2D and 3D DOSY 1H NMR, a useful tool for analysis of complex mixtures: Application to herbal drugs or dietary supplements for erectile dysfunction

Green Synthesis and Characterization of Silver Nanoparticles from Crocus Mathewii; A Disremembered Turkish Flowering Plant

“…Over the past few decades, the use of plants with different applications in medicine and industry has been growing increasingly in the world. In recent years, many environmentally friendly methods have been employed in the synthesis of nanoparticles [27] . The biological methods for AgNPs synthesis using bacteria, fungi, proteins, polypeptides, nucleic acids and plant extracts are simple, nontoxic, affordable and environmentally friendly.…”

Phytochemical Techniques in Complex Botanicals. The XXI Century Analytical Challenge

“…NMR has been proposed as the possible tool in natural products fingerprint and its use reported on foods and medicinal drugs [17][18][19], including the analysis of adulteration or food supplements spiked with synthetic products, when a single simple HPTLC plate can be sufficient [17][18][19][20][21][22][23]. The main problem to face is that also using a spectrometer of high resolution, the possibility of peaks overlapping remains very high.…”
