Five sesquiterpenoid glycosides (two guaiane-type glycosides and three eudesmane-type glucosides) and a glucoside of an acetylene derivative were newly isolated from the water-soluble portion of the methanolic extract of Atractylodes lancea rhizome together with 26 known compounds. Their structures were characterized as atractyloside A 14-O-β-D-fructofuranoside, (1S,4S,5S,7R,10S)-10,11,14-trihydroxyguai-3-one 11-O-β-D-glucopyranoside, (5R,7R,10S)-isopterocarpolone β-D-glucopyranoside, cis-atractyloside I, (2R,3R,5R,7R,10S)-atractyloside G 2-O-β-D-glucopyranoside, and (2E,8E)-2,8-decadiene-4,6-diyne-1,10-diol 1-O-β-D-glucopyranoside on the basis of chemical and spectroscopic investigation. The presence of six characteristic guaiane-type glucosides in both rhizomes of A. lancea and Atractylodes japonica suggested a close chemotaxonomic relationship between them.
从白术根茎甲醇提取物的水溶性部分中新分离出五种倍半萜苷(两种愈创木苷和三种桉叶烷苷)和一种乙炔衍生物苷,以及 26 种已知化合物。它们的结构特征是白术苷 A 14-O-β-<小>D小>-呋喃果糖苷、(1S,4S,5S,7R,10S)-10,11,14-三羟基愈创木-3-酮 11-O-β-<小>D小>-吡喃葡萄糖苷、(5R,7R,10S)-异翅果萜酮β-<小>D小>-吡喃葡萄糖苷、在化学和光谱研究的基础上,还发现了顺式白术苷 I、(2R,3R,5R,7R,10S)-白术苷 G 2-O-β-<小>D小>-吡喃葡萄糖苷和(2E,8E)-2,8-癸二烯-4,6-二炔-1,10-二醇 1-O-β-<小>D小>-吡喃葡萄糖苷。白术根茎和白术根茎中均含有六种特征性瓜蒌苷,这表明它们之间存在密切的化学分类学关系。
