研究发现茶树种子中的皂苷部分对乙醇诱导的小鼠胃粘膜损伤有很强的保护作用,已从中分离得到9个新的三萜寡糖苷,分别命名为Assamsaponins A～Ⅰ,并运用化学和物理化学的方法对其结构进行了鉴定。 Studies have found that the saponin fraction of tea seed has a strong protective effect on alcohol-induced gastric mucosal damage in mice. Nine new triterpene glycosides have been isolated from them, which are named Assamsaponins A to I, respectively, and used in chemistry and physics. The chemical method has been characterized by its structure.
