ELEMENTAL ANALYSIS, DITERMINATION OF ALKALOID, SAPONIN AND FLAVONOID OF THREE SELECTED SPECIES OF ZINZIBERACEAE FAMILY

The present study reveals the chemical composition and mineral analysis of Curcuma amada, Alpinia nigra, Amomum gracile. They are belongs to the same family zingiberaceae. The result reveals; (a) alkaloid contains in Alpinia nigra (6.0mg/100gm), amomum gracile (0.6mg/100gm), Curcuma amada (4.280mg/100gm); (b) saponin contain in Alpinia nigra burtt(18.960mg/100gm), Amomum gracile (18.1mg/100gm) and Curcuma amada (21.22mg/100gm); (c) flavonoid contains in Alpinia nigra burtt  (14.160gm/100gm), Amomum gracile (9.220mg/100gm) and Curcuma amada (8.400mg/100gm). The result of elemental analysis measure in ppb reveals; Alpinia nigra burtt contains iron (1.007 ± 0.001), Zn (0.408 ± 0.001), Cu (2.27 ± 0.08), Mo (0.011 ± 0.006), Cr (2.151 ± 0.0307) and Mn (0.013 ± 0.002), Amomum gracile was found to contains Fe (0.971 ± 0.046), Zn (0.414 ± 0.083), Cu (1.70 ± 0.03), Mo (0.013±0.004), Cr (5.091 ± 0.011) and Mn (0.015 ± 0.003) and Curcuma amada was found to contains Fe (0.954 ± 0.003), Zn (0.1764 ± 0. 0.005), Cu (1.80± 0.02), Mo (0.016 ± 0.008), Cr (1.643 ± 0.001) and Mn (0.014 ± 0.002) respectively. Vanadium cannot be detectable in all the three selected plant species for the study
