Piscicidal activity

When Mr. Watanabe (now Prof. Watanabe at the University of Tokyo) and I tasted the synthetic samples, both (—)-64 and (+)-64 were extremely hot-tasting. Examination of piscicidal activity by Prof. Asakawa and that of antifeedant activity by Prof. Pickett showed no difference between the enantiomers of polygodial. In this particular case, both the enantiomers 64 and 64 showed the same bioactivity.44... 

Justicidin A and B (85, 86) (Fig. 8.17), from Justicia hayatai, have piscicidal activity as powerful as that of rote-none (Davin et al., 1992).

Marchantia polymorpha (probably Conocephalum supradecompositum) (24, 26) contains a piscicidal component. The active compound was ( + )-costunolide (406) which showed moderate piscicidal activity, TLm 2 ppm against killie-fish (Oryzia latipes) (172). Costunolide inhibited penetration of cercariae of the trematode Schistosoma mansoni (77).
