The effect of triterpene glycosides of cauloside C from Caulophyllum robustum M, stichoposide A from Stichopus japonicus S. and theasaponine from Thea sinensis Z. on permeability of plasmic membranes of Saccharomyces carlsbergensis for UV-absorbing substances was studied. It was found that incorporation of 14C-uridine from the endocellular pool into the yeast acid-insoluble fraction decreased under the effect of the triterpene glycosides as a result of the precursor leakage from the cell into the medium. It was found that the triterpene glycosides stimulated the leakage of the UV-absorbing substances with an absorption maximum at 260 nm from the cells. The maximum membranotropic effect was observed at 30--40 degrees C and in the presence of monovalent potassium, sodium, ammonium and lithium ions in the medium. Cauloside C and theasaponine, pentacyclic glycosides had the highest effect on the permeability at pH 4.8--5.6, while stichoposide A, a tetracyclic glycoside, had the highest effect at pH 7.0.
