Fenugreek (Trigonella foenum-graecum L.) has enormous nutritional and medicinal values. Its herbaceous leaves and seeds are
being used for human consumption since centuries. This study evaluated the diversity of certain phytochemicals (total phenolic
contents, flavonoids, saponins and tannins,) in seeds of twenty Omani fenugreek accessions. The fenugreek plant material
used in this study was obtained from the Germplasm Collection Centre, Ministry of Agriculture and Fisheries (MAF), Oman. The
seeds were planted and morphologically evaluated using biodiversity international passport and then the seeds obtained from the
first and second season harvests were used for their phytochemical analysis. Significant (P<0.05) variability was observed in the
mean values for total phenolic contents (TPC), saponins, flavonoids and tannins, in seeds of various fenugreek accessions. The
values in various accessions ranged for TPC from 107.88 to 216.47 mg GAE/100g; for saponins from 7.27 to 17.03g/100g; for
flavonoids 8.46 to 32.81 mg CAE/100g and for tannins from 30.21to 74.54 mg CAE/100g, respectively. The results indicated that
accession #49 had the highest TPC (216.47 mg GAE/100g), saponins (17.03g/100g) and flavonoids (32.81 mg CAE/100g), while
the highest tannin content was recorded in accession #209 (74.54 mg CAE/100g). Accession #63 exhibited the maximum ferric
reducing antioxidant power (FRAP) value (0.259 mMoles/L) compared to all other accessions. Our findings showed that a
broader diversity exists in the seeds of various fenugreek accessions with respect to their phytochemical composition and
antioxidant activities. The selection of potential fenugreek accessions for future dissemination should therefore be based on
their phytochemical composition and antioxidant potential properties to harvest the maximum health benefits.
