Introduction: Hedychium coronarium J. König, from the Zingiberaceae family, is a rhizomatous herb used in Ayurvedic medicine for its febrifuge, anti-rheumatic, and anthelmintic properties.
Method: This study characterizes the chemical diversity and biological activities of H. coronarium oleoresins collected from four locations in Uttarakhand: Pantnagar (HCPNOR), Bageshwar (HCBOR), Nainital (HCNOR) and Pithoragarh (HCPOR). GC-MS analysis identified key constituents, including n-Hexadecanoic acid (8.3-9.8%), photocitral B (4.8- 27.6%), (Z)-9- eicosenoic acid (0.7-6.5%), α-pinene (2.5-3.5%) and trans-13-octadecenoic acid (7.5%). Heat map clustering, Venn diagrams, and PCA revealed compositional variations.
Result: The oleoresins showed potent nematicidal, insecticidal, herbicidal, and antifungal activities against Meloidogyne incognita, Spodoptera litura, Raphanus raphanistrum subsp. sativus, Fusarium oxysporum, and Curvularia lunata.
Conclusion: These findings highlight the potential of H. coronarium oleoresins for pest and pathogen management, with chemical variation driven by environmental factors.
Keywords: Hedychium coronarium; biological activities.; oleoresins; α-pinene.
