B-extract has been extensively studied for its
anti-oxidant activity and anti-tumor effect. However,
to the best of our knowledge, the present study is the
first investigation on the preventive and therapeutic
effect of B-extract in the context of a SD model.
In summary, the present study demonstrated that
B-extract improved the learning and memory ability
of dementia model rats by regulating the activities of
the key enzymes for the biosynthesis and degradation
of neurotransmitters, changing the contents of cholinergic,
monoamine, and amino acid neurotransmitters
in the hippocampus. Thus, the B-extract showed
significant therapeutic effects. However, the detailed
mechanism of this function needs further investigation
