The last 2 decades have witnessed a sustained increase in the study of plant-emitted volatiles and their role in plant-insect, plant-microbe, and plant-plant interactions. While each of these binary systems involves complex chemical and biochemical processes between two organisms, the progression of increasing complexity of a ternary system (i.e., plant-insect-microbe), and the study of a ternary system requires nontrivial planning. This planning can include an experimental design that factors in potential overarching ecological interactions regarding the binary or ternary system, correctly identifying and understanding unexpected observations that may occur during the experiment and thorough interpretation of the resultant data...

The First International Conference on Nanotechnology Applications and Implications of Agrochemicals toward Sustainable Agriculture and Food Systems was held in Beijing, China, on November 17-18, 2016 to address and exchange the latest knowledge and developments in nanotechnology of agrochemicals toward sustainable agriculture and food systems. World-leading scientists gathered to discuss a wide range of relevant topics. The purposes of this symposium introduction are to provide an introduction to the international conference, summarize in brief the contributions of papers that follow within this special issue of the Journal of Agricultural and Food Chemistry, provide a synthesis of conference outcomes, and suggest future directions, including an important role of converging science and technologies to advance sustainable agriculture, food, and natural resource systems...

Background: The research into bioactive natural products of medicinal plants has a long tradition, but ethnopharmacology as a well-defined field of research has a relatively short history, only dating back 50 years. Aims: With the fast development of this field and its global importance especially in the fast developing economies of Asia it is timely to assess the most influential articles (as measured by citations) and to identify important drivers and research trends in this field. Methods: Scopus was searched to identify relevant articles which were assessed by all three authors...

The 1st International Symposium on Phytochemicals in Medicine and Food (ISPMF 2015) was held in Shanghai, China, from June 26th to 29th, 2015. The 1st ISPMF was organized by the Phytochemical Society of Europe (PSE) and the Phytochemical Society of Asia (PSA). More than 270 scientists from 48 countries attended this meeting. The program of ISPMF 2015 consisted of 12 plenary lectures, 20 invited talks, and 55 short oral presentations in 16 sessions, including phytochemistry, phytomedicine, pharmacology, and application of phytochemicals in medicine and food...

The "oxygen radical absorption capacity" (ORAC) assay (Ou, B., Hampsch-Woodill, M., Prior, R.L. (2001). Development and validation of an improved oxygen radical absorbance capacity assay using fluorescein as the fluorescent probe. Journal of Agricultural and Food Chemistry 49, 4619-4626) is widely employed to determine antioxidant content of foods and uses fluorescein as a probe for oxidation by peroxyl radicals. Kinetic modeling of the ORAC assay suggests that the lag phase for loss of fluorescence results from equilibrium between antioxidant and fluorescein radicals and the value of the equilibrium constant determines the shape of the lag phase...

The self-prepared pectin hydroxamic acid has been reported to have antioxidant activities [Yang, S. S., Cheng, K. D., Lin, Y. S., Liu, Y. W., & Hou, W. C. (2004). Pectin hydroxamic acids exhibit antioxidant activities in vitro. Journal of Agricultural and Food Chemistry, 52, 4270-4273]. In this study, the galacturonic acid (GalA), the monomer unit of the pectin polymer, was esterified with acidic methanol (1N HCl) at 4°C with gentle stirring for 5days to get galacturonic acid methyl ester which was further reacted with alkaline hydroxylamine to get galacturonyl hydroxamic acid (GalA-NHOH)...

Dietary isothiocyanates and selenium (Se) can up-regulate thioredoxin reductase 1 (TR1) in cultured human HepG2 and MCF-7 cells [Zhang et al. (2003). Synergy between sulforaphane and selenium in the induction of thioredoxin reductase 1 requires both transcriptional and translational modulation. Carcinogenesis, 24, 497-503; Wang et al. (2005). Sulforaphane, erucin and iberin up-regulate thioredoxin reductase expression in human MCF-7 cells. Journal of Agricultural and Food Chemistry, 53, 1417-1421] at both the protein and mRNA levels...

Manuscripts collected in this 51st North American Chemical Residue Workshop (NACRW) Symposium issue of the Journal of Agricultural and Food Chemistry (JAFC) were originally presented at the 51st NACRW meeting. The 2014 NACRW JAFC symposium collects 14 publications representing the broad range of topics in chemical analyses presented at the 2014 meeting. These include the analysis of chemical residues and contaminants in food, environment, feed, botanical, and bee samples as well as the application of quality control/quality assurance protocols in routine and method development...

U.S. food imports have been increasing steadily for decades, intensifying the need for a rapid and sensitive screening technique. A method has been developed that uses foam disks to sample the surface of incoming produce. This work provides complimentary information to the extensive amount of published pesticide fragmentation data collected using LCMS systems (Sack et al. Journal of Agricultural and Food Chemistry, 59, 6383-6411, 2011; Mol et al. Analytical and Bioanalytical Chemistry, 403, 2891-2908, 2012)...

The 9th International Symposium on Poisonous Plants (ISOPP9) was held July 15-21, 2013, at the Inner Mongolia Agricultural University in Hohhot, Inner Mongolia Autonomous Region of China. The symposium consisted of three days of oral and poster presentations, followed by a tour of the Xilinhot Region of the Mongolian Grasslands, encompassing grazing conditions consisting of desert, grassland, and steppes. This was the first time that an ISOPP meeting has been held in Asia and provided an opportunity for visitors from outside China to become aware of livestock poisonings caused by plant species with which they were previously not familiar while at the same time demonstrating that many of the problems experienced around the world have a common etiology...

The papers in this special issue of Journal of Agricultural and Food Chemistry were originally presented at the 50th North American Chemical Residue Workshop (NACRW), formerly known as the Florida Pesticide Residue Workshop (FPRW). The 2013 meeting celebrated the rich history of 50 years of the FPRW and the birth of the NACRW, which in its name reflects the increased scope of the workshop to topics related to the analysis of all chemical residues and contaminants in food, feed, and environmental samples.

There have been a substantial number of studies suggesting possible health benefits from polyphenols in wine, especially red wine. These hypothetical effects, in addition to those of alcohol, are attributed by many to antioxidant and anti-inflammatory effects of the polyphenols. The aim of this paper was to map the scientific research on wine and health by using bibliographic analyses of papers published during the period 2002-2011. Papers were published in 535 different journals and in 106 different subject categories, the most productive journals being the Journal of Agricultural and Food Chemistry, Food Chemistry and Molecular Nutrition, and Food Research, and the most productive subject category being food science and technology...

The papers in this special issue of Journal of Agricultural and Food Chemistry were originally presented at the 49th annual Florida Pesticide Residue Workshop (FPRW). The FPRW is an annual meeting for scientists specializing in trace level analysis of pesticides, veterinary drug residues, and other chemical contaminants in food, animal feed, and environmental samples.

A large part of the research focus on food constituents in the 20th century was toward health-detrimental contaminants-pathogens, toxins, chemical residues, and some food additives. This is reflected in the publications in the Journal of Agricultural and Food Chemistry and other journals. This era witnessed the formation of the U.S. Food and Drug Administration (FDA) and Environmental Protection Agency (EPA) and the rise and fall of DDT and other synthetic chemicals, as well as a number of artificial sweeteners, preservatives, and coloring/flavoring agents that attracted consumer and government attention...
