Carotenoids of short-neck clam, Veneus japonica, were studied on the muscles and viscera of three samples. Unsaponifiable matters of the crude oils of the samples were chromato-graphed on almina column and twelve fractions, A1-A12, were separated. Yields of the crude oils and carotenoids are shown in Table 1. As the absorption spectra of the unsaponifiable matters did not differ from those of the crude oils (Fig. 1), carotenoids of the samples seem to remain unaltered by saponification. Absorption spectra and absorption maxima of the separated carotenoids are shown in Figs. 2-5 and Table 2. Short-neck clam always contain β-carotene in relatively high amount but lack lutein, showing distinguishing traits from the other bivalves as will be reported in the following papers.
