The petroleum ether insoluble substances in wax from green coffee beans were fractionated without preceding derivatization by polyamide column chromatography. The main fraction of these substances was found to consist of N subindice {DF}-alkanoyl-5-hydroxytryptamine (C-5-HT). C-5=HT was fractionated by high-pressure liquid chromatography (h.p.l.c.) on a LiChrosorb 10 RP18 column; the amount of the main peak (N subindice {DF}-behenoyl-5-hydroxytryptamine: C subindice 22-5-HT) as determined by h.p.l.c. can be used as an analytical parameter for the amount of wax present in green coffee beans
