Abstract

Two triterpenyl fatty acid esters were isolated from the chloroform soluble fraction of Fagonia cretica and their structures elucidated as 3β-12-ursen-3yl-docosanoate (1) and 3β-12-ursen- 3yl-nonacosanoate (2) by 1D-NMR, 2D-NMR, mass spectrometric and chemical analyses. Both new compounds were also evaluated for their lipoxygenase inhibitory potential using Baicalein as a standard. [ABSTRACT FROM AUTHOR]

Abstract

In the present work two new compounds have been isolated from the whole plant of Pervoskia abrotanoides. The structures were elucidated by the extensive use of sophisticated spectroscopic techniques (¹HNMR, 13C-NMR, HMQC, HMBC, ¹H-¹H COSY, NOESY, EIMS, HREIMS, and IR). The structures were characterized as cholest-4,9(11)-diene-2α,3β-diol, 1 and 22α-hydroxy-12-oleanen-3-one, 2. Both the compounds 1 and 2 showed promising inhibitory activity against lipoxygenase enzyme. [ABSTRACT FROM AUTHOR]
