The use of Aspilia africana in traditional medicine for the management of ocular diseases has been reported in India and some indigenous communities of Africa. The aim of this study was to investigate the aqueous extract of the flowers of A. africana (AAE) as an anticataract remedy using murine models of diabetic and senile cataracts. Methods. Preliminary phytochemical screening of the extract, in vitro antioxidant assays, and in vitro aldose reductase inhibitory activity were performed. For anticataract investigations of the extracts, diabetic cataract was induced by galactose administration in 3-week-old Sprague Dawley rats. The evaluation of experimentally induced age-related cataract was performed by administering sodium selenite to 10-day-old rat pups. Results. The phytochemical analysis revealed the presence of alkaloids, tannins, flavonoids, glycosides, and saponins. In vitro aldose reductase inhibitory property of the extract on rat lenses revealed that the AAE inhibited the enzyme activity with IC50 of 12.12\u2009\u00b5g\/ml. For the anticataract investigations, 30, 100, and 300\u2009mg\u00b7kg\u22121AAE-treated rats recorded significantly low (<jats:inline-formula>\n                     <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>p<\/a:mi>\n                        <a:mo>\u2264<\/a:mo>\n                        <a:mn>0.0001<\/a:mn>\n                     <\/a:math>\n                  <\/jats:inline-formula>) cataract scores compared to the negative control rats, indicating a delay in cataractogenesis from the second week of treatment in the galactose-induced cataractogenesis. Similarly, the treatment with AAE caused a significant reduction (<jats:inline-formula>\n                     <c:math xmlns:c=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\">\n                        <c:mi>p<\/c:mi>\n                        <c:mo>\u2264<\/c:mo>\n                        <c:mn>0.0001<\/c:mn>\n                     <\/c:math>\n                  <\/jats:inline-formula>) in cataract scores compared to the negative control rats in the selenite-induced cataractogenesis.
