“…The antioxidant activity of Eucalyptus essential oils evaluated by various testing methods had been reported in earlier studies. The antioxidant activity of E. globulus essential oil evaluated by ORAC assay resulted in higher values than the values previously reported by Miguel et al [ 81 ]. However, the antioxidant activity of E. nitens has not been investigated in the literature.…”

“…According to the results presented in Figure 2 , the antioxidant activity of the Eucalyptus essential oils did not show significant differences between the two studied species ( E. globulus and E. nitens ) and the two different collection periods. Neither did Miguel et al [ 81 ] find significant differences among antioxidant activity (ORAC and TEAC methods) of E. globulus and some other Eucalyptus species. The most antioxidant active components of essential oils were thymol and carvacrol (oxygenated monoterpenes) [ 27 , 82 , 83 ].…”

Increasing applications and markets for essential oils could bring new opportunities for cost-effective and sustainable management of unused forestry biomass; however, better knowledge of the production and application of such essential oils is necessary. The objective of this work is to contribute to greater knowledge of the essential oil production on a pilot scale from foliage biomass of wild shrubs and tree residues produced in some forestry enhancement operations and to study their antioxidant capacity (ORAC—oxygen radical absorbance capacity). Fresh biomass (twigs) of seven species (E. globulus, E. nitens, P. pinaster, P. sylvestris, R. officinalis, C. ladanifer, and J. communis) was manually collected in Spain in two different periods and was ground at 30 mm and distilled in a 30 L stainless steel still with saturated steam. The essential oil components were identified by GC–MS and quantified by GC–FID, and their antioxidant activity was determined with the ORAC method. Promising results on essential oil yield were obtained with E. globulus, E. nitens, R. officinalis, and J. communis. All essential oils studied exhibited antioxidant capacity by the ORAC assay, particularly that from C. ladanifer. Moreover, oxygenated sesquiterpenes contents, one of the minor components of oils, were significantly correlated with ORAC values.

“…For example, Miguel et al (2018) showed that 1,8-cineole, which constituted 3.2% of C. nervatus oil, has a low effect on THP-1 human leukaemia cells. However, the antiproliferative activity increased in the presence of p-cymene (representing 3.1% of C. nervatus oil) supporting the concept of a synergistic effect of both molecules.…”

Essential oils from the inflorescence of Cymbopogon schoenanthus and C. nervatus growing in Northern Sudan were examined for their chemical composition, antiproliferative activity against human breast carcinoma and human colon adenocarcinoma cell lines, antioxidant activity (phosphomolybdenum, antiradical, reducing power, and ferrous chelating), and enzyme inhibition activity against acetylcholinesterase butyrylcholinesterase, tyrosinase, α-glucosidase, and α-amylase. In silico study on the inhibition of tyrosinase and α-amylase was also performed. Piperitone (59.1%) andisomers of para-menthadienols (35.3%) were the main compounds in C. schoenanthus and C. nervatus oils, respectively. Oil from C. nervatus possessed higher antioxidant activity than that from C. schoenanthus except for its metal chelating ability.Both oils showed high antiproliferative activity. In silico study showed that transp-mentha-2,8-dien-1-ol and piperitone (both isomers) revealed the best docking scores for α-amylase and tyrosinase, respectively. In conclusion, oils from these two Cymbopogon species could be new natural agents with functional properties for food, cosmetics, and pharmaceutical industries. Practical applicationsRecently, there is a growing tendency to replace synthetic oils by natural ones in the cosmetic, food, and pharmaceutical products. In this context, we investigated the chemical characterization and biological activities of two Cymbopogon species essential oils (C. schoenanthus (L.) Spreng. and C. nervatus). Antioxidant capacity, enzyme inhibition, and antiproliferative effects were tested for biological activities. Chemical characterization was identified by GC-MS. Based on our findings, the Cymbopogon species may be utilized as sources of natural bioactive agents in food industries.

“…29 Meanwhile, these species have been reported as antiviral plants due to their high contents in the Eos and other constituents, which give them potential inhibition against viral replication. 30 Family Lamiaceae is the most effective family in the treatment of HAV; species belonging to this family characterized by the presence of volatile oils, and these oils are used in the treatment of many diseases since a long time ago and till now, 31 found that the volatile oils in Eucalyptus species can be used as antibacterial, antioxidant, and antiproliferative activities. They reported the importance of these species, with high contents of volatile oils, in supporting the body's immune system.…”

Background: Folk Egyptian medicine considered from the most important source of the use of wild plants in medication. Wild plants are considered a perfect source of natural compounds that have been used as antimicrobial andante virus activities. Aims and Objective: The aim of the current study was to investigate the effect of the commonly used wild plants in the treatment of jaundice and they effect on HAV. This article provides much-needed insight into the effect of wild plants on the hepatitis A virus to shed more light on the important subject, which is unfortunately poorly investigated. Materials and Methods: In this investigation, the aqueous plant extracts of twenty-five wild Egyptian species, 16 perennials, and 9 annuals; three concentrations, 1%, 3% & 5%; were tested for HAV replication by using PA and PCR techniques. Questionnaires and interviews with Bedouins have been carried to know the most used species in the treatment of jaundice, and the usage values were calculated. Those species were collected from their habitats, rare ones purchased and reviewed their identifications and used in this work. Fecal and blood samples were taken from 9-10Y old patients, 35 girls and 25 boys. Results: The PA test revealed that 16 species out of twenty-five gave positive results, while the rest of the species gave negative results on Vero cells. Twelve of the sixteen species were perennial species, and the rest are annuals. The Plaque assay results showed that the most effective aqueous extract species, with the three concentrations, on HAV activity were those of Salvia verbennaca, Mentha microphylla, Ocimum basilicum, Cassia senna, Solenostemma argel, and Thymus capitatus, respectively. PCR test has been carried for the first three species and gave very faint nucleic acid tapes, which means that the plant extract of these species, the three concentrations, minimize the virus activity by a way or another. Samples from the patients tested for the antibodies for IgM and IgG using the ELISA test. Within both the females (58%) and males (42%), 6% have positive antibodies for IgM, while 36% in females and 34% in males’ have positive antibodies for IgG and 8% females and 10% males have both antibodies (IgM & IgG). Conclusion: Wild plants, especially those with essential oils can tolerate the Hepatitis A virus (HAV) activity and reduce its symptoms.
