Rangiformic acid is the monomethylester of (12). Caperatic acid (13) is derived from rangiformic acid by hydroxylation. [Pg.499]

The higher fatty acids and their lactones occurring in lichens can be divided into three groups ) -lactone acid derivatives [nine members, e.g., protolichesterinic acid (1)] dibasic fatty acids [roccellic acid (2)] and tri-basic fatty acids [caperatic, nor- and rangiformic acids (3)]. In addition, two tetrahydroxy fatty acids, e.g., ventosic acid [CH3(CH2)8(CHOH)2-CH2— (CH0H)2(CH2)7C00H] have been reported (Solberg, 1957). All aliphatic lichen acids are optically active. [Pg.525]
