title: Terpenoids and their anti-feedant activity from Cipadessa cinerascens.
abstract: Eight tetranortriterpenoids (1-8) and two sesquiterpenoids (9 and 10) including two new compounds, cineracipadesin G (1) and 1β-hydroperoxy-6α-hydroxy-eudesm-4(15)-ene (9), were isolated from the EtOAc extract of branches of Cipadessa cinerascens. The structures of two new compounds were elucidated by 1D and 2D NMR and MS spectroscopic analyses. The anti-feedant activity of two tetranortriterpenoids (1 and 7) was tested and obvious anti-feedant effects were detected.
