Reactive oxygen (ROS) and nitrogen species (RNS) are produced in all cells and play important roles in physiology. The loss of the redox balance, either by an increase of oxidant molecules ROS and RNS or by decreased antioxidant system activities cause a state of oxidative stress. Several studies are going on worldwide directed towards finding natural antioxidants of plant origin. Plants containing phenolic compounds have been reported to possess strong antioxidant activity. The objective of this study is to evaluate total polyphenols and flavonoids contents (TPC and TFC) as well as examine the in vitro antioxidative properties from aqueous extract of Ammoides atlantica (AqE). TPC was estimated utilizing Folin-Ciocalteu's reagent. TFC was evaluated utilizing the aluminum chloride method. The antioxidant properties were evaluated using metal chelating and cupric ion reducing antioxidant capacity (CUPRAC) assays. Indeed, results showed that the AqE is rich in polyphenols (141.74±0.44 µg gallic acid equivalents/ mg of dry weight), and flavonoids (61.87±6.7 µg quercetin equivalent/ mg dry weight). These phytochemical compounds possess significant antioxidant activities. The results showed that AqE exhibited a good Metal chelating activity with an IC50 of 36.57±4.73 µg/ mL. CUPRAC assay showed that AqE extract exhibited high cupric ion reducing antioxidant capacity with an A0.5 of 8.58±0.13 µg/mL. These findings provide evidence that AqE of Ammoides atlantica is a potential source of antioxidant which have many benefits towards human health. Keywords: Ammoides atlantica, aqueous extract, phenolic compounds, metal chelating and cupric ion reducing antioxidant capacity.

“…The strong activity of the plant extract to scavenge the radical DPPH could be attributed to its richness in tannins (301.4 ± 0.0009 mg TAE/g DW) and phenolics acids (164.20 ± 0.003 mg GAE/g Dw). Thus, secondary metabolites present in the plant extract can neutralize DPPH-free radicals; by provide hydrogen atoms or donate electrons and convert them to a colorless/bleached substance (2,2-diphenyl-1 hydrazine or equivalent hydrazine substituted), resulting in a decrease in absorption at the 517 nm level 23 .…”

The plants of the genus Phlomis are native to Turkey, North Africa, Europe and Asia. Phlomis bovei De Noé (Lamiaceae) is a rare Algerian endemic plant, commonly known as Kayat El Adjarah. The objective of this study is to quantify the polyphenol content and to evaluate the antioxidant activities of the ethanolic extract (EthE) of Phlomis bovei De Noé. The plant extract was prepared by macerating 100 g of ground material in 1000 ml of 85 % ethanol for 72 h, then the filtrate was evaporated using a rotary evaporator at a temperature of 45C and the filtrate was dried. The total content in polyphenols was determined using Folin Ciocalteu method. Flavonoid content in extracts was determined using Aluminum trichloride assay and the total content of tannins was determined according to Bate Smith method. The antioxidant activity was investigated in vitro by the DPPH (2, 2-diphenyl-1-picryl-hydrazyl), ABTS and iron chelating assays. The results indicate that the ethanol extract was rich in polyphenols and has an important capacity of scavenging the DPPH and ABTS free radical with an IC50 of 0.05 and 0.018 mg/ml, respectively. However, in the ferrous ions chelating ability test, PBEE extract showed moderate chelating activity (IC50 = 1.59 ± 0.05 mg/ml). To conclude, the obtained results may contribute to add possible scientific data to use Phlomis bovei industrially as herbal medicine and as supplementary sources for natural antioxidant drugs in food. Keywords: antioxidant activity, ethanol extract, Phlomis bovei De Noé, polyphenol content.

Flaxseed and fennel seeds are rich sources of different types of phenolics such as lignans, phenolic acids, flavonoids, phenylpropanoids, and tannins. The present study was carried out to develop and optimize a technique for isolation and quantification of secoisolariciresinol diglucoside (SDG) from flaxseed and Anethole from fennel seeds and to assess the antioxidant activities of flaxseed (Linum usitatisimum L.) and fennel seeds (Foeniculum vulgare Mill.) extracts. The percentage of extract in fennel seeds and flaxseed was 5.72 and 6.31 %, respectively. Using HPLC, the predominant constituent in fennel seed was determined to be anethole (11.30±0.25 mg/g) and in flaxseed, it was secoisolariciresinol diglucoside (SDG) (8.35±0.52 mg/g) compared to the respective standards solution. Using SPSS, the obtained data from each parameter were statistically analyzed. There are numerous biological and pharmacological effects of trans-anethole. For antioxidant activity, 2,2′-azinobis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) showed higher results with acetone (80%), with fennel seed and flaxseed is 7.28±0.17 and 8.29±0.23 mM TE/g. while FTC method it was maximum for distilled water extract of fennel seed (48.35±0.19%) and Flaxseed (65.09±0.72%) and by β-carotene Defatted Flaxseed Powder and Defatted Fennel Seed Powder PreparationThe seed samples were ground into a fine powder using a commercial blender (TSK-949, WestPoint, France). The material that passed through 80-mesh sieve bleaching method, water extract of fennel seed and flaxseed also showed maximum antioxidant activity i.e. 83.06±0.02% and 86.23±0.38%. Additionally, it is used as a masking agent in food products as a flavoring agent. According to the findings of this study, fennel seeds and flaxseed contain bioactive compounds that may assist in the treatment of a number of chronic diseases.
