Chemical constituents with ɑ,β-unsaturated carbonyl group from the whole plants of Erigeron breviscapus (Vant.) Hand.-Mazz. (Asteraceae)
2020
Abstract 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 Erigeron breviscapus for the first time. In addition, three compounds (2, 8–9) are isolated for the first time from Asteraceae family. On the basis of chemical research, we also described the chemotaxonomic significance of these compounds.
