Methods The activitie of anti-lipidperoxidation of Chinemys Plastrum Testudinis of petroleum-ether, acetoacetate and 95% alcohol solution from two producing areas was studied by DPPH.

方法采用DPPH法分别测定两种不同产地龟板的石油醚、乙酸乙酯、95％乙醇等不同极性溶剂提取物的抗氧化活性。

Ointment extracted from Plastrum Testudinis was separated by silica gel column chromatography, gradiently eluted by petroleum ether-ethyl acetate, and 16 (Ts-1～Ts-16) components were obtained, which were biologically evaluated by MTT assay and flow cytometry on the proliferation of rat marrow-derived mesenchymal stem cells. Results showed that Ts-12 induced proliferation compared with the control group ( p ＜0.05), while Ts-4 showed inhibitive effect. Other groups showed no significance ( p ＞0.05). GC-MS was used to analyze the chemical components in different groups.

中药龟板提取物浸膏经硅胶柱层析，用石油醚-乙酸乙酯作洗脱剂，梯度洗脱，得到16个组分；采用MTT法和流式细胞技术研究了它们对鼠骨髓间充质干细胞的增殖作用，实验结果显示组分Ts-12具有促进rMSCs增殖的作用( p ＜0.05)，而组分Ts-4则表现出抑制rMSCs增殖的作用( p ＜0.05)，其它样品对rMSCs的增殖作用不显著( p ＞0.05)，不具统计学意义。
