NMR studies of pentacyclic triterpenoids of oleanane type from Glycyrrhiza Yunnansis 云南甘草中齐墩果烷型五环三萜化合物的NMR谱的研究
The present of oleanane is related to the humic organic of terrestrial facies. 奥利烷的出现与陆相腐殖型母质有关。
It is noticed that oleanane triterpenoidal saponins are characteristic constituents of this family and have taxonomic significance. 结果表明齐墩果烷型三萜皂甙作为木通科的特征化学成分在该科的系统分类中具有一定的意义。
RESULTS: Tubeimosides ⅰ, ⅱ, and ⅲ are all natural analogues of oleanane type of triterpenoid saponins from the same medicinal plant, and all show anti-inflammatory, antitumor, and antitumor-promoting effects. 结果:土贝母苷Ⅰ、Ⅱ和Ⅲ是来自同一植物的齐墩果烷型三萜皂苷天然类似物。实验证实,它们都具有抗炎、抗瘤和抗促瘤效果。
