Saponins 12-20 complement C3 Homo sapiens 133-136 8555271-7 1996 The saponins glycosylated only at C-3 could also exhibit the same activity with somewhat different action profiles when the glucuronic acid is esterified, while those with the free glucuronic acid required cholesterol in the liposomes to induce permeability change thereof. Saponins 4-12 complement C3 Homo sapiens 34-37
