Anti-inflammatory and Hepatoprotective Iridoid Glycosides from the Roots of .

Ten previously undescribed iridoid glycosides (-), including monoiridoids, hybrid iridoid-alkaloids, bis-iridoids, noriridoid-iridoid dimers, and tetramers, were isolated from the roots of Merr. Structural elucidation revealed unique sugar chains not previously observed for iridoids and complex tetrameric configurations that are rare in nature. Compounds , , and demonstrated significant anti-inflammatory effects, with IC values ranging from 6.

New Hydrogenated Phenanthrene Glycosides from the Edible Vegetable W.T.Wang with DPP-IV Inhibitory and Hepatoprotective Activity.

Based on molecular networking-guided isolation, 15 previously undescribed hydrogenated phenanthrene glycosides, including eight hexahydro-phenanthrenone glycosides, four tetrahydro-phenanthrenone glycosides, one dihydro-phenanthrenol glycoside, two dimers, and two known dihydrophenanthrene glycosides, were isolated from W.T.Wang, a popular regional edible vegetable at the northwest region of Vietnam.
