In the current study, we isolated a proanthocyanidin oligomer from the hulls of red-kerneled rice. The structure of the oligomer was characterized based on spectral data and chemical reaction. Furthermore, two anthocyanins were isolated from the beards of the same source. The proanthocyanidins and beard extract showed more potent inhibitory and cleaving activities than those of positive controls, respectively.
在本研究中，我们从红米稻壳中分离出一种原花青素低聚物。基于光谱数据和化学反应对该低聚物的结构进行了表征。此外，还从同一来源的稻芒中分离出两种花青素。原花青素和稻芒提取物分别表现出比阳性对照更强的抑制活性和裂解活性。
