纳米六味地黄液的制备与性能
Keywords: 有机高分子材料,micros超细粉碎机
Abstract:
？用micros超细粉碎机制备纳米六味地黄液,对其显微结构、稳定性和体外溶出度进行了表征,研究了服用六味地黄液的小鼠血清中的sod对邻苯三酚自氧化速率的抑制率.结果表明,六味地黄药材纳米粉碎后,细胞壁、细胞膜大部分被破碎,有效成分可直接溶出.纳米化使六味地黄液的稳定性得到改善.六味地黄细粉的指标成分--丹皮酚的溶出与时间呈线性关系,而纳米六味地黄中丹皮酚的溶出与时间之间没有线性关系.服用纳米六味地黄液45min后,六味地黄的累积溶出度比细粉的溶出度高.服用纳米六味地黄组的老龄小鼠血清的sod活性显著高于细粉组(提高67%),即六味地黄纳米化使抗衰老的药效得到提高.
