“…Therefore, it can be concluded that these extracts were able to reduce the stable free radical DPPH to the yellow-colored diphenylpicrylhydrazine. Additionally, the IC 50 of this fraction was better than the reported IC 50 values obtained for gallic acid (IC 50 = 64 µg/ml) and BHA (IC 50 = 114 µg/ml) (Ozsoy et al, 2009). The antioxidant activity of the EACS fraction could be attributed to its high total phenolic content.…”

Ceratonia siliqua is a typical plant of the Mediterranean area, which is mainly used as animal and human food and in folk medicine for treating some diseases such as antidiarrheal and diuretic. The present study was planned to evaluate the potential of antimicrobial and antioxidant activities of C. siliqua leaves extract and the identification of bioactive compounds by high performance liquid chromatography/mass spectrometry (HPLC/MS) in the active extract. The antioxidant activities of the different organic extracts of C. siliqua were assayed by 2,2-diphenyl-l-picrylhydrazyl (DPPH) and β-carotene tests. Among the tested extracts, results showed that the ethyl acetate extract displayed the greatest DPPH scavenging ability with an IC 50 of 1.8 µg/ml and a strong β-carotene bleaching inhibition after 120 min of incubation with an IC 50 of 24.01 µg/ml. The investigation of the phenolic and flavonids content showed that the ethyl acetate extract of C. siliqua revealed the highest phenolic contents. Only the ethyl acetate extract of C. siliqua (EACs) showed antimicrobial activity with a broad-spectrum microbiocide with diameter inhibition zones ranging from 12 to 24 mm and MIC values of 0.312 to 1.25 mg/ml. The HPLC finger print of EACs active extract showed the presence of six phenolic compounds. They included (1) 1,6-Di-galloyl-glucose, (2) 1,2,6-Tri-galloyl-glucose, (3) Myricetin glucoside, (4) 1,2,3,6-Tetra-galloyl-glucose, (5) Myricetin rhamnoside and (6) Syringic acid. These results are a good agreement of the popular use and experimentally observed effects of C. siliqua and would promote the reasonable usage and exploitation of the biomolecules of this important plant.

“…Table 3 contains the percentage yield and antioxidant activity of Amarunthus viridis leaf and seed extracts. Graph 2 showed that the maximum extract yields for leaf and seed were obtained with 80% methanol (6.1 g/100 g) and 100% methanol (3.72 g/100 g), respectively [28]. The highest DPPH activity, TP and TF content was found in 100% methanol seed extract and lowest for 100% methanol leaf extracts as shown in Table 3.…”

Methanol extracts of the dried leaves and seeds of Amaranthus viridis were collected and used for phytochemicals and antibacterial analysis. By detecting the MIC and zone inhibition, the antibacterial activity was determined against different bacterial and fungal strains. The extract yields from the leaves and seeds ranged 5.5 -6.1 and 2.42% -3.72% w/w, respectively. Phytochemical investigation of this plant determines that tanins (6.07% -5.96%), saponins (53% -32%), alkaloids (13.14% -11.42%), protiens (16.76% -24.51%) and glycosides (63.2% -32.3%) were rich in leaves. The extracts also contained appreciable levels of total phenolic contents (2.81 -3.61 GAE, g/100 g), total flavanoid contents (18.4 -5.42 QE, g/100 g) and DPPH free radical scavenging activity, showing IC 50 (83.45 -75.95 µg/mL) along with reducing power was calculated. The MIC of extracts ranged 178 -645 µg/mL. The results of this study suggest the possibility of using the methanolic extracts in treating the diseases caused by the test organisms.

Antioxidative compounds play a vital role to inhibit the oxidation of oxidizable products and influences the body defense system against Reactive Oxygen Species (ROS), which are harmful byproducts engendered during normal aerobic cellular respiration. ROS are specialized class of highly reactive molecules that originates during oxygen metabolism, whereas extensive evidences indicate the involvement of ROS in the development of degenerative diseases in humans. Despite the fact that synthetic antioxidants such as butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) are threat to human's health; they are widely employed as chemical preservatives to avert potential deterioration of food products. Several toxicological findings reveal that natural antioxidants are capable of providing protection against free radical-related diseases, cancer and other cardiovascular infections. In cognizance with these facts, natural antioxidant attracts a great deal of research interest; therefore, this review provides a comprehensive and an up-to-date overview of the three most essential natural plant antioxidants; their antioxidative properties, methods of analysis and evaluation. These Polyphenols comprise: Phenolic acid, an essential polyphenol that are broadly dispersed in plants to exert positive influence on oxidative stress; Flavonoid, an ubiquitous antioxidant that functions in free radical scavenging, metal ion chelation and enzymes inhibition to suppress the synthesis of free radicals; and Tannic acid, a water soluble anti-nutrient that acts to precipitate alkaloids & proteins, reduce mineral & vitamin utilization and restrict the activities of digestive enzymes. In conclusion, a variety of plant species were characterized to indicate in vitro antioxidative properties.
