Components of the ovaries of Japanese toad (Bufo vulgaris), 2-3 days after being caught, were examined by paper chromatography by the Zaffaroni system and gamabufotalin, γ-sitosterol, and palmitic acid were isolated. Paper chromatography with the Zaffaroni system indicated the presence of desacetylcinobufagin, desacetylcinobufotalin, cinobufotalin, telocinobufagin, and hellebrigenin. Water-soluble components appeared as three spots on paper chromatogram but they could not be isolated and identified.
