从西南远志的乙醇提取液中分离得到5个酮类化合物,利用理化常数和波谱解析的方法鉴定结构,分别确定为:1,5-二甲氧基-2,6-二羟基酮;1,2,8-三甲氧基-3,6-二羟基酮;1,3,8-三羟基-2,6-二甲氧基酮;1,2,3-三甲氧基-6,8-二羟基酮和1,3,6,8-四羟基-2,7-二甲氧基酮。
Five ketones were isolated from the ethanol extract of Polygala tenuifolia and their structures were identified by physicochemical constants and spectral analysis, which were identified as: 1, 5-dimethoxy-2,6-dihydroxychromanone; 1,2,8-trimethoxy-3,6-dihydroxybenzaldehyde, 1,3,8-trihydroxy-2,6-dimethoxychioride, 1,2,3-trimethoxy-6 , 8-dihydroxychlorandone and 1,3,6,8-tetrahydroxy-2,7-dimethoxycoumarone.
