“…Finally, Costus improved spermatozoa cell density and quality and decreased their deterioration and abnormalities by Ethephon. All of these beneficial effects of Costus on Ethephon‐intoxicated rats might be explained by the presence of many active antioxidant compounds, including flavonoids, steroids, and chlorogenic acid in Costus root extract, which may enable it to neutralize and reduce the accumulation of Ethephon‐induced free radicals in testicular tissue because testicular tissue and sperm plasma membrane are rich in polyunsaturated fatty acids. This makes them more liable to ROS damage, which induced spermatogenic damage, reduced sperm counts and motility, and reduced antioxidant enzyme activities .…”

This study was designed to evaluate protective effect of Saussurea lappa root aqueous extract against Ethephon (2-chloroethylphosphonic acid)-induced reproductive toxicity in rats. Control group received distilled water. Second group was given S. lappa extract at a dose 50 mg/kg bw.Third group was given Ethephon at a dose 200 mg/kg bw. Fourth, fifth, and sixth groups were given S. lappa extract before, with or after Ethephon administration, respectively. Ethephon intoxication significantly decreased serum levels of follicle stimulating hormone, luteinizing hormone, testosterone, and prolactin. Also, it significantly decreased sperms count, vitality, morphology index, total motility, progressive motility, and proliferating cell nuclear antigen protein expressions in spermatogonia. However, it significantly increased sperms abnormalities, testicular tissue and DNA damages, P53 protein expressions, noprogressive motility, and immotile sperms. In contrast, S. lappa extract ameliorated these alterations. These results indicated that S. lappa had potential preventive and curative effects against Ethephon-induced reproductive toxicity in rats.

“…Flavonoids are a kind of compounds widely distributed in plants as secondary metabolites (Zakaryan et al, 2017). An increasing number of studies have reported the extraction methods of flavonoids from different plant sources (Liu et al, 2016;Jing et al, 2016;Wang et al, 2017;Yang et al, 2017;Yu et al, 2017). Enzymeassisted extraction is established as an emerging technique to accelerate the release of bioactive components from plant materials, due to its advantages of high extraction yield, environmental compatibility, low energy requirement and simplified manipulation (Chen et al, 2011).…”

Corn bract is a corn-based agricultural waste material that distributed worldwide. In present work, response surface methodology was applied to optimize the cellulase-assisted extraction of Total Flavonoids from Corn Bract (TFCB), the in vitro antioxidant and antibacterial as well as the in vivo antioxidant activities of TFCB were investigated. Results showed that the optimal conditions for TFCB extraction were as follows: Amount of cellulase, 0.4% (w/w); incubation time, 2 h; liquid-to-solid ratio, 35: 1 mL/g; ethanol concentration, 71% (v/v); TFCB yield was 1.284±0.01%, which was 25.39% higher than that of heat reflux extraction. In addition, when compared with vitamin C, TFCB showed weaker in vitro free radical-scavenging capacities, but stronger antioxidant activities in mice. Moreover, TFCB also exerted certain inhibitory effects against Gram-positive bacteria. This study will provide an evidence for the potential of comprehensive utilization of discarded corn bract.

“…In this way, several studies have been reported about using tiger nut for enriching some food products and for recovering other interesting compounds, such as oils or flavonoids (Ezeh, Gordon, & Niranjan, 2016;Jing et al, 2016). However, the byproduct obtained from the tiger-nut milk process has been less studied as an ingredient for developing products.…”

Effect of tiger-nut (Cyperus esculentus) milk co-product on the surface and diffusional properties of a wheat-based matrix

The food processing industry generates huge volumes of waste and co-products which still contain valuable compounds. Tiger-nut milk production generates large amounts of a co-product with a high insoluble fibre content, which is interesting as a bioactive component from a nutritional viewpoint. This co-product is formed by two different tissues in composition, particle size and colour terms, so two different flours were obtained from them. Both flours were included in a wheat-based matrix at different substitution levels: 5%, 10% and 20% (d.b). The surface tension of matrices, and the wettability and diffusion of water and oil, were studied. The results showed the matrix's reduced capacity to interact with solvents, principally from the 10% substitution level, with diminished surface tension, and a longer time was needed for both water and oil to wet and diffuse.
