| Abstract | ||||
| Plants are potentially useful sources of aromatic, phenolic, antimicrobial and antioxidants compounds. The total aromatic contents, phenolic compounds and antioxidant activities of extracts from four aromatic plants (Cinnamomum zeylan blume, Eiettaria Cardamorum motan, Citrus Aurantium l and Galanga Galangal Alpinia officinarum) have been determined. Antibacterial activity was assayed against a variety of human pathogenic bacteria (Escherichia coli, Bacillus subtillus and Altеrnaria tenuis) and antifungal activity was assayed against Penicillum chrysogenum by Disc Diffusion Method. Cinnamomum zeylan blume had the highest phenolic contents and the highest content of total volatile components. Tannins, Vit. E, Carotene and Vit. C recorded the highest values ( 300.2 mg / 100 ml sample, 0.95 micro Mol/ ml sample , 0.21 mg/ 100 ml sample and 7.2 mg/ 100 ml sample) for Citrus Aurantium l, Cinnamomum zeylan blume, Eiettaria Cardamorum motan and Citrus Aurantium l ; respectively. Galanga Galangal Alpinia officinarum recorded the lowest values in all components. These extracts showed good activity against the growth of food pathogenic Bacteria (Esherichia coli and Bacillus subtilis). The four extracts did not inhibit an Altеrnaria tenuis or Penicillum chrysogenum. The results of this study showed that (Cinnamomum Cassia blume, Eiettaria Cardamorum maton, Citrus Aurantium l and Alpinia officinalis L) extracts can be used as natural antimicrobial and antioxidant agents | ||||
