“…The host plant Brunfelsia uniflora is a Neotropical shrub used as an ornamental (Plowman, 1979) and medicinal plant (Schultes, 1976). This genus of plants is known to contain brunfelsamidine (Lloyd et al, 1985), scopoletine (Mors & Ribeiro, 1957) and calistegines (Bekkouche et al, 2001).…”

“…The present study described for the first time the chromatographic profiles of extracts from leaves of B. uniflora. Alkaloids such as scopoletin have been reported in most species of the genus Brunfelsia (MORS & ROBEIRO, 1957), and the calystegine alkaloids were identified in B. nitida (BEKKOUCHE et al, 2001). A variety of flavonoids have been isolated from species belonging to the Solanaceae family including Browallia grandiflora, Chamaesara chasordida, Nicotiana tabacum, Petunia urfina, and Salpiglossis sinuata (WOLLENWEBER & DORR, 1995).…”

In Brazil, at least 16 poisonous plant species can affect the central nervous system of livestock. Recently in the state of Piauí, Northeastern Brazil, Brunfelsia uniflora was reported as a cause of nervous signs in donkeys, cattle, and small ruminants. In order to assess the toxicity of B. uniflora extracts, 20 Swiss mice were distributed into four groups (n=5) receiving by gavage alkaloids, flavonoids, saponins, or saline (control group). After administration of the extracts in a single dose (5g kg-1), all mice were observed daily for clinical signs. Mice that received the extracts showed moderate to severe clinical signs, including piloerection, vocalization, and seizures. All mice dosed with saponins died between 10 and 20min after administration. Serum biochemical evaluation of animals that received saponins revealed slight increases in total protein levels and decreased magnesium and chlorite levels. In conclusion, saponins of B. uniflora leaves induced acute toxic neurological effects and death in mice.

“…Besides, the contents of glycerol-3P, galactinol and erythritol also varied significantly among the RILs. Remarkably, the levels of calystegine B2, an alkaloid present in a wide range of Solanaceae species (Asano et al 1997;Bekkouche et al 2001), displayed a variation between four and 13-fold. Evaluating the proportion of every metabolite category varying in the RIL population (and also in the F1 hybrid) with respect to the cultivated parent (Fig.…”

Metabolic analyses of interspecific tomato recombinant inbred lines for fruit quality improvement

Elucidating the determinants of tomato nutritional value and fruit quality to introduce improved varieties on the international market represents a major challenge for crop biotechnology. Different strategies can be undertaken to exploit the natural variability of Solanum to re-incorporate lost allelic diversity into commercial varieties. One of them is the characterization of selected germplasm for breeding programs. To achieve this goal, 18 RILs (S. lycopersicum 9 S. pimpinellifolium) were comprehensively phenotyped for fruit polar metabolites and quality associated traits. Metabolites were quantified by GC-MS and 1 H NMR. Integrative analyses by neuronal clustering and network construction revealed that fruit properties are strongly associated with the metabolites aspartate, serine, glutamate and 2-oxoglutarate. Shelf life and firmness appeared to be linked to malate content. By a comparative analysis of the whole data set, ten RILs presented higher number of traits with positive effect than the S. lycopersicum 9 S. pimpinellifolium hybrid. Thus, these lines can be proposed as promising candidates for breeding programs aimed to improve fruit quality.
