In order to promote medicinal plants in Algeria, the present work aimed to assess the physico-chemical characterization, hemolytic, and antioxidant activities of Ammodaucus leucotrichus essential oil of an endemic plant from south-west of Algeria. The plant was harvested from the region of Bechar (south-west of Algeria). The oil was obtained by hydrodistillation method using Clevenger apparatus. The antioxidant activity of the oil was carried out using DPPH scavenging assay, and its effect on erythrocyte cells was evaluated by measuring the hemolytic degree. The obtained results showed that this oil presented a low antioxidant activity compared to positive control (ascorbic acid). The hemolytic activity was very low since the oil diluted to 1/10, while it was low in the pure state. This fact proves the safety of A. leucotrichus oil, which can explain its use without risk by the indigenous population. \u0000REFERENCES: \u0000Abu Zarga, M.H., Al-Jaber, H.I., Baba Amer, Z.Y., Sakhrib, L., Al-Qudah, M.A., Alhumaidi, J.Y.G., Abaza, I.F., & Afifi, FU.

Extract and fractions prepared by maceration from S. officinalis were determined for their phytochemical composition and their contents in total phenolic and flavonoid. Antioxidant activity was evaluated by the methods of DPPH radical scavenging, ferric reducing antioxidant power and total antioxidant capacity. Hemolysis assay was carried out to evaluate the toxicity of the studied samples. Crude extract and fractions from S. officinalis contain different secondary metabolites and considerable contents of phenolic and flavonoids. They exhibit high antioxidant activity and low hemolytic effect. However, ethyl acetate fraction is characterized by the highest total phenolic (362.75 ± 0.07 µg GAE/mg DE) and flavonoid (263.27 ± 0.1 µg CE/mg DE) contents. Furthermore, this fraction shows the best antioxidant activity tested by DPPH, FRAP and TAC assays. The antiradical activity of ethyl acetate fraction against DPPH (IC50 = 208.51 ± 5.77 μg/mL) is close to that of ascorbic acid (IC50 = 206.43 ± 4.16 μg/mL). It exhibits a powerful activity to reduce iron (EC50 = 250 ± 0.001 μg/mL) and the best total antioxidant capacity (817.33 ± 0.06 μg/mL). It reveals the lowest hemolysis rate of 3.77 ± 0.02% with 200 mg/mL of fraction, after one hour of incubation. The obtained results suggest that crude extract, ethyl acetate and n-butanol fractions from Salvia officinalis L. are considered efficient natural antioxidants and safe for human erythrocytes. \u0000REFERENCES: \u0000Andrei, M., Cadmiel, M., Simone, C., Marcello, L., Marina, S., & Gianina, C.

Sixty two components were identified and the results indicated that the essential oil was rich in hydrocarbons monoterpenes and phenylpropanoid compounds. 6-Methoxyelemicine (0.1- 47.0%), sabinene (1.4-35.5%), limonene (0.6-24.0%), myristicine (0.2-18.9%), α-pinene (3.1- 14.7%) and dill apiole (0.0-10.6%) were the major compounds.

The tested oils have been shown to possess inhibitory action in the range from 2 to 3 µL/mL against Aspergillus fumigatus, Staphylococcus aureus and Candida albicans. The antimicrobial activity of essential oil from P. Scoparius well be due probably to the presence of synergy between myristicine and terpinen-4-ol.

This review is devoted to health benefits of the carob leaf which are attributed in particular to its phytochemical constituents such as quercetin and gallic, coumaric, chlorogenic acids. Extracts from carob leaves (CLs) have been investigated for their biological activities including anti-cholestinerase, anti-inflammatory, Antidiarrhoeal, anti-tumor, anti-cancer, antimicrobial, hepatoprotective, nephroprotective, antidiabetic and antiobesity as well as phytochemical profile and nutritive value of the CLs. Hence, extracts from Ceratonia siliqua L. leaves, a huge source of bioactive compounds, exhibit a panoply of biological properties.
