Abstract

|
Our research objective was to examine the in vitro biological activity of deer antler(Nogyong in Korean) extract, including the antioxidative, nitrite scavenging, and tyrosinase inhibitory effects, as well as the antithrombotic, and angiotensin I converting enzyme(ACE) inhibitory activities. The carbohydrate, protein, fat, and mineral contents of the deer antler were 7.6%, 65.3%, 3.2% and 23.9%, respectively. The electron donating ability(EDA) by the reduction of 2,2’-diphenyl-1-picrylhydrazyl(DPPH) was 67.1%, and the inhibition rate of lipid peroxidation by the thiocyanate method using linoleic acid was 92.1% in 100 mg/ml of extract. The nitrite scavenging effects were pH dependent, and were highest at pH 1.2 and lowest at pH 6.0. The sample inhibition rate against tyrosinase was above 64.0%. The platelet aggregation induced by ADP(adenosine-5’diphosphate) was inhibited up to 51.7%, and the inhibitory effect was dependent on the sample concentration. Lastly, the inhibition rate of ACE was 47.5% in 100 mg/ml of deer antler extract.
