摘要: 从搭棚藤(Porana discifera Schneid )分离到10个植物蜕皮激素,它们分别是β-蜕皮激素(1)及其2-乙酸酯(2)、3-乙酸酯(3)、25-乙酸酯(4)、2,3-异丙亚二氧基β-蜕皮激素(5)、20,22-异丙亚二氧基β-蜕皮激素(6)、2-去氧β-蜕皮激素(7)、2-去氧-20,22-异丙亚二氧基β-蜕皮激素(8)、2-去氧β-蜕皮激素-3-葡萄糖甙(9)和甲基暗红牛漆甾酮(posterone,10)。化合物8和9的碳谱系首次报道。昆明小鼠的体内活性测定表明,化合物1~7没有镇静、镇痛、抗惊厥、抗炎以及抗脑缺氧方面的活性。

Abstract: From the aerial parts of Parana discifera, 10 phytoecdysones, β- ecdysterone (1) and its 2 -acetate (2) , 3 - acetate (3), 25 - acetate (4) ,2,3- acetonide (5) , 20, 22 - acetonide (6) , and 2 -deoxyecdysterone (7) and its 20, 22 - acetonide (8), 3-O-β-D- glucopyranoside (9) and posterone (10) were isolated. They have no anti - inflammatory, analgesic, sedative, anti - convulsant and anti -cerebra- hypoxic activities in animal testing with Kunming mice.
