【 摘 要 】
The chemical composition of the ethanolic extract of the leaves and roots from Philodendron imbe Schott was investigated. The main constituents isolated the leaves were b-sitosterol one polyprenoid hexaprenol, and 6b-hydroxy-stigmast-4-en-3-one, a steroid, not yet reported in the Philodendron gender. A mixture of constituents, namely, ethyl myristoleate, a-bisabolol, ethyl isopalmitate, 3-octadecenyl-phenol and the major component ethyl palmitate, were isolated from the roots. Structure elucidation of these secondary metabolites was accomplished by spectrometric analysis, including 1D and 2D NMR experiments such as 1H, 1H and 1H,13C-COSY.
