(A) Effect of different flavonoids on Angiotensin Converting Enzyme (ACE) activity.

<p>Purified lung ACE was preincubated at 37°C for 30 min in the presence of 100 µM of flavonoids or DMSO as a control. The results are expressed as the percentage of ACE inhibition. The plot represents the mean result ± SD from three experiments. (<b>B</b>) Effect of different flavonoids on Angiotensin Converting Enzyme (ACE) activity. Purified lung ACE was preincubated at 37°C for 30 min in the presence of 500 µM of flavonoids or DMSO as control. The results are expressed as the percentage of ACE inhibition. The plot represents the mean ± SD from three experiments.
