Abstract
Conclusion of Parkia biglobosa bark:
The results of the complement-fixation bioactivity as well as the macrophage stimulation tests carried out to elucidate the ability of the investigated polysaccharides to modulate the function of the immune system were highly active and typical of the characteristics of the bioactive pectins.
Although, the sample S100i-1 was highly active regarding the complement-fixation bioactivity test, the results obtained from the stimulation of macrophages showed sample S50 to be the most potent in releasing nitric oxide.
