Zanthoxylum tsihanimposa

Zanthoxylum tsihanimposa Rutaceae 1 bowl, 3-4 times daily... 

The antiplasmodial activity of five akaloids (y - fagarine, N-benzoyltryamine, skimmianine, dictamnine and 4-methoxy-l methyl-2(lH)-quinoline), extracted by decoction from Zanthoxylum tsihanimposa stem bark were tested upon P. falciparum. The quinoline alkaloid y-fagarine was the most potent of five alkaloids, being found to be 3. 4 times more active than dictamnine and 1.4 times more active than skimmianine. The presence of the methoxy group in positions C4 and C8 appears to be important for bioactivity (20). 

Nitidine was isolated from the root bark and root of Zanthoxylum nitidum, which is a woody climber of the Rutaceae (4). The same compound has been isolated from Zanthoxylum tsihanimposa (root) and Z. ailanthoides (root). It is also present in the stem bark of Zanthoxylum americanum together with coumarins (44).
