Objective: Anthocyanins are the water-soluble pigments most commonly present in flowers, fruits, and vegetables. Anthocyanins have been reported for is antioxidant, anti-inflammatory, antibacterial properties and other health benefits in human. This study was performed to extract and determine the anthocyanin and to access the antioxidant properties of the most commonly used fruits, vegetables and flowers in Thailand.Methods: Extraction of anthocyanin and its aglycones from the selected samples and determination of anthocyanin and anthocyanidins using reversed-phase HPLC analysis. Determination of total antioxidant ability using ABTS, DPPH and FRAP assay.Results: Maximum distribution of tested anthocyanin and anthocyanidin contents was observed in the extracts of Jambolan plum, Ceylon Spinach, Purple Sweet Potato, Purple Lettuce followed by common plum and Red dragon fruit. The extracts of Ma-Kiang, Purple Eggplant, Red Grape, and Purple Lettuce showed the maximum amount of cyanidin 3-glucoside, delphinidin 3-glucoside, peonidin 3-glucoside, and malvidin 3-glucoside, respectively. Likewise, the maximum concentration of cyanidin, delphinidin, peonidin, and malvidin were found in Common plum, Red Khae, Red Cabbage, and Purple Lettuce, respectively. Ma-Kiang extract exhibited the maximum antioxidant activity followed by Red Cabbage, Common Plum, and Purple Eggplant extract compared to the other extracts.Conclusion: The present study, primarily profiled the anthocyanin content of selected fruits, vegetables, and flowers. Among the tested samples, Ma-Kiang extract showed the high cyanidin 3-glucoside content and antioxidant activity. Further, detailed study on the content of anthocyanins at different climate and geographical conditions and other factors are necessary to develop nutraceutical or cosmetic product with a functional ingredient.Keywords: Anthocyanin, Anthocyanidin, Antioxidant activity.

“…Lettuce (Lactuca sativa L.), a horticultural crop of economic importance, is one of the Asteraceae family's most extensively cultivated and eaten fresh vegetables. (Rubatzky and Yamaguchi, 1997). Its global production reached more than 29 million tonnes in 2019, with about one million produced in Spain.…”

Horticultural crops constantly face abiotic stress factors such as salinity, which have intensified in recent years due to accelerated climate change, significantly affecting their yields and profitability. Under these conditions, it has become necessary to implement effective and sustainable solutions to guarantee agricultural productivity and food security. The influence of BALOX®, a biostimulant of plant origin, was tested on the responses to salinity of Lactuca sativa L. var. longifolia plants exposed to salt concentrations up to 150 mM NaCl, evaluating different biometric and biochemical properties after 25 days of treatment. Control plants were cultivated under the same conditions but without the biostimulant treatment. An in situ analysis of root characteristics using a non-destructive, real-time method was also performed. The salt stress treatments inhibited plant growth, reduced chlorophyll and carotenoid contents, and increased the concentrations of Na+ and Cl- in roots and leaves while reducing those of Ca2+. BALOX® application had a positive effect because it stimulated plant growth and the level of Ca2+ and photosynthetic pigments. In addition, it reduced the content of Na+ and Cl- in the presence and the absence of salt. The biostimulant also reduced the salt-induced accumulation of stress biomarkers, such as proline, malondialdehyde (MDA), and hydrogen peroxide (H2O2). Therefore, BALOX® appears to significantly reduce osmotic, ionic and oxidative stress levels in salt-treated plants. Furthermore, the analysis of the salt treatments’ and the biostimulant’s direct effects on roots indicated that BALOX®’s primary mechanism of action probably involves improving plant nutrition, even under severe salt stress conditions, by protecting and stimulating the root absorption zone.
