[Non-taxoid chemical constituents from leaves of Taxus mairei].
OBJECTIVE
To study the non-taxoids in the leaves of Taxus mairei.


METHODS
The chemical constituents were isolated by chromatography and identified by spectral data.


RESULTS
Five compounds, taxamairin A (1), taxamairin B (2), sciadopitysin (3), ( - ) matairesinol (4), ponasterone A (5) were isolated and identified.


CONCLUSIONS
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.
