Abstract

The invention provides a discorea nipponica makino extractive and application thereof in preparing medicaments for resisting free radicals and reducing blood fat. The discorea nipponica makino extractive is obtained by extracting discorea nipponica makino medicinal materials with an alcoholic solution and then extracting with chloroform and normal butanol. The discorea nipponica makino extractive comprises steroidal compounds, phytosterol and benzylacid, and has better activity for reducing fat, resisting coagulation and resisting free radicals. The extractive can be further separated and purified by adopting silicagel column chromatography, oxide dispersion strengthened (ODS) meslow column chromatography and semi-preparation high performance liquid chromatography (HPLC). The steroidal compounds comprise diosgenin, dioscin, prosapogenin and trillin which all have better activity for reducing fat, resisting coagulation and resisting free radicals and are effective components of discorea nipponica makino for reducing blood fat, wherein the effects of the dioscin and the prosapogenin are more remarkable.
