Laboratory studies [64,65] also have shown that soil-applied 1,8-cineole suppressed the growth of several weeds. However, field reports demonstrated that 1,8-cineole alone has poor herbicidal activity [67,68].…”

BACKGROUND In recent decades, the use of synthetic herbicides has been increasing, mainly in emerging countries. However, their intensive and indiscriminate application is a major cause of environmental pollution and human health injury. Therefore, there is an increasing need to develop new herbicides with safer toxicological and environmental profiles. A promising strategy is to synthesize new molecules containing the core of natural products as a template for the production of ‘bio‐inspired’ or ‘natural‐like’ herbicides. RESULTS The potential herbicidal activity of some benzofuran‐2‐acetic esters was assessed in vitro on Arabidopsis thaliana, a model species. All five molecules (M1‐M5) showed significant phytotoxic activity, reducing both shoot and root system at low concentrations. In particular, methyl 2‐(5‐methoxybenzofuran‐2‐yl)hexanoate (M3) exhibited the highest phytotoxicity displayed against two crops and weeds, monocots (Zea mays L. and E. crus‐galli) and dicots (Lactuca sativa L. and Amaranthus retroflexus L.). The M3 activity was also compared with glyphosate, a common herbicide, showing a lower but similar activity. Moreover, the results evidenced that M3 was more effective in post‐emergency. CONCLUSION Readily synthesizable benzofuran‐2‐acetic esters possessing the benzofuran ring as ‘bio‐inspired’ core, show significant herbicidal activity making them very efficient even at low concentrations. They can be sprayed in liquid form, and the addition of adjuvants can improve penetration through the leaf cuticle. These results confirm the importance of these molecules as models for the development of new natural‐like herbicides. © 2019 Society of Chemical Industry

“…DPPH (1,1-diphenyl-2-picrylhydrazyl) radical-scavenging activity was measured according to Barton. [18] Scavenging efficacy was calculated as a percent of decolorization based on the corrected absorbances read at 515 nm. The standard Trolox equivalent antioxidant capacity at zero sample concentration (TEAC 0 ) was obtained by extrapolation to zero sample concentration by linear regression.…”

Pomegranate seed oil (PSO) and bitter melon extract (BM), used in folk medicine nowadays are available as dietary supplements, but information about consequences of their simultaneous usage are still scarce. This study aims to evaluate the influence of supplementation of rats’ diet with PSO separately or jointly with BM on the fatty acid (FA), cholesterol, malondialdehyde (MDA), and tocopherols concentrations in femoral muscles. Sprague‐Dawley rats (n = 36) are fed control diet (group C) or experimental diets supplemented only with 0.15 ml PSO/day (group G) or together with BM (group GM). After 21 weeks of supplementation, muscles are subjected to either gas (FA and cholesterol) or liquid (conjugated FA, tocopherols, and MDA) chromatographic analyses. Applied diets do not influence negatively health and welfare of animals. Conjugated linolenic acid (CLnA) isomers, predominating in PSO, are converted into ct/tc conjugated dienes (CD), with rumenic acid being the main CD, and incorporated into muscles. Supplementation of diet with PSO decreases the cholesterol and MDA contents in muscles. Influence of PSO and BM on activity of desaturases results in varied polyunsaturated FA (PUFA) content. Some PUFA may be converted into conjugated FA either exogenously or as a result of enzymatic or non‐enzymatic processes. Practical Applications: Dietary sources of conjugated linolenic acid isomer, e.g., PSO and BM, are known for their beneficial properties and thus willingly consumed world‐wide. Limited safety information of their simultaneous use is available despite their over‐consumption and may probably cause adverse effects. PSO and BM given to rats improves a lipid profile of femoral muscles, decreases cholesterol, increases polyunsaturated fatty acids and rumenic acid content, and counteracts lipid oxidation. These results may be a starting point for experiments conducted on farm animals considering their supplementation with PSO in order to possible improvement of nutritional value of their meat. After detailed surveys confirming beneficial influence of both supplements on human health and well‐being, these botanicals may be safely introduced into human diet. This study evaluates the influence of supplementation of rats’ diet with pomegranate seed oil separately or jointly with bitter melon extract on fatty acid, cholesterol, malondialdehyde, and tocopherols concentrations in femoral muscles. After 21 weeks of supplementation, muscles are subjected to either gas or liquid chromatographic analyses. Supplementation of diet with pomegranate seed oil decreases cholesterol and malondialdehyde contents.
