Banana Flower Nectar - Mediated Synthesis of Silver Nanoparticles

Abstract

Worldwide, the banana is the most famous fruit on the market. All parts of the plant have been used over the years in medicine and the curative properties of the banana are well known. No reports about the study of the nectar of banana flowers could be find, except those on extracts from different parts of the plant, this being the reason of starting synthesis of silver nanoparticles (AgNPs) from the banana flower's nectar. Because conventional methods for producing NPs are expensive, toxic and nonorganic in this study it was used natural sources for NPs synthesis (green synthesis). The AgNPs were characterized by UV-Vis spectrophotometry, optical microscopy (OM), scanning electron microscopy (SEM), Fourier Transform Infrared (FTIR) and Raman spectroscopies.

Physical Characterization of Latex from <i>Artocarpus heterophyllus </i>Lam. (Jackfruit) and Four Related <i>Artocarpus </i>spp.

“…Notably, the latex samples come from a natural source inferring a natural type of resin and it is comparable with the absorption bands of terpenoid resin. The spectra of terpenoid resin [36] in Table 2 served as a reference which showed that Artocarpus species latex share common peaks such as 2930-2958 cm -1 C-H stretches, 1725-1750 cm -1 esters [37], 1695-1715 cm -1 carbonyl bands, 1448-1467 cm -1 aromatic ring stretch, 1382-1387 cm -1 C-H bending of methyl and Methylene groups, 1028-1038 cm -1 Acid resins, and 887-897 cm -1 C-C vibrations [37,38,39].…”

Adsorption efficiency of banana blossom peels (musa acuminata colla) adsorbent for chromium (VI) removal

“…2 shows the FTIR spectra of banana blossom peels adsorbent. The existence of significant hydroxyl (O-H) stretching vibration of cellulose molecules is related to the broad peak that appeared in the region of 3500 cm À1 to 3300 cm À1 [21][22][23][24]. Next, peak at 2920 cm À1 is characteristic of C-H stretching.…”

Green synthesis of silver nanoparticles using banana flower extract, and their antibacterial activity

“…These phytochemicals possess diverse phytochemical properties such as antioxidation, antibacterial, anticancer, antidiabetic, and anti-inflammatory action (Jamuna and Nandini, 2014;Sitthiya et al, 2018). Experiments have shown that the polyphenolic compounds present in banana flowers could act as both reducing and capping agents for the synthesis of AgNPs (Stirbescu et al, 2019). The preparation of AgNPs from banana flower extract can not only reduce the preparation cost, but also maximise the utilisation of agricultural resources.…”
