| 选取黑芝麻和白芝麻各3个品种，研究黑、白芝麻籽、仁及皮的总酚、木脂素含量和抗氧化活性以及总酚、木脂素含量、抗氧化活性之间的相关性。结果表明：黑芝麻籽、仁及皮的总酚含量均高于白芝麻籽、仁及皮；黑芝麻和白芝麻各品种间芝麻籽、芝麻仁及芝麻皮中木脂素含量变化不大，且芝麻素和芝麻林素含量均较低（<40 mg/100 g）；黑芝麻籽及黑芝麻皮的总抗氧化能力均高于白芝麻籽及白芝麻皮，而黑、白芝麻仁的总抗氧化能力相差不大；黑、白芝麻皮对DPPH·清除率均显著高于芝麻籽及芝麻仁；黑、白芝麻籽及芝麻仁对·OH均表现出很弱的清除能力，而芝麻皮对·OH清除率均在60%以上；黑、白芝麻籽及芝麻皮总酚与总抗氧化能力呈极显著正相关（P<0.01），与DPPH·清除率呈极显著（P<0.01）或显著（P<0.05）正相关。 |
| 英文摘要: |
| Three varieties of black sesame and three varieties of white sesame were selected to study the contents of total phenolics, lignans and antioxidant activity of seed, kernel and seed coat, and the correlation between total phenolics, lignans and antioxidant activity. The results showed that the total phenolics contents in black sesame seed, kernel and seed coat were higher than those in white sesame seed, kernel and seed coat. The lignans contents in sesame seed, kernel and seed coat of black sesame and white sesame varieties changed little, and the contents of sesamin and sesamolin were lower (<40 mg/100 g). The total antioxidant capacity of black sesame seed and seed coat were higher than those of white sesame seed and seed coat, while the total antioxidant capacity of black sesame kernel and white sesame kernel had little difference. The DPPH free radical scavenging rates of seed coats of black sesame and white sesame were much higher than those of sesame seed and kernel, and the hydroxyl free radical scavenging abilities of sesame seed and kernel of black sesame and white sesame were very weak, but the hydroxyl free radical scavenging rate of sesame seed coat was above 60%. Total phenolics contents and total antioxidant capacities of seed and seed coat of black sesame and white sesame were extremely, significantly and positively correlated (P＜0.01), and the total phenolics contents of seed and seed coat were extremely and significantly (P＜0.01) or significantly(P＜0.05)positively correlated with DPPH free radical scavenging rate. |
