目的：依照国家食品药品监督管理总局（CFDA）制定的黄芪注射液与红花注射液的制备方法，分别对黄芪与红花进行相关提取。研究黄芪、红花提取物抑制α-葡萄糖苷酶及抗氧化活性的最佳配比。方法液相色谱仪测定黄芪中黄芪甲苷的含量，以山奈酚为标准品测定红花中总黄酮的含量。以4-甲基-伞形酮-β- D -半乳糖苷（4- MUG）为反应底物，测定样品对酵母α-葡萄糖苷酶活性的影响，阿卡波糖为阳性对照。以氧自由基清除能（ Oxygen Radical Absorbance Capacity， ORAC）法测定样品的抗氧化活性，维生素 C 为阳性对照。结果每1 ml 黄芪提取液中含有0.127 mg黄芪甲苷，每1 ml 红花提取液中含0.57 mg 总黄酮，均符合 CFDA 有关活性成分的含量要求。红花抑制α-葡萄糖苷酶活性的半数抑制浓度（IC50）为（32.8±5.7）μg/ ml，显著低于黄芪[（1686±810）μg/ ml，P <0.01]；黄芪与红花生药比为10：1、5：1、2：1时的 IC50值均显著低于20：1时（P <0.01）。红花的 ORAC 值为（1090±161）μmol TE/ g，显著高于黄芪[（205±32）μmol TE/ g，P <0.01]；生药比为5：1及2：1时的 ORAC 值分别显著高于20：1及 10：1时（P <0.01）。结论黄芪与红花均具有抑制酵母α-葡萄糖苷酶活性的作用及一定的抗氧化活性，在同时改善以上两项指标方面，生药比为5：1及2：1时较20：1时作用显著（P <0.01）。

Objective To prepare radix astragalus injection and flos carthami injection according to the method of the China Food and Drug Administration(CFDA)and extract them respectively so as to study the optimum proportion of them on alpha - glucosidase and antioxidant activities. Methods The liquid chro-matograph was used to determine the content of astragaloside in radix astragalus. Kaempferol was used as the standard to determine the content of general flavone in flos carthami. 4 - MUG was as the oligomer to deter-mine the impacts of the samples to yeast alpha glycosidase enzyme activity,in which,acarbose was taken as the positive control. Oxygen radial absorbance capacity(ORAC)was adopted to determine the antioxidant ac-tivity of samples,in which,vitamin C was taken as the positive control. Results The astragaloside 0. 127 mg contained in each 1 ml radix astragalus extraction and the general flavone 0. 57 mg in each 1 ml flos carthami extraction. All of them met the content requirement of CFDA - relevant activity component. IC50 of the inhibi-tion of flos carthami for alpha - glucosidase activity was(32. 8 ± 5. 7)μg/ ml,significantly lower than that of radix astragalus[(1686 ± 810)μg/ ml,P < 0. 01]. IC50 was lower significantly at the ratios of radix astragalus and flos carthami as 10: 1,5: 1 and 2: 1 as compared with that at the ratio of 20: 1(P <0. 01)separately. ORAC value of flos carthami was(1090 ± 161)μmol TE/ g,higher significantly than that of radix astragalus[(205 ± 32)μmol TE/ g,P <0. 01]. When the ratios of the crude herbal materials were 5: 1 and 2: 1,ORAC value was higher significantly than that at 20: 1 and 10: 1 respectively(P <0. 01). Conclusion Both radix astragalus and flos carthami act on the inhibition of yeast alpha - glucosidase activity and has a certain of antioxidant activity. While improving the above indexes,the actions of the crude herbal materials are significant at the ratio of 5:1 and 2: 1 as compared with those at 20: 1(P < 0. 01).
