Abstract: Thirteen compounds were isolated from the fruits of Rubus chingii Hu.On the basis of spectroscopic data and physicochemical properties,their structures were elucidated as β-sitosterol(1),7α-hydroxy-β-sitosterol(2),daucosterol(3),ursolic acid(4),4-hydroxyphenylacetic acid(5),salicylic acid(6),adenosine(7),1-oxo-1,2-dihydroisoquinoline-4-carboxylic acid(8),aromadendrin(9),hyperoside(10),ligballinol(11), n-hexacosylferulate (12)and n-tetracosyl-p-coumarate(13).Compound 10 was isolated from the title plant for the first time,and compounds 2、5、7、9、12、13 were isolated from the genus Rubus for the first time.
