The myrrh genus, Commiphora, is the most species rich genus of flowering plants in the frankincense and myrrh family, Burseraceae. Use of myrrh resin is frequent and pronounced throughout historical texts of cultural significance, including the Bible. The objective of the present piece of research work is to green synthesis and characterize the silver nanoparticle from the bark of Commiphora caudata (wight&Arn) Engl. The appearance of dark reddish brown colour was a clear indication of the formation of AgNPs in the reaction mixture; the colloidal entity was subjected to UV spectral, FTIR, FESEM, DLS, XRD and Zeta Potential. FESEM analysis revealed the AgNPs coalesced to nano-clusters predominantly globe-shaped nanocrystals and the images revealed that the sizes were ranged between 8 and 84 d.nm with globular shape with aggregation. The particle size distribution was observed by diffuse light scattering (DLS) method. The distribution of the particles exhibited interesting facts. The large particles were distributed by an intensity of 1.8% and the smallest ones distributed by 93% and the rest by the intermediate particles.FTIR analysis revealed the presence of the functional groups C-H(Amines), C-H(Alcohol), N-H(Primary amines), C-C(Aromatics), C-N(Aromatic amines), C-H(Alkyl-halides), C-N(Aliphatic-amines), C-Cl(Alkyl-halide) and C-H(Alkynes). XRD results revealed that the silver ions reduced to silver oxide in C. caudata are crystalline nature.
