Contents on the CD Rom

  • Gamma-oryznaol, isolated from rice bran oil, is a naturally occurring mixture of plant chemicals called sterols and ferulic acid esters.
  • Gamma-oryzanol is an oryzayl alcohol ester of ferulic acid having an antioxidant action.
  • Gamma-oryzanol is a mixture of ferulic acid esters of mainly the phytosterols campesterol, beta-sitosterol, 24-methyl-cycloartenol and cycloartenol.
  • Gamma oryzanol (g-oryzanol) is an unsaponifiable component of rice oil, composed of several kinds of ferulic acids and has an effect similar to vitamin E.
  • Gamma Oryzanol from rice bran oil comprises advantageous antioxidant property and solve the health problem such as: reducing plasmacholesterol
    increasing testosterone levels, and treating menopausal disorder.
  • Soxhlet extraction method was the most common technique used in the extraction of lipid from plant and animal tissues. The extractability of rice bran lipid using this method has been reported in the range of 18 - 20%.
  • The oryzanol concentration may
    depend on factors such as plant varieties, processing methods employed, extracting solvent used and ratio of extracting solvent to bran as well as extracting solvent temperatures.
  • Purification and crystallization of oryzanol can be carried out
    using methanol-acetone solvent, producing a compound with antioxidant properties similar
    to tocopherols.
  • Gamma oryzanol is an important biological anti-oxidant present in rice bran oil in significant quantities.
  • Gamma oryzanol is a mixture of substances derived from rice bran oil, including sterols and ferulic acid. It has been approved in Japan for several conditions, including menopausal symptoms, mild anxiety, stomach upset, and high cholesterol.
  • Gamma-oryzanol is effective against climacteric melancholia and the butyric ester of riboflavin is also effective in preventing arteriosclerosis.
  • Gamma oryzanol intake include decreasing plasma cholesterol, decreasing platelet aggregation, decreasing hepatitic cholesterol biosynthesis, increasing fecal bile acid excretion and decreasing cholesterol absorption. Gamma-oryzanol has also been used in treatments for nerve imbalance and menopause disorders.
  • Oryzanol emulsions are used as antioxidants and preservatives for cosmetics and foods and such emulsions are also effective in preventing colour changes.
  • It is known to have anti-itching, anti-dandruff and anti-aging properties.
  • It is effective in trading broad range of gastrointestinal disorders including stress induced gastric and duodenal ulcers.
  • Oryzanol is sold abroad as an agent for body building in humans and for the treatment of nerve imbalance and disorders of menopause.
  • In the US, it is widely used as a sports supplement, as well as for reducing cholesterol.
