牛蒡根化学成分研究

Chemical Constituents of the Root of Arctium lappa L.

从牛蒡根95%乙醇提取液中分离得到6个化合物,通过理化性质和波谱学方法鉴定出5个化合物分别为牛蒡子苷(1)、山柰酚(2)、腺苷(3)、羟基茄碱(4)、spirosl-3-O-α-L-rhamnopyrannosyl-(1→4)-O-β-D-galactopyr-anosyl(5),其中化合物2～5为首次从该种植物中分离得到。

Six compounds were isolated trod purified from 95 % ethanol extract of the root of Arctium lappa L. by chromatographic methods. Among them, five chemical constituents were identified by physico-chemical and spectroscopic analysis as aretiin（ 1 ）, kaempferol （ 2 ）, adenosine （ 3 ）, solasonine （ 4 ）, and spirosl-3 -O-α-L-rhamnopyrannosyl- （ 1 -4 ） -O-β- D-galactopyranosyl（5）. Compounds 2 - 5 were firstly isolated from the burdock root.
