A study has been undertaken to study the variability in mineral contents in areca samples collected from different districts of the Karnataka. The Nutrients were estimated using inductively coupled plasma optical emission spectrophotometer (ICPOES). The difference in elemental contents was highly significant. The higher mineral content of phosphorous (0.30 %), magnesium (0.09 %) and iron (231 ppm) was recorded in areca samples of Hosdurga taluk of Chitradurga district but these samples were lower in copper (5.2 ppm). Koppa, N. R. Pura, Tarikere taluks Chikkamagulur district contained higher calcium (0.10 %) whereas it was lower in Kadaba of DK (0.05 %). The samples of different taluks: Harihar (K 0.47 %), Shikaripura (Zn 27 ppm), N. R. Pura (Cu 25 ppm) and Mudigere (B 278 ppm) contained significantly higher mineral contents. The variation in the mineral nutrients might be due to soil conditions, management practices, processing technique and environmental factors. The present study is imminent. Since the major portion of areca is used for human consumption. Further, it has been inferred that, considering the concentration of these minerals limit of areca for human consumption might be 166 g per day per person and it varies with the change in mineral contents in areca samples.
