“…The methanolic extract of W. chinensis reduced the DPPH radical in a dose-dependent manner. Similar trend of results was displayed in the methanolic leaf extracts of several members of Asteraceae family, namely, Helichrysum chionophilum [39], Centaurea cyanus, Centaurea scabiosa [40], Centaurea calolepis, Centaurea cadmea [41], Vernonia amygdalina [42], Diospyros lotus [43], Hieracium pilosella [44], Chrysanthemum balsamita [45], Centaurea cheirolopha, Centaurea kurdica, Centaurea rigida [46], Helichrysum chasmolycicum [47], Hypericum hookerianum [48], and Stevia rebaudiana [49].…”

Objective: The objective is to evaluate the antioxidant activity of the methanolic leaf extract of Wedelia chinensis.Methods: In vitro antioxidant activity was evaluated by studying 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, superoxide radical scavenging activity, ferric reducing ability of plasma (FRAP) scavenging activity, hydroxyl radical scavenging activity, metal chelating activity, and total antioxidant activity. Ascorbic acid, BHT, quercetin, and EDTA were used as standards for the experiments.Results: Inhibition concentration50 values observed for DPPH radical scavenging, superoxide radical scavenging, and hydroxyl radical scavenging activities were determined to be 62.5, 769.23, and 617.28 μg/ml, respectively and that of FRAP scavenging, metal chelating, and total antioxidant activities were found to be 343 μmol Fe (II)/g, 79.56 mg EDTA/g extract, and 398.17 mg ascorbic acid eq/g extract, respectively.Conclusion: The results clearly indicate that methanolic leaf extract of the study species W. chinensis is effective in scavenging free radicals and has the potential to be a powerful antioxidant.

“…The antibacterial activity of flavonoids has been documented in several earlier studies [21, 22]. Flavonoids have multiple cellular targets and may act as nucleic acid synthesis, cytoplasmic membrane function, or energy metabolism inhibitor.…”

“…Also, flavonoids are bacteriostatic compounds which induce the formation of bacterial aggregates thereby reducing the number of viable colonies [23]. The presence of luteolin, which has a hydroxyl group at the 3′ position, was detected, being known as a powerful antimicrobial agent [21]. The proantocyanidin have showed ability to protect the urinary tract infections and antioxidant activity [24].…”

This study evaluated the antimicrobial and hemolytic activities and phytochemical constituents of hydroalcoholic extract and its fractions from Buchenavia tetraphylla leaves. Cyclohexane (BTCF), ethyl acetate (BTEF), and n-butanol-soluble (BTSBF) and non-soluble (BTNBF) fractions were obtained from a liquid-liquid partition of hydroalcoholic extract (BTHE) from B. tetraphylla leaves. The hemolytic activity of active fractions was checked. The BTHE inhibited the growth of Micrococcus luteus (MIC: 0.10 mg/mL), Pseudomonas aeruginosa (MIC: 0.20 mg/mL), Mycobacterium smegmatis (MIC: 0.39 mg/mL), Proteus vulgaris, and Staphylococcus aureus (MIC: 0.78 mg/mL for both). The more active fractions were BTCF and BTBSF. BTCF showed better potential to inhibit M. luteus (0.10 mg/mL), P. aeruginosa (0.20 mg/mL), S. enteritidis (0.39 mg/mL), and S. aureus (1.56 mg/mL). BTBSF showed the best results for M. luteus (0.10 mg/mL), M. smegmatis, B. subtilis (0.39 mg/mL for both), and P. vulgaris (0.10 mg/mL). The HC50 were greater than observed MIC: 20.30, 4.70 and 2.53 mg/mL, respectively, to BTBF, BTHE and BTCF, which. The phytochemical analysis detected the presence of flavanoids, triterpene, carbohydrate, and tannin. Our work showed for the first time the broad-spread antimicrobial activity of B. tetraphylla, which has nonhemolytic action, creating a new perspective on the interesting association of traditional and scientific knowledge.

“…Besides plants, fruits also have been studied by the researchers for the presence of bioactive compounds close related to herbs, commonly referred as phytochemicals such as tannins, carotenoids, polyphenols and anthocyanins (Khushwaha et al, 2012). Crude extracts from plants with a history of use in folk medicines have been screened in vitro for antibacterial activity by many research groups (Suzgec-Selcuk and Birteksoz, 2011).…”
