摘要：

从水红木( Viburnum cylindricum ) 植物中分离出2 个新化合物, 1- phloroglucinyl- ( 6-methybutyryl )-B-D- glucopyranoside命名为cylindrin A ( 1) , 1- [ 4- ( 3- hydroxy-l propyl ) ]- pyrocatechol- ( 6-methybutyryl )-B-D- glucopyranoside, 命名为cylindrin B ( 2) , 以及7 个已知化合物tachioside ( 3) , syingic acid-4-B-D- glucopyran oside ( 4) , 1-B-D-glucopyranosyloxy-3-methoxy-5- hydroxybenzene ( 5 ) , 4- hydroxy- 3-methoxypheno-l 1-O-B-D- glucoside ( 6 ) , 4-hydroxy- 2, 6- dimethoxypheno-
l 1-O-B-D- glucoside ( 7) , phlorogluc ino-l 1-O-B-D-glucoside ( 8 ) , 1-B-D- glucosyloxy-2- ( 3-methoxy- 4- hydroxyphenyl) 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。

Abstract:

Viburnum cylindricum has been used in folk medicine in Yunnan. Two new phenolic glycosides, 1- phloroglucinyl-( 6-methybutyryl )-B-D- glucopyranoside named cylindrin A ( 1) , and 1- [ 4-3- hydroxy-l propyl ) ]-pyrocatechol- ( 6-methybutyryl )-
B-D-glucopyranoside named cylindrin B ( 2) , along with seven known phenolic glycosides tachioside ( 3) , syingic acid- 4-B-Dglucopyran oside ( 4) , 1-B-D-glucopyranosyloxy- 3-methoxy- 5- hydroxybenzene ( 5 ) , 4- hydroxy- 3-methoxypheno-l 1-O-B-D-glucoside ( 6) , 4- hydroxy- 2, 6- dimethoxypheno-l 1-O-B-D- glucoside ( 7) , phlorogluc ino-l 1-O-B-D- glucoside ( 8) , 1-B-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.
