“…This result indicates that phenolics components contribute substantially, in case of TPC/RP in particular, to the AP of date fruit. Sanda et al (2015) found a positive correlation between TPC/DPPH scavenging activity (R 2 =0.811) and TPC/RP (R 2 =0.707) of two Daphne species from Turkey. Also, Abbès et al (2013) observed a presence of correlation between the AA and TPC of date syrup.…”

“…Total flavonoid content was also determined spectrophotometrically at 510 nm with slight modification [27]. 1 mL methanolic solution of extract (1 mg/mL) or standard solutions of quercetin (10,20,40,60,80, 100 μg/mL) was added to 0.5 mL of 5% NaNO 2 solution and 0.5 mL of 10% AlCl 3 solution. After 5 min, 2 mL of 4% NaOH solution was added and incubated for 15 min at room temperature and the absorbance was measured against the blank at 510 nm with an UV-VIS spectrophotometer (Lambda 35, Perkin Elmer, USA).…”

“…The human bodies are always in a constant attack by free radicals or highly reactive atoms or species and as a result the chain reaction starts in a cell which ultimately can cause damage or even death to the cell in the body. Antioxidants can inhibit or terminate these chain reactions by removing free radicals, and inhibit other oxidation processes and ultimately prevent the progress of chronic diseases such as cancer, heart disease, stroke, cataracts and premature aging [10][11][12][13]. Antioxidants include both synthetic and natural.…”

Aim: The aim of present study was to investigate the nutritional composition, phytochemical constituents and in vitro antioxidant activities of a wild edible fruit in order to document data for further basic research needs or to widen its use among common people. Methods: The fresh fruits of Grewia sapida Roxb. ex DC. were collected from the Chirang district of Bodoland Territorial Area Districts of Assam, identified and freeze dried. Proximate composition, minerals content and phytochemical constituents were analyzed following standard and reported methods. The antioxidant activities of methanol extract were evaluated by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and 2, 2'-Azinobis (3-ethylbenothiazoline-6-sulfonic acid) diammonium salt (ABTS) assays. Results: The results obtained were reported and discussed. The phytochemical screening of different solvent extracts revealed that fruits contained a number of medicinally active secondary metabolites. The study showed antioxidant properties having IC 50 value of 257.666 ± 2.516 μg/mL (DPPH) and 134.33 ± 4.041 μg/mL (ABTS). The total phenolic and flavonoid contents in G. sapida fruit were found to be 294.353 ± 4.696 mg GAE/g dried extract and 116.95 ± 10.71 mg QE/g dried extract respectively. Conclusion: The study suggests that G. sapida fruit could be a good source of minerals and natural antioxidants, and studied further for its beneficial effect in human health.

In the context of climate change, the Ivorian cotton industry is facing with the loss of sensitivity of pests (Helicoverpa armigera) and the appearance of new so‐called emerging insects. Faced with this situation, cotton producers tend to use insecticide products in high doses, in excess of the norm. However, the misuse of chemical products poses many health risks. Therefore, to limit the use of chemicals, aqueous extracts of local plants with insecticidal properties were examined in the laboratory and in the field. Four local plant species were selected [Anacardium occidentale (Anarcardier); Azadirachta indica (Neem); Hyptis suaveolens (Hyptis) and Tephrosia vogelii (Tephrosia)]. After determining the chemical profiles of the four extracts by high performance liquid chromatography (HPLC)‐mass spectrometry, their inhibitory activities were assessed in cholinesterase and tyrosinase. The sensitivity of Helicoverpa armigera larvae was evaluated by ingesting the aqueous extracts at several concentrations ranging from 2% to 64% in an artificial nutrient substrate. Then, the mortality rates of the larvae during 72 h were evaluated and the lethal concentrations were determined. The results of chemical analyses (HPLC) showed that the richest aqueous extract in phytochemicals with 54 elements detected was that of cashew (A. occidentale). T. vogelii, A. indica and H. suaveolens presented 44, 45, and 39 chemical compounds, respectively. In addition, the total phenolic content was higher in A. occidentale (110.67 mg gallic acid equivalents/g) followed by A. indica (42.43 mg gallic acid equivalents/g). The highest antioxidant ability was observed with the aqueous extract of cashew (A. occidentale). Anti‐enzymatic activities such as acetylcholinesterase, butyrylcholinesterase and tyrosinase inhibition were most pronounced in A. occidentale (2.35 ± 0.02 mg galanthamine equivalent/g, 3.77 ± 0.01 mg galanthamine equivalent/g and 71.28 ± 0.07 mg kojic acid equivalent/g, respectively). The most toxic aqueous extract for H. armigera larvae was that of cashew with a lethal concentration LC50 = 11.68%. Moreover, the principal component analysis performed showed that the insecticidal activity is strongly correlated with the antioxidant and enzymatic activities of the aqueous extracts. Then, the hierarchical ascending classification showed cashew as the best plant. For the sustainability of cotton production, it would be necessary to limit the use of chemical‐synthetic insecticides through the use of plant extracts, especially from cashew leaves.
