Abstract

Three kinds of type II cyanolipids were isolated as pure forms from Nephelium lappaceum using HPLC. The full structures were established by spectral and chemical investigations. (+)-Rangiformic acid from the lichen Cladonia rangiformis has been shown to be (+)-3S-methoxycarbonylheptadecane-1,2S-dicarboxylic acid by an NMR selective decoupling experiment with (-)-rangiformic anhydride.
