查询词典 gel

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.
