(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
H. Wintoch et al., (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, Journal of agricultural and food chemistry, 41(8), 1993, pp. 1311-1314
A glycosidic fraction was obtained from a methanolic extract of lulo f
ruit (Solanum vestissimum D.) peelings by Amberlite XAD-2 adsorption a
nd methanol elution. Using preseparation by rotation locular countercu
rrent chromatography, subsequent acetylation, and liquid chromatograph
ic 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.
