A High Melting Point Ferulate from Soapstock of Rice Bran Oil

Abstract

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).
