摘　　要：目的:以火山粉葛为原料,以铁皮石斛、麦芽糊精、木糖醇、海藻酸钠为辅料制成粉葛冲调粉。方法:通过单因素和L_(9)(3^(4))正交试验,采用综合评分法确定粉葛冲调粉的最优配方。以DPPH·自由基清除能力、ABTS^(+)·自由基清除能力确定粉葛冲调粉总抗氧化能力,以α-葡萄糖苷酶抑制活性试验确定粉葛冲调粉体外降糖作用。结果:粉葛冲调粉的最优配方为原料配比粉葛:铁皮石斛1:0.2、麦芽糊精10%、木糖醇0.3%、海藻酸钠0.3%,综合评分为84.65分。粉葛冲调粉与抗坏血酸(维生素C)清除ABTS^(+)·自由基的IC_(50)值分别为(3.909±0.975)、(0.2009±0.0849)mg/mL;粉葛冲调粉与抗坏血酸清除DPPH·自由基的IC_(50)值分别为(3.860±1.094)、(0.1269±0.0755)mg/mL;粉葛石斛组与抗坏血酸在浓度为1.5 mg/mL时,总抗氧化能力分别为0.1811、0.499。粉葛冲调粉与阿卡波糖对α-葡萄糖苷酶抑制活性的IC_(50)值分别(5.845±3.353)、(0.371±0.0477)mg/mL。结论:研制出一款新型粉葛冲调粉产品,可提高粉葛经济价值,为粉葛冲调粉产业化生产提供科学依据。【Objective】With volcanic Pueraria thomsonii Benth as raw material,Dendrobium officinale,maltodextrin,xylitol and sodium alginate as excipients,Pueraria thomsonii mixing powders was prepared.【Method】Through single factor and L_(9)(3^(4))orthogonal experiment,the optimal formula of Pueraria thomsonii mixing powders was determined by comprehensive scoring method.The total antioxidant capacity of the powders was determined by DPPH·free radical scavenging ability and ABTS^(+)·free radical scavenging ability.The hypoglycemic effect of powders in vitro was determined by the inhibitory activity test of α-glucosidase.【Result】The optimal formula of the powder was the ratio of raw materials(Pueraria thomsonii:Dendrobium officinale)1:0.2,maltodextrin 10%,xylitol 0.3%,sodium alginate 0.3%,and the comprehensive score was 84.65 points.The IC_(50) values of scavenging ABTS^(+)·free radicals by Puerariae thomsonii mixing powders and ascorbic acid were(3.909±0.975)and(0.2009±0.0849)mg/mL,respectively.The IC_(50) values of DPPH·free radi⁃cal scavenging of Pueraria thomsonii mixing powders and ascorbic acid were(3.860±1.094)and(0.1269±0.0755)mg/mL,respectively.The total antioxidant capacity of Puerariae thomsonii mixing powders and ascorbic acid at a concentration of 1.5 mg/mL was 0.1811 and 0.499,respectively.The IC_(50) values of α-glucosidase inhibitory activity of Pueraria thomsonii mixing powders and acarbose were(5.845±3.353)and(0.371±0.0477)mg/mL,respectively.【Conclusion】A new powder blending product of Pueraria thomsonii was developed to improve its economic value.
