Abstract:

In order to investigate the antifungal active components in root and stem of Schima superba, compounds were isolated and purified from the ethyl acetate extract using various column chromatography techniques, and their chemical structures were identified with NMR and MS spectroscopic methods. The activity of the isolated compounds against Candida albicans was evaluated in vitro by disk susceptibility assay and visual turbidimetry. Eight triterpenoid saponins were isolated from the EtOAc fraction of the alcoholic extract of S. superba, including berneuxia saponin A (1), sasanquasaponin III (2), maetenoside B (3), 3-O-{α-L-rhamno- pyranosyl-(1→2)-β-D-galactopyranosyl-(1→3)-[β-D-glucopyranosyl-(1→2)]-β-D-glucuronopyranosyl} primulagenin A (4), ternstroemiaside A (5), desacyl-boninsaponin A (6), sanchakasaponin F (7), yuchasaponin A (8). All compounds were isolated from S. superba for the first time. The results indicated that compounds 2, 3, 7 and 8 showed different degrees of anti-C. albicans activity in vitro. Among them, compound 7 showed notable activity against C. albicans. The minimum inhibitory concentrations against sensitive and drug-resistant strains of C. albicans were 0.016 mg/mL. The minimum fungicidal concentrations of sensitive and resistant strains were 0.132 and 0.016 mg/mL, respectively.
