Ctrl, control test; L, longifolene; LC, longicamphenylone; LL, norlongilactone; LA, longicamphenylol; LAc, longifolic acid; LOX, longifolene oxide; isoLAc, isolongifolic acid; LHK, longifolene–hydroxy ketone; NF, no-feed test. Bars indicate standard errors. Common letters indicate that there is no significant difference in the values. Asterisks denote a significant difference between sample and control papers; Tukey–Kramer test, p < 0.05
