TL;DR: Three essential oils from three samples: fresh, air-dried and processed flowers of Chrysanthemum indicum, obtained by hydrodistillation, were analyzed by GC-MS and showed that both essential oils possessed significant antimicrobial effect, however, some difference in antimicrobial activity between two oils was observed.

TL;DR: The data suggest that the essential oil of A. tsao-ko could be a potential medicinal resource and has weak antioxidant activity as measured by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical assay, thiobarbituric acid (TBA) test and ferric reducing antioxidant power (FRAP) assay.

TL;DR: The antimicrobial assays showed CSAP could inhibit the growth of Gram-positive and Gram-negative bacteria but no significant inhibition against fungi or yeasts, and the antibacterial activity was not bactericidal but bacteriostatic.
Abstract: An antibacterial protein was isolated from the cultured mycelia ofCordyceps sinensis, and was designated asCordyceps sinensis Antibacterial Protein (CSAP). CSAP was single-chained, with an apparent molecular mass of 35×103 revealed by SDS-PAGE and a novel hydrophobic N-terminal sequence N-ALATQHGAP. The antimicrobial assays showed CSAP could inhibit the growth of Gram-positive and Gram-negative bacteria but no significant inhibition against fungi or yeasts. Furthermore, the antibacterial activity of CSAP was not bactericidal but bacteriostatic. It was the first time that an antibacterial protein was described in theCordyceps species, which might involve in the chemical defense mechanism of the hosts.

TL;DR: Findings suggest that, at least in part, the encountered beneficial effects of essential oils are due to prooxidant effects on the cellular level.
6,174 citations
TL;DR: A review of the bio-active properties of essential oils and their medicinal potential is presented in this article. But, the review is limited to essential oils extracted from plants by steam distillation and various solvents.
838 citations
TL;DR: The use of eucalyptus oil as a natural pesticide is of immense significance in view of the environmental and toxicological implications of the indiscriminate use of synthetic pesticides and overcoming/reducing the problem of increasing pest resistance.

TL;DR: In this review, antimicrobials from a range of plant, animal, and microbial sources are reviewed along with their potential applications in food systems and factors influencing the antimicrobial activity of such agents are discussed including extraction methods, molecular weight, and agent origin.
Abstract: In this review, antimicrobials from a range of plant, animal, and microbial sources are reviewed along with their potential applications in food systems. Chemical and biochemical antimicrobial compounds derived from these natural sources and their activity against a range of pathogenic and spoilage microorganisms pertinent to food, together with their effects on food organoleptic properties, are outlined. Factors influencing the antimicrobial activity of such agents are discussed including extraction methods, molecular weight, and agent origin. These issues are considered in conjunction with the latest developments in the quantification of the minimum inhibitory (and noninhibitory) concentration of antimicrobials and/or their components. Natural antimicrobials can be used alone or in combination with other novel preservation technologies to facilitate the replacement of traditional approaches. Research priorities and future trends focusing on the impact of product formulation, intrinsic product parameters, and extrinsic storage parameters on the design of efficient food preservation systems are also presented.

TL;DR: A survey of the methods generally used for the evaluation of antioxidant activity and some of the mechanisms involved in the anti-inflammatory activities of essential oils are reported.
Abstract: Essential oils are complex mixtures isolated from aromatic plants which may possess antioxidant and anti-inflammatory activities of interest in thye food and cosmetic industries as well as in the human health field. In this work, a review was done on the most recent publications concerning their antioxidant and anti-inflammatory activities. At the same time a survey of the methods generally used for the evaluation of antioxidant activity and some of the mechanisms involved in the anti-inflammatory activities of essential oils are also reported.
