Two kinds of high melting Point ferulates (mp 185.3186.5°C and 190.7191.7°C) as phenolic substances have been confirmed in the soapstock of rice bran oil. The formulas of these two ferulates have been established as same formula, C41H60O4.
By saponification with alcoholic potassium hydroxide solution, these two ferulates have been converted into ferulic acid and two kinds of triterpenoid alcohols C31H52O having different melting points (170.5171.0°C and 179.4181.0°C).
