From Phytochemical Screening to School Health Literacy: A Comparative Study of Malachra Capitata Leaf–Flower Extracts and A Guidance-Based Model for Secondary Student Awareness of Antioxidant and Anticancer Science

Abstract

This study integrates two traditionally separate domains—laboratory evaluation of plant-derived bioactivity and school-based educational guidance—by investigating the comparative antioxidant and anticancer potential of Malachra capitata extracts and translating key scientific concepts into an awareness-oriented framework for secondary-level learners. Building on classical documentation of forest minor products as sources of bioactive materials (Brown, 1921), the research first develops a comparative extraction and screening logic for aqueous and ethanolic preparations, emphasizing total phenolic quantification as an interpretable proxy for antioxidant potential (Singleton & Rossi, 1965) and discussing the rationale for in vitro cell-line reasoning in anticancer screening contexts (Niu & Wang, 2015). The biomedical component is positioned within contemporary methodological thinking that connects modeling and screening to iterative drug discovery pipelines, while also acknowledging that models and in vitro systems offer constrained but practically valuable windows into biological response (Carrara et al., 2017; Niu & Wang, 2015). The second component addresses the educational “implication” dimension by proposing a structured guidance-and-counseling delivery model to cultivate student awareness about health-related science, risk interpretation, and evidence-based decision-making in adolescence, drawing on established work about guidance services, student needs, and the effect of counseling interventions on school outcomes and discipline (Ajowi & Enose, 2010; Dash, 2003; Jaiswal, 2002; Jorge, 1968). The integrated findings are presented descriptively: ethanolic extracts are interpreted as the more likely phenolic-rich fraction based on solvent logic used in plant screening contexts (Singleton & Rossi, 1965; Irawan et al., 2021), while aqueous extracts are framed as potentially more acceptable for school demonstrations and safer conceptual translation for youth awareness contexts (Dash, 2003; Naik, 1997). A guidance-based awareness pathway is articulated to support age-appropriate scientific literacy and student self-concept around health learning, aligning with evidence that structured guidance programs can influence academic and psychosocial dimensions (Kamat, 1985; Dandapani, 1977). The study concludes that a comparative “bioactivity-to-awareness” approach can serve as a practical template for secondary education settings when accompanied by ethical, methodologically sound, and student-need-responsive counseling structures (Bhatnagar & Gupta, 1999a, 1999b; Best & Kahn, 2000).
