Areca nut is a widely cultivated crop in south India. It is the livelihood of the most of the south Indian farmers. It is used recreationally and also has medicinal applications. There are twenty species 1 . There is significant variation in size and hardness of these areca nuts. These nuts produce tightness in throat 2 . The varieties of areca nut are dependent on locality, soil and climate. These plants suffer from two major fungal diseases. The Kole Roga (fruit rot / bud rot) and Anabe Roga (foot rot). Ten different varieties of areca grown in south India have been characterised using X-Ray Diffraction (XRD), Energy Dispersive X-Ray Analysis (EDAX), Fourier Transform Infrared spectroscopy (FTIR), Raman Spectroscopy, Scanning Electron Microscope (SEM) and Xplore AC magnetic techniques to understand the physical properties of the samples which have wide applications in various medicinal and a few daily routines. It was observed that among these areca samples, Jini and Saraku areca nuts have a exceptional behavior in terms of the physical parameters. These samples stand unique in terms of unit cell volume, crystallite size volume, elemental distribution and magnetic properties. The dielectric constant has been computed using XRD data. Correlation among different varieties of areca nut and their corresponding physical parameters was conducted using stochastic process.
