<p>This study provides a comprehensive analysis of bioactive compounds in two bryophyte species, <i>Plagiochasma appendiculatum</i> and <i>Plagiomnium cuspidatum</i>. The plant specimens were meticulously collected from Artola, Uttarakhand, India, and subjected to a detailed phytochemical investigation. Compound extraction was performed using the Soxhlet extraction method, followed by thorough chemical analysis utilizing advanced chromatographic techniques. Thin-Layer Chromatography (TLC) and High-Performance Liquid Chromatography (HPLC) were employed to isolate and identify secondary metabolites. The chromatographic analyses revealed the presence of significant quantities of flavonoids, phenols, and terpenoids in the methanolic extracts, suggesting their potential as bioactive components. To further elucidate the chemical structures of these compounds, sophisticated analytical techniques, including Fourier Transform Infrared (FT-IR) Spectroscopy and Nuclear Magnetic Resonance (NMR), were utilized. FT-IR provided insights into the functional groups present, while NMR confirmed the presence of key bioactive substances such as caffeic acid, quercetin, and benzoic acid. These phenolic compounds are noted for their diverse biological activities, including antioxidant, antimicrobial, and antifungal properties. Their potential applications in medicine and sustainable agriculture underscore their value as natural remedies and contribute to the development of eco-friendly agricultural practices. This research significantly advances our understanding of the chemical composition and potential bioactive properties of <i>Plagiochasma appendiculatum</i> and <i>Plagiomnium cuspidatum</i>, highlighting their significance in both scientific and practical contexts.</p>
