Phytochemical investigation on the whole plant of Eryngium yuccifolium resulted in the isolation and identification of three phenolic compounds (1-3)and 12 polyhydroxylated triterpenoid saponins, named eryngiosides A-L (4-15), together with four known compounds aempferol-3-O-(2,6-di-O-trans-p-coumaroyl)- b-D-glucopyranoside (16), caffeic acid (17), 21b-angeloyloxy-3b-[b-D-glucopyranosyl-(1?2)]-[b-D-xylopyranosyl-(1?3)]-b-D-glucuronopyranosyloxyolean-12-ene-15a,16a,22a,28-tetrol (18), and saniculasaponin III (19). This study reports the isolation of these compounds and their structural elucidation by extensive spectroscopic analyses and chemical degradation ERYNGIUM YUCCIFOLIUM APIACEAE TRITERPENOID SAPONINS PHENOLIC COMPOUNDS ERYNGIOSIDES A-L CAMELLIAGENIN A A1-BARRIGENOL R1-BARRIGENOL https://drive.google.com/file/d/1CKwdKjXs7pg4Wm9ZAov0xuunIH1w5GSg/view?usp=drivesdk https://drive.google.com/file/d/1CKwdKjXs7pg4Wm9ZAov0xuunIH1w5GSg/view?usp=drivesdk 250602 20260521091154.0
