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.
