Studies on the Carotenoid Pigments in the Abdominal Skin of Bombina Orientalis (). Occurrence of -Crotene and 4-Hydroxy-echinenone in the Abdominal Skin of Bombina Orienialis

[摘要] More than ten cartenoid pigments were separated from the dark red extracts of abdominal skin of Bombina Orientalis by TLC, and column chromatography, and the visible and infrared spectrum of purified carotenoids were determined. Two major pigments were identified as ¥â-carotene and 4-hydroxy-echinenone respectively through physical and chemical properties, chromatographic, visible and infrared spectral characteristics.
