Background: The utilization of coffee cascara, a byproduct of coffee cultivation, in cancer therapy research. This research begins with the rationale of exploring medicinal plants, especially coffee, to obtain compounds that can target cancer cells with fewer side effects. Objectivity: This research aims to extract and evaluate the secondary metabolites from robusta coffee cascara, such as friedelin, lupeol, stigmasterol, ursolic acid, caffeine, chlorogenic acid, caffeic acid, and catechin, for their cytotoxic activity against Hela and MCF-7 cells. The aim of this research is also to identify and understand the cytotoxic mechanisms of compounds like stigmasterol, which showed significant cytotoxicity against cancer cells, paving the way for developing targeted cancer therapies from natural sources. Methods: Robusta coffee cascara then goes to the process of extraction using ethanol, fractionation, isolation, purification, and characterization, followed by bioactivity evaluation using in vitro method through breast cancer cell line MCF-7 and cervical cancer cell line HeLa and determination of active compound levels. Results: The cascara, a byproduct of coffee cultivation, is rich in proteins, polysaccharides, and bioactive compounds. Through extraction and purification processes, eight compounds were isolated and characterized, including (1) friedelin, (2) lupeol, (3) Stigmasterol, (4) Ursolic acid, (5) caffeine, (6) Chlorogenic acid, (7) caffeic acid, and (8) catechin. Bioactivity evaluation shows that stigmasterol (3) is the most cytotoxic compound with a value against Hela cells with an IC50 value of 25.85 μg/mL in the toxic category and against MCF-7 cells with an IC50 value of 12.83 μg/mL in the very toxic category. The results of determining the levels of active compounds in robusta coffee cascara extract showed that friedelin (1) 0.539{\textpm}0.137\%; lupeol (2) levels were 0.087{\textpm}0.015\%; (3) stigmasterol 0.126{\textpm}0.046\%; ursolic acid (4) 0.627{\textpm}0.002\%; caffeine (5) 3,203{\textpm}0.069\%; chlorogenic acid (6) 0.679{\textpm}0.003\%; caffeic acid (7) 0.153{\textpm}0.003\% and catechin (8) 0.3590.012\% mg/g extract. Conclusion: The research on robusta coffee cascara extract as a potential source of anticancer compounds.

Background: NADES is an alternative solvent in the extraction of metabolites from plants which has many environmental benefits, such as low toxicity, biodegradability, can dissolve polar and non-polar compounds, low costs and simple preparation. Objective: This study aims to determine the effect of natural deep eutectic solvent-based ultrasonic-assisted extraction (NADES-UAE) on enrichment of caffeine and chlorogenic acid in extract from green coffee beans (Coffea canephora). Methods: The powders were extracted using NADES-UAE method in several types of extraction condition, including the composition of NADES, water addition in NADES and extraction time. Caffeine and chlorogenic acid content were analyzed using HPLC, reverse phase system and C18 ODS-3 column. Results: The highest of caffeine and chlorogenic acid content was respectively, 7.89 mg/g and 28.62 mg/g (composition of NADES betaine: sorbitol [1:1.2] ratio and NADES-water addition [1:2] ratio for 30 min). Conclusion: This research showed that the composition of NADES, extraction time and water addition are important parameter in extracting caffeine and chlorogenic acid content in green coffee beans.
