From the stem of Laseguea erecta the triterpene lupeol, the cumarine scopoletin, the lignoid pinoresinol and digitoxigenin alpha-L-tevetoside, known as thevetioside, were isolated. The structures were identified by IR, mass, ¹H and 13C NMR spectroscopy, including 1D and 2D techniques, together with comparison with literature data.
