The glycosides in mono-, di- and trihydroxylated terpene and norisoprenoid alcohols and also those in the related shikimate pathway have been isolated on C18 reversed-phase cartridges and then fractionated into classes of different polarity at increasing percentages of methanol. The benzyl alcohol glycosides are the most polar, while those of terpene monohydroxylated alcohols and geranic acid are the least polar. The terpene diols, linalool furanoid and pyranoid oxides and also norisoprenoid precursors show intermediate polarity and separate into well defined fractions according to their polarity.
