BACKGROUND: Lagerstroemia speciosa (L.) Pers. has medicinal importance. Bioactive phytochemicals isolated from different parts of L. speciosa, have revealed hypoglycemic, antibacterial, anti-inflammatory, antioxidant and hepato protective properties. Despite one report from Philippines detailing the use of L. speciosa as curative for fever and as well as diuretic, there is no experimental evidence about the hepatoprotective activity of the flower extracts. METHODS: Several spectroscopic methods, including GC-MS, were used to characterize phytochemicals present in the petal extract of L...

BACKGROUND: New combinations of divergent genomes can give rise to novel genetic functions in resulting hybrid progeny. Such functions may yield opportunities for ecological divergence, contributing ultimately to reproductive isolation and evolutionary longevity of nascent hybrid lineages. In plants, the degree to which transgressive genotypes contribute to floral novelty remains a question of key interest. Here, we generated an F1 hybrid plant between the red-flowered Ruellia elegans and yellow flowered R...

Two cases of fatalities are reported of which the recreational use of Mitragyna speciosa ("kratom") could be confirmed. One of these cases presents with one of the highest postmortem mitragynine concentrations published to date. Our results show that even extremely high mitragynine blood concentrations following the consumption of kratom do not necessarily have to be the direct cause of death in such fatalities as a result of an acute overdose. The two cases are compared with regard to the differences in mitragynine concentrations detected and the role of mitragynine in the death of the subjects...

Synthesis of metal oxide nanoparticles using novel methodologies always attracts great importance in research. The use of plant extract to synthesize nano-particle has been considered as one of the eco-friendly methods. This paper describes the biosynthetic route of preparation of zinc oxide nanoparticles (ZnO NPs) from the Lagerstroemia speciosa leaf extract. This approach appears to be low-cost preparation and alternative method to conventional methods. Highly stable and hexagonal phase ZnO NPs with average particle size of 40nm were synthesized and characterized by UV-Vis absorption spectroscopy (surface Plasmon resonance), Fourier transform infrared spectroscopy (surface functionalities), X-ray Diffraction analysis (crystallinity), TEM and SEM (size and morphology), Energy Dispersive X-ray spectroscopy (elemental composition), Thermogravimetric analysis (weight loss) and Zeta potential (stability)...
