Effect of Trigonella foenum-graecum Linn. seeds methanol extract on learning and memory.

Prevention and delay in the onset of memory disorders will have a great impact on society by reducing the disease burden and finances. Drugs available for the treatment of learning and memory disorders are few. There is need to develop a better drug, several studies have shown the therapeutic effectiveness of herbal extracts for the learning and memory disorders because of their neuroprotective effects, hence herbs should be evaluated scientifically to form a basis for the future discovery of newer drugs. In this study, effect of Trigonella-foenum graecum L. seeds methanol extract (TFGS-ME) was evaluated in mice on learning and memory process by both exteroceptive and interoceptive behavioral models at three different doses. Elevated plus maze test was employed to assess the effect on learning and memory as an exteroceptive behavioral test. Scopolamine-induced amnesia was performed to assess effect on learning and memory as interoceptive behavior test. In both tests, it was found that animals received extract at 200 mg/kg exhibited a highly noteworthy decline in transfer latency on both acquisition and retention days in contrast to control animals, suggestive of improved learning and memory process. Results were equivalent to the standard drug piracetam at similar dose indicating that TFGS-ME improves learning and memory process and has significant potential as an antiamnesic agent. Hence there is need to separate the dietary components which may play a vibrant role in the future invention of novel drugs.
