Abstract

Oxidative stress is a major driver of degenerative diseases, while synthetic antioxidants may pose long-term safety risks. The need for safer natural antioxidants has accelerated the exploration of medicinal plants, which are rich in bioactive compounds with antioxidant potential, particularly flavonoids and polyphenols. This systematic review aimed to classify antioxidant compounds from medicinal plants according to their phytochemical groups and to appraise their therapeutic potential based on recent pharmacological evidence. Articles published between 2015 and 2025 were retrieved from PubMed, Google Scholar, Garuda. Fifteen studies met the inclusion criteria for antioxidant activity testing. The review identified dominant antioxidant constituents, classified by chemical structure, including phenols, polyphenols, flavonoids, quercetin, and flavonoid–hydroquinone derivatives, reported across multiple plant species (Table 1). Plants consistently described as antioxidant sources were reundeu (Straurogyne elongata), moringa (Moringa oleifera), Indonesian bay leaf (Eugenia polyantha), water clover (Marsilea crenata), mango leaves (Mangifera indica), raru wood (Cotylelobium lanceolatum), and Jamaican cherry (Muntingia calabura), exhibiting moderate to strong antioxidant activity mainly in DPPH and FRAP assays. Overall, the findings indicate that antioxidant activity correlates with structural features such as the number and position of hydroxyl (–OH) groups, conjugated systems, and metal-chelating capacity. However, these compounds still face challenges related to poor stability and low bioavailability, suggesting that nanotechnology-based delivery systems may enhance formulation effectiveness. In conclusion, the plants reviewed contain promising antioxidant constituents, with quercetin and flavonoids emerging as the most active compounds, supporting their development as candidates for natural antioxidant-based phytopharmaceutical raw materials in Indonesia.

Abstract

The genus Cyperus is widely recognized as decorative flora. Empirically, Cyperus plants have been utilized to treat wounds, inflammation, and digestive disorders. While the genus is reported to exhibit antioxidant properties, scientific data regarding Cyperus involucratus remains limited. This research aimed to identify antioxidant compounds in C. involucratus using Ultra-High-Performance Liquid Chromatography-High Resolution Mass Spectrometry (UHPLC-HRMS). The C. involucratus methanolic extract was obtained through maceration using a 70% methanol solvent. Separation was performed using a UHPLC gradient system with a flow rate of 0.3 mL/min , while compound identification was conducted using a Quadrupole-Orbitrap MS detector in positive mode. The radical scavenging activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The analysis identified 175 metabolites within the methanolic extract. Based on mzCloud library matching with confidence scores of 97.4–100%, 12 primary bioactive compounds were identified: oleamide, α -linolenic acid, kaempferol, scutellarin, hexadecanamide, 1-linoleoyl glycerol, 1-stearoy-rac-lglycerol, adenine, adenosine, L-tyrosine, stearamide and nootkatone. The extract possessed a moderate radical scavenger with an IC50 value of 57.94 μg/mL. These findings provide a scientific foundation for further investigation of C. involucratus as a potential natural antioxidant, although further in vivo studies are required to validate its broader pharmacological outcomes.

Abstract

Cat's whiskers (Orthosiphon stamineus Benth.) is an herbal plant known for its significant antioxidant activity, making it a valuable resource in traditional medicine. This study aims to investigate the effects of different drying temperatures and durations on the antioxidant activity of cat's whiskers using the DPPH (2,2-diphenyl-1-picrylhydrazyl) reagent. The research was conducted through a systematic analysis of drying temperatures of 40, 50, and 60°C over 1, 2, and 3 days, to establish a correlation between drying parameters and antioxidant activity. Statistical analysis using two-way ANOVA revealed that drying conditions significantly influenced antioxidant activity, whereas water content remained stable across all treatments. Based on the results, the optimal drying condition is 60°C for 1 day, which exhibited the highest antioxidant activity, with an IC50 of 13.62 μg/mL and a water content of 3.69%. This study advances scientific knowledge, particularly regarding the most effective drying methods for cat's whiskers to preserve the stability of the plant's bioactive compounds. Ultimately, these findings provide a scientific basis for developing standardized drying protocols to maximize the therapeutic benefits of cat's whiskers in health applications.
