A new phenylpropanoid glycoside compound isolated from Karelinia caspia

To study the constituents of Karelinia caspia (Pall.) Less, three phenylpropanoid derivatives and other compounds were isolated by silica gel, RP-18 chromatographic methods. Compound 1 was a new phenylpropanoid glycoside named as kareline A. Their structures were determined by spectroscopic analysis, including 1D- and 2D-NMR and mass spectrometry.
