Abstract

Six known phenolic glycosides. hyperin(2), androsin(3), homoarbutin(4), isohomoarbutin(4a), pirolatin(7) and monotropein(6), together with two new compounds, (1)[mp. 215 - 217$^{\circ}C$, C$\sub$23/H$\sub$32/O$\sub$11/] and (5)[mp. 121 -123$^{\circ}C$, C$\sub$18/H$\sub$26/O$\sub$8/] were isolated from the BuOH fraction of Pyrola japonica(Pyrolaceae). The structures of the known compounds were determined by chemical and spectroscopic methods. (omitted)
