| BACKGROUND: Unstable generation of free radicals in the body are responsible for many degenerative diseases. A bloom forming algae Euglena tuba growing abundantly in the aquatic habitats of Cachar district in the state of Assam in North-East India was analysed for its phytochemical contents, antioxidant activity as well as free radical scavenging potentials. RESULTS: Based on the ability of the extract in ABTS+ radical cation inhibition and Fe3+ reducing power, the obtained results revealed the prominent antioxidant activity of the algae, with high correlation coefficient of its TEAC values to the respective phenolic and flavonoid contents. The extract had shown its scavenging activity for different free radicals and 41.89 ± 0.41... |

| 30種の種子に含まれるポリフェノール含量と1,1-dipheny-2-picrylhydrazyl(DPPH) 消去活性、 還元力および百粒重、種皮色との関連性について検討した。30種の種子のポリフェノール含量とDPPH 消去活性および還元力との間には、それぞれ高い正の相関関係のあることを明らかにした。 また、赤色系種子のみ明度(L*値)、赤味度(a*値)、黄味度(b*値)、彩度(C*値) とポリフェノール含量との間にそれぞれ高い正の相関性のあること、茶、黄色系種子ではL*値とポリフェノール含量との間に高い負の相関性のあることを明らかにした。調査した種子の中でレンゲ、アカクローバ(メジウム)、ダッタンソバ、ナタネはポリフェノール含量が高いが、百粒重は小さい。 手亡、黒金時、白小豆、アカネ大納言、ユキシズカ、ヘアリーベッチ、アワ、ヒエ、蕎麦、黒ゴマのポリフェノール含量と百粒重はともに低い値であった。 Thirty kinds of seeds, we concerning the correlation of polyphenol content and DPPH radical scavenging, reducing power, weight of hundred seeds, coat color. We found positive correlation between polyphenol content and DPPH radical scavenging, reducing power in 30 kinds of seeds, respectively. In the present investigation, there are positive correlation with... |
