“…Correlations show that the slope of the three regressions are very close (R 2 = 0.75-0.81) indicating not only that factors affecting scavenging the three radicals and reducing power are similar, but also their contributions have similar weights. High correlations (R 2 > 0.9) were recently reported between any two of DPPH, ABTS and FRAP results (Jiméneza et al, 2015). Besides, Fig.…”

“…Several studies have shown that Baccharis species have anti‐inflammatory and analgesic activity . Moreover, selected Colombian Asteraceae plants used in traditional medicine have exhibited a high antioxidant capacity . Baccharis antioquensis is an endemic plant of Colombia, which can be found in altitudes between 2500 and 3000 m.a.s.l.…”

In the quest for new natural agents of photoprotection, we evaluated the photoprotective and antioxidant activity of B. antioquensis leaf extracts as well as its phenolic composition. The methanolic extract treated with activated carbon showed the highest absorption coefficients for UVA-UVB radiation, as well as an antioxidant capacity comparable to butylated hydroxy toluene. Furthermore, the formulation containing this extract showed suitable sensorial and photostable characteristics for topical use, and significant values of UVAPF, critical wavelength (λc ), UVA/UVB ratio and sun protection factor (5.3, 378 nm, 0.78 and 9.1 ± 0.1, respectively). In addition, three glycoside derivatives of quercetin, a kaempferol glycoside and a derivative of caffeic acid were the main polyphenolic compounds identified. These results demonstrate the potential of B. antioquensis extracts to be used as active components of novel, natural sunscreens.

“…Few reports on vegetable crops indicate that SWE treatment may affect the crop nutritional composition by means of increasing phenolics, flavonoids, and antioxidant capacity [10, 11]. Antioxidant activities are commonly associated with phenolic and flavonoid content in medicinal shrubs [12] and in plants in general [13, 14]. Furthermore, little attention has been given to ornamental medicinal plants [15, 16].…”

Background: Calibrachoa x hybrida (Solanaceae) cultivars are widely used in North and South America as ornamental plants. Their potential as a source of antimicrobial compounds might be enhanced by seaweed extract (SWE) applications. Methods: SWE of Ascophyllum nodosum were applied at 5 and 7 ml/L as a soil drench or foliar spray on Calibrachoa cultivars of Superbells® 'Dreamsicle' (CHSD) and Superbells® 'Frost Fireʼ (CHSF). The total phenolics, tannins and antioxidants composition as well as specific flavonols in leaf extracts were determined. Further, the chemical composition of SWE was assessed. Results: The drench and foliar SWE treatments significantly enhanced Calibrachoa cultivars leaf number and area, dry weight, plant height, antioxidant capacity as well as phenolic, flavonols and tannin content. The increased growth and composition of phenols, flavonols and tannins was attributed to the stimulatory effects of SWE mineral composition. The antifungal activity of Calibrachoa cultivars was significantly enhanced following SWE treatments and the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) were in the range of 0.07-0.31 mg/ml and from 0.16 to 0.56 mg/ml, respectively. Moreover, antibacterial activity was significantly increased and the MIC and minimum bactericidal concentration (MBC) measurements were in the range of 0.06-0. 23 mg/ml and from 0.10 to 0.44 mg/ml, respectively. The most sensitive fungus to SWE treatments was C. albicans and the most sensitive bacterium was E. cloacae. Conclusion:The results suggest that enhanced antifungal and antibacterial activities might be attributed to significant increases of phenolic, flavonols and tannin contents, which ultimately enhance the potential of Calibrachoa as a natural source of alternative antibiotics.
