Phytochmical constituents and nutrient evaluation of Zingiber officinale

Abstract

Zingiber officinale has been analyzed for the main phytochemical composition, nutrient and mineral composition.The phytochemical screening of chemical constituents of the plant showed that ginger contains sterols , flavonoids, glycosides amino acids , carbohydrates , taninat terpenoids ,saponins.

The quantitative contents of flavonoids, sterols, phenolic compounds, and tannin were (45.3 ± 1.527, 18.033±0.233, 7.241 ± 1.076, 4.21 ±1.042) mg / 100 g respectively while the moisture contents of paln ginger (9 ± 1.41%), and (90± 1.41%) for the total solids. Values crude fiber and ash were estimated and found to be  (0.66 ± 0.2%), and (13.5%) were. Crude fat content of ginger was(4.2±0.2%) and (14.69 g / 100gm) protein and (92±2.12 mg/100gm) for carbohydrates , the energy value was (459.56) Kcal.100g^-1 .The predominant  minerals were potassium10245µg.g^-1, followed by sodium385 µg.g^-1, calcium351 µg.g^-1, iron122 µg.g^-1, zinc45.9 µg.g^-1, manganese6.24 µg.g^-1, selenium 0.189 µg.g^-1, copper 0.12 µg.g^-1, coblt 0.05 µg.g^-1, cadmium 0.002 µg.g^-1 add ginger to contain vitamins such as A, E and concentrations in the order (29.70) mg.cm ^-3, (83.66) mg.cm^-3. and (35.75)mg.100cm^-3 from vit .
