Abstract

The seasonal variation of phenol, tannin and ascorbic acid content has been investigated from leaves, stem, root and seeds of Trigonella foenum-graecum. Comparative account of phenol contents of Trigonella foenum-graecum showed higher level in leaves (range 4.973 to 5.102 mg/g dry wt.) than stem (range 2.704 to 3.019 mg/g dry wt.), root (range 1.006 to 1.123 mg/g dry wt.) and seeds (3.116 mg/g dry wt.). Comparative account of tannin contents of Trigonella foenum-graecum showed higher level in leaves (range 0.321 to 0.398 mg/g dry wt.) than stem (range 0.234 to 0.312 mg/g dry wt.), root (range 0.102 to 0.156 mg/g dry wt.) and seeds (2.745 mg/g dry wt.). Comparative account of ascorbic acid contents of Trigonella foenum-graecum showed higher level in leaves (range 2.785 to 3.276 mg/g dry wt.) than stem (range 1.698 to 2.109 mg/g dry wt.), root (range 0.831 to 1.076 mg/g dry wt.) and seeds (1.734 mg/g dry wt.).
