【摘要】 二氢杨梅素可开发利用价值极大,它的抗氧化活性更是研究的热点。本研究通过量子化学计算手段和实验醚化处理相结合,确定了二氢杨梅素分子结构的抗氧化活性中心在其B环上的3’、4’、5’位连酚羟基结构,同时也验证了量子化学计算在研究黄酮类物质分子结构与表现性质中的正确预测性和指导性。更多还原

【Abstract】 Dihydromyricetin (DMY) has bright prospects to be explored and used. Its antioxidant activity is the focus of research. The paper ascertains antioxidant center of dihydromyricetin molecular structure existing on B loop 3’, 4’, 5’ location of phenol hydroxy by etherifying reaction in combination with quantum chemistry computation. It also validates quantum chemistry method predictable on the relationship between performance and molecule structure of flavonols.更多还原
