“…These two main polyphenol groups were subsequently divided into different sub-classes within themselves. [51] The analysis results revealed that the chestnut honey sample contained approximately 14 of the 19 standards studied and was rich in rutin flavonoids. Rhododendron honey was found to be rich in ferulic acid, catechin, gallic acid, and chrysin.…”

It is obvious that the oxidation process is an undeniable fact and when it comes to aging, one of the first solutions that come to mind is natural products. When it comes to natural products, both plants and bee products play an important, almost combative role against oxidation. For this purpose, natural products of both plant and animal origin were considered together in our study: Linden, green tea, aronia, wild grapes, myrtle, blueberries and basil, honey, pollen and propolis. Total phenolic content values of the extracts ranged between 49.28 and 3859.06 mg gallic acid equivalent/100 g, and propolis, green tea, chestnut flower and aronia samples were found to have the highest values. When looking at the NOS inhibition potential, it was determined that propolis, pollen and aronia samples had the highest percentage inhibition values of 98.11, 92.29, 83.44, respectively. Antioxidant activities of methanolic extracts were investigated using iron(III) reducing/antioxidant capacity (FRAP), 2,2‐Diphenyl‐1‐picrylhydrazyl (DPPH) radical scavenging activity test and NOS inhibition tests. The phenolic composition of methanolic extracts was tested using the RP‐HPLC‐UV (high‐performance liquid chromatographic method with ultraviolet) method with 19 phenolic standards.

“…Several research studies on the phytochemical composition of different extracts (alcoholic, hydroalcoholic), obtained by different extraction methods (Soxhelt extraction, ultrasound-assisted extraction, microwave assisted extraction) and using as plant material different lavender species (L. angustifolia, L. latifolia, L. x intermedia), have reported the presence of phenolic acids such as protocatechuic acid, gallic acid, rosmarinic acid, caffeic acid, p-coumaric acid and ferulic acid and flavonoids such as apigenin, luteolin, catechin, epicatechin, naringenin and myricetin. The concentration of each of these polyphenolic compounds varies according to different species and depends on the genotype, geographical origin, climatic conditions, growing conditions, harvesting time and extraction method [53][54][55]. The LA, LL and G90 hydroalcoholic extracts are a rich source of bioactive compounds belonging to the polyphenol class.…”

The aims of the present study were to evaluate for the first time the chemical composition and antioxidant, antibacterial, antifungal and antiproliferative potentials of the Romanian George 90 lavender species, as well as parental species, L. angustifolia and L. latifolia. The L. angustifolia, L. latifolia and George 90 essential oils were analyzed by GC-MS/MS and the L. angustifolia, L. latifolia and George 90 hydroalcoholic extracts were analyzed by HPLC-DAD. The antioxidant, antibacterial, antifungal and antiproliferative assays revealed that all the investigated species showed significant activities. The results highlighted the chemical composition and the promising biological potentials of the L. angustifolia, L. latifolia and George 90 lavender species, validating their ethnomedicinal value, which offers potential applications as natural drugs.

The excessive production of free radicals leads to their accumulation in the body and the occurrence of a phenomenon known as oxidative stress. It is important to note that natural antioxidants play a vital role in mitigating the harmful effects of such reactive species. [7][8][9][10][11][12][13][14] Therefore, the present study aims to evaluate the antioxidant activity, total phenolic and flavonoid contents, and mineral content of the aqueous, ethanol and acetone extracts of three Algerian medicinal plants namely; Haloxylon scoparium, Artemisia campestris (L.), and Juniperus phoenicea (L.). Materials and Methods Chemicals and reagentsFolin-Ciocalteu's reagent, 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical, ascorbic acid, 2,2′-azino-bis-(3-ethylbenzothiazoline-6sulfonic) acid (ABTS) were obtained from Sigma (St Louis, MO, USA). Sodium carbonate, gallic acid, aluminum chloride, rutin, potassium persulphate (K2S2O8), sulphuric acid, sodium phosphate, ammonium molybdate, ethanol, and acetone were obtained from Sigma-Aldrich (Munich, Germany). Plant materialsThe aerial parts of the study plants including Artemisia campestris, Haloxylon scoparium, and Juniperus phoenicea were collected from their natural habitats in Laghouat region, Algeria (Latitude: 33°47'59 '', Longitude: 2°51'54'', Altitude: 764 m), between the months of March and April, 2021. The voucher specimens were deposited at the Laboratory of Process Engineering, University of Laghouat, with the numbers LGP Ac/03/21, LGP Hc/04/21 and LGP Jp/04/21 for Artemisia campestris, Haloxylon scoparium, and Juniperus phoenicea, respectively. The plants were reduced to a fine powder using electric mill.
