As well as three known resorcylic acid lactones, 'monocillin IV' (1), 'monocillin II' (5) and radicicol (6) which were also isolated and identified, where compounds 4–6 show good binding affinity for the human opioid receptors.

These findings have important implications for the potential psychoactive effects with this class of compounds.
