从藤山柳 [Clematoclethra scandens( Franch.) Maxim.]根茎甲醇提取物的石油醚和乙酸乙酯部分分离出 8个化合物 ,经理化常数和波谱分析 ,分别鉴定为 :7-羰基贝壳杉烯内酯 ( 1) ,蒲公英赛烷醇 ( 2 ) ,桦木酸 ( 3) ,乌苏酸 ( 4 ) ,2 α,3α,2 3-三羟基乌苏 - 12 -烯- 2 8-酸 ( 5) ,2 α,3α,2 3-三羟基乌苏 - 12 ,2 0 ( 30 ) -二烯 - 2 8-酸 ( 6) ,豆甾 - 4 -烯 - 3,6-二酮 ( 7)和β-谷甾醇 ( 8)。以上化合物均为首次从该属植物中获得。 Eight compounds were isolated from the petroleum ether and ethyl acetate fractions of the methanol extract of Clematocleth scandens (Franch.) Maxim. from the roots of Fujiyama Willow, and were analyzed by the managerial constants and spectroscopic analysis. They were identified as: 7-carbonyl kafene lactone. (1) , Taraxacum (2), Betulinic Acid (3), Ursolic Acid (4), 2α, 3α, 2 3-Trihydroxy-Usu-12-12-ene-2-O-Acid (5), 2 α,3α,2 3-trihydroxywusu-12,20 (30)-dien-2-carbanilic acid (6), soybean pod-4-ene-3,6-dione (7) and β - sitosterol (8). All of the above compounds were obtained from this genus for the first time.
