Tissue culture and cloning are valuable techniques in plant biology research as they enable the production of genetically identical plants, which may be utilized for many purposes, such as crop enhancement, plant breeding, and genetic manipulation. Helichrysum arenarium (L.) Moench, also known as immortelle or strawflower (Asteraceae), is a species of flowering plant in the sunflower family. In this study, the aerial part of two Clones (Clone A, Clone B) of H. arenarium were used to consider the effect of Clones on the phenolics, minerals, and antioxidant activities. The methanol extracts were analyzed and compared for phenolic compounds and antioxidant activities. Inductively coupled plasma-optical emission spectroscopy is a widely used method for the determination of a wide range of elements in plant materials, including macro and microelements. Calcium and potassium are the major mineral elements. The phenolics were identified and quantified using high-performance liquid chromatography combined with tandem mass spectrometry. The highest caffeic acid was determined in the methanolic extract, followed by protocatechuic aldehyde and protocatechuic acid.

We report a bithiophene-based fluorescence probe BDT (2,2'-(((1 E, 1'E)-[2,2'-bithiophene]-5,5'-diylbis(methaneylylidene))bis(azaneylylidene))bis(4-(tert-butyl)phenol)) for recognizing ClO. BDT selectively responded to ClO, leading to a blue fluorescence enhancement in a mixture of DMF/HEPES buffer (9:1, v/v). Importantly, BDT showed an ultrafast response (within 1 s) to ClO among the fluorescent turn-on chemosensors based on bithiophene.

This study aimed to investigate the nutritional value and potential for herbal tea production of two species . The analysis includes the quantification of lipids, proteins, organic acids (HPLC-MS), sugars (HPLC-MS), phenolic compounds (HPLC-MS-MS), volatile compounds (GC-MS), fatty acids (GC-MS), amino acids (HPLC-MS-MS), some minerals (ICP-MS), total phenolic content, and antioxidant activities of flowers (EBF) and thorns (EBT), as well as flowers (EPF) and thorns (EPT). The results indicate that EPF and EPT exhibit elevated levels of protein (11.

Rich in bioactive compounds, carbohydrates, fibers, minerals, and trace elements, apple pomace (AP) is a significant agro-industrial by-product, which pollutes and brings high management costs. The current study investigates the possibility of using an aqueous AP extract (APE) as the main ingredient in a jelly candy recipe, replacing artificial colors and flavors and improving its nutritional value. APE and formulated jelly candies were analyzed in terms of their phytochemical profile, antioxidant capacity, and color parameters.

Fruits are excellent sources of substrate for various fermented products, including fruit vinegars, which are typically produced by submerged fermentation. Some evidence suggests that fruit vinegar consumption can alleviate certain disorders, including hyperlipidemia, inflammation, and hyperglycemia. Fruit vinegars also have bacteriostatic and antihypertensive actions.

Background: The in vitro propagation of halophytes is innovative perspective for sustainable agriculture, conservation of natural plants and essential raw materials for industry due to increasing soil salinization and decreasing freshwater availability. Sarcocornia fruticosa, a halophytic plant, may hold promise for biosaline production systems and achieve bioactive products. Understanding the salt tolerance mechanisms of halophytes through elicitors can enhance the production of secondary metabolites, such as phenolics and flavonoids, under saline environment.
