OBJECTIVE To study the identification of Sargassum fusiforme and other sargassos (algae from the genus Sargassum) by targeted lipidomics combined with chemotaxonomy methods. METHODS Twenty-seven batches of S. fusiforme were collected and the GC-MS fingerprint of fatty acids (FAs) was established. The principal component analysis and orthogonal partial least squares discriminant analysis were used to compare S. fusiforme with other 8 species, total 22 batches of sargassos. Based on the differential FAs between S. fusiforme and other sargassos, combined with the analysis of FA biosynthesis pathway, the Q-marker was screened. RESULTS A total of 29 common FAs were identified by the fingerprint, and the similarity was greater than 0.96. The chemical pattern recognition method can well distinguish S. fusiforme from other 8 species, and the discrimination model established by this method can accurately verify 15 batches of commercial slices. Based on the analysis of differential FAs and FA biosynthesis pathway, monounsaturated fatty acid was found to play an important role in chemical classification. The ratio C20∶1 n-9/C16∶1 n-7 was proposed to be used as a candidate Q-marker for the identification of S. fusiforme and 14 batches of commercial slices can be accurately verified. CONCLUSION This study establishes the identification model of S. fusiforme and other confused sargassos, finds the Q-marker of FAs, and provides a reference for the establishment of the identification method of TCM SARGASSUM.
