				        	Object  To study on the structure of sapogenins from pod of Gleditsia sinensis Lam   Methods  Pod of G. sinensis  was extracted with solvents and the constituents in the extraction isolated, after hydrolised completely, with the aid of flash chromatography to obtain 2 gledgenins   Results  The structures of the 2 gledgenins were proved to be 3  hydroxy  12  oleanen  28  oic acid and 3, 16  dihydroxy  12  oleanen  28 oic acid respectively as shown by IR, NMR, MS and crystallographic data   The structures were further verified by acylation, methylation and followed by reaction with 3, 5  dinitro  benzoyl chloride   Conclusion  New crystalline derivatives were obtained to provide further evidence of their structures
