Abstract

The bioactive compounds found in moringa leaves (Moringa oleifera L.) can function as natural antioxidants to protect cells from damaging free radicals. The purpose of this study is to ascertain the antioxidant activity of moringa leaves according to the type of solvent, analyze the relationship between antioxidant capacity and concentration of active compounds, and determine the best solvent. Extraction was carried out using ethanol, methanol, and aquades solvents, followed by testing antioxidant activity using UV-Vis spectrophotometry method on DPPH radicals. The content of phenols, flavonoids, and tannins in the extract was measured to understand their contribution to antioxidant activity Based on the results of the study, the extract containing ethanol solvent showed the most powerful antioxidant activity, with an IC50 value of 103.98 ppm. In conclusion, the type of solvent has a significant effect on the antioxidant activity of moringa leaves, with ethanol solvents being the most effective option. This research strengthens the potential of moringa leaves as a natural source of antioxidants that can be utilized for applications in the pharmaceutical and health fields, although further research is needed to optimize extraction techniques and the development of moringa oleifera leaf-based product

Abstract

Parabens are widely used preservatives in cosmetic products to inhibit microbial growth; however, excessive exposure has been associated with endocrine disruption and skin irritation. This study reviews and compares analytical methods used for the identification and quantification of parabens in cosmetic products, namely Thin Layer Chromatography (TLC), UV–Vis spectrophotometry, and High-Performance Liquid Chromatography (HPLC). Literature searching was conducted through PubMed and Google Scholar for studies published between 2015 and 2025. Ten articles met the inclusion criteria as original research utilizing one of the three analytical methods. TLC is effective for preliminary qualitative identification based on Rf values but is less suitable for quantitative analysis. UV–Vis spectrophotometry allows rapid determination of paraben levels within a λmax range of 254–258 nm and provides reliable results for relatively simple matrices. HPLC generally demonstrates the highest sensitivity, specificity, and accuracy, commonly employing C18 columns, methanol–aquadest mobile phases, retention times of 3–11 minutes, and high linearity (R² ≥ 0.999). Several studies also reported paraben levels exceeding the safety limits established by BPOM RI, highlighting the importance of chromatographic confirmation in cosmetic surveillance. Therefore, the selection of analytical methods should follow a fit-for-purpose approach based on analytical objectives, matrix complexity, and regulatory requirements to ensure product safety.
