摘要: 采用多种层析方法从广东桑根心材的醇提取物中分离了8个已知化合物,经波谱分析手段结合文献分析方法将其分别鉴定为:桑辛素C(1),桑辛素 M(2),二氢桑色素(3),氧化白藜芦醇(4),2,4二羟基苯甲醛(5),伞形花内酯(6),胡萝卜苷(7)和3-羟基-2-哌啶酮(8)。化合物1,3~6和8首次从广东桑Morus atpropurpurea 中分离,化合物8亦首次从桑属植物中分离。综合采用DPPH,MTT法测试了多酚类化合物1~4的抗氧化和神经保护作用,结果表明化合物1~4均能清除DPPH自由基,抑制L-谷氨酸钠诱导海马神经元细胞HT22毒性,具有抗氧化和神经保护作用。在20 μM浓度下,化合物2的活性显著。

Abstract: Eight known compounds,including Moracin C(1),Moracin M(2),Dihydromorin(3),Oxyresveratrol(4),2,4-Dihydroxybenzaldehyde(5),7-Hydroxycoumarin(6),Daucosterol(7) and 3-Hydroxy-2-piperidinone(8)have been isolated from EtOH extract of heartwood of root of Morus atpropurpurea.Compounds 1,3-6 and 8 were isolated from Morus atpropurpurea for the first time.Compound 8 was also isolated from Morus plant for the first time.Their antioxidant and neuroprotective activity were test by DPPH,MTT methods.Polyphenolic compounds 1-4 exhibited antioxidative and neuroprotective activitives.Compound 2 showed significant neuroprotective activity at 20 μM.

Key words: Morus atpropurpurea, heartwood, chemical ingredients, neuroprotection, antioxidation
