Abstract

Five norisoprenoids were isolated from the green marine alga Ulva lactuca. Two new compounds were assigned to (3R,5R,6R,7E)3,5,6-trihydroxy-7-megastigmen-9-one (1) and (3S,5R,6S,7E)3,5,6-trihydroxy-7-megastigmen-9-one (2). The structures and absolute configurations of the five compounds were determined by analyses of NMR, MS and circular dichroism (CD).

摘要

从绿色海洋藻类石莼中分离出了五种降异戊二烯类化合物。两种新化合物被鉴定为(3R,5R,6R,7E)3,5,6-三羟基-7-巨藻素-9-酮(1)和(3S,5R,6S,7E)3,5,6-三羟基-7-巨藻素-9-酮(2)。通过核磁共振(NMR)、质谱(MS)和圆二色性(CD)分析确定了这五种化合物的结构和绝对构型。
