The worldwide tendency for growing more small fruits, including raspberries, shows permanent increase because this group of fruits has a relatively higher content of bioactive nutrients. To study the health benefits of red raspberry fruits, 11 preselected wild-grown and 1 well-known cultivar, Heritage, were evaluated for some of their physicochemical properties such as fruit weight, total antioxidant capacity (measured by beta-carotene bleaching and FRAP assays), total phenolics, ascorbic acid, soluble solid content (SSC), and acidity. Fruit weight, SSC, and ascorbic acid contents were between 1.47 and 2.32 g, 10.87% and 13.60%, and 21 and 36 mg/100 g, respectively. Antioxidant activity and total phenolic content varied among genotypes and the ERZ5 genotype had the highest antioxidant capacity as ascertained by both methods. This genotype also had the highest total phenolic (2031 microg GAE/g FW) content. There are linear relationships between antioxidant capacities and total phenols. The present study demonstrates the potential of certain wild genotypes, notably ERZ5, for improving the nutritional value through germplasm enhancement programs.
全世界范围内小浆果（包括覆盆子）的种植量不断增加，因为这类水果含有相对较高的生物活性营养物质。为了研究红树莓的健康益处，对 11 种预选的野生品种和 1 种知名品种 Heritage 的一些理化特性进行了评估，包括果实重量、总抗氧化能力（通过β-胡萝卜素漂白和 FRAP 测定法测定）、总酚类、抗坏血酸、可溶性固形物含量（SSC）和酸度。果实重量、SSC 和抗坏血酸含量分别在 1.47 到 2.32 克、10.87%到 13.60%和 21 到 36 毫克/100 克之间。抗氧化活性和总酚含量因基因型而异，ERZ5 基因型通过两种方法确定具有最高的抗氧化能力。该基因型的总酚含量也最高（2031 微克 GAE/g FW）。抗氧化能力和总酚含量之间存在线性关系。本研究表明，某些野生基因型（尤其是 ERZ5）具有通过种质改良计划提高营养价值的潜力。
