Aim: This study was designed to investigate the phytochemical profile and the cytotoxic activities of the eco-friendly extracts of olive leaves from Chemlali cultivar. Materials and Methods: The Phenolic composition of olive leaves extracts, the antioxidant activity and the cytotoxic effects against MCF-7 and HepG2 cells were determined. Results: Olive leaves extracts showed relevant total polyphenols contents. Oleuropein was the major detected phenolic compound reaching a concentration of 16.9 mg/ml. The antioxidant potential of the studied extracts varied from 23.7 to 46.5mM Trolox equivalents as revealed by DPPH and ABTS assays. Cytotoxicity experiments showed similar trends for both HepG2 and MCF-7 cells with the infusion extract being the most active. Conclusion: This study denotes that olive leaves may have great potential as endless bioresource of valuable bioactive compounds which may have a wide application.

Phytochemical Profile

Background: One of the four most incident species in mangrove is the Laguncularia racemosa, plant widely used in popular medicine against inflammation and fever. Objective: Here, L. racemosa was investigated in relation to their phytochemical profile, antioxidant activity, citotoxicity, antimicrobial and immunostimulatory effect. Method: Aqueous extract was obtained from leaves of plant, its phytochemical profile was investigated through UPLC method, the antioxidant assays performed were TAA, DPPH, ABTS, nitrite and lipid peroxidation assay. Antimicrobial assays were made using standard strains. For all biological tests were used mice splenocytes and from these cell cultures were measured cytotoxicity, proliferation index and cytokines production. Results: Laguncularia racemosa leaves showed the presence of ions, proteins, carbohydrates, vitamins and high concentration of phenolic compounds. Antioxidant activities were promoted by aqueous extract, especially in DPPH and NO assays. Extract in 6 µg/mL did not induce significant cell death, stimulated the cell proliferation and the IL-4 production. Moreover, decreases of proinflammatory cytokines IFN-γ, TNF-α and IL-6 were found. Conclusion: The presence of essential nutrients, significant antioxidant activity and immune stimulation confirm the use of this plant in folk medicine against inflammation.

Abstract Background Essential oils are chemical products produced by odoriferous glands from a variety of plants. These essential oil have many health benefits i.e. antiseptic, anti-inflammatory and antimicrobial activities. So due to these medicinal properties present study was designed to analyze essential oil of Thymus vulgaris and Mentha arvensis for their chemical composition and biological activities. Materials and methods Essential oil from these plants were extracted by hydrodistillation method, and analyzed by GC-MS. To test the microbial activity of these oil disk diffusion method and micro wells method were used. For free radical scavenging DPPH assay was used. However total phenolic content was measured by colorimetric method. Results The GC-MS analysis of T. vulgaris oil showed the presence of 47 chemical compounds among which thymol, terpinene, p-cymene and carvacrol were major. However essential oil of M. arvensis showed the presence of 28 constituents, among which the Menthone, Menthol, Isomenthone, Eucalyptol, neo-Menthol, cis-Piperitone oxide, Linalool, Thymol, Limonene, and α-Phellandrene were major. Essential oil from both these plant tested for antimicrobial activity showed that the T. vulgaris oil was effective against seven bacterial strains and the essential oil of M. arvensis was effective against six bacterial strain. The antioxidant activity of both samples by DPPH assay which showed positive result. Conclusion As both species showed the presence of active components, positive microbial activities, and antioxidant activity so, research should be carried on for further biological activities of these oil for betterment of living beings.
