The effects of squamocin (1), bullatacin (2) and motrilin (3), 3 bis‐tetrahydrofuran Annonaceous acetogenins, isolated from Annona purpurea (Annonaceae), were investigated on several photosynthetic activities in spinach thylakoids. The results indicated that compounds 1–3 significantly inhibited bot...
