| 摘要: |
| 以5种不同来源的α-淀粉酶为检测试剂,对鹰嘴豆种胚芽和子叶α-淀粉酶抑制剂在发芽和成熟过程中的抑制活性进行测定。结果表明:α-淀粉酶抑制剂主要存在于胚芽中; 发芽过程中,发芽1 d后,胚芽提取液对AOA的抑制活性降为9.9%,而对HSA、PPA和PA的抑制活性都检测不到。子叶提取液对AOA和HSA的抑制活性分别降为21.5%和28.3%,而对BSA和PPA则检测不到活性。发芽4 d后,无论是子叶还是胚芽提取液对5种来源的α-淀粉酶都检测不到抑制活性; 种子成熟过程中,子叶和胚芽提取液对α-淀粉酶的抑制活性均随种子成熟度的提高而提高,30 d时达到最大,且胚芽提取液对HSA、PA的抑制活性较高,分别为48.9%和47.5%。 |

| Abstract: |
| Inhibitory activity of α-amylase from chickpea seeds(embryo and cotyledon)during germination and maturation against α-amylase derived from 5 different sources were determined. The results showed that α-amylase inhibitor mainly exists in the embryo. During germination,1 d after germination,inhibitory activity of embryo extracts reduced to 9.9% against AOA,and there was no inhibitory activity to HSA,PPA and PA; inhibitory activity of cotyledon extracts against AOA and HSA reduced to 21.5%,28.3%,respectively,and there was no inhibitory activity to BSA and PPA. 4 d after germination,both cotyledon and germ extracts on 5 sources were undetectable inhibitory activity. During seed maturation,both cotyledon and embryo extracts on the activity of α-amylase inhibitor increased with the days of seed maturity and reached to the maximum on 30 d,and the inhibitory activity of embryo extract was higher on HSA and PA,48.9% and 47.5%,respectively. |
