Abstract
In this research, nanocellulose is isolated from Moringa oleifera seed using acid hydrolysis and the structural properties were determined. X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy were used for the characterization of the isolated nanocellulose. The most noticeable peak is observed at and the value of the crystallinity index () from the XRD pattern is 63.1%. The calculated values of hydrogen bond intensity (HBI), lateral order index (LOI) and total crystalline index (TCI) are 0.93, 1.17and 0.94 respectively exhibited high degree of crystallinity and well arranged cellulose crystal structure. The isolated nanocellulose has an average length and diameter of 14.3 and 36.33 respectively. Furthermore, the FTIR peaks revealed the presence of C-H bending, C-O stretching and O-H stretching functional groups.

Summary
Nanocellulose is isolated from Moringa oleifera seed using acid hydrolysis and the structural properties were determined. Moringa oleifera is a plant material composed of organic nutrients, lignin, hemicellulose and cellulose. Chemical method material can change in crystal arrangement (crystal structure), degree of crystallinity, morphology and surface chemistry [7]. Nanocellulose is isolated using various distinct approaches such as oxidative, acid hydrolysis, oxidative, enzymatic and mechanical treatments of cellulose. The most common approach for isolating nanocellulose from wood and other plant materials is acid hydrolysis [8,9]. The potential and industrial application of the isolated nanocellulose is based on the structural and other properties of the nanocellulose. The aim of this research is to synthesis, characterize and determine the structural properties of nanocellulose from moringa oleifera seed
