BACKGROUND:High anthocyanin content and the presence of other bioactive compounds are attractive characteristics of strawberry fruits for healthy consumption. OBJECTIVES:To characterize the anthocyanin content and the presence of other bioactive compounds, including anthocyanin (total and predominant types) andantioxidant activity; and to determine the physico-chemical fruit quality parameters of two new strawberry cultivars. METHOD:Fruits of two new hybrids were extracted and total anthocyanin and antioxidant activity were determined usinga UV-Vis spectrophotometer. Individual anthocyanins and vitamin C were measured using an HPLC. Physico-chemical characteristics of fruits were analyzed. RESULTS:Hybrid No. 4 line 5 and hybrid No. 4 line 26 are two potential new strawberry cultivars that are rich in anthocyanins. The total anthocyanin contents of these two hybrids were approximately 31–38 mg/100 g FW with no significant differences between them. Cyanidin 3-glucoside and pelargonidin 3-glucoside were foundat amounts of approximately 15–24 mg/kgFW and 332–478 mg/kg FW, respectively. Total phenolic compounds and FRAP activity of the two hybrids were approximately 2295–2579 mg GAE/kgFWand 27–30 mmol Fe2 +/kg FW, respectively. CONCLUSION:The two new hybrid strawberry lines, hybrid No. 4 line 5 and No. 4 line 26, when compared to the parents, had higher levels of bioactive compounds, especially anthocyanins, total phenolics, and FRAP, together with improved physico-chemical quality, and higher vitamin C content. These results indicate a considerable potential of these hybrids for commercial cultivation in Thailand and other production regions.

潜在的富含花色素苷的草莓新品种花色苷含量，生物活性化合物和理化特性

背景：花青素含量高和其他生物活性化合物的存在是草莓果实健康食用的诱人特征。目的：表征花色苷含量和其他生物活性化合物的存在，包括花色苷（全部和主要类型）和抗氧化活性；并确定两个草莓新品种的理化果实品质参数。方法：提取两个新杂种的果实，并用紫外可见分光光度计测定总花色苷和抗氧化活性。使用HPLC测量各个花色苷和维生素C。分析了水果的理化特性。结果：杂交4号5号和杂种4号26号是两个潜在的新草莓品种，富含花青素。这两个杂种的总花色苷含量约为31–38 mg / 100 g FW，两者之间无显着差异。氰胺3-葡萄糖苷和pelargonidin 3-葡萄糖苷的含量分别约为15-24 mg / kgFW和332-478 mg / kg FW。两个杂种的总酚类化合物和FRAP活性分别约为2295-2579 mg GAE / kgFW和27-30 mmol Fe2 + / kg FW。结论：与亲本相比，两个新的杂交草莓品系，第4代5号和第4代26号具有较高的生物活性化合物，尤其是花色苷，总酚和FRAP，并且理化特性得到改善质量和较高的维生素C含量。这些结果表明这些杂种在泰国和其他产区的商业化种植中具有很大的潜力。
