Recently, there has been increasing interest in medicinal plants, due to their content of health-promoting compounds, e.g., caffeic acids derivatives. Hence, the aim of this work was to study the antioxidant activity of extracts obtained from the following medicinal plants: caraway (Carum carvi L.), coltsfoot (Tussilago farfara L.), dandelion (Taraxacum officinale F.H.Wigg.), lovage (Levisticum officinale L.), tarragon (Artemisia dracunculus L.) and white mulberry (Morus alba L.), characterized by their high content of caffeic acid derivatives. The water-ethanolic extracts were characterized on average by about 9 times higher contents of caffeic acid derivatives level than water extracts. Both in water and water-ethanolic extracts, the dominant phenolic acid was 5-CQA (5-O-caffeoylquinic acid) and 3,4-diCQA (3,4-dicaffeoylquinic acid), then CCA-1 (chicoric acid isomer 1), which appeared only in water-ethanolic extracts. Extracts from dandelion contained compounds such as CTA (caftaric acid), CCA-1 (chicoric acid isomer 1) and CCA-2 (chicoric acid isomer 2), which were not detected in other plant extracts examined in this work. The water-ethanolic extracts from coltsfoot and tarragon were characterized by a high content of di-caffeoylquinic acids, especially 3,4-diCQA and 3,5-diCQA, respectively. It has been stated that there is a positive correlation between caffeic acid derivatives and antioxidant activity (radical cation scavenging activity (ABTS) and radical scavenging activity (DPPH)), especially in water-ethanolic extract of medicinal plants.

Research of radical scavenging activity of sambiloto (Andrographis paniculata Nees) and patikan kebo (Euphorbia hirta L) ethanolic extracts and their combination toward 2,2-Diphenyl-1-Picrylhidrazyl (DPPH) has conducted. Subjects of this experiment comprise sambiloto ethanolic extract, patikan kebo ethanolic extract, dechlorophyllated extract of sambiloto and combinations among those three. Dechlorophyllation by electrocoagulation method is done to reduce chlorophyll content thereby increasing the level of active compound in the sambiloto extract. The results of dechlorophyllation showed that only total flavonoid content in the extract of sambiloto increased, meanwhile the radical scavenging activity results showed that patikan kebo ethanolic extract has the lowest IC50 value (22,36 µg/mL) compared to sambiloto ethanolic extract (IC50 value 499,03 µg/mL). Extract combination may increase DPPH radical scavenging activity of the sambiloto extract (IC50 value 76,06 µg/mL) but not higher than that of patikan kebo single extract.

Summary While there is a large number of scientific papers reporting chemical composition and biological activities of Aronia melanocarpa, there is a lack information regarding the commercially available bagged tea. In order to supply new information on the antioxidant activity of the Aronia melanocarpa tea infusions, the aim of this study was to evaluate individual phenolic compounds which could be responsible for antioxidant activities of these beverages. Selected anthocyanins (cyanidin-3-O-galactoside, cyanidin-3-O-glucoside, cyanidin- 3-O-arabinoside, and cyanidin-3-O-xyloside), gallic acid, caffeic acid, rutin, morin, and protocatechuic acid were simultaneously detected from commercially available tea infusions using a High Performance Liquid Chromatographic (HPLC) method. The antioxidant activity was measured using five in vitro spectrophotometric methods: 1,1-diphenyl- 2-picrylhydrazyl radical scavenging activity (DPPH), 2,2'-azino-bis (3-ethylbenzthiazoline- 6-sulphonic acid) radical cation scavenging activity (ABTS), ferric reducing-antioxidant power (FRAP) and reduction power (RP)Fe(III) to Fe(II). Obtained results showed that anthocyanins, predominantly of cyanidin-3-O-galactoside, are the major class of polyphenolic compounds in tea infusions. Among phenolic acids the most abundant is caffeic acid. A significant correlation between DPPH and ABTS and FRAP and RP suggested that antioxidant components in these beverages were capable scavenging free radicals and reducing oxidants. Generally, these beverages had relatively high antioxidant capacities and could be important dietary sources of antioxidant phenolics for the prevention of diseases caused by oxidative stress.

The antioxidant activity of extracts of Acacia confusa of different ages has been evaluated. Ethanolic extracts of bark, twigs, branches (2- and 5 cm-diameter branch-bark, 2- and 5 cm-diameter branch-wood), and leaves of 15-, 25-, and 35-year-old A. confusa were examined. Results indicate that the ethanolic extracts of 5 cm-diameter branch-bark and bark of A. confusa exhibited stronger antioxidant activities, and higher phenolic and proanthocyanidin contents than the other plant parts. Furthermore, twig, 2 cm-diameter branch-wood, 2 cm-diameter branch-bark, and 5 cm-diameter branch-wood extracts of 35-year-old specimens showed better antioxidant activities and higher phenolic contents, followed by the 25- and 15-year-old specimens tested. This reveals that the composition of extracts and their differential antioxidant activities are dependent on the age of A. confusa. In addition, the total phenolic content of A. confusa ethanolic extracts has a high positive correlation with the DPPH free-radical scavenging activity (R2 = 0.83), superoxide radical-scavenging activity (R2 = 0.66), ferrous ion-chelating effect (R2 = 0.67), and reducing power (R2 = 0.92).
