Seven anthraquinones were isolated from the ethyl alcohol extracts of the roots of Rubia Cordifolia L. By means of spectrometric data combined with physico-chemical properties, six of them were identified as 2-methyl-1,3,6-trihydroxy-9,10-anthraquinone (I), 1-hydroxy-9,10-anthraquinone(II), 1,2,4-trihydroxy-9,10-anthrequinone(III), 2-methyl-1,3,6-trihydroxy-9,10-anthraquinone-3-O-beta-D-glucoside(IV), 1,2-dijhydroxy-9,10-anthraquinone-2-O-beta-D-xylosyl(1-->6)-beta-D -glucoside(V) and 1,3-dihydroxy-2-hydroxymethyl1-9,10-anthraquinone-3-O-beta-D- xylosyl(1-->6)-beta-D-glucoside(VI). VII is a new compound. Its structure was elucidated to be 2-methyl-1,3,6-trihydroxy-9,10-anthraquinone-3-O-beta-D-xylosyl(1-->2)-b eta-D- (6'-O-acetyl)glucoside.
从茜草根部的乙醇提取物中分离出七种蒽醌。借助光谱数据并结合物理化学性质，其中六种被鉴定为2-甲基-1,3,6-三羟基-9,10-蒽醌（I）、1-羟基-9,10-蒽醌（II）、1,2,4-三羟基-9,10-蒽醌（III）、2-甲基-1,3,6-三羟基-9,10-蒽醌-3-O-β-D-葡萄糖苷（IV）、1,2-二羟基-9,10-蒽醌-2-O-β-D-木糖基（1→6）-β-D-葡萄糖苷（V）和1,3-二羟基-2-羟甲基-9,10-蒽醌-3-O-β-D-木糖基（1→6）-β-D-葡萄糖苷（VI）。VII是一种新化合物。其结构经鉴定为2-甲基-1,3,6-三羟基-9,10-蒽醌-3-O-β-D-木糖基（1→2）-β-D-（6'-O-乙酰基）葡萄糖苷。
