“…Based on the chemical structure, paracetamol, and caffeine contain the UV chromophore, so these analyts can be detected by UV. Previous studies were reported paracetamol in herbs powder spectrophotometry (Sari, et al, 2021), FT-IR (Wahyuningsih, et al, 2022), highperformance liquid chromatography (HPLC) (Laksmi, et al, 2016;Wisnuwardani, et al, 2018;Mamat, et al Sari, et al, 2021), high-performance thin layer chromatography (HPTC) (Mahesh, et al, 2011;Prawez, et al, 2022), LC/MS/MS (Delahaye, et al, 2021). However, a simple, fast, selective, and inexpensive method for routine analysis is still preferred.…”
