Abstract
The chemical investigation on the leaves of T.wallichiana from Kashmir resu lt in the isolation of 19-acetoxylated taxoid 1, a brevifoliol derivative 3 and ponasterone 4. These compounds have been characterized on the basis of their one dimensional and two dimensional NMR data and FAB-MS analysis.
