摘　　要：红薯中含有大量的活性成分,如去氢表雄酮(DHEA)。DHEA具有抗氧化,抗糖尿病,抗肿瘤的潜在功能。因此,DHEA对人体健康至关重要。该研究以薯皮为原料,采用绿色环保的超声波辅助提取法,提取薯皮中DHEA,将薯皮变费为宝。将鲜红薯皮预发酵,并用浓硫酸进行酸解,然后中和;超声波提取DHEA,减压浓缩;最后,通过HPLC定性分析,定量检测。There are many active ingredients in sweet potatoes,such as dehydroepiandrosterone(DHEA).DHEA plays an important role in human health owning to the potential function of antioxidant,anti-diabetes and anti-tumor.In the study,we turn waste into wealth by extracting of DHEA from fresh sweet potato skin as raw material using the green method of ultrasonic-assisted extraction.The fresh sweet potatoes skin were prefermented.Then,sulfuric acid was employed for acidolysis,followed by neutralization.Ultrasound was employed to extract DHEA and vacuum concentration.Finally,it was detected by HPLC with quantify and qualitative analysis.
