摘　　要：为了探究药食两用中药膳食纤维的生理活性,选择党参、黄芪、山药、甘草、灵芝、人参、西洋参七种药食两用中药制备了水溶性膳食纤维(soluble dietary fiber,SDF)、非水溶性膳食纤维(insoluble dietary fiber,IDF)和总膳食纤维(total dietary fiber,TDF),并对其体外抗氧化活性和胆酸盐结合能力进行了研究。结果表明:七种膳食纤维成分的理化性质和体外活性存在显著差异。党参、灵芝和人参TDF分别具有最高的持水性(11.26 g/g),持油性(6.36 g/g)和溶胀性(9.12 mL/g)。黄芪SDF、山药SDF和西洋参TDF分别具有最高的DPPH自由基清除率(96.27%),羟自由基清除率(97.20%)和超氧阴离子自由基清除率(60.32%),人参TDF的总抗氧化能力最强(2283.39μmol/L/FeSO_(4))。人参TDF对甘氨胆酸钠结合率最高(59.87%),黄芪TDF对牛磺胆酸钠结合率最高(51.52%),七种药食两用中药膳食纤维对甘氨胆酸钠的平均结合率(34.12%~53.73%)高于对牛磺胆酸钠的平均结合率(28.16%~45.47%)。本研究证实了党参等七种药食两用中药膳食纤维具有良好的理化性质和生理活性,具有功能性食品的开发潜力。The objective of this study was to explore the biological activity of dietary fiber in edible traditional Chinese medicines.Seven Chinese medicines(Codonopsis pilosula,Astragali radix,Chinese yam,liquorice,Ganoderma lucidum,Panax ginseng,Panax quinquefolium)were chose to extract the water-soluble dietary fiber(soluble dietary fiber,SDF),water-insoluble dietary fiber(insoluble dietary fiber,IDF)and total dietary fiber(total dietary fiber,TDF).The physicochemical properties,in vitro antioxidant activity and bile salts binding ability of dietary fibers were studied.The results showed that the Codonopsis pilosula TDF,Ganoderma lucidum TDF and ginseng TDF had the highest waterholding capacity(11.26 g/g),oil-holding capacity(6.36 g/g)and swelling capacity(9.12 mL/g),respectively.Astragali radix SDF,Chinese yam SDF and ginseng TDF had the highest DPPH scavenging rate(96.27%),hydroxyl radical scavenging rate(97.20%),and the superoxide anion radical scavenging rate(60.32%),respectively.Ginseng TDF had the highest total antioxidant capacity(2283.39μmol/L/FeSO_(4)).Ginseng TDF had the highest binding rate to sodium glycinate(59.87%),Astragali radix TDF had the highest binding rate to sodium taurocholate(51.52%).The average binding rate of dietary fibers to sodium glycosyl cholate(34.12%~53.73%)were higher than that of sodium taurocholate(28.16%~45.47%).This study shows that seven edible traditional Chinese medicines had good physicochemical properties and biological activity,which give them development potential of functional food.
