Abstract A new lignanoid (1), together with six known lignanoids (2–7) and four known flavonoids (8–11), were isolated from the EtOAc extract of Liparis japonica. Their structures were determined by analyzing the HRESIMS, NMR, CD spectroscopic data, and comparing with the reported literatures. Among them, 1 was a new compound, 2–11 were first isolated from L. japonica and the genus of Liparis. The chemotaxonomic significance of these isolates was comprehensively discussed.
