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 H-1-H-1 and H-1-C-13 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

Abstract
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 H-1-H-1 and H-1-C-13 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 configurationI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
