An investigation of three species of Rapanea, R. umbellata, R. lancifolia and R. guyanensis, has led to the identification of three terpeno-p-hydroxybenzoic acids, 3-geranyl-4-hydroxy-5-(3'',3''-dimethylallyl)-benzoic acid; 5-carboxy-7-(3'',3''-dimethylallyl)-2-(1'-hydroxy-1',5'-dimethylhex-4'-enyl)-2,3-dihydrobenzofuran and 6-carboxy-8-(3'',3''-dimethylallyl)-3α-hydroxy-2α-methyl-2-(4'-methylpent-3'-enyl)-3,4-dihydrobenzopyran and two triterpenoids which appear to be novel. The two new compounds were identified on the basis of spectroscopic analysis as 24(E)-3-oxo-dammara-20,24-dien-26-al and 24(E)-3α-hydroxycycloart-24-en-26-al.
