A crude hydroalcoholic extract from Hibiscus sabdariffa L. calyces showed in vitro an appreciable enzyme-inhibiting activity towards the Angiotensin I Converting Enzyme (ACE), attributable to flavones, but weak inhibiting activities towards elastase, trypsin and alpha-chymotrypsin. The angioprotective activity in vivo, also important, was due to flavones and anthocyanins.
来自玫瑰茄萼片的粗制水醇提取物在体外对血管紧张素I转换酶（ACE）显示出明显的酶抑制活性，这归因于黄酮类化合物，但对弹性蛋白酶、胰蛋白酶和α-胰凝乳蛋白酶的抑制活性较弱。体内血管保护活性也很重要，这归因于黄酮类化合物和花青素。
