银背风毛菊 Saussurea nivea Turcz. 为菊科风
毛菊属植物,主要分布于东北及内蒙古自治区等
地。民间用于治疗感冒、头痛、关节炎和扭伤[1-2]。
国内外对该植物的化学成分研究报道[3]较少。为从
银背风毛菊中寻找新的生物活性成分,对采自河南
省桐柏山的银背风毛菊全草进行了化学成分研究。
应用色谱分离技术及重结晶等方法对化合物进行
分离,并运用现代波谱技术(1H-NMR、13C-NMR、
EI-MS 等)鉴定化合物结构。从其丙酮提取物中分
离鉴定了 11 个三萜类化合物,分别是 20(30)-烯-3β-
羟基蒲公英烷(蒲公英甾醇,taraxasterol,1)、20-
烯 -3β-羟基蒲公英烷(pseadotaraxasterol,2)、
1β-hydroxy-ursa-9(11), 12(13)-dien-3β-yl palmitate
(ussuriensin A,3)、1β-hydroxy-oleana-9(11), 12-dien-
3β-yl palmitate(ussuriensin B,4)、21α-hydroxyl-
taraxasterol(5)、20(30)-烯-21α, 22α-环氧-3β-蒲公英
醇( ptiloexp-oxide , 6 )、 12-ursene-3β, 11α-diol
3-O-palmitate( 7)、 9(11), 12-ursadien-3β-ol 3-O-
palmitate(8)、bauereny lacetate(9)、3β-hydroxy-
11-oxo-olean-12-enyl palmitate(10)、3β-hydroxy-11α,
12α-epoxy-friedo-olean-14-enyl palmitate(11)。所有
化合物均为首次从银背风毛菊中分离得到,其中化
合物 7~11 为首次从风毛菊属植物中分离得到。
