Objective: Bougainvillea xbuttiana is widely distributed in Mexico and it used as an analgesic in folk medicine. The aim of this study was to investigate the effect of five ethanolic extracts of Bougainvillea xbuttiana from different colours on cell and to quantify the potential of antioxidant activity, the total phenolic and flavonoids contents, all these in order to find possible sources for ...

Bougainvillea xbuttiana is used as an analgesic in folk medicine in Mexico. The purpose of the present study was to determine the effects of the ethanolic extract from B. xbuttiana on macrophages activities. The phytochemical screening was performed for determine the presence of alkaloids, flavonoids, triterpenes, and saponins. The effects of B. xbuttiana were analyzed using the macrophages act...

Consumption of the edible flowers forms new trend in human nutrition, especially in Bulgaria. Therefore, the determination of bioactive compounds content in their petals presents important tasks for their evaluation as natural source of antioxidants for human diet. In this study the quantity of natural pigments, total phenolic content and total flavonoids content, as well the antioxidant capaci...

Potted bougainvillea `Purple Flower' and `Taipei Red' in four different stages of bract development were sprayed with STS (0.1, 0.5 mM) or NAA (25, 50 ppm) and were moved to lowlight indoor conditions after treatment. The experiment was conducted twice, and the results showed that 0.5 mM STS and NAA (25, 50 ppm) could signi®cantly prolong the longevity of bracts at certain stages in both cultiv...

The present study reports that the flower of Bougainvillea spectabilis Willd. has the potentiality to reduce sodium selenate and synthesize selenium nanoparticles. The exposure of aqueous sodium selenate to the flower broth of B.spectabilis leads to the synthesis of stable selenium nanoparticles within five days. The colour change of the reaction medium from purple to brown colour indicates the...

The 18S rDNA sequences of the six most common European Lymnaeidae species (Mollusca:Gastropoda:Basommatophora) have been obtained by direct PCR cycle sequencing and silver staining methods. The sequence alignment and secondary structures of the 18S rRNA gene of Lymnaea stagnalis, L. auricularia, L. peregra, L. palustris, L. glabra, and L. truncatula are analyzed. This gene proves to be a good m...
