| Abstract: | Four coumaronochromones, formosanatins A–D (Fig. 1 and Fig. 2–4), and a flavanone, euchrenone a16 (Fig. 1 and Fig. 2), along with four known compounds, euchretins E and G, euchrestaflavanone A, and daidzein, were isolated from the roots of Euchresta formosana. The structures of Fig. 1 and Fig. 2– Fig. 1 and Fig. 2 were established by spectroscopic analyses. |
