Abstract
High anthocyanin content and the presence of other bioactive compounds are attractive characteristics of strawberry fruits for healthy consumption. The objective of this study is characterized the anthocyanin content and the presence of other bioactive compounds, including anthocyanin (total and predominant types) and antioxidant activity; and to determine the physico-chemical fruit quality of two new strawberry cultivars. The results found that 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/100g FW with no significant differences between them. Cyanidin 3-glucoside and pelargonidin 3-glucoside were found at amounts of approximately 15-24 mg/kg FW and 332-478 mg/kg FW, respectively. Total phenolic compounds and FRAP activity of the two hybrids were approximately 2295-2579 mg GAE/kg FW and 27-30 mmol Fe2+/kg FW, respectively.
Both of them, 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.
