| Authors: | S.E. El-Gengaihi, H.E. Wahba |
| Abstract:
Ginger cultivated in Egypt possessed a low amount of oil in the shoots. The chemical constituents of the volatile oil of this oil showed similarity to that of rhizomes. It contained a higher percentage of oxygenated monoterpenes from which geranyl acetate is the major component. This is different from the oil of rhizomes which contained lower amount of geranyl acetate. The other constituents fluctuated considerably. Oleoresin ranged from 4 to 8%. The yield of both shoots and rhizomes increased by age till the summer months then decreased in the fall months. | |
