1) We propose to name the glucoside, C_<26>H_<32>O_<11>.6H_2O (m.p. 171-171.5), and its aglucone, C_<20>H_<22>O_6.2H_2O (m.p. 142-141.5), symplocosin and symplocosigenol respectively from the name of its original plant.2) From symplocosigenol and its methyl derivatives such various compounds were prepared in each crystalline states as following alkyl, acyl, nitro, aud bromo-dertvatives;[table]3) We concluded that symplocosigenol has two methoxyl, two phenolic hydroxyl groups and none other active groups in its molecule. The fact that it gives brown resinous agulcone on the hydrolysis with mineralic acid, accordingly, may be properly elucidated on such assumption that the agulcone would have anoxygen-heterocyclic ring in the fundamental structure.
