Objective: Nano-chemistry is an emerging field with its presence felt in every sphere of life. The synthesis of nanoparticles using plant extract is alternative to the conventional methods with deleterious effects on the environment. Materials and methods: The different antioxidants present in plant extract act as reducing and stabilising agent for the synthesis of Bursera serrata conjugated gold nanoparticles (BS-AuNPs). The fruits of B. serrata were well-characterized for its nutritive potential, mineral content and antioxidant properties in different solvent extracts. The quantitation’s of polyphenolics in the fruits were carried out by High Performance Liquid Chromatography (HPLC) method which indicated the presence of phenolics and polyphenolics in different amounts.  The phytochemicals present in the fruits extract   were utilized for the one-step green synthesis method of B. serrata conjugated AuNPs (BS-AuNPs). Results: The formation of BS-AuNPs was confirmed by Surface Plasmon Resonance spectroscopy (SPR), high resolution transmission electron microscopy (HRTEM), and X-ray diffraction (XRD) analyses. Conclusion: The BS-AuNPs obtained by these biogenic syntheses have potential biological and medical applications depending on their size and aqueous stability.
