A total of fourteen (14) species of wild edible fruits from Burkina Faso were analyzed for their phenolic and flavonoid contents, and their antioxidant activities using the DPPH, FRAP and ABTS methods. The data obtained show that the total phenolic and total flavonoid levels were significantly higher in the acetone than in the methanol extracts.Detarium microcarpum fruit had the highest phenolic and the highest flavonoid content,followed by that of Adansonia digitata, Ziziphus mauritiana, Ximenia americana and Lannea microcarpa. Significant amounts of total phenolics were also detected in the other fruit species in the following order of decreasing levels: Tamarindus indica > Sclerocaryabirrea > Dialium guineense > Gardenia erubescens > Diospyros mespiliformis > Parkiabiglobosa > Ficus sycomorus > Vitellaria paradoxa. Detarium microcarpum fruit also showed the highest antioxidant activity using the three antioxidant assays. Fruits with high antioxidant activities were also found to possess high phenolic and flavonoid contents. There was a strong correlation between total phenolic and flavonoid levels and antioxidant activities.
对来自布基纳法索的14种野生可食用水果进行了分析，测定其酚类和黄酮类化合物含量，并采用DPPH法、FRAP法和ABTS法测定其抗氧化活性。所得数据表明，丙酮提取物中的总酚和总黄酮水平显著高于甲醇提取物。小果厚皮树果实的酚类和黄酮类含量最高，其次是猴面包树、毛里求斯枣、美洲西门木和小果榄仁。其他水果品种中也检测到大量总酚，含量由高到低依次为：罗望子>硬核油桃木>几内亚猴欢喜>栀子>柿叶柿>大果油楠>无花果>奇异果。小果厚皮树果实通过三种抗氧化试验也显示出最高的抗氧化活性。抗氧化活性高的水果也具有较高的酚类和黄酮类含量。总酚和黄酮水平与抗氧化活性之间存在很强的相关性。
