Total synthesis of(-)-periplanones C [(-)-PC; 1] and D [(-)-PD; 2] was achieved starting from (-)-germacrene D via 7 and 8 steps, respectively, according to the similar route on syntheses of racemic PC and PD. The 1H NMR and GC mass spectra of 2 unambiguously determined the structure of the natural sample of PD which was isolated from Periplaneta fuliginosa. Bioassay of synthetic samples of 1 and 2 was carried oat against males of P. fuliginosa, P. americana, and P. japonica. 10-9 g of 1 elicited significant response in males of P. americana and P. japonica. 10-10 g of 2 elicited strong response in P. fuliginosa males, whereas it showed significantly weak response against males of P. americana and P. japonica. Almost same degree of activities was observed between 1 and 2 against males of P. americana and P. japonica at 10-10 g dose.

Humulene (I), (-)-germacrene-D (II), and (-)-germacra-4(15),5(E),10(14)-trien-1β-ol (III) were isolated from the fruits of Torilis japonica.The latter two compounds (II and III) were determined to have optical purities of about 40 and 30percent, respectively.Keywords-Torilis japonica; humulene; germacrene-D; germacra-4(15),5(E),10(14)-trien-1β-ol; optical purity
