Total-scale quantitative research literature analysis on the food toxicology scientific field has yet to be conducted. In this work, we identified and analysed food toxicology publications in the existing scientific literature. A literature search was performed with the online Web of Science database. Full records and cited references of the 73,099 identified manuscripts were imported into VOSviewer software for analysis. This research field has been growing steadily since the 1990s. Article to review ratio was 7.4:1. The publications were mainly related to toxicology, environmental sciences, food science and technology, pharmacology/pharmacy and biochemistry/molecular biology. The United States and China are major contributors to food toxicology research, followed by other European and Asian countries. The prolific authors have formed three major clusters within a citation network. Toxic or hazardous chemicals related to food with high citations included aflatoxin, dioxin, fumonisin, malondialdehyde, mycotoxin, ochratoxin, phthalate, and polychlorinated biphenyl.

Chlorogenic acid (CA), also known as 5- O -caffeoylquinic acid, is a dietary phenolic acid produced by various plant species. CA, is the most ubiquitous compound among the phenolic acid group, is also present in tea and green coffee extracts. Its consumption reduces the risk of numerous diseases as validated by preclinical and clinical studies. CA possesses a wide range of pharmacological properties, such as hepatoprotective, antimicrobial, immunomodulatory, antioxidant, antidiabetic, and anticancer activities. It has been extensively used in the food, chemical, medicine, and health care industries. Available reports revealed that CA can exert anticancer activity by inhibiting the cell cycle, triggering apoptosis, and suppressing the proliferation of cancer cells. It upregulates the expression of nuclear factor of activated T cells 2 (NFATC2) and NFATC3 genes involved in immune pathway and downregulates B cell-specific moloney murine leukemia virus integration site 1 protein and SRY-box transcription factor 2 gene expression to facilitate tumor cell destruction. It promotes intracellular DNA impairment and topoisomerase I- and topoisomerase-II-DNA complex formation that perform a key function in apoptosis. In addition, CA has been documented to be an effective natural anticancer drug and was approved by the China Food and Drug Administration. Several previously published reports have provided fragmented summary of various anticancer activities of CA. Therefore, this review aims to deliver up-to-date and comprehensive assessment about the natural sources of CA, its bioavailability, metabolism, and anticancer property with an emphasis on the molecular mechanisms associated with several signaling pathways in tumor cells.

The research into bioactive natural products originating from medicinal plants, fungi and other organisms has a long history, accumulating abundant and diverse publications. However no quantitative literature analysis has been conducted so far. Here we analyze the bibliometric data of ethnopharmacology literature and relate the semantic content to the publication and citation data so that the major research themes, contributors, and journals of different time periods could be identified and evaluated. Web of Science (WoS) was searched to identify relevant publications. The Analyze function of WoS and bibliometric software (VOSviewer) were utilized to perform the analyses. Until the end of November 2018, 59,576 publications -linked to 'ethnopharmacology' indexed by WoS, published since 1958 in more than 5600 journals, and contributed by over 20,600 institutions located in more than 200 countries/regions, were identified. The papers were published under four dominating WoS categories, namely pharmacology/pharmacy (34.4%), plant sciences (28.6%), medicinal chemistry (25.3%), and integrative complementary medicine (20.6%). India (14.6%) and China (13.2%) were dominating the publication space. The United States and Brazil also had more than 8.0% contribution each. The rest of the top ten countries/regions were mainly from Asia. There were around ten-fold more original articles (84.6%) than reviews (8.4%). Ethnopharmacological research has a consistent focus on food and plant sciences, (bio)chemistry, complementary medicine and pharmacology, with a more limited scientific acceptance in the socio-cultural sciences. Dynamic global contributions have been shifting from developed countries to economically and scientifically emerging countries in Asia, South America and the Middle East. Research on recording medicinal plant species used by traditional medicine continues, but the evaluation of specific properties or treatment effects of extracts and compounds has increased enormously. Moreover increasing attention is paid to some widely distributed natural products, such as curcumin, quercetin, and rutin. Image 1 [ABSTRACT FROM AUTHOR]
