“…So, in the extract of the leaves collected in the summer season, prominent peaks were observed in the region of 1626 and 1057 cm −1 , while in the winter extract, the peaks were in the region of 1628 and 1072 cm −1 . The presence of peaks in the regions of 1626 and 1628 cm-1 can be attributed to the vibrations of the bonds of the amide functional group I [22,23] or the carbonyl groups (1620-1636 cm −1 ), probably polyphenols [24], while peaks 1057 and 1072 cm −1 indicate C-O-type bonds, such as esters, ethers, alcohols or carboxylic acid [25].…”

The aim of the present study was to evaluate the potential of silver nanoparticle synthesis using extracts from the leaves of Pterodon emarginatus (white sucupira) collected during the summer and winter seasons. Leaves were collected for the production of aqueous extracts, which were added to the aqueous solutions of silver nitrate leading to a final concentration of 1 mM. The reactions were incubated at 75 °C for 150 min and monitored every 30 min by absorption spectroscopy at 425 nm. The samples were complementarily characterized by dynamic light scattering, zeta potential, transmission electron microscopy, atomic force microscopy, MALDI-TOF mass spectrometry, Fourier transform infrared spectroscopy and X-ray diffraction analyses. Both extracts (summer and winter) exhibited a satisfactory reduction of silver ions, capable of inducing the formation of AgNPPe with considerable colloidal stability. The seasons of leaf collection interfered with the synthesis and yield of the AgNPPe, and also with their hydrodynamic diameters and zeta potentials, but the particles showed similar dry sizes (height and diameter), molecular profiles, and crystallinity patterns of the atoms. In sum, the results indicated that some AgNPPe parameters can be tunable by seasonal aspects of the plants and, therefore, such nanomaterials are propitious aiming future evaluation of their applications in several areas.

Background: Asthma is a very common and chronic disease in which there is an inflammation of the lungs. Inflammatory airways and narrowing, spasms, over-secretion of mucus, bronchoconstriction, and eosinophilic airway inflammation are generally seen in the asthmatic condition. Globally, its prevalence is rising constantly. The extracts of Lonicera obovata and Morina longifolia of the Caprifoliaceae family were traditionally used by the Himalayan local people to treat asthmatic and inflammatory conditions. Objectives: The goal of this experimental study was to identify the phytochemicals of the plants through GC-MS. To investigate and compare the anti-asthmatic potential of methanolic whole plant extracts of L. obovata and methanolic root extracts of M. longifolia through in-vivo experiments. Materials and Methods: The anti-asthmatic potential of extracts was determined by the method of leukocytosis and eosinophilia induced by milk in the Swiss albino mice model. Results: Various secondary active phytoconstituents were detected through the GC-MS screening method, some of which have anti-allergic (anti-asthmatic) and antihistaminic properties. The in vivo experiment result showed that in the case of increased leukocyte count, M. longifolia shows better results than L. obovata, and in the case of increased eosinophil count, L. obovata shows better results than M. longifolia to reduce the increased count. Conclusion:The anti-asthmatic potential of plant extracts could be due to the presence of the phytoconstituents like 1-Monolinoleoylglycerol trimethylsilyl ether in the L. obovata extracts and Octadec-9-enoic acid and Cis-vaccenic acid in both L. obovata and M. longifolia extracts. Hence, through the experiments, the unexplored anti-asthmatic properties were revealed and justifies the traditional usage of both plants to treat asthma.

Klebsiella pneumoniae produce many important secondary metabolites with high biological activities. Based on the significance of employing bioactive compounds in pharmacy to produce drugs for the treatment of many diseases, the purification of compounds produced by Klebsiella pneumoniae can be useful.
