2.2.Heat treatment

The grape seeds were washed with excess water to remove adhering materials and sun-dried. Powder form of grape seeds were homogenizd with a mixer (MC-811C,Novita,Korrea) at high speed. Two forms of grape seeds (2.0g) - whole and powder forms -were placed single layer in a Pyrex Petri dish (8.0 cm dimeter) and roasted at 50,100,150 or 200度C for 10,20,30,40,60,90 or 120 min, respectively (43 treatments including contorl), in an electric muffle furnace (Mode DMF-802 , Daeil Engineering , Korea).

2.3 Prearation of 70% ethanol extracts of grape seeds

Raw or heat treated grape seeds (0.1g) were extracted overnight whit 10mL of 70%ethanol solution in a shaking incubator(100rpm) at room temperature. Then the extracts were centrifuged at 1000g for 15 min. The supernatans were filtered through a Whatman No.1 filter paper. The 70%ethanol extracts of whole(WGSE) or powder grape seeds (PGSE) were diluted 5-fold with 70% ethanol and used for the determination of antioxidant activity.

2.4. Total phenolic contents

antioxidtive and radical scavenging activity of proanthocyanidins had been reported(Ariga,Koshiyama,& Fukushima,1998;Ricardo da Silva, darmon, Fenandez,& Mitjavila,1991.These results indicated that phenolic compounds in GSE were liberated by heat treatments. Our previous studies(Jeong et al.,2004a;Jeong et al.,204b showed that simple heat treatment converted insoluble phenolic compounds to solubie phenolics but could not cleave covalently bound phenolic compounds from rice hull. This indicates that phenolic compounds of plants should present in different bound froms depend on species. Thus, effective processing step for liberating antioxidant from different plant species may not be the same.

    感謝你的迅速的答覆。  我們將讓我們的顧問知道你的名字改正並且做必要改變。  我們希望關於準備好的星期一有I-20 為上升。  2.2.熱處理 葡萄種子與過度水一起洗除去黏著材料和太陽干。  葡萄種子的粉形式是有一個混和器(兆居裡811C,Novita,Korrea)的homogenizd  以高速。  葡萄種子(2.0 克)的兩個形式  -全部和粉形式 -把單層被放在一只Pyrex Petri 盤子(8.0厘米dimeter)裡  並且在50,100,150或者200 烤 度10,20,30,40,60,90或者120分的C,分別(43種處理方法包括contorl) ,在一個電的套筒爐膛(模式DMF-802,Daeil 工程,朝鮮)裡 . 葡萄種子的70%的酒精選段的2.3 Prearation 生或者被進行熱處理的葡萄種子(0.1 克)  選出一夜70% 酒精解決辦法在一個動搖的培養訓練基地(100rpm)內10 mL是  在室溫。  然後選段被以1000 克離心分離15分。  supernatans被濾過瓦特曼紙1號濾紙。  整個(WGSE)的70%的酒精選段  或者粉葡萄種子(PGSE)  稀釋與70%的酒精一起的5倍並且用於抗氧化劑活動的決心。 2.4. 總酚的內容 清除proanthocyanidins的活動的antioxidtive和激進主義者已經被報告(Ariga,Koshiyama和Fukushima,1998; 李嘉圖‧達‧席爾瓦,darmon,Fenandez和Mitjavila,1991個.These 結果表明在GSE裡的酚的化合物被熱處理解放。  我們的以前的研究(Jeong et al.,2004a; Jeong et al.,204 b 顯示簡單的熱處理把難以解決的酚的化合物轉化成solubie phenolics,但是不能從大米殼裂開covalently 邊界的酚的化合物。  這表明植物的酚化合物在不同的邊界的froms內給取決於種類。  因此,有效處理適合解放抗氧化劑從不同植物種類走可能不相同。
