Nematicidal activity of Trigonella foenum-graecum L.

The aqueous, methanol and chloroform extracts of Trigonella foenum-graecum caused significant (p < 0.05) mortality of Meloidogyne javanica larvae. The methanol soluble fraction eluted from pure distilled water showed the highest (>92%) nematicidal activity compared with the fractions eluted from pure methanol and different ratios of chloroform and methanol indicate that the nematicidal compound was polar in nature.

Evaluation of the oral hypoglycaemic effect of Trigonella foenum-graecum L. (methi) in normal mice.

Trigonella foenum-graecum (Fenugreek) (Leguminosae) is employed as a herbal medicine. Its seeds are known for their carminative, tonic and antidiabetic effects. A curative dose of Trigonella foenum-graecum also produces antiulcer action. In this study we have investigated the hypoglycaemic activities of the aqueous extract of the seeds Trigonella foenum-graecum in normal mice using oral route of adminstration. The methanolic extract administered through the same route produced hypoglycaemic effect only at the dose of 1 g/kg body weight. The aqueous extract is under further investigation to determine the chemical structure of the active component. The presence of hypoglycaemic activity in aqueous and methanolic extract indicates that the active compounds are polar in nature.
