We present the nutritional composition, antioxidant activity, and pharmacological effects of three processed velvet antler products [antler powder (AP), antler slice (AS), and honey antler slice (HAS)] prepared in our laboratory. The nutrient profile of crude protein, fatty acids, amino acids, mineral elements, and nucleosides were established. The antioxidant activity was measured. The effects of three extracts on kidney-yang deficiency, induced by hydrocortisone, in mice were investigated. The nutrition composition of HAS was relatively low owing to its high moisture. AP, AS, and HAS extracts all exhibited concentration-dependent activity in DPPH*, ABTS, and FARP antioxidant assays. HAS had similar effect with AP and AS in improving oxidative stress in mice with kidney-yang deficiency, moreover, it could improve the serum cAMP level much significantly than the others. The processing without repeated heating might contribute in preserving more bioactive components in HAS, which could be the explanation of its excellent efficiency in relieving kidney-yang deficiency.

加工后的鹿茸：营养成分，体外抗氧化能力和减轻小鼠肾阳虚的症状

我们介绍了在我们的实验室中制备的三种鹿茸产品的营养成分，抗氧化活性和药理作用[鹿茸粉（AP），鹿角片（AS）和蜂蜜鹿角片（HAS）]。建立了粗蛋白，脂肪酸，氨基酸，矿物质和核苷的营养成分。测量抗氧化剂活性。研究了三种提取物对氢化可的松所致小鼠肾阳虚的影响。HAS的营养成分由于其高水分而相对较低。AP，AS和HAS提取物在DPPH *，ABTS和FARP抗氧化剂测定中均显示出浓度依赖性的活性。HAS与AP和AS在改善肾阳虚小鼠的氧化应激中具有相似的作用，此外，它可以显着提高血清中的cAMP水平。无需反复加热的处理可能有助于保留HAS中更多的生物活性成分，这可以解释其在缓解肾阳虚方面的出色功效。
