| Abstract: | The aerial parts of Ophryosporus chilca afforded several prenylated p-hydroxyacetophenones, two labdane derivatives and a cinnamyl ester. Ophryosporus peruvianus also contains prenylated p-hydroxyacetophenones. Three compounds were isolated for the first time; their structures were established by 1H NMR spectroscopy. |
