刺楸(Kalopanax septemlobus)根在中国传统医学中是一种常用中药,用于抗风湿,抗炎症,祛痰和镇静。作为对五加科(Araliacea)植物化学成分研究的一部分,作者对从中国东北地区吉林省采集的刺楸根的三萜皂甙进行了研究。本文报道4种新皂甙和三种已知皂甙的分离和结构鉴定。将刺楸根的甲醇提取物悬浮在水中,用乙酸乙酯提取后,再用水饱和的正丁醇萃取。正丁酵提取物进行硅胶层析,最后经重晶或高压液相层析精制,得到7种皂甙:1～7,收
Kalopanax septemlobus root is a commonly used traditional Chinese medicine in traditional Chinese medicine for anti-rheumatic, anti-inflammatory, delirium and sedation. As part of the study of the chemical constituents of Araliacea, the authors studied triterpenoid saponins from the Robinia pseudoacacia root collected from Jilin Province in Northeast China. This paper reports the isolation and structure identification of four new saponins and three known saponins. The methanol extract of Robinia pseudoacacia root was suspended in water, extracted with ethyl acetate, and extracted with water-saturated n-butanol. The crude butyl yeast extract was chromatographed on silica gel and finally refined by high gravity liquid chromatography or high pressure liquid chromatography to obtain 7 kinds of saponins: 1 to 7;
