Abstract: Four undescribed pyrethrins C-F (1-4) as well as four known pyrethrins (5-8) were isolated from seeds of Pyrethrum cinerariifolium Trev. The structures of compounds1-4 were elucidated by UV, HRESIMS, and NMR (1H and 13C NMR, 1H-1H COSY, HSQC, HMBC and ROESY), among which the stereostructure of compound4 was determined by calculated ECD. Furthermore, compounds1-4 were evaluated for their aphidicidal activities. The insecticidal assay results showed that1-4 exhibited moderate aphidicidal activities at the concentration of 0.1 mg/mL with the 24 h mortality rates ranging from 10.58 to 52.98%. Among them, pyrethrin D (2) showed the highest aphidicidal activity, with the 24 h mortality rate of 52.98%, which was slightly lower than the positive control (pyrethrin II, 83.52%).
