Three new dihydrophenanthrofurans, pleionesins A–C (1–3), together with two known dihydrophenanthrenes (4–5) were isolated from the tubers of Pleione yunnanensis (Rolfe). The complete 1 H and 13 C NMR spectra assignments of these compounds were carried out using 1D and 2D NMR experiments ( 1 H, 13 C, selective 1D NOE, HSQC and HMBC).
