ABSTRACT
The study determines the anti-inflammatory activities of malunggay (Moringa oleifera) bark, gumamela (Hibiscus rosa-sinensis) flower and Langka (Artocarpus heterophyllus) bark on white mice.
The study, conducted within Philippines Science High School campus, resulted in langka bark inhibiting inflammation by 78.21%; gumamela flower, 56.21%; and malunggay leaf, 50.98%. Meanwhile, indomethacin, a commercial anti-inflammagen, inhibited inflammation by 100%. These results were obtained using the carragenan-induced edema method, a bio-assay on anti-inflammatory activities (Guevarra, Vargas and Uy,1996).
The statistical tool used in the study to compare the results was the analysis of variance (ANOVA) and calculations show that the anti-inflammatory activities of the plant extracts do not differ significantly; their properties, however, differ significantly with that of indomethacin.
