ABSTRACT
The present study focused on the effect of habitat condition on some biochemical metabolites of Ammi visnaga as commonly recognized medicinal plant. The obtained results indicated significant decrease in the total soluble proteins, total soluble sugars and proline content of A. visnaga collected from clay loamy soil (Zagazig habitat) compared to that collected from that of sandy loam soil (Belbis habitat). The high proline content in the plant under stress conditions (Belbis habitat) may be a positive adaptive mechanism for overcoming the stress conditions. The secondary metabolites increased in A. visnaga collected from clay loamy soil as compared with that collected from that of sandy loam soil. The HPLC analysis of polyphenols revealed highest concentration of gallic acid and the lowest of cinnamic acid in loamy soil. Meanwhile in sandy loam soil the highest concentration was chlorogenic acid and the lowest was vanillin. The GC-MS analysis ethanol extract showed the presence of fatty acids, carbohydrates and other organic compounds in A. visnaga shoot collected from two habitats. The obtained results revealed higher number of organic compounds extracted by ethanol in the plants collected from sandy loam soil (Belbis habitat) than that of clay loam soil (Zagazig habitat). The results also cleared that the highest component of GC-MS of A. visnaga ethanol extract was citric acid.
