The aim of this study was to assess the level of some phytochemicals in 19 raspberry cultivars grown in Lithuania. The content of total ellagic acid measured after 20h acidic hydrolysis of investigated raspberry cultivars, varied from 119.8 (cv. 'Pokusa') to 323.5mg/100g (cv. 'Bristol'). The content of total phenolics ranged from 278.6 (cv. 'Pokusa') to 714.7mg/100g (cv. 'Bristol'). The total anthocyanins content varied from 2.1 (yellow cv. 'Beglianka') to 325.5mg/100g (black cv. 'Bristol'). The radical scavenging capacity of the tested raspberry cultivars highly correlating with their total phenolics and total ellagic acid content (r=0.90 and 0.92, respectively). The results of this study expand the knowledge about variation in the content of valuable bioactive compounds in raspberries and may help for the selection and validation of the most productive cultivars.
本研究的目的是评估立陶宛种植的19个树莓品种中某些植物化学物质的含量。对所研究的树莓品种进行20小时酸性水解后测得的总鞣花酸含量,从119.8mg/100g(品种‘Pokusa’)到323.5mg/100g(品种‘Bristol’)不等。总酚含量范围为278.6mg/100g(品种‘Pokusa’)至714.7mg/100g(品种‘Bristol’)。总花青素含量从2.1mg/100g(黄色品种‘Beglianka’)到325.5mg/100g(黑色品种‘Bristol’)不等。所测试的树莓品种的自由基清除能力与其总酚和总鞣花酸含量高度相关(分别为r = 0.90和0.92)。本研究结果扩展了关于树莓中宝贵生物活性化合物含量变化的知识,并可能有助于最具生产力品种的选择和验证。
