Monotropein, C16H22O11⋅CH3OH, was isolated from the domestic Monotropa Hypopithys L. (Japanese name “Shakujoso”) and it was proved to be identical with the corresponding glucoside isolated from the other plants belonging to the genuses of Pyrola and Chimaphila. In view of the fact that monotropein was also isolated from the other pyrolaceous saprophytes, Monotropa uniflora L. (Japanese name “Ginryoso-modoki”) and Monotropastrum globosum H. ANDR. (Japanese name “Ginryoso”), this glucoside is considered to be common to the pyrolaceous plants. In these three kinds of plants, a few sugars like glucose and sucrose, and some Gibbs' reaction-positive substances, assumed to be hydroquinone-type glucosides were detected by paper chromatography.
