Introduction: In this research, we have reported the chemical composition and bioactivity of the essential oil from flowers of Matricaria chamomilla var. Chamomilla (MCCO) for the first time. The essential oil was extracted using a Clevenger-type apparatus. The chemical composition of the essential oil was identified by chromatography methods. DPPH Radical Scavenging Activity (RSA), β-carotene bleaching (BCB), and Ferrous Ion Chelating ability (FIC) were chosen to evaluate the MCCO antioxidant activity. Disc diffusion assay and Mínimum Inhibitory Concentration method (MIC) were selected to investigate antibacterial activity of MCCO. Hemolytic activity of MCCO on Red Blood Cells (RBCs) was measured through optical density. Methods: MTT method was used to determine the cytotoxicity effects of MCCO on human cáncer cells. MCCO was dominated byoxygenated sesquiterpenes (59.01%). α-Bisabolone oxide A (35.74%), α- bisabolol oxide A (19.07%), (Z)-β-farnesene (6.63%), and chamazulene (6.46%)wasfound as themajorcomponents oftheessentialoil. The oil represented an acceptable antioxidant activity. For antibacterial activity, MCCO prevented the growth of all selected microorganisms. The oil can be considered as a strong antibacterial agent as well as anantioxidant. Results: MCCO showed a low hemolytic rate (below 1.5%) on RBCs. The safety of MCCO as a food additive or other uses was suggested by the hemolysis result. Conclusions: MCCO was identified as a weak agent in the cytotoxicity assay.

Background: The essential oil from the Acantholimon genus have been an integral part of the traditional food additive in Middle East. Most of the plants in Acantholimon genus have not been studied scientifically. The aim of this study is to investigate the chemical composition, antibacterial, insecticidal and anti-oxidant activities of three Acantholimon species including Acantholimon atropatanum, A. gilliatii and A. tragacanthium. Method: The essential oils of the aerial parts were extracted by hydrodistillation. Chemical constitutions were identified by gas chromatography- mass spectroscopy technique, also their toxicities were assessed against the two important grain products pests, Oryzeaphilus mercator and Tribolium castaneum. Antibacterial activity was assessed against the three foodborne bacteria that include Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus based on the disc diffusion assay. Free-radical-scavenging property was identified based on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. Results: 2-hexahydrofarnesyl acetone was the main compound in A. gilliatii and A. tragacanthium, whilst farnesyl acetone, heptacosane and germacrene D were the principal components of A. atropatanum essential oil. These oils exhibited 40-90% mortality of O. mercator and/or T. castaneum at a dose of 12 μl/l air after 48h of exposure, and exhibited significant free-radicalscavenging property (RC50 = 3.7 × 10-3 - 8.3 × 10-3 mg/ml). The oils of A. tragacanthium and A. gilliatii showed a weaker antibacterial activity compared to A. atropatanum. Conclusion: A. atropatanum, A. gilliatii and A. tragacanthium essential oils had significant insecticidal and anti-oxidant properties. They also showed week to moderate antibacterial activity against P. aeruginosa and S. aureus.

Background: Rhus pentaphylla Desf. (Anacardiaceae) widely grown in Algeria, is an underutilized plant and remains poorly studied. To investigate for the first time, the chemical composition profile of essential oil and hydrosol extract; besides Total Phenolic (TPC), Flavonoid (TFC) and Condensed Tannins Contents (CTC) of fruits, leaves and roots, the fatty acid composition was assessed. The radical scavenging activity of R. pentaphylla extracts was then evaluated. Methods: Essential oil and hydrosol extract were isolated respectively by hydrodistillation and liquidliquid- extraction from the aerial parts of R. pentaphylla. The antioxidant activity was evaluated using 2,2-Diphenyl-1-Picrylhydrazyl (DPPH) radical and ferric reducing antioxidant power (FRAP). Chemical compositions of various extracts were investigated using Gas Chromatography (GC) and GC-Mass Spectrometry (GC-MS). Results: The results of GC and GC-MS analysis revealed 83 components in essential oil and 75 components in hydrosol extract representing respectively 96.9% and 92.5% of the total extract composition. The main constituents were hexadecanoic acid (31.5%) followed by spathulenol (14.9%) in the oil while the higher amount present in the hydrosol extract was of spathulenol (14.2%). Otherwise, 13 and 18 fatty acids were identified in roots and fruits respectively. The highest levels of TPC and CTC were found in roots extracts while the highest quantity of TFC has been recorded in the leaves extract. Besides, hydrosol extract was able to scavenge DPPH and FRAP free radicals more efficiently than essential oil. Conclusion: R. pentaphylla contains bioactive substances that could be used as a new promising source of antioxidant compounds in different applications.

Aims: To study the chemical composition of volatile oil samples from different place in Egypt (Mansoura, Gamsa and Assuit) and study their antioxidant activity determined by DPPH assay. Study Design: Hydro distillation of volatile oil samples and their GC/MS analysis and determination of their antioxidant activity by DPPH assay. Place and Duration of Study: Department of Pharmacognosy, Faculty of pharmacy, Mansoura university, Egypt, between June 2015 and November 2017.   Methodology: The essential oil was isolated by hydro-distillation for 5 h using a Clevenger-type all-glass apparatus according to the standard procedure of the European pharmacopeia and volatile oils analysis was performed by GC and GC-MS. GC analysis was carried out using Focus-DSQ-ӀI GC/MS instrument (Thermo Scientific, MA, USA) equipped with TR-5 fused silica column (30 m × 0.25 mm, film thickness 0.25 µm). Results: The yield of the essential oils of three rosemary plants growing in Mansoura (RM), Gamsa (RG) and Assiut (RA) were 0.20% v/w, 0.32% v/w and 0.24% v/w, respectively. Their chemical composition was analyzed by GC/MS, RM and RG were found to be α-pinene dominated chemotypes, 32.4% and 29.6%, respectively, meanwhile RA was camphor dominated chemotype (17.2%). Furthermore, their antioxidant activity was determined by DPPH assay. Their IC50 values of essential oils of RM, RG and RA were 8.66 ± 0.7, 8.18 ± 0.5 and 9.74 ± 0.2, respectively. Conclusion: The GC/MS spectral data revealed the considerable difference between the chemical composition of essential oil constituents of RM, RG and RA which lead to different chemotypes. The present results also demonstrate that REO obtained from different areas in Egypt exhibited free radical scavenging activity determined by DPPH assay due to the synergistic effect between their constituents.

The investigation aimed to study the in vitro and in silico antioxidant properties of Melissa officinalis subsp. officinalis essential oil (MOEO). The chemical composition of MOEO was determined using GC–MS analysis. Among 36 compounds identified in MOEO, the main were beta-cubebene (27.66%), beta-caryophyllene (27.41%), alpha-cadinene (4.72%), caryophyllene oxide (4.09%), and alpha-cadinol (4.07%), respectively. In vitro antioxidant properties of MOEO have been studied in 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free-radical scavenging, and inhibition of β-carotene bleaching assays. The half-maximal inhibitory concentration (IC50) for the radical scavenging abilities of ABTS and DPPH were 1.225 ± 0.011 μg/mL and 14.015 ± 0.027 μg/mL, respectively, demonstrating good antioxidant activity. Moreover, MOEO exhibited a strong inhibitory effect (94.031 ± 0.082%) in the β-carotene bleaching assay by neutralizing hydroperoxides, responsible for the oxidation of highly unsaturated β-carotene. Furthermore, molecular docking showed that the MOEO components could exert an in vitro antioxidant activity through xanthine oxidoreductase inhibition. The most active structures are minor MOEO components (approximately 6%), among which the highest affinity for the target protein belongs to carvacrol.

This study compares the content of basic nutrients (proteins, fats, digestible carbohydrates, dietary fiber and ash), steviol glycosides, selected antioxidants (vitamin C, total polyphenols) and antioxidant activity in dried leaves of Stevia rebaudiana Bertoni cultivated in Poland, Paraguay and Brazil and available in the direct sale. The basic chemical composition was determined by standard AOAC (Association of Official Analytical Chemists) methods. Content of steviol glycosides was determined by the UHPLC-UV chromatographic method. Total polyphenols content was expressed as gallic acid equivalent (GAE) and catechins equivalent (CE). Antioxidant activity was measured as ABTS●+ free radical scavenging activity. Dried leaves of S. rebaudiana grown in Poland had significantly higher contents of dietary fiber, and lower protein and ash content, compared to those derived from Paraguay and Brazil. The former had, however, considerably higher contents of total steviol glycosides, stevioside and rebaudioside D, compared to the remaining two plants. In the Paraguay-derived dried leaves, the content of rebaudioside A, C, E and rubusoside was found to be significantly lower. Dried leaves of S. rebaudiana Bertoni, cultivated in Poland, contained substantially more vitamin C and a similar content of total polyphenols, compared to those from Brazil and Paraguay. The examined material from Brazil and Paraguay plantations showed similar antioxidant activity, while that obtained from Polish cultivation was characterized by a significantly lower value of this parameter.

Essential oils (EOs) from Citrus are the main by-product of Citrus-processing industries. In addition to food/beverage and cosmetic applications, citrus EOs could also potentially be used as an alternative to antibiotics in food-producing animals. A commercial citrus EO—Brazilian Orange Terpenes (BOT)—was fractionated by vacuum fractional distillation to separate BOT into various fractions: F1, F2, F3, and F4. Next, the chemical composition and biological activities of BOT and its fractions were characterized. Results showed the three first fractions had a high relative amount of limonene (≥10.86), even higher than the whole BOT. Conversely, F4 presented a larger relative amount of BOT’s minor compounds (carvone, cis-carveol, trans-carveol, cis-p-Mentha-2,8-dien-1-ol, and trans-p-Mentha-2,8-dien-1-ol) and a very low relative amount of limonene (0.08–0.13). Antibacterial activity results showed F4 was the only fraction exhibiting this activity, which was selective and higher activity on a pathogenic bacterium (E. coli) than on a beneficial bacterium (Lactobacillus sp.). However, F4 activity was lower than BOT. Similarly, F4 displayed the highest antioxidant activity among fractions (equivalent to BOT). These results indicated that probably those minor compounds that detected in F4 would be more involved in conferring the biological activities for this fraction and consequently for the whole BOT, instead of the major compound, limonene, playing this role exclusively.

ABSTRACT: In the present study, antibacterial and antioxidant [1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity] activities of a weed, slender amaranth (Amaranthus viridis L.) were investigated. Extracts of different plant parts were prepared in n-hexane, chloroform and ethyl acetate. Antibacterial activity was measured by using 100 mg mL-1 concentration extracts against 4 deadly phytopathogenic bacterial species viz. Pseudomonas syringae Van Hall, Ralstonia solanacearum Smith, Erwinia carotovora (Jones), Holland and Xanthomonas axonopodis Hasse. In antioxidants assays, 10, 20 and 30 mg mL-1 extracts were used keeping DPPH as control. In these bioassays, ethyl acetate fraction of A. viridis leaf exhibited the best antibacterial and antioxidants activity. Ethyl acetate leaf fraction showed the highest inhibition zone diameter (IZD) where it caused 21 mm IZD against P. syringae and 19 mm IZD against E. carotovora. This extract also showed 22, 52 and 84% antioxidant activity at 10, 20 and 30 mg mL-1 concentrations, respectively. Previously there is no report available that describes antibacterial activity of root extract of A. viridis against P. syringae. Moreover, antioxidant activity of stem and root extracts in n-hexane, chloroform and ethyl acetate was investigated first time in the world. It was concluded that the biological activities observed during the present investigation may be due to the presence of bioactive constituents that can be harnessed as natural antibacterials and antioxidants.
