Background: Life style and jobs in current situations have generated increased free radicals such as hydroxyl (OH•) and superoxide (O2•) radicals, thereby increasing stress in humans. Interest in search of antioxidants that trap these free radicals has increased to relieve stress. β-carotene (provitamin A), ascorbic acid (vitamin C), tocopherol or vitamin E, Trolox; butyl hydroxy toluene and phenolic compounds are the well-known antioxidants.

- Altered climate and water stress significantly reduce chilli crop yields, prompting a strategic evaluation of different chilli genotypes for stress tolerance.
- The study examined 20 chilli genotypes under varying water conditions, assessing traits like relative water content, chlorophyll levels, and antioxidant enzyme activity to determine drought resilience.
- Genotypes such as KCa-5, KCa-6, and KCa-10 exhibited strong water stress tolerance, showcasing low oxidative damage and high antioxidant levels, ultimately leading to their classification into three groups based on their drought resilience.
Flavonoids are exploited as antioxidants, antimicrobial, antithrombogenic, antiviral, and antihypercholesterolemic agents. Normally, conventional extraction techniques like soxhlet or shake flask methods provide low yield of flavonoids with structural loss, and thereby, these techniques may be considered as inefficient. In this regard, an attempt was made to optimize the flavonoid extraction using orthogonal design of experiment and subsequent structural elucidation by high-performance liquid chromatography-diode array detector-electron spray ionization/mass spectrometry (HPLC-DAD-ESI/MS) techniques.
