giganteum could significantly prolong the survival time of myocardial hypoxia mice, fractions eluted by 50% EtOH in NKA-9 type macroporous resin could significantly prolong the survival time in myocardial hypoxia mice, but also to improve the biochemical indicators of myocardial ischemia mice, so extraction process using 60% EtOH should be a more reasonable extraction method, the eluted material with 50% EtOH in macroporous resin should be the active friction.
