“…All the samples and standard were packed and irradiated together for 6 h at a thermal neutron flux of 4.5 × 10 13 cm −2 s −1 . After appropriate cooling, the irradiated samples together with the standard were measured at different cooling times using a coaxial HPGe detector having the following characteristics: relative efficiency of 35% and FWHM 1.8 keV for the 1332.5 keV γ-peak of 60 Co. At the end, we determined the concentrations of the elements (major and trace elements) using the equation of INAA given by the Equation (1) [ 17 ].

where the subscripts a and s refer to the sample and the standard, respectively, N p is the net photo-peak counts, W is the sample mass, D = [exp (−λ t d )] is the decay factor, and C = ([1 − exp (−λ t m )]/λ t m ) is the counting factor, λ decay constant, t c , t d and t m counting, decay and measurement times, respectively.…”

“…However, there is increasing need to provide a scientific basis for the traditional use of different plants and plant parts. For this reason, this study aimed to provide in-depth information on the extraction of essential oil, methanolic extract, biological activities, and mineral compositions of Mentha pulegium L. It is part of an overall program in our laboratory for studying natural food samples relevant to human health and nutrition [ 16 , 17 , 18 , 19 , 20 , 21 ]. The results of this study will be useful in enriching the database of Algerian medicinal herbs, advancing the knowledge on medicinal plants, and deepening the scientific understanding of the medicinal, elemental, and bioactive compounds and antimicrobial properties of Mentha pulegium .…”

Our study evaluated the in vitro antioxidant properties, antibacterial and antifungal activities, anti-inflammatory properties, and chemical composition of the essential oils (EOs), total phenol, and total flavonoid of wild Mentha pulegium L. This study also determined the mineral (nutritional and toxic) elements in the plant. The EOs were extracted using three techniques—hydro distillation (HD), steam distillation (SD), and microwave-assisted distillation (MAD)—and were analyzed using chromatography coupled with flame ionization (GC-FID) and gas chromatography attached with mass spectrometry detector (GC-MS). The antioxidant effects of the EOs were tested with 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ABTS (2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid), while the antibacterial and antifungal activities of the EO and methanolic extract were tested using Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli, and Candida albicans. Twenty-six compounds were identified in the essential oil, representing 97.73% of the total oil, with 0.202% yield. The major components were pulegone (74.81%), menthone (13.01%) and piperitone (3.82%). Twenty-one elements, including macro- and micro-elements (Ba, Br, Ca, Cl, Co, Cr, Cs, Eu, Fe, K, Mg, Mn, Mo, Na, Rb, Sb, Sc, Sr, Th, U and Zn), were detected using neutron activation analysis (INAA) and inductively coupled plasma optical emission spectrometry (ICP-OES), with the concentration of mineral element close to the FAO recommendation. The results show that the EOs and extracts from Mentha pulegium L. had significant antimicrobial activities against the microorganisms, including five human pathogenic bacteria, one yeast (Candida albicans), and one phytopathogenic fungi. The in vivo anti-inflammatory activities of the leaf extracts were confirmed. The results indicate that the EOs and extracts from Mentha pulegium L. have promising applications in the pharmaceutical industries, clinical applications, and in medical research.

“…Many types of research and pharmaceutical applications of medicinal plants, whether on extracts or volatile oils, have been conducted by many researchers around the world, resulting in great progress in treating various diseases. However, the absorption of minerals by herbs and plants, whether nutritional or toxic, varies highly in plants with the level of heavy metals in the soil, atmosphere, irrigation and water [44][45][46]. The results of these studies showed the large diversity of the tested extract in terms of mineral compounds.…”

Lobularia libyca (L. libyca) is a traditional plant that is popular for its richness in phenolic compounds and flavonoids. The aim of this study was to comprehensively investigate the phytochemical profile by liquid chromatography, electrospray ionization and tandem mass spectrometry (LC-ESI-MS), the mineral contents and the biological properties of L. libyca methanol extract. L. libyca contains significant amounts of phenolic compounds and flavonoids. Thirteen compounds classified as flavonoids were identified. L. libyca is rich in nutrients such as Na, Fe and Ca. Moreover, the methanol extract of L. libyca showed significant antioxidant activity without cytotoxic activity on HCT116 cells (human colon cancer cell line) and HepG2 cells (human hepatoma), showing an inhibition zone of 13 mm in diameter. In silico studies showed that decanoic acid ethyl ester exhibited the best fit in β-lactamase and DNA gyrase active sites; meanwhile, oleic acid showed the best fit in reductase binding sites. Thus, it can be concluded that L. libyca can serve as a beneficial nutraceutical agent, owing to its significant antioxidant and antibacterial potential and due to its richness in iron, calcium and potassium, which are essential for maintaining a healthy lifestyle.

“…However, sample preparation steps are inevitable prior to HPLC analysis due to the low contents of Se and various interferents in real samples. So far, a variety of microextraction technologies including liquid–liquid microextraction [10], ultrasound‐assisted liquid‐phase microextraction [11], dispersive liquid–liquid microextraction [12], SPME [13], and dispersive micro‐SPE [14] have been introduced to extract Se(IV) and Se(VI). Among them, SPME is alluring because it integrates entrapment, enrichment and clean‐up into one step, and displays some merits such as simple operation and low consumptions of sample and solvent.…”

An efficient multiple fibers solid‐phase microextraction method based on porous monolith was established for Se(IV) and Se(VI) analysis. Poly(4‐vinylphenylboronic acid/styrene‐co‐ethylene dimethacrylate/divinylbenzene) monolith was fabricated and employed as the extraction phase for efficient entrapment of Se(IV) complexed with o‐phenylenediamine, followed by elution with a methanol/formic acid (99/1.0, v/v) mixture and quantification by high‐performance liquid chromatography with diode array detector. The Se(VI) species was measured by the difference between total inorganic Se and Se(IV) after pre‐reduction. Different characterization techniques were employed to inspect the structure and morphology of prepared adsorbent. A series of key extraction factors were optimized so as to achieve the expected extraction performance. Under the optimized separation and capture parameters, the linear range and limit of detection for Se(IV) in water sample were 0.050–200 and 0.013 μg/L, respectively. For beer sample, the corresponding values were 0.010–300 and 0.032 μg/L. The developed microextraction approach was successfully utilized to detect trace Se(IV) and Se(VI) in environmental water and beer samples with satisfactory fortified recovery and repeatability. Results well reveal the attractive merits of the established method in the analysis of Se species, including simple preparation of adsorbent, convenient extraction procedure, good sensitivity, high cost‐effectiveness, and eco‐friendliness.
