Larvicidal activity of medicinal plant extracts and lignan identified in Phryma leptostachya var. asiatica roots against housefly (Musca domestica L.).[Pubmed:22065063]
Parasitol Res. 2012 May;110(5):1849-53.
Medicinal plant extracts from 27 plant species in 20 families were tested for their larvicidal activity against housefly, Musca domestica (L.). Responses varied with plant material and concentration. Among plant species tested, Phryma leptostachya var. asiatica showed 100% larvicidal activity against M. domestica at 10 mg/g concentration. Larvicidal activities of Atractylodes japonica, Saussurea lappa, Asiasarum sieboldi, and Gleditsia japonica var. koraiensis were 89.3%, 85.3%, 93.3%, and 96.6% at 10 mg/g concentration, respectively. Extracts of Prunus persica, Curcuma longa, and Paeonia moutan produced moderate activity. Larvicidal activity of other plant extracts was less than 50%. Among test plant species, P. leptostachya var. asiatica showed the most potent larvicidal activity. The active constituent of P. leptostachya var. asiatica roots was identified as the Leptostachyol acetate by spectroscopic analysis. The LC(50) values of Leptostachyol acetate against M. domestica larvae were 0.039 mg/g. Naturally occurring medicinal plant extracts and P. leptostachya var. asiatica root-derived compounds merit further study as potential housefly larval control agents or lead compounds.
Larvicidal activity of lignans identified in Phryma leptostachya Var. asiatica roots against three mosquito species.[Pubmed:15713007]
J Agric Food Chem. 2005 Feb 23;53(4):969-72.
The insecticidal activity of phytochemicals isolated from the roots of Phryma leptostachya var. asiatica against third instar larvae of Culex pipiens pallens, Aedes aegypti, and Ocheratatos togoi was examined. The two constituents of P. leptostachya var. asiatica roots were identified as the Leptostachyol acetate (I) and 8'-acetoxy-2,2',6-trimethoxy-3,4,4',5'-dimethylenedioxyphenyl-7,7'-dioxabicyclo[3 .3.0]octane (II) by spectroscopic analysis. Compound I was lethal to C. pipiens pallens, A. aegypti, and O. togoi at 10 ppm. Compound II showed weak or no insecticidal activity against three mosquito species at 10 ppm. The LC(50) values of I against C. pipiens pallens, A. aegypti, and O. togoi were 0.41, 2.1, and 2.3 ppm, respectively. Naturally occurring P. leptostachya var. asiatica root-derived compounds merit further study as potential mosquito larval control agents or lead compounds.
