Identification and structure determination of four triterpene saponins from some Middle-East plants

Identification and structure determination of four triterpene saponins from some Middle-East plants

Four triterpene saponins were isolated from Arenaria filicaulis Boiss., Phytolacca dioica L. and Koelreuteria paniculata Laxm. Their structures and conformational behaviour were investigated by one‐ and two‐dimensional 1H and 13C NMR spectroscopy. Complete 1H and 13C assignments were achieved. Copyr...
