| Description
| - The systemic effects of phytoecdysteroids were investigated by applying tested compounds to the roots of the rape plants. Evaluation of the effects was based on mortality, longevity, rate of development and fecundity of the cabbage aphid (Brevicoryne brassicae L., Sternorrhyncha: Aphididae) feeding on the shoot of the treated plants. The major ecdysteroid compounds tested were natural products isolated from a medicinal plant Leuzea carthamoides DC (Willd.) Iljin (Asteraceae): 20-hydroxyecdysone (20E), ajugasterone C (ajuC) and polypodine B (polyB). The compounds were tested in two concentrations (0.07 and 0.007 mg/ml) in water. In addition, we have also investigated the systemic effects of a special Lc-Ecdy 8 fraction isolated from L. carthamoides, which contained 20E, ajuC and polyB and at least six other minor compounds in addition to the above indicated ecdysteroids. HPLC analysis of the Lc-Ecdy 8 fraction indicated the presence of makisterone A and inokosterone in minor quantities. It appeared th

- Systémové účinky phytoecdysteroidů byly testované pomocí metody sání látek přez kořenový systém rostlin. Jako parametry účinnosti bylo sledováno; mortalita, dlouhověkosti, délka vývoje a následná plodnost mšice zelné (Brevicoryne brassicae L., Sternorrhyncha: Aphididae). Majoritní ecdysteroidní testované separace byly přirozenými metabolity izolované z léčivých rostlin Leuzea carthamoides DC (Willd.) ) Iljin (Asteraceae): 20 hydroxyecdysone (20E), ajugasterone C (ajuC) a polypodine B (polyB). Směsi byly testované ve dvou koncentracích (0.07 a 0.007 mg./ml) rozpuštěných ve vodě. Navíc, my také jsme vyšetřovali systémové účinky ekdysteroidní frakce Lc- Ecdy 8 izolované z L. carthamoides, který obsahoval 20E, ajuC a polyB a přinejmenším šest dalších menších ecdysteroidů. HPLC analýza z Lc- Ecdy 8 indikovala makisterone a inokosterone v menších množstvích. Bylo zjištěno, že všechny testované ecdysteroidy, s výjimkou nejběžnější, 20E, snížily plodnost mšic, která sála na ošetřených rostlinách rostliny. M (cs)
