A new triterpene metabolite with an oleanane skeleton, has been isolated from Anagallis arvensis and its structure established on the basis of spectral analyses (including (1)H-(1)H and (1)H-(13)C COSY), performed both on the original compound and its acid-catalysed hydrolysis product.A single crystal X-ray diffraction analysis performed on the p-iodobenzoate derivative enabled the assignment of the absolute configuration. Key words: Anagallis arvensis; Primulaceae; scarlet pimpernel; oleanane triterpene; X-ray diffraction analysis.
