    SOME OBSERVATIONS REGARDING “OLEUROPEIN ” FROM OLIVE LEAVES.* BY FREDERICK B. POWER FRANK TUTIN. Quite recently Bourcjuelot and \ intilesco have brought to notice a product obtained by them from the leaves and fruit of the olive tree, the preparation and characters of which they have described in a communication bearing the follow¬ ing title. Sur l oleurojpeine, nouveciu principe de nature glucosidique retire d'olivier (Olea europaea, L.). Compt. rend.de VAcad, des Sciences, 1908, 147, pp. 553 535; J- Pkarm. Cliim., 1908, 28, pp. 303-314; also this Journal, Nov. 7, 1908, p. 588. In the beginning of their communication the above- mentioned authors state that they have specially considered a paper published some years ago by G. Korner (Gazz. chim. ital, xviii., 1888, p. 209), in its relation to the investigation of a crystalline substance designated olivil, this substance having first been isolated in 1816 by Pelletier from a gum-resin that exudes spontaneously from the bark of the olive tree. They remark further that, although Korner had shown olivil not to be a glucoside, he suggested that it might be a decomposition product of a glucoside occurring in the plant, but was not successful in isolating such a substance. In this connection it may, however, be noted that olivil, C20H24O7, has more recently been examined by Korner and Vanzetti (AttiR. Accad. Lincei, 1903 [v.] ,12, 1, 122), and that the occurrence of the latter compound * Communicated from the Wellcome Chemical Research Laboratories
