Three New Phenolic Glycosides from the Fertile Sprouts of Equisetum arvense

CHANG Jun, XUAN Li-Jiang, XU Ya-Ming   

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.

摘要:从问荆 (Equisetumarvense L .)营养茎的水溶性成分中分离到 12个化合物。经波谱解析和化学方法鉴定 ,其中 3个新的酚甙化合物分别命名为equisetumosideA (3-methoxy-11,12-dihydroxy_phenylhexane-9-one-4-O-β-D-glucopyra noside)、equisetumosideB (3-methoxy-4,11-dihydroxy-phenylhexane-9-one-12-O-β-D-glucopyranoside)和equisetumosideC (cis_ferulicacidpotassiumsalt 4-O-β-D-glucopyranoside) ;其他成分鉴定为尿甙、次黄甙、2′-脱氧次黄甙、2′-脱氧胞甙、色氨酸、胸甙、5-羧基-2′-脱氧尿甙、松柏甙和莰非醇-3-O-β-D-槐糖基-7-O-β-D-吡喃葡萄糖甙。这些化合物均为首次从该植物中分离得到。
