Abstract: The systematic investigation on the roots of Taxus wallichiana has resulted in the isolation of nine taxoids-taxol 1 baccatin III 2, baccatin IV 3, taxusin 4, a C-14 oxygenated taxoid 5, 1β-hydroxybaccatin I 6, pentaacetoxy taxadiene 7, a dibenzoylated rearranged taxoid 8, 7-xylosyl-10-deacetyl-taxol C 9 and three phenolic compounds (-) seco-isolariciresinol 11, taxiresinol 12 and isotaxiresinol 13. The compounds have been characterized on the basis of their spectral characteristics. The occurrence of taxoid 9 in the roots of the plant is quite significant. The distribution of the above compounds in other parts of the plant are also summarized.
