For this purpose, different formulations of Aloe vera based coating （non-poisonous） was applied at concentration of 0, 0.1%, 0.5%, and 1.0%, respectively on eggplants. The coated eggplants were stored at two different temperatures [10℃ and （30±2）℃] and examined for weight loss, firmness, stem color, shriveling, total soluble solids, pH, acidity, vitamin C, sugar （total sugar, reducing sugar and non-reducing sugar） and N, P, K, Ca and Na for two weeks. The obtained results showed that weight loss, shriveling, total soluble solids, pH, sugar （total sugar and non-reducing sugar） increased and firmness, stem color, acidity, reducing sugar, vitamin C minimized during the storage period. The 0.5% Aloe coating at 10℃ showed significant effect and delayed the changes in above parameters. Aloe vera coating remained almost ineffective in altering nutrient homeostasis （N, P, K, Ca and Na） of eggplants. The optimistic results gained in the current study could additionally investigate in larger market experiments and also could extensive to other tropical/subtropical fruits and vegetables.展开更多
分别以库拉索芦荟(Aloe barbadensis Mill.)和中华芦荟(Aloe vera L.var.Chinesis)老叶、中叶、嫩叶的整个叶片及叶片中间凝胶部分为样品,比较2种芦荟不同部位的抗氧化酶活性。结果表明,库拉索芦荟、中华芦荟不同部位抗氧化酶间活性差...分别以库拉索芦荟(Aloe barbadensis Mill.)和中华芦荟(Aloe vera L.var.Chinesis)老叶、中叶、嫩叶的整个叶片及叶片中间凝胶部分为样品,比较2种芦荟不同部位的抗氧化酶活性。结果表明,库拉索芦荟、中华芦荟不同部位抗氧化酶间活性差异较大。库拉索芦荟超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、过氧化物酶(POD)活性最高部位分别是老叶中间凝胶、中叶整个叶片、老叶整个叶片;中华芦荟SOD、CAT、POD活性最高部位分别是嫩叶中间凝胶、老叶整个叶片、老叶整个叶片。结合生物学产量,开发应用SOD方面,应以2种芦荟中叶中间凝胶为原料;开发应用CAT和POD方面,应以2种芦荟老叶整个叶片为原料。展开更多
