✦ Synopsis

Abstract

Two new ent‐kaurane diterpenes, wedelidins A (8) and B (9), together with eighteen other constituents, including the sesquiterpenoids 1 and 2, ent‐kaurane diterpenes 3–7, triterpenoids 10 and 11, steroids 12–14, and flavonoids 15–17 as well as benzene derivatives 18–20, were isolated from the aerial parts of Wedelia trilobata. The structures of wedelidins A (8) and B (9) were elucidated by extensive spectroscopic analyses (including UV, IR, NMR, and MS). Furthermore, the structures of compounds 2 and 3 were confirmed by X‐ray single‐crystal diffraction analyses.
