Researchers have discovered that red and green scotch peppers are extremely rich in phytochemicals and that these secondary metabolites are connected to several biological processes in the human body. This study aimed to determine the numerous phytochemicals present in scotch pepper seeds, flesh, and red and green varieties. The samples were pulverized after being air-dried. The phytochemicals and ascorbic acid contents were examined using a High-performance Liquid Chromatography-Ultraviolet detector (HPLC-UV). Twelve phytochemicals and ascorbic acid were identified in the flesh and seed of red scotch pepper, with lycopene having the highest content (83.10 mg/kg), the ascorbic acid content of 8.80 mg/kg; moreover, the seed of red scotch pepper revealed twelve phytochemicals and lycopene being the highest content (75.60 mg/kg) and ascorbic acid content of 6.80 mg/kg, furthermore, fourteen phytochemicals were identified in the flesh of red scotch bonnet pepper with lycopene the highest quantity (86.00 mg/kg) and ascorbic content of 10.60 mg/kg. Twelve phytochemicals were identified in the flesh and seed of green scotch bonnet pepper, lycopene (68.70 mg/kg) being the highest content, ascorbic acid content (6.50 mg/kg), twelve phytochemicals were revealed in the flesh of green pepper and lycopene had highest quantity (76.30 mg/kg), in the seed of green pepper, the lycopene content was 68.70 mg/kg. However, it has been shown that capsaicin, dihydrocapsaicin, and lutein concentrations varied, with red scotch pepper flesh having the highest concentration of capsaicin (7.50 mg/kg). The lycopene and ascorbic acid contents of flesh were the highest (86.00 mg/kg) and (10.60 mg/kg). The study's findings showed that red pepper flesh was better than other components that were looked at.
