摘要:

对藤黄科金丝桃属植物糙枝金丝桃Hypericum scabrum地上部分的化学成分进行了研究。利用多种色谱技术从糙枝金丝桃乙醇提取物中分离得到了10个间苯三酚类成分,包括1个新化合物,命名为hyperibrin H(1);其他化合物被分别鉴定为 hypermongone A(2)、hypermongone E(3)、hypermongone F(4)、hypermongone G(5)、hypermongone H(6)、sampsonione L(7)、garcinielliptone I(8)、propolone C(9)、garcinielliptone N(10)。化合物2~10均为首次从该植物中分离得到。化合物56在10 μM浓度下对谷氨酸诱导的神经元损伤具有保护作用。

Abstract:

To study the chemical constituents from the aerial part of Hypericum scabrum, ten polyprenylated acylphloroglucinol derivatives were isolated from the ethanol extract of H. scabrum,including a new compound hyperibrin H (1).The other compounds were elucidated as:hypermongone A (2),hypermongone E (3),hypermongone F (4),hypermongone G (5),hypermongone H (6),sampsonione L (7),garcinielliptone I (8),propolone C (9),and garcinielliptone N (10).Compounds 2-10 were isolated from this plant for the first time.Compounds 5 and 6 showed neuroprotective activity against glutamate-induced toxicity in SK-N-SH cells at 10 μM.

Key words: Hypericum scabrum, polyprenylated acylphloroglucinol, neuroprotective activity
