摘要
滇南红厚壳叶经甲醇浸提并浓缩得浸膏,提取浸膏再用石油醚萃取.石油醚溶解部位经硅胶柱层析,石油醚-乙酸乙酯作为洗脱剂梯度洗脱,获得4个化合物,其中在石油醚-乙酸乙酯体积比为9:1的洗脱条件下首次从该植物中分离得到一种白色柱状晶体.经IR,MS,1HMNR和13CMNR以及X射线单晶衍射对分离化合物进行结构表征,确定所获化合物1为木栓内酯.采用MTT法研究了木栓内酯诱导小鼠骨髓间质干细胞的增殖活性,显示出一定的促进作用.
The methanol extract of the dried leaf of Calophyllum polyanthum was partitioned successively with petroleum ether and ethyl acetate.Petroleum ether fraction was gradient eluted over silica gel column using 9：1 petroleum ether-ethyl acetate as eluant to give a rod crystal and three known compounds.The rod crystal was characterized by IR,1H NMR,13C NMR,MS and X-ray single crystal diffraction.The results showed that the crystal was friedelin-3,4-lactone,and the molecular formula was C30H50O2.Its bioactivity was measured by MTT assay.The results proved that triterpenoid lactone has a promotion effect on the inducing proliferation of rat mesenchymal stem cells（rMSCs）.
