【摘要】 从水红木(Viburnumcylindricum)植物中分离出2个新化合物,1-phloroglucinyl-(6-methybutyryl)-β-D-gluco-pyranoside命名为cylindrinA(1),1-[4-(3-hydroxyl-propyl)]-pyrocatechol-(6-methybutyryl)-β-D-glucopyranoside,命名为cylindrinB(2),以及7个已知化合物tachioside(3),syingicacid-4-β-D-glucopyranoside(4),1-β-D-glucopyr-anosyloxy-3-methoxy-5-hydroxybenzene(5),4-hydroxy-3-methoxyphenol-1-O-β-D-glucoside(6),4-hydroxy-2,6-dime-thoxyphenol-1-O-β-D-glucoside(7),phloroglucinol-1-O-β-D-glucoside(8),1-β-D-glucosyloxy-2-(3-methoxy-4-hydroxy-phenyl)propane-1,3-diol(9).它们的结构经波谱方法得到鉴定。3~9为首次从该种植物中分离得到。更多还原

【Abstract】 Viburnum cylindricum has been used in folk medicine in Yunnan.Two new phenolic glycosides,1-phloroglucinyl-(6-methybutyryl)-β-D-glucopyranoside named cylindrin A (1),and 1-[4-3-hydroxyl-propyl)]-pyrocatechol-(6-methybutyryl)-β-D-glucopyranoside named cylindrin B (2),along with seven known phenolic glycosides tachioside(3),syingic acid-4-β-D-glucopyran oside(4),1-β-D-glucopyranosyloxy-3-methoxy-5-hydroxybenzene(5),4-hydroxy-3-methoxyphenol-1-O-β-D-glucoside(6),4-hydroxy-2,6-dimethoxyphenol-1-O-β-D-glucoside(7),phlorogluc inol-1-O-β-D-glucoside(8),1-β-D-glucosyloxy-2-(3-methoxy-4-hydroxyphenyl) propane-1,3-diol(9) have been isolated from the EtOAc extracts of its aerial parts.Their structures were elucidated by means of spectroscopic method.Compounds 3-9 were isolated from this plant for the first time.更多还原
