Zusammenfassung:Methyl 5‐formyl‐1‐benzofuran‐6‐carboxylate (1) and the two clerodane diterpenes, methyl 6‐oxocleroda‐3,13‐dien‐15,16‐olid‐18‐oate (2) and 2β‐(2‐methylbutanoyl)cleroda‐3,13‐dien‐15,16‐olid‐18‐oic acid (3), together with 15 known compounds, were isolated from the aerial parts of Pulicaria wightiana. The structures of the new compounds 1, 2, and 3 were established by spectroscopic (mainly 1D‐ and 2D‐NMR) methods.
