Abstract: Ganoderma lucidum (Lingzhi) and Aloe vera are traditional Chinese medicinal materials extensively documented in classical pharmacopeias such as Compendium of Materia Medica for their therapeutic properties. However, discussions on their trace element profiles and pharmacological mechanisms remain limited. This study employs flame atomic absorption spectrometry (FAAS) to analyze inorganic constituents in traditional Chinese medicine. Aligned with the pedagogical features of instrumental analysis experiments, we developed a problem-oriented teaching model for undergraduates to advance innovative experimental reforms. This approach enhances students' practical competence and innovative thinking while reinforcing their cultural affinity for traditional medicine practices.
