Palmatine from Plants ≥96%
Odor: characteristic
Use: Palmatine has been used in the treatment of jaundice, dysentery, hypertension, inflammation, and liver-related diseases. This compound could potentially be developed for the treatment of flavivirus infections Palmatine is an inhibitor of dopamine generation. It also acts as a selective topoisomerase I and II position and as vasodilator that effectively reduces Ca2+ concentrations. Palmatine caused strong fluorescence quenching of Hb by the static quenching mechanism, but with differing quenching efficiencies.
