Abstract
Antibacterial and antioxidative actions of ascorbyl caprate (AC), ascorbyl laurate (AL), ascorbyl myristate (AM) and ascorbyl palmitate (AP) synthesized by the authors and also ascorbyl stearate (AS) obtained commercially were investigated.AC, AL and AM showed antibacterial activity against B. subtilis and S. aureus, but AP and AS did not. None of the esters, on the other hand, had such action against E. coli, but AC displayed antibacterial activity against E. coil when sodium hexametaphosphate (HP) was added at the same time, and the combination of 0.2% HP and 0.4% AC showed bactericidal activity against E. coll.Antioxidative activities of AC, AL, AM and AP were as potent as that of AS.
