Cycloartanes and pentacyclic triterpenes from Awka and ijebuode propolis and evaluation of their antimicrobial activity

Abstract

<jats:p>Chemical investigation of propolis samples from southern Nigeria led to the isolation of cycloartanetype triterpenes namely: 24-methylene cycloartanol and ambonic acid along with pentacyclic triterpenes: Lupeol and α, β-amyrins. All compounds were identified and structures elucidated using proton nuclear magnetic resonance (1HNMR) spectroscopic data and comparison with literature.</jats:p>
