| Description |
Germinating seeds tend to release a variety of bioactive compounds into
the surrounding medium and their compositions vary depending on the
type of seed and the temperature of the medium. During imbibition, green
gram seeds exuded polyphenols and proteins, and their contents were
higher at 45°C (warm seed) compared with that obtained from seeds
soaked at room temperature. The total exudate from warm seeds also
showed higher antioxidant activity compared with that of room-temperature
exudate. Hence, the ethanol extract of the warm seed exudate was
characterized for its health beneficial effects. Phenolic acids like gallic,
ferulic, and sinapic acids, and flavonoids like vitexin and isovitexin were
identified in the extract of the exudate. Among these, vitexin content was
the highest compared to other bioactive compounds. DPPH radical scavenging
activity and reducing power of the extract were comparable to those
of butylated hydroxyanisole (BHA). Ethanol extract of warm seed exudate
showed acetylcholinesterase (AChE) inhibition with an IC50 value of 9.6 μg
GAE/ml and 72% inhibition of platelet aggregation at 0.11 mg GAE/ml
concentration. High MW protein (>150kDa) of the exudate showed 83%
inhibition of platelet aggregation at a concentration of 1 mg/ml. Low MW
proteins of 29 kDa and 12 kDa showed 50% AChE inhibition at 8 μg/ml and
6.82 μg/ml concentrations, respectively.
