The composition of the hydrocarbon extract of Betula pendula buds (Betulaceae) has been investigated. The following acids were identified in the extract: betulonic, moronic acid; 3,4-seco-olean-4(24)-en-19-on-3-oic; 28-acetooxy-3,4-seco-olean-4(24),13(18)-diene-3-oic; (20S)-hydroxy-3,4-seco- dammara-4(28),24-diene-3-oic, and (19R)-hydroxy-3,4-seco-taraxasta-4(24)-en-3- oic. Gas chromatography retention indices were determined for all the identified compounds. © 2012 Pleiades Publishing, Ltd.

This report is devoted to study of the hydrocarbon composition of the extract of buds of birch (family Betulaceae). We identified 3,5-dihydroxy-7, 4′-dimethoxyflavone, 5,7-dihydroxy-3,4′-dimethoxyflavone, 7-methoxy-4′,5-dihydroxyflavanone, 4′-methoxy-5,7-hydroxyflavanone, 5β,6α-dihydroxycaryophyllen-4(14),8(15)-diene ((1R,5R,6R,9S)-5,6- dihydroxy-11,11-dimethyl-4,8-methylenebicyclo[7.2.0]-undecane), 5β,6α-dihydroxycaryophyllen-3,8(15)-diene ((1R,5R,6R,9S)-5,6- dihydroxy-11,11-dimethyl-8-methylenebicyclo[7.2.0]undec-3-ene), 6α,9β-dihydroxy-α-humulene((1E,4E,6R,9S)-6,9-dihydroxy-4,11, 11-trimethyl-8-methylene-1,4-cycloundecanediene), 5β,6α,8β- trihydroxycariolan, and (1R,5R,6R,8R,9S)-trihydroxycariolan. The gas chromatographic retention indices of all identified compounds were determined. © 2012 Pleiades Publishing, Ltd.
