The features of the ~SC NMR spectrum that we obtained of the glycoside isolated and literature figures for spiraeoside from plants of the genus Allium  are very close. The values of the signals of the carbon atoms of quercetin 3'-glucoside -C-2 146.3, C-3 136.2, C--I' 122.1, C-2' 116.7, C-3' 145.0, C-4' 149.1, C-5' 116.1, C-6' 123.3 -calculated in the… (More)
The fatty acid compositions of the oils (Table 2) were studied by gas-liquid chromatography on a Vyrukhrom instrument with a flame-ionization detector. The fatty acids were analyzed in the form of their methyl esters  on an 0.4 × 250 cm steel column filledwithChromaton NAW (0.40-0.60 mm) impregnated with 15% of poly(ethylene glycol succinate). Column… (More)
The synthesis has been achieved of water-soluble 6-O-monoesters of sucrose with natural coumarins — karatavikic and galvanic acids — by the transesterifacation of their methyl esters with sucrose. The structures of the compounds obtained have been confirmed by IR, UV, PMR, and13C NMR spectroscopies.
The synthesis has been performed of α-monoglyceride derivatives of coumarins — karatavic and galbanic acids and their modified derivatives — phosphates. The structures of the compounds have been confirmed by IR, UV, PMR, and13C and31P NMR spectroscopies.
