![furthermore contained a large amount of a sugar, which yielded d-phenylglucosazone and a quantity of potassium chloride. The portion of the alcoholic extract which was insoluble in water was a dark green resin. From this material the following com¬ pounds wrere isolated: (i) A new ester, cluytyl cluytinate, C49H9802 (m. p. 76'5°); (ii) triacontane, C'30H62; (iii) a new phytosterol, cluytiasterol, C^H^O, melting at 159°, and having [a]D — 52‘6°. Cluytiasteryl acetate melts at 139°. (iv) Cluytyl alcohol, C28H580, m. p. 82'5°; (v) palmitic, stearic, and cerotic acids, together with a small amount of a mixture of unsaturated acids; (vi) a new fatty acid, cluyiinic acid, C21H4202 (m. p. 69°); (vii) a new tetrahydric alcohol, cluytianol, C29H46*0(0H)4 (m. p. 300—305°). Cluytianol is isomeric with the trihydric alcohol, ipuranol, which it resembles in its general properties. Tetra-acetylcluytianol melts at 160°, and tetrabenzoyl cluytianol at 192°; (viii) a compound, C14H10O5, which is probably a trihydroxydihydroanthraquinone. The alcoholic extract of the root of Cluytia similis consisted chiefly of amorphous material, but it yielded palmitic and stearic acids; a higher fatty acid (m. p. 73°); a small amount of a mixture of unsaturated acids; and a quantity of cluytiasterol. It also contained some inorganic matter, in which the presence of copper, iron, manganese, aluminium, calcium, strontium, magnesium, sodium, and potassium was established.
