Abstract: | The new caffeylated triterpene glycosides hederagenin 3-O-(6-O-caffeyl-β-D-glucopyranosyl)-(1→4)-O-β-D-xylopyranosyl-(1→3)-O-α-L-rhamnopyranosyl-(1→2)-O-β-L-arabinopyranoside and its 28-O-α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)-O-β-D-glucopyranosyl and 28-O-α-L-rhamnopyranosyl-(1→4)-O-6-O-acetyl-β-D-glucopyranosyl-(1→6)-O-β-D-glucopyranosyl esters were isolated from leaves of Kalopanax septemlobum var. maximowiczii introduced in Crimea. The structures of these compounds were established using chemical methods and NMR spectroscopy.__________Translated from Khimiya Prirodnykh Soedinenii, No. 3, pp. 263–267, May–June, 2005. |
