Article Abstract
The purpose of this study is to check the effectiveness of the analysis method that separates and quantifies β-caryophyllene among clove extracts and validate according to current ICH guidelines. The β-caryophyllene was active constituent of clove buds. The developed method gave a good detection response. In the specificity test, the standard solution was detected at about 17.32 min, and the test solution was detected at 17.32 min. The linearity of β-caryophyllen was confirmed, and at this time, the correlation coefficient (R) of the calibration curve showed a high linearity of 0.999 or more in the concentration range. The levels of LOD and LOQ were 1.28 ug/mL and 3.89 ug/mL, respectively. The accuracy was confirmed to be 101.6-102.2% and RSD 0.95 ~ 1.31%. As a result of checking the repeatability and inter-tester reproducibility to confirm the precision, the RSD was found to be 1.34 ~ 2.69%. This validated GC method was successfully applied to a soft capsule containing clove extract and other materials for clinical trials. Therefore, this method can be used as an analytical tool for quality control of various samples, including clove extracts and their products of food and pharmaceutical uses.

Aims: Type 2 diabetes (T2D) related cognitive impairment links to comorbid and modifiable olfactory dysfunction; however, the efficacy of olfactory training (OT) to mitigate cognitive decline specifically in these patients with mild cognitive impairment (MCI) remains unestablished. This study aimed to determine whether OT alleviates cognitive decline in this population.
Materials And Methods: In this 16-week, open-label trial, 60 T2D participants with MCI were randomly assigned (1:1) to OT or routine care (control).

The worldwide occurrence of neurodegenerative diseases in Alzheimer's and Parkinson's patients is increasing owing to multiple disease mechanisms, including oxidative stress, neuroinflammation, mitochondrial dysfunction, and excitotoxicity. (clove) flavonoid metabolites show strong neuroprotective potential because they act as antioxidants, reduce inflammation and lipid peroxidation, and prevent apoptosis. The key flavonoid metabolites, quercetin, kaempferol, kumatakenin, myricetin, ombuin 3-O-β-d-glucopyranoside, and tamarixetin 3-O-β-d-glucopyranoside, bind to various brain receptors implicated in disease propagation pathways and induce changes that support neuronal survival and decrease cognitive impairment.

Antimicrobial resistance (AMR) poses a serious global health threat, reducing the efficacy of existing treatments due to the emergence of resistant strains such as ESBL-producing bacteria and drug-resistant fungi. This study investigates the antibacterial, antifungal, and antioxidant properties of five medicinal herbs-Vala, Manjistha, Clove, Sandalwood, and Cinnamon-and their polyherbal blend. The alcoholic extract of the blend showed notable antibacterial activity, with a maximum inhibition zone of 4 mm.
