Abstract Two new compounds, 8(14),15‐isopimaradiene‐2α,3α,19‐triol (1), and 6α,7β‐dihydroxy‐17(20)‐ cis ‐5α‐pregna‐16‐one (2), together with four known compounds, a oxygenated rare phyllocladane, phyllocladan‐16a, 19‐diol (3), kaempferol‐3‐ O‐β‐D ‐galactopyranoside, kaempferol‐3‐ O‐α‐L ‐rhamnopyranoside and scopoletin, were isolated from the leaves of Ailanthus triphysa. Structures of 1–3 were elucidated on the basis of spectroscopic data as compared with related compounds.
