Three new alkaloids and three new phenolic glycosides from Liparis odorata.

Abstract 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.
