TLDR
In an effort to study plants of the Rubiaceae from Panama, 299 herbarium samples, representing 133 species, were subjected to alkaloid screening, for the first time that 102 (94%) and 52 (90%) species are reported as alkaloids and indole alkaloidal bearing, respectively.Abstract:
In an effort to study plants of the Rubiaceae from Panama, 299 herbarium samples, representing 133 species, were subjected to alkaloid screening. From this total, 234 samples (78%) afforded a positive test for alkaloids, and 99 samples (33%) gave a positive reaction for indole alkaloids; 109 species (82%) contain alkaloids and 58 (44%) produce indole alkaloids. This is the first time that 102 (94%) and 52 (90%) species are reported as alkaloid and indole alkaloid bearing, respectively. The results of 10 out of 15 species, that is 67%, corroborate earlier studies. The richest indole alkaloid species were: Hamelia patens, Hamelia xerocarpa, Hoffmannia morii, Hoffmannia unguis-canceris, Deppea grandiflora, Elaeagia nitidifolia, Rondeletia secunda, Simira maxonii, Uncaria tomentosa, Gonzalagunia rosea, Isertia haenkeana, Isertia laevis, Posoqueria latifolia and Cinchona pubescens.read more

Rapid diversification associated with ecological specialization in Neotropical Adelpha butterflies
Emily R. Ebel,Jeffrey M. DaCosta,Michael D. Sorenson,Ryan I. Hill,Adriana D. Briscoe,Keith R. Willmott,Sean P. Mullen +6 more
TL;DR: The hypothesis that evolutionary innovations in both larvae and adults have permitted the colonization of novel host plants and fuelled adaptive diversification within this large butterfly radiation is supported.

Ethnopharmacology of Q'eqchi' Maya antiepileptic and anxiolytic plants: effects on the GABAergic system.

TL;DR: Clearly, Q'eqchi' traditional knowledge of antiepileptic and anxiolytic plants is associated with the use of pharmacologically active plants, and it is suggested that the mechanism of action for some traditionally used plants may be mediated through the GABAergic system.

Frequency dependence shapes the adaptive landscape of imperfect Batesian mimicry

TL;DR: The results provide compelling experimental evidence that imperfect Batesian mimicry is frequency-dependent on the relative abundance of models and mimics in natural populations, and contribute to the growing body of evidence that complex dynamics, such as seasonality or the availability of alternative prey, influence the evolution of mimetic traits.

Acute and subacute toxicity of the aqueous extract of Alibertia edulis (Rich.) A. Rich. ex DC. in rats.

TL;DR: All doses tested can be considered safe in rats and the LD50 is higher than 2000mg/kg, therefore, further assessments are required in order to proceed to clinical studies in humans.
Journal ArticleDOI
Complex dynamics underlie the evolution of imperfect wing pattern convergence in butterflies
TL;DR: Although these data reveal the first evidence for protection from avian predators by the supposed toxic, Rubiaceae‐feeding Adelpha species, it is concluded that imprecise mimetic patterns have high costs for Batesian mimics in the tropics.

Die Alkaloide von Uncaria tomentosa und ihre Phagozytose-steigernde Wirkung.
TL;DR: With the exception of mitraphyllin and rynchophyllin all alkaloids showed a pronounced enhancement effect on phagozytosis, determined in two IN VITRO tests and the IN VIVO-carbon clearance test.

Production of anti-tumor-promoting iridoid glucosides in Genipa americana and its cell cultures.
TL;DR: The Genipa americana plant contains geniposide and Geniposidic acid in the fruits and genipOSidic Acid in the leaves and on callus induction, the plant produces tarennoside, genipoic acid, and gardenoside in high levels.
