Three new saponins, named kudinosides A, B and C, were isolated from the leaves of Ilex kudincha. On the basis of spectroscopic analysis and chemical transformation their structures were elucidated as 3-O-β-d-glucopyranosyl - (1 → 3) - [α - l - rhamnopyranosyl - (1 → 2)] - α - l - arabinopyranosyl - β - kudinlactone, 3 - O - β - d - glucopyranosyl - (1 → 2) - β - d - glucopyranosyl - (1 → 3) - α -l - arabinopyranosyl - β - kudinlactone and 3 - O - β - d - glucopyranosyl - (1 → 2) - β - d - glucopyranosyl - (1 → 3) - [α -l - rhamnopyranosyl - (1 → 2)] - α - l-arabinopyranosyl-β-kudinlactone.
