The mineral components of the Gastrodia elata Blum were determined by inductively coupled plasma-atomic emission spectrophtometry. The mineral component contents of the Gastrodia elata Blum were greater in the order of Fe < Na < Mg < Ca < P < K. The antioxidative effects of the Gastrodia elata Blum extracts on refined perilla oil were investigated by the rancimat method, peroxide value and TBA value. The antioxidative effects of Gastrodia elata Blum added to the refined perilla oil was increased with dose-dependent fashion in concentration of Gastrodia elata Blum extracts. The peroxide value and TBA value for their antioxidation stability were also lower than that of control. Antioxidation stability was increased in a dose-dependent manner.
