In a study[1] on rat astrocyte primary cultures, berberine and the alkaloid extract of B. aetnensis roots were able to restore the oxidative status modified by glutamate and the levels of TG2 to control values. Consequently berberine or the alkaloid extract of B. aetnensis roots are able to ameliorate the excessive production of glutamate, protein misfolding and aggregation, mitochondrial fragmentation, and neurodegeneration.

Phytother Res 2011;25:816-20. PMID: 21086546. DOI. Berberis aetnensis C. Presl. is a bushy-spiny shrub common on Mount Etna (Sicily, Italy), containing various alkaloids with several pharmacological properties. This study assessed the effect of berberine and of the alkaloid extract of B. aetnensis roots on the glutamate-evoked tissue transglutaminase (TG2) up-regulation in rat astrocyte primary cultures, used as an in vitro model of excitotoxicity. The findings show that the alkaloid extract of B. aetnensis roots consists mainly of berberine. Furthermore, berberine and the alkaloid extract of B. aetnensis roots were able to restore the oxidative status modified by glutamate and the levels of TG2 to control values. It was found that berberine or the alkaloid extract of B. aetnensis roots are able to ameliorate the excessive production of glutamate, protein misfolding and aggregation, mitochondrial fragmentation, and neurodegeneration. Thus, it is suggested that berberine and the alkaloid extract of B. aetnensis roots, may represent a natural therapeutic strategy in the neuropathological conditions associated with excitotoxicity.
