(Caryophyllaceae), wild growing in the Ukraine. In addition, five known triterpenoid saponins; i.e. herniariasaponins 1, 4, 5, 6, and 7 were also isolated. Their structures were elucidated by HRESIMS, 1D and 2D NMR spectroscopy, as well as by comparison with the literature data. Twelve herniariasaponins, the purified crude extract, and the saponin fraction were evaluated in vitro for their xanthine oxidase, collagenase, elastase, and tyrosinase inhibitory activity. Moreover, herniariasaponins 4, 5, and 7 were screened for their cholinesterase inhibitory potential. As a result, no or low inhibition towards the mentioned enzymes was observed. Image 1 • Twelve undescribed herniariasaponins were isolated from Herniaria glabra L. • Two undescribed pentacyclic triterpenoid aglycones were discovered. • Tested samples showed no or low enzyme inhibitory activities in vitro. • The target enzymes were xanthine oxidase, collagenase, elastase, tyrosinase, ChE.
