TL;DR: In this article, two complementary colorimetric methods, aluminum chloride method and 2,4-dini trophenylhydrazine method, were used to determine the real content of total flavonoids in propolis.

TL;DR: In this paper, the authors compared the performance of three types of technologies, namely, METHANOL, WATER, and ACETONE, in three different STEM environments: STEM, STEM, and LEAVES of BoCCOLI.

TL;DR: In this review, the source s of the pyrrolizidine alkaloid-containing Chinese herbal plants in China and the toxicity, genotoxicity, and tumorigenicity of these co mpounds are discussed and the metabolic pathways, particularly the activation pathways leading to genot toxicity, are discussed.

TL;DR: The structure of Taiwan’s National Health Insurance (NHI) research databases is presented, along with the comparison with automated databases in other countries, and the strengths and weaknesses of the NHI research databases are estimated to reveal.

TL;DR: The results suggested that histidine-containing compounds were related to antioxidation abilities, and the peptid e linkage between β-alanine, histidine and 1-methylhistidine was involved in the antioxidant activities of carnosine and anserine.

TL;DR: HPP possesses huge potential in the development of novel health foods and may provide an abundance of benefits to human health in the future.

TL;DR: In this paper, a simple and rapid method was developed to determine ethanol content in alcoholic beverages using megapore polar column (CPWax 58 CB, 30 m ∞ 053 mm) with direct injection gas chromatography Contrary to packed GLC method, distillation and/or stepwise dilution of samples were not necessary by the method developed in this study.

TL;DR: Results show that local lactobacilli strains have strong antioxidative and anticancer activities.

TL;DR: For example, derivatization of drugs prior to their GC-MS analysis is often used to bring the analytes to the chemical forms that are more compatible to the chromatographic environment as discussed by the authors.

TL;DR: In this paper, the concentrations of trace metals (Pb, Cd, Cr, Ni, Fe, Cu, Mn and Zn) in spice samples from Turkey were determined because similar studies have not been published.

TL;DR: This review focused on gas chromatography-mass spectrometry (GC-MS)-based methods and introduced several biomedical studies that measured fatty acid levels in different sample matrices and provided hints on the relationships between fatty acid imbalances and diseases.

TL;DR: This study aimed to determine the aflatoxin levels in red scaled, red and black pepper and found that aflatoxins continue to pose a health concern via human exposure to contaminated spices.

TL;DR: In this paper, the phenolic content and antioxidant activity of grape (Vitis vinifera) seed powder extracted by in vitro physiological procedure and chemical procedure were investigated, and the antioxidant potential of the extract were assessed by employing different in vitro assays such as CUPRAC, DPPH, ABTS, OH radical scavenging capacity, and peroxidation inhibiting activity.

TL;DR: Traditional Chinese medicine (TCM) has been playing a major role in health care in China for millennia but Morphological and histological authentication is not precise enough to authenticate those herbs which are possibly substituted or adulterated by plants with similar shapes and tissue constructs.

TL;DR: Most of the compounds achieve the hypopigmenting effect by inhibiting tyrosinase; however, some interesting compounds blocking the upstream regulation points of melanogenesis are extraordinarily promising for developing novel whitening agents.

TL;DR: In this paper, the concentrations of trace heavy metals (Pb, Cd, Fe, Cu, Mn and Zn) in 15 different honey samples collected from 15 different farms in Middle Anatolia, Turkey, were determined by flame and graphite furnace atomic absorption spectrometry after microwave digestion.

TL;DR: Conjugation of phytosterols with docosahexaenoic acid (DHA) was found to lower cholesterol in a mouse model and esters of epigallocatechin gallate with docoshexaenosic acid were able to arrest colon cancer in mice.

TL;DR: In this paper, the authors focused on the application of near infrared (NIR) spectroscopy in conjunction with multivariate calibration to identify the adulteration of olive oils.

TL;DR: Wang et al. as discussed by the authors examined water extracts from beefsteak plant stems (BS), leaves (BL), and ripe seeds (BR) for their antioxidant activities and phenolic compounds.

TL;DR: Nine species of the most commonly found fishes in the Ann-Ping coastal waters, were selected and analyzed for the Zn, Fe, Cu, M n and Cd concentrations in the muscles, livers and gonads; followed by Cu and Mn, Cd being the lowest in the three kinds of fish tissues.

TL;DR: Findings of phytochemicals in cancer chemoprevention via several distinct strategies are summarized to highlight promising treatments and to encourage new ideas for future studies.

TL;DR: It is suggested that mycotoxin contamination should be routinely monitored in foods for babies in order to reduce food-borne hazards in infants and young children.

TL;DR: Quercetin sulfates and quercet in glucuronides represent the major metabolites either rutin or quercETin was administered to rats, and QuercetIn showed higher oral absorption rate than rut in this study, and the pharmacokinetic parameters were calculated using noncompartment model of WINNONLIN.
