1

a
:an acid obtained from alpha-truxilline by hydrolysis or from cinnamic acid by irradiation — called also
alpha-truxillic acid
b
:an acid obtained from alpha-truxillic acid by heating with acetic anhydride and sodium acetate and convertible again into the alpha isomer by stronger heating — called also
gamma-truxillic acid
