Three new alkaloids and three new phenolic glycosides from Liparis odorata

Three new alkaloids, liparis alkaloid A (1), B (2), C (3), and three new phenolic glycosides, liparis glycoside H (4), I (5), J (6), together with three known phenolic glycosides (7–9) were isolated from the whole plant of Liparis odorata. Their structures were characterized on the basis of extensive 1D-, 2D-NMR and HR-ESI-MS experiments. In addition, compounds 1–3 revealed hypolipidemic effects in the in vitro bioassays, and the ability to inhibit LPS-induced NO production of these isolated phenolic glycosides (4–9) was also evaluated.
