Analysis Note

这些二级标准品为USP、EP（PhEur）和BP等主要标准品提供了多种可追溯性。

Application

抗坏血酸可用制药参考标准品，通过亲水作用色谱定量药物制剂中的分析物。

Biochem/physiol Actions

抗坏血酸，也称为维生素C，是由植物和一些动物物种（不包括人类和其他灵长类动物）产生的六碳内酯。抗坏血酸可作为多种酶的酶促辅助因子，可用作单加氧酶和双加氧酶的电子供体。抗坏血酸还起到强力抗氧化剂的作用，特别是对活性氧。

General description

用于质量控制的制药二级标准品，为制药实验室和制造商制备内部工作标准品提供了一种方便、高性价比的替代方案。抗坏血酸是一种强大的抗氧化剂，广泛用于药物制剂中。经证其对衰老相关疾病（如癌症、动脉粥样硬化、眼病、神经退行性疾病等）具有有益作用。它主要参与胶原蛋白的形成和维持。饮食长期缺乏抗坏血酸会导致坏血病。
