Larvae of the cabbage looper, Trichoplusia ni (Lepidoptera: Noctuidae), often transect leaves with a narrow trench before eating the distal section. The trench reduces larval exposure to exudates, such as latex, during feeding. Plant species that do not emit exudate, such as Plantago lanceolata, are
In screening a library of plant extracts from ~1000 species native to the Southeastern United States, Lobelia cardinalis was identified as containing nicotinic acetylcholine receptor (nicAchR) binding activity which was relatively non-selective for the α4β2- and α7-nicAchR subtypes. This nicAchR
A mechanism of antidepressant activity of beta-amyrin palmitate was studied using the forced swimming method in mice. Beta-amyrin palmitate (10 mg/kg) reduced the increase in the duration of immobility induced by tetrabenazine (100 and 200 mg/kg), but showed no effect on that in mice treated with
