From Ligustrum oualifolium Hassk. leaves 2-( 4'-hydroxyphenyl) ethanol was isolated.The privet (Ligustrum, Oleaceae) has repeatedly been the subject of chemical examinations. Isolated from leaves and/or bark of various L i p s f r u m species have been: rnannitol I), the glycoside syringoside (syringin, ligustrin) 2 ) , the triterpene canboxylic acids oleanolic acid 3 ) and ursolic acid 4 ) , cerylpalmitate, behenic acid, a phytosterol, possibly identical with sitosterol5), 4-hydroxycinnamic acid G ) , a compound C22H34037), a compound C,,W3,038) a waxy substance G4H48(50)028), and two carboxylic acids C14H2dO4 8 ) and C15H3004 6 ) .W e succeeded in isolating 2~( 4'-hydroxyphenyl) ethanol (tyrosol) from an alcohollic extract of Ligusfrum oualifolium Hassk. 9 ) leaves, after hydrolysis by means of the cation-exchange resin Dowex-50 in the acid 1) G.
