The toxic action of seven species of Chinese medicinal herbs against Tribolium castaneum (Herbst) is preliminarily studied in the paper. The results showed that, by fumigating method, the volatile oil of Zanthaxylum bungeanum Maxim had significant activity against larvae, pupas and adults, but no significant relationship between the concentration of the volatile oil of Acarus calamus L. and the mortality of the test insects. The toxic action of the volatile oil of Notopterygium incisium Ting was not obvious....

The toxic action of seven species of Chinese medicinal herbs against Tribolium castaneum (Herbst) is preliminarily studied in the paper. The results showed that, by fumigating method, the volatile oil of Zanthaxylum bungeanum Maxim had significant activity against larvae, pupas and adults, but no significant relationship between the concentration of the volatile oil of Acarus calamus L. and the mortality of the test insects. The toxic action of the volatile oil of Notopterygium incisium Ting was not obvious. With toppical applications, the order of the toxic extent of the four crude extracts was as follows, Curcuma longa auct. non L. Paeonia suffruticosa Andr. > Chenopodium ambrosioides L. > Brucca jaranica Merr Being mixed with one and another, P. suffruticosa Andr. had significant synergism to the other three crude extracts P. suffruticosa Andr. and B. jaranica Merr. and Curcuma longa were the best mixed formula.

本文探讨了我国七种药用植物对赤拟谷盗Tribolium casianeum(Hercst)的致死作用。结果表明:采用熏蒸法,花椒(Zanthaxylum bungeanum Maxim)挥发油对赤拟谷盗幼虫、蛹、成虫等虫态均具有较显著的活性作用;菖薄(Acorus calamus L.)挥发油对试虫的致死作用与挥发油的浓度无明显相关性;羌活(Notoperygium incisium Ting)挥发油对试虫致死作用不显著。采用微量点滴法,姜黄(Curcuma domestica Valeton)、丹皮(Paeonia suffruticosa Andr.)土荆芥(Chenopodium ambrosioides L.)、鸦胆子(Brucea javanicaMerr.)等四种药用植物的粗提物对试虫的致死作用大小顺序为:姜黄>丹皮>土荆芥>鸦胆子,这四种粗提物两两混用时,丹皮粗提物对其它三种粗提物均具有显著增效作用。丹皮—鸦胆子—姜黄为最佳混合配方。

The chemical composition of the volatile oil from Chenopodium ambrosioides L.grown in Hubei was analysed by GC/MS/DS technique.Eighty components have been identified.The major components were menthol (31 33%),α terpinene (13 21%),carvomenthenol (8 53%),p cymene (8 34%),and 1,8 cineole (7 42%) etc.The total content of the 80 components is 99 112% of the volatile oil.

用色谱-质谱联用技术对湖北产土荆芥挥发油的化学成分进行了分析。鉴定了80种组分。其中主要组分是:薄荷醇(31.331%)、α-松油烯(13.210%)、香芹艹孟烯醇(8.526%)、对伞花烃(8.343%)、1,8-桉叶油素(7.417%)等5种化合物。被鉴定的80种成分,共占挥发油总含量的99.112%。

The essential oil from Chenopodium ambrosioides L. was obtained by steam distillation. The chemical compositions were separated and identified by GC-MS. 48 Chemical constituents were separated and identified. Monoterpenes, sesquiterpenes and their oxo-derivatives are the major chemical constituents in the oil. The main compounds were germacrene D, β-caryophyllene, germacrene B,β-elemene,Curzerene,β-thujene and α-cadinol. The relative contents in the essential oil were determined by area normalization.
