Abstract: | Erythroxylum species have several traditional uses in different countries, including the treatment of hypertension. The ethanol extract from E. gonocladum aerial parts, a species endemic to the Brazilian cerrado, elicited a concentration-dependent inhibition of angiotensin converting enzyme (ACE) (pIC50=4.53±0.05). Extract fractionation led to the isolation of two compounds, whose structures were assigned by spectrometric data as astilbin and β-sitosterol, along with a mixture of palmitic, stearic and linolenic acids. This is the first report on the occurrence of these compounds on E. gonocladum. Astilbin promoted significant ACE inhibition in vitro (pIC50=5.86±0.33) and its activity did not differ from captopril, when both compounds were assayed at 10 μM concentration. |
