Objective: The aim of this study is to analyze the volatile components of the leaves of Aegle marmelos, Psidium guajava, and seeds of Nigella sativa, using gas chromatography-mass spectrometric (GC-MS) and correlate with their in vitro antioxidant activity. Materials and Methods: Plant material was analyzed for heavy metal content (HMC), pesticide residue (PR), and the presence of microbes/fungi. Following hydrodistillation, the volatile components (AM, PG, and NS) were subjected to GC-MS analysis and in vitro antioxidant assay (2,2-diphenyl-1-picrylhydrazyl). Results: The plant material passed the test for HMC, PR, microbial, and fungal contamination. Using GC-MS, the number of compounds identified in AM, PG, and NS were 62, 46, and 58, respectively. The antioxidant activity of AM, PG, and NS was 98.538%, 98.955%, and 97.755%, respectively. Conclusion: GC-MS-based methods can be successfully utilized for phytochemical profiling and standardization of plant material. Abbreviations Used: AM: Volatile oil of Aegle marmelos Correa.; GC-MS: Gas chromatography-mass spectrometry; HMC: Heavy metal content; NS: Volatile oil of Nigella sativa Linn.; PG: Volatile oil of Psidium guajava Linn.; PR: Pesticide residue.
