Abstract

Some Saudi herbs and spices were analyzed. The results indicated that mustard, black cumin, and cress seeds contain high amount of fat 38.45%, 31.95% and 23.19%, respectively, as compared to clove 16.63%, black pepper 5.34% and fenugreek 4.51% seeds. Cress, mustard, black cumin and black pepper contain higher protein contents ranging from 26.61 to 25.45%, as compared to fenugreek 12.91% and clove 6.9%. Crude fiber and ash content ranged from 6.36 to 23.6% and from 3.57 to 7.1%, respectively. All seeds contain high levels of potassium ranging from 383 to 823 mg-100g, followed by calcium ranging from 75 to 270 mg-100g, Magnesium ranged from 42 to 102 mg-100g and iron ranged from 20.5 to 65 mg-100g. However, zinc, manganese and copper were found at low levels. The major fatty acids in cress and mustard were linolenic acid 48.43% and erucic acid 29.81%, respectively. The lenoleic acid was the major fatty acid in black cumin, fenugreek, black pepper and clove oils being 68.07%, 34.85%, 33.03% and 44.73%, respectively. Total unsaturated fatty acids were 83.24, 95.62, 86.46, 92.99, 81.34 and 87.82% for cress, mustard, black cumin, fenugreek, black pepper and clove, respectively. The differences in the results obtained are due to environmental factors, production areas, cultivars used to produce seeds and also due to the different methods used to prepare these local spices.
