is a medicinal plant from the Lamiaceae family whose biological potential remains poorly explored. The aim of this study was to comprehensively assess the pol-yphenol profile, macro- and microelement composition, and the antioxidant, an-ti-diabetic, and anti-obesity activities of various plant organs (leaves, flowers, stems, and roots). The leaves and flowers exhibited the highest concentration of phenolic compounds, while anthocyanins were detected exclusively in the flowers (215.05 mg/100 g dry matter (dm)) and constituted 3% of the total polyphenols. Verbas-coside and chlorogenic acid were the most abundant polyphenols, reaching 4618.88 and 3277.83 mg/ 100 g dm in the leaves. The highest ABTS and FRAP scavenging activity was observed in leaves (19.30 and 7.62 mmol TE/g dm, respectively). Principal component analysis demonstrated a strong correlation between polyphenol content and antioxidant activity (ABTS-r= 0.87 and FRAP-r = 0.90), which was further confirmed by Pearson's correlation coefficients. The study also highlighted the significant impact of mineral composition on biological activity-calcium and magnesium dominated in stems (10,100 and 3900 mg/kg) and in roots (9200 and 3100 mg/kg), supporting the functioning of an-tioxidant enzymes, while zinc and manganese in leaves (89.43 and 155.33 mg/kg) con-tributed to intense metabolic processes. could serve as a valuable source of natural antioxidants and enzyme inhibitors associated with glucose and lipid metabolism, suggesting its promising application in the prevention and management of metabolic disorders..

Developing a practical strategy to enhance the quality of medicinal herb while alleviating negative plant-soil feedback (NPSF) is critical for agriculture. In this study, we investigated the effects of selenium nanoparticles (SeNPs) on Panax notoginseng through a two-year field experiment. Four treatments were established: a control (SeNPs_0) and three SeNPs concentrations (3, 5, and 10 mg/L), which were foliar-sprayed every 15 days for a total of six applications.

Background: Classification of rose species and verities is a challenging task. Rose is used worldwide for various applications, including but not restricted to skincare, medicine, cosmetics, and fragrance. This study explores the potential of Laser-Induced Breakdown Spectroscopy (LIBS) for species and variety classification of rose flowers, leveraging its advantages such as minimal sample preparation, real-time analysis, and remote sensing.

Flowering is a key trait in most crops and may depend on cold exposure, a process known as vernalization, but the underlying regulatory mechanisms are poorly understood. Taraxacum koksaghyz is a rubber-producing dandelion of the family Asteraceae, which also includes other economically important crops such as chicory and lettuce. Most T.
