| Description | Malvidin-3-glucoside chloride (Oenin chloride) has antioxidant activity, alone is not oxidized in the presence of grape polyphenol oxidase. Malvidin-3-O-glucoside chloride's color stabilization at a higher pH can be explained by self-aggregation of the flavylium cation and copigmentation with the Z-chalcone form. |
| In vitro | 在本研究中，我们利用含有超螺旋DNA质粒的凝胶电泳分析法，检测了这些化合物的三项活性：(1) DNA插入作用；(2) 通过抑制质粒放松活性（催化抑制）和稳定可切割的DNA-拓扑异构酶复合物（中毒）来抑制人类拓扑异构酶I；(3) 抑制或促进氧化性单链DNA断裂。结果表明，在生理pH范围内，对于本研究所用的所有化合物—花青素氯化物、Malvidin-3-O-glucoside chloride、花青素3,5-O-二葡萄糖苷、锦葵素-3-O-葡萄糖苷氯化物以及黄酮素氯化物，我们未发现任何DNA插入的证据。这些花青素仅在高浓度(> 50 muM)下抑制拓扑异构酶的松弛活性，且我们未找到这些化合物稳定拓扑异构酶I可切割复合物的证据。 |
