“…Due to its genetic variation, wide geographical distribution and exposure to different soil and weather conditions, and distinct seasons of collection, L. alba can produce EOs with different chemical composition, which expresses the occurrence of distinct chemotypes (Pascual et al, 2001;Hennebelle et al, 2008;Maffei et al, 2011;Teles et al, 2012). There are numerous chemotypes of L. alba in Brazil, such as: citral, linalool, ß-caryophyllene, tagetenone, limonene, carvone, myrcene, γ-terpinene, camphor-1,8-cineole and estragole, which produce different pharmacological effects (Oliveira et al, 2006;Hennebelle et al, 2008;Vale et al 2012;Viccini et al, 2014). Thus, the distinct composition of same EO may result in different physiological and pharmacological effects during anesthesia.…”

The aim of this study was to evaluate if Lippia alba has different chemotypes according to the chemical composition of the essential oil (EO) considering collection site, and if the EO may have different effects on blood and plasma parameters in silver catfish, Rhamdia quelen, during and immediately after anesthesia. The citral (EO-C) and linalool (EO-L) chemotypes were identified, and both presented similar anesthetic effects for silver catfish. Fish were exposed to two concentrations of each EO, which induced slow and fast anesthesia (100 and 300 µL L -1 , respectively). Blood ions did not change at any time of anesthesia induction and recovery and, therefore, the electrolyte balance was not altered. Blood gases oscillated through all exposure and recovery times, but there was an increase in pO 2 after 10 min recovery in fish anesthetized with EO-C. Glucose increased in fish exposed to both EOs when compared with the control group. Overall, exposure to both EOs (except 100 µL L -1 EO-L at most times) reduced plasma cortisol levels compared to the control and/or ethanol groups. However, as plasma creatinine levels in fish anesthetized with EO-C were higher than control fish, the use of EO-L is preferable.Keywords: Blood gas, Cortisol, Glucose, Plasma ions, Silver Catfish.O objetivo deste estudo foi avaliar se Lippia alba apresenta diferentes quimiotipos de acordo com a composição química do óleo essencial (OE), considerando local de coleta e se o OE causa diferentes efeitos nos parâmetros sanguíneos e plasmáticos em jundiá, Rhamdia quelen, durante e imediatamente após a anestesia. Os quimiotipos citral (OE-C) e linalol (OE-L) foram identificados e ambos apresentaram efeito anestésico semelhante para jundiá. Os peixes foram expostos a duas concentrações de cada OE, que induziram anestesia lenta e rápida (100 e 300 mL L -1 , respectivamente). Íons sanguíneos não se alteraram em nenhum tempo e consequentemente, o equilíbrio eletrolítico não foi alterado. Os gases sanguíneos oscilaram durante todo tempo de exposição e recuperação, mas houve aumento na pO 2 após 10 min de recuperação em peixes anestesiados com OE-C. Níveis sanguíneos de glicose aumentaram nos peixes expostos a ambos OEs quando comparados com o grupo controle. De um modo geral, a exposição a ambos OEs (exceto 100 µL L -1 OE-L na maioria dos tempos) reduziu o cortisol plasmático comparado aos grupos controle e etanol. No entanto, como os níveis de creatinina plasmática em peixes anestesiados com OE-C foram maiores que nos peixes controle, é preferível o uso do OE-L.

“…As Viccini et al. () reported, triploids are linalool producers, while diploid and tetraploid accessions produce citral (geranial and neral). Only two tetraploid samples (4xN26 and 4xN61) and the hexaploid accessions showed carvona as the major compound (Appendix S1).…”

“…Lippia alba not only exhibits polyploidy, but also has other features that make the species an important model for study. It possesses extensive phenotypic and chemical variation (Reis et al., ; Viccini et al., ; Timóteo et al., ) and is widely used in folk medicine (Hennebelle et al., ). Viccini et al.…”

Premise Plant genomes vary in size and complexity due in part to polyploidization. Latitudinal analyses of polyploidy are biased toward floras of temperate regions, with much less research done in the tropics. Lippia alba has been described as a tropical polyploid complex with diploid, triploid, tetraploid, and hexaploid accessions. However, no data regarding relationships among the ploidal levels and their origins have been reported. Our goals are to clarify the relationships among accessions of Lippia alba and the origins of each ploidal level. Methods We investigated 98 samples representing all five geographical regions of Brazil and all ploidal levels using microsatellite (SSR) allelic variation and DNA sequences of ITS and trnL‐F. Nine morphological structures were analyzed from 33 herbarium samples, and the chemical compounds of 78 accessions were analyzed by GC–MS. Results Genetic distance analysis, the alignment block pattern, as well as RAxML and Bayesian trees showed that accessions grouped by ploidal level. The triploids form a well‐defined group that originated from a single group of diploids. The tetraploids and hexaploid grouped together in SSR and trnL‐F analyses. The recovered groups agree with chemical data and morphology. Conclusions The accessions grouped by ploidal level. Only one origin of triploids from a single group of diploids was observed. The tetraploid origin is uncertain; however, it appears to have contributed to the origin of the hexaploid. This framework reveals linkages among the ploidal levels, providing new insights into the evolution of a polyploid complex of tropical plants.
