Abstract:
:Cultured cells of Eucalyptus perriniana biotransformed (+)-menthol to its gentiobioside and triglucoside [2,6-di-O-(beta-D-glucopyranosyl)-beta-D-glucopyranoside]. The structures of these compounds were determined by means of NMR techniques.

PHYTOCHEMISTRY文献大全abstract::Lipid oxidation is a common metabolic reaction in all biological systems, appearing in developmentally regulated processes and as response to abiotic and biotic stresses. Products derived from lipid oxidation processes are collectively named oxylipins. Initial lipid oxidation may either occur by chemical reactions or ...
