Abstract
MeOH extracts, fractions and pure substances from Musanga cecropioides, Cecropia species and Crataegus oxyacantha /C. monogyna were screened by using an in vitro bio-assay based on the inhibition of Angiotensin Converting Enzyme (ACE), as measured from the enzymatic cleavage of the chromophore-fluorophore-labelled substrate dansyltriglycine into dansylglycine and diglycine. Phenolic acids showed no significant ACE-inhibition whereas flavonoids and proanthocyanidins demonstrated inhibitory activity at 0.33 mg/ml using this test system.Entities:
