Relationships between Antioxidants and Quality Characteristics from Velvet Antlers of Formosan Sambar Deer.

The quality characteristics of velvet antlers obtained from Formosan sambar deer ( Swinhoi) (SDVA), harvested from 63 to 81 d during the velvet antler growth period, were evaluated by investigating the relationships between antioxidant levels; including content, activity, and content/activity ratios, and physical properties; including shear force values, color, and Ca content. The hardness of samples from base velvet antler sections increased, and that the color of these samples tended to become reddish-yellow (redder and more yellow), suggesting that the Ca content in the base section of the sample was not ossified yet. Samples from the upper sections of velvet antler showed higher superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) content (3.

Effects of deer velvet extract from Formosan sika deer on the embryonic development and anti-oxidative enzymes mRNA expression in mouse embryos.

Ethnopharmacrological Relevance: The deer velvet or its extracts has been widely used in clinic. It has been used in promoting reproductive performances and treating of oxidation and aging process. The aim of this study is to investigate the effects of velvet extract from Formosan sika deer (Formosan sika deer; Cervus nippon taiouanus, FSD) velvet on mouse embryonic development and anti-oxidant ability in vitro.
