“…Therefore, we are interested using the monoterpenoids that is a component of refined oil, which is found in stable supply in plants, in the synthesis of a compound that can might be a treatment against insanitary insects and we have previously reported a lot of interesting results (13,14). Therefore, this time, we have incorporated into the monoterpene carboxylic acid (geranic acid (1), perillic acid (2), myrtenic acid (3), and a-campholenic acid (4)) and ginseng, which are known to kill insects and to have an antibacterial action, as part of our ongoing study.…”
