(R)-(-)-(E)-2,6-DIMETHYL-3,7-OCTADIENE-2,6-DIOL 6-O-BETA-D-GLUCOPYRANOSIDE - NATURAL PRECURSOR OF HOTRIENOL FROM LULO FRUIT (SOLANUM-VESTISSIMUM D) PEELINGS

A glycosidic fraction was obtained from a methanolic extract of lulo fruit (Solanum vestissimum D.) peelings by Amberlite XAD-2 adsorption and methanol elution. Using preseparation by rotation locular countercurrent chromatography, subsequent acetylation, and liquid chromatographic purification, a glycoside was isolated in pure form whose structure was elucidated by DCI-MS and NMR analyses to be the 6-O-linked beta-D-glucopyranoside of (R)-(-)-(E)-2,6-dimethyl-3,7-octadiene-2,6-diol.
