为研究草果药根茎中具有抗神经炎症作用的活性成分, 运用包括MCI柱色谱、硅胶柱色谱以及半制备高效液相色谱等多种分离手段, 从草果药根茎中共分离得到4个化合物, 并通过高分辨质谱、核磁共振和电子圆二色谱(ECD)等技术将其鉴定为(10R,11E)-6-羟基-15,16-二降-半日花烷-5,8,11-三烯-7,13-二酮(1)、(5S,9S,10R,11E)-14,15,16-三降-半日花烷-7,11-二烯-6-酮-13-羧酸甲酯(2)、(11E)-15,16-二降-半日花烷-7,11-二烯-6,13-二酮(3)、(11E)-6α-羟基-15,16-二降-半日花烷-8(17),11-二烯-13-酮(4), 其中化合物12为新化合物. 利用脂多糖诱导的神经小胶质细胞(BV2)模型评价这4个化合物的抗神经炎症作用, 结果表明4个化合物均能够抑制脂多糖诱导的NO生成, 表现出抗神经炎症作用; 测得化合物1~4抑制NO生成的C50值分别为(17.12±5.59), (28.66±7.82), (22.24±8.02)和(16.81±5.62) μmol/L.

This study aimed to investigate the chemical constituents with anti-neuroinflammation effect from Hedychium spicatu rhizomes in which four compounds were isolated by various chromatographic techniques, such as MCI and silica gel column chromatography and semi-preparative high performance liquid chromatography. They were identified by high reso- lution mass spectrometry, nuclear magnetic resonance, and electronic circular dichroism (ECD) methods as (10R,11E)-6- hydroxy-15,16-bisnor-labda-5,8,11-triene-7,13-dione (1), (5S,9S,10R,11E)-14,15,16-trinor-labda-7,11-diene-6-one-13-acid me- thyl ester (2), (11E)-15,16-bisnor-labda-7,11-diene-6,13-dione (3), (11E)-6α-hydroxy-15,16-bisnor-labda-8(17),11-diene-13- one (4). Compouns 1 and 2 are two new nor-labdane diterpenoids. Their anti-neuro-inflammatory effects were evaluated via lipopolysaccharide (LPS) induced mouse microglial (BV2) cells. The results showed that the four compounds could inhibit the production of NO induced by LPS to displayed anti-neuroinflammatory effect. The IC50 values of compounds 1~4 were (17.12±5.59), (28.66±7.82), (22.24±8.02), and (16.81±5.62) μmol/L, respectively.
