The phospholipid fatty acid composition of the sponge Amphimedon complanata was reinvestigated, and the 2-methoxy-13-methyltetradecanoic acid, 2-methoxy-14-methylpentadecanoic acid, and 2-methoxy-13-methylpentadecanoic acid were identified for the first time in nature. Structure characterization was accomplished by means of gas chromatographic retention times and gas chromatography-mass spectrometry. These acids could have originated from bacteria in symbiosis with the sponge.
对扁平阿氏海绵的磷脂脂肪酸组成进行了重新研究，首次在自然界中鉴定出2-甲氧基-13-甲基十四烷酸、2-甲氧基-14-甲基十五烷酸和2-甲氧基-13-甲基十五烷酸。通过气相色谱保留时间和气相色谱-质谱联用进行结构表征。这些酸可能源自与海绵共生的细菌。
