Complete assignments of (1)H and (13)C NMR data of three new dihydrophenanthrofurans from Pleione yunnanensis.
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).
