Triumfetta pseudocana is a medicinal plant with cool properties. It is used in folk medicine to treat a number of diseases. Currently, there are not many published studies on the biological activity and especially the chemical composition of this plant. In this study, we chose to study the chemical composition from leaves and stems of Triumfetta pseudocana collected in Dalat, Lamdong province, Vietnam in July 2017. By chromatography, four compounds were isolated, include: tiliroside (1), friedelan-3-one (2), 3β-hydroxyfriedelane (3) and triumboidin (4). Their structures were determined by spectroscopic methods (1D and 2D-NMR) and in comparison with the reported data. This is the first time the chemical composition of the species Triumfetta pseudocana has been investigated.
