum binectariferum.
abstract: Two compounds (1 and 2) have been isolated from the stem bark of Dysoxylum binectariferum (Roxb.) Hook. f. ex Bedd. Compound 1 is rohitukine [5,7-dihydroxy-2-methyl-8-[4-(3-hydroxy-1- methyl)-piperidinyl]-4H-1-benzopyran-4-one], a known compound that has anti-inflammatory and immunomodulatory activities. Compound 2 is a new alkaloid, named rohitukine N-oxide, the structure of which was elucidated on the basis of spectral evidences and comparison with the 1H NMR data of rohitukine.
