Chemical constituents with ɑ,β-unsaturated carbonyl group from the whole plants of Erigeron breviscapus (Vant.) Hand.-Mazz. (Asteraceae)

Phytochemical characterization of the whole plants of Erigeron breviscapus (Vant.) Hand.-Mazz. Led to the isolation of two indole derivatives (1–2), seven monoterpenoids (3–9), two sesquiterpenoids (10–11), and four pyrone derivatives (12–15). The structures of these compounds were examined with spectroscopic methods, and also by comparing with previously reported spectroscopic data. Among them, ten compounds (1–2, 6–11, 14–15) are reported from...
