Two triterpenoid saponins were isolated from an aqueous or a methanolic extract of camellia (Camellia japonica) leaf. They had an antifungal activity characterized by abnormal germination of conidia. These saponins were composed of 3β-hydroxy-18β-acetoxy-28-norolean-12-en-16-one or 3β,8β-dihydroxy-28-norolean-12-en-16-one as aglycon, and D-glucuronic acid, D-glucose and two moles of D-galactose as the sugar moiety. The authors have named these new saponins "Camellidin, " which might have value for studies in the fields of phytopathology and biochemistry.
