Alkaline CuO degradation products of a marine sediment sample from off Sanriku (Pacific Ocean) were analyzed in detail by gas chromatography-mass spectrometry, with the following results: Approximately 150 compounds were identified in the degradation products. They include fatty acids (C_8〜C_<32>), alcohols (C_<16>〜C_<28>), α-hydroxy fatty acids (C_7〜C_<24>), β-hydroxy fatty acids (C_8〜C_22), ω-hydroxy fatty acids (C_<14>〜C_<24>), α, ω-dicarboxylic acids (C_4〜C_<22>), α-hydroxy α, ω-dicarboxylic acids (C_4〜C_<17>), lignin-derived phenolics (vanillyl phenols, syringyl phenols, p-coumaric acid and dimers of vanillyl phenols), and cutin-derived acids (9,16- or 10,16 -dihydroxy hexadecanoic acids, 8-hydroxy hexadecan-1,16- dioic acid, 9,10,18-trihydroxy octadecanoic acid, 9,10-dihydroxy octadecan-1,18-dioic acid, 6- or 7-hydroxy pentadecan-1,15-dioic acid), 11,18- dihydroxy octadecanoic acid and 11,18-dihydroxy octadecenoic acid (cis and trans). The applicability of these compounds as source indicators was discussed.
