Nutritional and nutraceutical properties of different plant parts of fenugreek (Trigonella foenum-graecum L.)
Keywords:Fenugreek leaves and seeds, growth stages, quality, mineral contents
Studies on influence of different growth stages on physiological and biochemical parameters of fenugreek (Trigonella foenum-graecum L.) was carried out at HC & RI, TNAU, Coimbatoreduring 2017-18. Seven different plant parts viz., young seedlings (7-10 days after germination), fresh leaf at matured stage (30-40 days after sowing), dry leaf at matured stage (30-40 days after sowing), fresh leaf at matured stage (60-70 days after sowing), dry leaf at matured stage (60-70 days after sowing), dry seed and sprouted seed were tried. The study revealed that, the sprouted seeds and the dried seeds were found to be best with higher quality parameters viz., total protein, total carbohydrate, total phenol, total fat, crude fibre, calcium, magnesium and iron contents. On the other hand, the fresh leaves at matured stage (60-70 days after sowing) recorded higher (54.37 mg 100g-1) ascorbic acid content. The chlorophyll ‘a’, chlorophyll ‘b’ and total chlorophyll content in fresh fenugreek leaves ranged from 2.07 to 2.19 mg g-1, 1.02 to 1.16 mg g-1 and 3.09 to 3.35 mg g-¹ respectively, while dried leaves had lower total chlorophyll content ranged from 0.983 to 1.18 mg g-¹.
