Abstract:

Three new phenolic glycosides, named as equisetumoside A (3-methoxy-11,12-dihydroxy-phenylhexane-9-one-4-O-β-D-glucopyranoside), equisetumoside B (3-methoxy-4,11-dihydroxy-phenylhexane-9-one-12-O-β-D-glucopyranoside) and equisetumoside C ( cis -ferulic acid potassium salt 4-O-β-D-glucopyranoside) were isolated from the water-soluble extract of fertile sprouts of Equisetum arvense L. (Equisetaceae), together with uridine, inosine, 2′-deoxyinosine, 2′-deoxycytidine, tryptophan, thymidine, 5-carboxy-2′-deoxyuridine, coniferin, and kaempferol 3-O-β-D-sophoroside-7-O-β-D-glucopyranoside. Their structures were elucidated by spectroscopic analysis and chemical transformation.
