Data confidence 85 high
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Salsola kali L., a halophytic plant renowned for its resilience in arid and saline environments, possesses a rich and diverse phytochemical profile with significant bioactive potential. This study provides a comprehensive phytochemical and pharmacological evaluation of S. kali extracts, employing an integrative analytical approach combining gas chromatography‐mass spectrometry (GC‐MS), inductively coupled plasma‐optical emission spectrometry (ICP‐OES), and high‐performance liquid chromatography‐diode array detection (HPLC‐DAD). The phenolic composition of the methanolic extract revealed 17 identified compounds, with quercetin 3‐O‐β‐galactoside (14.74 mg/g extract) and pyrocatechol (14.54 mg/g extract) being the most abundant, followed by other notable compounds highlighting the plant’s phenolic diversity. Furthermore, bioavailability and pharmacokinetic properties of the identified bioactive compounds were predicted using SwissADME and pkCSM tools, revealing favorable drug‐like characteristics. GC‐FID analysis revealed that the hexane extract primarily contained saturated fatty acids, with palmitic acid being the most abundant, comprising 55.17% of total fatty acids. The mineral content analysis revealed a rich profile of essential macro‐ and micronutrients, with potassium (2.62%) as major constituents, alongside high levels of iron (379.82 mg/L). Pharmacological assessments demonstrated significant antioxidant activity, with the methanol extract showing moderate DPPH radical scavenging activity (IC 50 = 90.85 ± 0.91 μg/mL), while the hexane extract exhibited lower activity (IC 50 = 542.59 ± 2.68 μg/mL). The methanol extract also displayed promising enzyme inhibitory effects, with moderate activity against butyrylcholinesterase (BChE) and notable inhibition of α ‐glucosidase. However, acetylcholinesterase (AChE) inhibition was not observed at concentrations below 200 μg/mL. This study elucidates the structural and functional attributes of S. kali metabolites, emphasizing their potential as antioxidants, enzyme inhibitors, and nutrient sources for therapeutic use.
