OBJECTIVE: To study the non-taxoids in the leaves of Taxus mairei. METHOD: The chemical constituents were isolated by chromatography and identified by spectral data. RESULT: Five compounds, taxamairin A (1), taxamairin B (2), sciadopitysin (3), ( - ) matairesinol (4), ponasterone A (5) were isolated and identified. CONCLUSION: Compounds 3-5 were isolated from this plant for the first time, compounds 1 and 2 were isolated from the leaves of T. mairei for the first time.
