从泰山盐肤木Rhustaishanensis的根茎中分得3个化合物，经与标准品对照，理化鉴别和波谱分析推定，化合物Ⅰ为没食子酸（gallicacid），Ⅱ为1－（2′，3′-二羟基苯基）－2-正庚基-1-壬烯-3-酮，是一新化合物，命名为盐肤木酮（rhusone），Ⅲ为moronicacid。
Three compounds were isolated from the rhizome of Rhustaishanensis. The compounds were determined to be gallic acid by physical and chemical identification and spectral analysis. The II was 1-(2′,3′-dihydroxyl). Phenyl)-2-n-heptyl-1-nonen-3-one is a new compound, named rhusone, and III is Moronic acid.
