Abstract

Chisocheton is a large source of limonoids with various pharmacological effects, such as antiviral, antibacterial, antimalarial, antifungal, and cytotoxic activities. This study aimed to isolate, elucidate, and evaluate the cytotoxicity of limonoids from C. pentandrus stembarks. Isolation was carried out using various separation methods including extraction and column chromatography. Spectral data were analyzed by FT-IR, UV, DEPT 135°, 1H, 13C-NMR, and HRTOF-MS and compared with those previously reported to determine the chemical structure.The obtained limonoids were lasiocarpine (1), lasiocarpine B (2), pentandricine (3), and 16β-hydroxydysobinin (4); all of which were successfully isolated from C. pentandrus for the first time. The cytotoxic activity of these limonoids were also evaluated against Michigan Cancer Foundation-7 (MCF-7) breast cancer cells using PrestoBlue method. Lasiocarpine A revealed the strongest cytotoxicity with an IC50 of 42.62 µM in moderate level.

Abstract

Naphthalene derivative compounds named Eleutherol (1) and Eleutherol C (2) have been isolated from Bawang Tiwai Bulb Eleutherine bulbosa. We tested its cytotoxic activity against T47D breast cancer cells in vitro after isolating compounds 1 and 2 from the EtOH extract using conventional chromatography methods. Their chemical structures were elucidated based on spectroscopic analysis, including IR, HR-TOFMS, 1D, and 2D NMR, and by comparison to those related spectra previously reported. Compounds 1 and 2 were tested for their cytotoxic effects against T47D breast cancer cells and showed moderate cytotoxicity against T47D breast cancer cells with IC50 values of 117.15 and 80.21 µM, respectively, compared with cisplatin 24.07 µM.

Abstract

This study evaluates the viability of a problem-based learning (PBL) e-module on elements, compounds, and mixtures through validation by experts and feedback from both teachers and students. This study adopted a research and development (RD) methodology guided by the ADDIE framework. The participants consisted of teachers and students from SMPN 10 Pontianak. The data were gathered using an indirect communication method, specifically through feasibility assessment sheets and questionnaires filled out by both teachers and students. The results indicated that the e-module was considered highly suitable for use. The validity coefficient were 1.00 from graphic design experts (categorized as very good), 0.83 from linguists (very good), and 1.00 from subject matter experts (very good). The average coefficient from experts validation was 0.94, which fall into the very good category. In addition, teacher and student responses also indicated very good results: for the media aspect, each response rates were 92% and 85%; for the content aspect, 85% and 83%; and for usefulness, 86% and 85%. These results suggest that the PBL-based teaching e-module is suitable and ready to be used in learning activities

Abstract

The chalcone compound is a precursor of flavonoid and pyrazoline compounds. Chalcone has two aromatic rings (A and B) and one ?,?-unsaturated carbon atom. Chalcone compounds can be synthesized via the Claisen Schmidt condensation reaction. Chalcone synthesis uses the basic ingredients of alpha tetralone and benzaldehyde analogues. In this research, chalcone synthesis took place for 48 hours at room temperature. Synthetic materials using ethanol solvent and sodium hydroxide catalyst, as well as basic ingredients alpha tetralone, 3,4-dimethoxybenzaldehyde and 4-methoxybenzaldehyde. Characterization of synthesized compounds using spectroscopic methods, including 1H-NMR, 13C-NMR, Fourier Transform Infrared (FTIR) and mass spectroscopy. Characterization results using spectroscopic methods showed that the two chalcone analogue compounds were successfully synthesized with yields above 70%. Both chalcone compounds showed low activity against MCF-7 cancer cells. Molecular docking simulations showed that both chalcone analogues produced energy levels and intramolecular interactions that were no better than 4-hydroxytamoxifen.

Abstract

Education plays a vital role in promoting students’ academic success, particularly in subjects that involve abstract and complex concepts such as reaction rates in chemistry. These concepts integrate macroscopic, microscopic, and symbolic aspects, which often lead to misconceptions when not properly understood. Therefore, students’ learning engagement encompassing behavioral, emotional, and cognitive dimensions is essential to foster meaningful understanding. This study aims to analyze the learning engagement of eleventh-grade students in the reaction rate topic at Integrated Islamic Senior High School Al-Mumtaz Pontianak during classroom learning activities. A descriptive qualitative approach was employed involving 18 students enrolled in the chemistry specialization for the 2024/2025 academic year. Data were collected through observation, interviews, and documentation. The findings reveal varied levels of engagement across the three dimensions. Behaviorally, students demonstrated active participation in academic tasks, although attendance consistency and adherence to classroom rules require improvement. Emotionally, students expressed enjoyment during the learning process, yet their specific interest in the reaction rate topic remains limited. Cognitively, students exhibited high motivation and initiative, particularly in collaborative learning contexts and through the use of diverse learning resources and strategies to enhance conceptual understanding. These findings emphasize the need to cultivate balanced engagement across behavioral, emotional, and cognitive domains to strengthen students’ conceptual mastery in chemistry learning.

Abstract

Kleinhovia hospita is a hepatoprotective plant rich in bioactive saponins, yet conventional extraction methods remain inefficient. This study aimed to optimize saponin recovery by comparing Microwave-Assisted Extraction (MAE) against conventional maceration and assessing the effect of solvent polarity. Saponins were extracted using MAE (15 minutes) and maceration (72 h) with various ethanol concentrations ranging from 0 to 96%. Total Saponin Content (TSC) was quantified colorimetrically using the vanillin-sulfuric acid method. MAE significantly outperformed maceration, attaining a two-fold increase in saponin purity (106.67 and 52.92 mg Diosgenin Equivalent (DE)/g extract, respectively) in a fraction of the time. Solvent analysis revealed a trade-off: whereas 96% ethanol yielded the highest specific purity (133.89 mg DE/g), it resulted in low mass recovery. In contrast, 50% ethanol extracted the highest Total Saponin Yield (TSY) (18.84 mg/g powder), effectively balancing matrix swelling with solubility. MAE utilizing 50% ethanol is identified as the optimal, rapid, and green strategy for the industrial production of standardized K. hospita extracts.
