A saponin (echinocystic acid-3-o- α -l – rhamnopyranosyl (1 à 5) – o – β - d – xylofuranosyl (1 à 5) – o – β - d – arabinofuranosyl (1 à 4) – o – β - d –glucopyranoside)have been isolated and identified from the leaves of clematis nepaulensis. Repeated chromatographic manipulations and spectral analysis (IR, 1H-NMR, and Mass) suggested the structure of saponin. Keywords: Saponin, Echinocystic acid, Isolation, spectral analysis
1H NMR spectral analysis and conformational behavior of n-alkanes in different chemical environments
