“…However, when we expand our view to heavy metals content, it can be seen that celery accumulated higher doses of As, Cd, and Ni, therefore, a more potent free radical scavenging capacity in celery can be a result of high ROS production and oxidative stress occurred as a consequence of pollution. The influence of various heavy metals on the activation of defense machinery in terms of scavenging excess ROS production has been reported by a number of studies [32][33][34]. Apart from that, the slightly higher ability for lipid peroxidation inhibition observed in the celery extract can also be explained by higher TEs accumulation.…”

Celery (Appium graveolens L.) and parsley (Petroselinum crispum (Mill.) Fuss) are herbs utilized in the everyday diet as spices and culinary flavorings, often used in the chemical and medicinal industries. Despite the knowing benefits of different plants from the Apiaceae family, their chemical composition is closely associated with various extrinsic factors. Environmental loading with trace elements (TEs) can modify a plant’s metabolic pathways, change bioactive compounds production, cause plant pollution, and consequently provoke human health issues. Therefore, we established this research aiming to unravel the linkage between TEs accumulation and phenolic status in celery and parsley. Higher As, Cd, and Ni levels were observed in celery, which was followed by greater DPPH∙ radical scavenging activity and higher coumarins content. Contrary, parsley accumulated chromium to a greater extent, was richer in flavonoids, apigenin, and its glucosides. No significant difference between species was found in total phenolic contents, where ferulic and chlorogenic acid dominated in both species. A direct relationship between TEs and selected secondary metabolites was proven by the standardized major axis model. Besides abundant bioactive compounds, analyzed plant species showed a moderate hazard index in the children population, since the hazard index was higher than 1. Therefore, future perspectives should be turned towards the production of genotypes with a lower potential for toxic elements accumulation, so the health benefits of plant food will be more prominent.

“…Although there are 15 kinds of TCM compounds containing Akebiae Caulis in the 2015 edition of the Chinese Pharmacopoeia, an identification method of Akebiae Caulis is not specified (3). Aristolochic acid (AA), which is found in many Aristolochiaceae species, is nephrotoxic (20).…”

“…Regulators require product labels to include all product information. However, Chinese herbal medicinal products may be adulterated with impurities or contaminants during cultivation and processing (3). The general methods which can detect specific compounds in TCM are recorded in the Pharmacopoeia of the People's Republic of China (2015 Edition) (4), and are based on morphology, microscopic identification, thin-layer chromatography (TLC), and highperformance liquid chromatography (HPLC).…”

“…Aristolochiae Manshuriensis Caulis (Guan Mutong) and Clematidis Armandii Caulis (Chuan Mutong), which are nephrotoxic and carcinogenic, are often misused as Akebiae Caulis (12,13). However, the 2015 edition of the Chinese Pharmacopoeia did not describe a detection method of Akebiae Caulis in the TCM compounds (3). The misuse of the Akebiae Caulis, Clematidis Armandii Caulis, and Aristolochiae Manshuriensis Caulis will cause serious safety issues (14)(15)(16).…”

Background: Akebiae Caulis (Mu Tong) is commonly misused by Aristolochiae Manshuriensis Caulis (Guan Mutong) and Clematidis Armandii Caulis (Chuan Mutong), which are nephrotoxic and carcinogenic. However, in the Pharmacopoeia of the People's Republic of China (2015 Edition), the method for determining Akebiae Caulis remains undefined. Methods: We used DNA barcode-based next-generation sequencing (NGS) combined with quantitative real-time polymerase chain reaction (qPCR) to detect Akebiae Caulis in Longdan Xiegan Wan (LDXGW) for the first time. Compared with chromatographic studies, NGS enables better evaluation of the ingredient components of traditional Chinese medicine (TCM) preparations. The feasibility of qPCR using speciesspecific primers to determine the authenticity of species has been validated. In this study, the constituents of Akebiae Caulis in LDXGW from three different manufacturers were scanned by NGS. The independently developed qPCR detection primers of Akebiae Caulis, Aristolochiae Manshuriensis Caulis, and Clematidis Armandii Caulis were specifically used to analyze the LDXGW mentioned above. Results:The results showed that qPCR detected Clematidis Armandii Caulis in all commercial samples. Meanwhile, NGS detected the counterfeit species Clematis peterae (Tie-Xian Lian) in all samples. We found that qPCR shows a difference in detecting Akebiae Caulis, but it was not able to identify the unknown additives and adulterants for the primer pairs of Clematidis Armandii Caulis.Conclusions: Hence, it is sensitive and rapid, qPCR is not suitable for detection alone. The NGS approaches offer important novel insights that complement the qPCR method. The combination of NGS and qPCR will be a powerful complement to traditional identification methods of TCM substances.

“…The long-term exposure of humans to high concentrations of Hg, Cu, Pb, Cd, and Zn is known to cause several health concerns including major damage to the circulation, immune and reproductive system, liver failure, diabetes, mucosal irritation, kidney failure, and irritation of the central nervous system [ 7 , 8 , 9 , 10 , 11 ]. The United States Environmental Protection Agency (US EPA) has set the maximum daily intake of 0.004, 0.001, 0.0001 and 0.04 mg/kg of Pb, Cd, Hg and Cu, respectively [ 12 ]. In drinking water, US EPA has set the maximum contaminant level for Hg, Cd and Cu at 0.03 µg/L [ 13 ], 5.0 µg/L [ 14 ], and 1.3 mg/L [ 15 ], respectively.…”

Kapok fiber (Ceiba pentandra) belongs to a group of natural fibers that are mainly composed of cellulose, lignin, pectin, and small traces of inorganic compounds. These fibers are lightweight with hollow tubular structure that is easy to process and abundant in nature. Currently, kapok fibers are used in industry as filling material for beddings, upholstery, soft toys, and nonwoven materials. However, kapok fiber has also a potential application in the adsorptive removal of heavy metal ions and dyes from aqueous systems. This study aims to provide a comprehensive review about the recent developments on kapok fiber composites including its chemical properties, wettability, and surface morphology. Effective and innovative kapok fiber composites are analyzed with the help of characterization tools such as scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, thermogravimetric analysis, Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, and Brunauer-Emmett-Teller analysis. Different pre-treatment methods such as alkali and acid pre-treatment, oxidation pre-treatment, and Fenton reaction are discussed. These techniques are applied to enhance the hydrophilicity and to generate rougher fiber surfaces. Moreover, surface modification and synthesis of kapok fiber-based composites and its environmental applications are examined. There are various methods in the fabrication of kapok fiber composites that include chemical modification and polymerization. These procedures allow the kapok fiber composites to have higher adsorption capacities for selective heavy metal and dye removal.
