From the twigs of Taxus mairei , 35 lignans, 2 sesquilignans, 4 flavonoids, 3 bisflavonoids, 13 phenolic derivatives, 2 sesquiterpenes, 3 bisnorsesquiterpenes, 3 long‐chain carboxylic acids and 4 steroids were isolated. The new lignans and phenolic glucosides include 7′‐hydroxynortrachelogenin, 7‐hydroxymatairesinol, 3′‐ O ‐demethylepipinoresinol, taxiresinol 9‐acetate, 3′‐ O ‐demethyltanegool, 8′‐epitanegool, 3,3′‐dimethoxy‐4,4′,9‐trihydroxy‐7,9′‐epoxylignan‐7′‐one, 3‐ O ‐demethyldihydrodehydrodiconiferyl alcohol, taxumaiglucoside A heptaacetate, taxumaiglucoside B heptaacetate, and taxumaiglucoside C heptaacetate. Their structures were determined by spectral methods.
