  • The deodorizing responses of the steam distillate from some medicinal plants(G-3) on three representative malodors were evaluated by estimating the best estimate threshold(BET) of odor responses. With a single spray of G-3, the BETs of malodors such as ammonia, acetic acid, and ethyl acetate were found to increase 4.11, 32.6 and 13.1 fold, respectively, which indicated G-3 possessed a potent deodorizing activity. The deodorizing potency of G-3 was also demonstrated to be as high as and even higher than those of the commercial deodorizing agents.

  • The acute toxicity and the effect of steam distillate obtained from several plant mixtures (G-3) on the reactivation of brain, lung, and blood acetylcholinesterase (AChE) activity, and recovery from other toxic symptoms following intoxication by organophosphate pesticides were investigated in mice and mudfish. Administration of G-3 $(50{\sim}100\;ml/kg,\;i.p.)$ immediately or 30 min prior to Diazinon or Sumithion treatments, respectively, resulted in a significant reactivation of AChE activity in brain, lung, and blood, their potencies being almost equipotent to those of 2-PAM, one of well-known antidotes. G-3 itself exhibited almost no acute toxicity even at the highest dose employed, and without effect on the inhibition of hepatic drug metabolism function following organophosphate administrations. G-3 showed a significant diminution of the death rate in mudfish as well as in mice intoxicated by Diazinon.

  • The repellent activity of methanol extracts from 8 aromatic medicinal plant species and a steam distillate against blood-starved Aedes aegypti (L.) females was laboratory examined by skin test and compared with that of N,N-diethyl-m-toluamide (deet). Reponeses varied according to Plant species. At a dose of $0.1mg/\textrm{cm}^2$, potent repellency against adult mosquitoes was obtained with extracts of Cinnamomum camphora (94.1 %) Cinnamomum cassia bark (91.2%), Eugenia caryophyllata flower bud (72.2%), and Tilia amurensis (69.4%). Repellent activity of these plant extracts was comparable to that of deet (83.4%). The plants described merit further study as potential mosquito-repellent agents.
