A dichloromethane-MeOH extract prepared from the aerial parts of Brickellia veronicaefolia inhibited the spontaneous contractions (IC50 = 39.22 microg/mL) of the guinea-pig ileum. Bioassay-guided fractionation of the extract led to the isolation of three new benzoic acid derivatives,
Three Uvaria species, namely U. klaineana, U. mocoli and U. versicolor were tested in vitro against Dermatophagoides pteronyssinus, the European house dust mite. The most active extracts were the Uvaria versicolor stems crude methanol and hexane extracts with EC(50) values of 0.095 g/m(2 )and 0.12
