“…Briefly, our study confirmed previous findings reported by Boughalleb et al, [18] , Al-Saeghi et al, [28] Agour et al, [29] Sharifi-Rad et al, [30] Benchikha et al, [31] and Makhlouf-Gafsi et al [32] Generally, to assess the antioxidant potential of bioactive extracts, several factors are involved such as solvent polarity, extraction methods, plant matrix and especially phenolic compounds containing including caffeic acid, 4-feruloylquinic acid, flavonoids, alkaloids and carotenoids.

Phytochemical screening of aqueous extract from six medicinal wild plants grown in South‐eastern of Tunisia: Atriplex halimus, Teucrium polium, Moricandia arvensis, Deverra tortuoa, Haplophyllum tuberculatum and Polygonum equisetiforme were evaluated. Both decoction and ultrasound assisted extraction were used. Antioxidant, antibacterial proprieties, and phenolic profiling, using LC‐ESI‐MS method, were assessed. Total polyphenols, flavonoids, and condensed tannins contents ranged from 7.47±0.19 to 22.25±0.49 mg GAE/g Dw, 5.47±0.06 to 7.55±0.07 mg RE/g Dw, and 0.33±0.02 to 19.43±0.64 mg TAE/g Dw, respectively. Moreover, the reducing power and DPPH tests showed that P. equisetiforme (EC50: 12.50±0.50 μg/ml; DPPH⋅+: 213.49±4.24 mg TEAC/g DW), T. polium (EC50: 25.00±1.00 μg/ml; DPPH⋅+: 181.39±9.47 mg TEAC/g DW) as well as H. tuberculatum (EC50: 56.25±0.25 μg/ml; DPPH⋅+: 177.83±5.85 mg TEAC/g DW) extracts were the most effective natural antioxidants. For anti‐bacterial activity, the ultrasonic extract of H. tuberculatum showed the highest activity against both P. aeruginosa (13.50±0.71 mm) and S. aureus (13.00±0.00 mm) at 10 mg/ml. Furthermore 24 phenolic compounds were identified, with predominance of quinic acid, gallic acid, protocatechuic acid, syringic acid, p‐coumaric acid, trans‐ferulic acid, catechin (+), trans‐cinnamic and silymarin. These results were further consolidated by to heatmap clustering with P. equisetiforme, H. tuberculatum, T. polium as the main antioxidant and antibacterial sources which supports their domestication and industrial use.

“…Furthermore, plants have a significant impact on diet in both societal (i.e., veganism) but also in practical contexts in relation to human physiology. The nutritional and medicinal benefits of plants are reflected in their phytochemical components, as plants are able to synthesise a large range of compounds known as phytochemicals [3][4][5]. The metabolites of plants are categorised into two groups: primary and secondary metabolites.…”

Medicinal and herbal plants are abundant sources of phytochemicals, which are biologically active compounds with potential health benefits. The characterisation of phytochemicals has been the subject of many studies, but there is a lack of comprehensive assays to accurately assess the main phytochemical categories and their antioxidant properties. To address this, the present study has developed a multiparametric protocol comprising eight biochemical assays, which quantify the major categories of phytochemicals, including polyphenols, tannins and flavonoids, as well as their antioxidant and scavenging potential. The presented protocol offers several advantages over other methods, including higher sensitivity and significantly lower cost, making it a simpler and more affordable approach compared to commercial kits. The protocol was tested on two datasets with seventeen distinct herbal and medicinal plants, and the results demonstrated its effectiveness in accurately characterising the phytochemical composition of plant samples. The modular design of the protocol allows its adaptation to any spectrophotometric instrumentation, while all assays are simple to follow and require a minimum number of analytical steps.
