Abstract

Arabica coffee (Coffea arabica) contains various bioactive compounds such as caffeine, polyphenols, flavonoids, and alkaloids that have the potential to produce diverse pharmacological effects on both the autonomic and central nervous systems. The variation in its chemical composition is influenced by factors such as cultivar, post-harvest processing, and preparation methods, resulting in biological responses that are dose-dependent and not always linear. This study aimed to evaluate the pharmacological activity of arabica coffee simplicia powder at three concentrations (1%, 2%, and 4%) by observing parasympathomimetic, parasympatholytic, sympathomimetic, sympatholytic, analeptic, central nervous system stimulation and depression, as well as muscle relaxation parameters. The research was conducted using a laboratory experimental design with test animals administered orally according to the designated concentrations. The results showed that some parameters increased at higher concentrations, such as parasympathomimetic activity (51.85%) and central nervous system stimulation (63.74%), while other parameters demonstrated decreasing or biphasic patterns, such as sympatholytic activity, which was high at 1% and 4% but low at 2%, and analeptic activity, which dropped sharply at 2% and increased again at 4%. These response patterns align with literature indicating that caffeine and polyphenols such as chlorogenic acid may interact synergistically or antagonistically, generating complex pharmacological effects through mechanisms involving adenosine modulation, excitatory neurotransmitters, the enteric nervous system, as well as antioxidant and anti-inflammatory pathways. Overall, this study demonstrates that arabica coffee simplicia exhibits multipotential pharmacological activity, with responses strongly influenced by concentration and the composition of its bioactive compounds, thereby providing a basis for further research on the phytopharmaceutical potential of arabica coffee.

Abstract

Samanea saman (Jacq.) Merr. leaves contain various secondary metabolites with potential biological activities; therefore, preliminary toxicity testing is necessary to evaluate their safety and bioactive potential. This study aimed to determine the Lethal Concentration 50 (LC₅₀) value of the 80% ethanol extract of Samanea saman leaves using probit analysis and to classify its toxicity level. An experimental study was conducted using the Brine Shrimp Lethality Test (BSLT) with Artemia salina Leach larvae as the test organism. The extract was tested at concentrations of 10, 100, 500, 1,000, and 5,000 ppm. Larval mortality was recorded after the incubation period, and the data were analyzed using probit analysis to determine the LC₅₀ value. The results showed that larval mortality increased with increasing extract concentration, reaching 18.42%, 23.33%, 45.83%, 70.83%, and 88.89%, respectively. Probit analysis revealed an LC₅₀ value of 301.72 mg/L (ppm). Based on the toxicity classification, this value falls into the moderately toxic category, indicating that the 80% ethanol extract of Samanea saman leaves exhibits toxic activity against Artemia salina larvae. These findings suggest that the extract has promising potential as a source of bioactive compounds and warrants further investigation, including the isolation and identification of active constituents, cytotoxicity evaluation, and safety assessment in more complex biological systems.
