Thin-Layer Chromatography in Plant Sciences
Published in Bernard Fried, Joseph Sherma, Practical Thin-Layer Chromatography, 2017
(-) Hyoscyamine (or atropine) is the main alkaloid present in Atropa belladonna, Hyoscyamus niger, and Datura stramonium. The TLC differentiation of these drugs is based on the hyoscyamine/scopolamine ratio, and to a limited extent on the contents of the minor alkaloids. For identification and determination of alkaloid content, the European Pharmacopoeia3 describes a TLC technique on silica gel with a solvent system of acetone–water-ammonia (90:7:3); good results were also obtained with the eluent toluene–ethyl acetate–diethylamine (70:20:10).3

Atropa belladonna is a perennial herb belonging to the Solanaceae family and has a very intensive source of tropane alkaloids. This plant includes tropane alkaloids, atropine, hyoscyamine, scopolamine and anisodamine. Atropine is the important chemical of this plant and is mostly found in its leaves and black fruits. The leaves, fruits, stems and roots of this plant have been used in the treatment of many diseases such as joint pain, muscle spasms, brain, eye and acute inflammation, scarlatina, pancreatitis and neurological disorders [10,39]. In addition, atropa belladonna is included in over-the-counter medications that are not approved by the FDA for human use and it is used as a sedative to stop spasms such as cough, cold, asthma, whooping cough, bronchitis, Parkinson’s disease (PD), neuralgia, and rheumatism [40]. As a result of chemical studies, it has been revealed that these plants also have strong antioxidant and anti-cancer properties [41]. Considering the enormous medicinal significance of atropa belladonna, AgNPs have been produced by green synthesis using its extract and successful studies have been conducted on their therapeutic potential [10,42]. Many active ingredients are found in atropa belladonna play an important role as reducing and covering agents. The current study aims to reveal the antibacterial and cytotoxic properties of biodegradable PCL nanofibers doped with AgNPs biosynthesized using atropa belladonna extract, which has therapeutic potential.

Brugmansia arborea is commonly known in Mexico as Floripondio, it is a native plant of South America and it belongs to the Solanaceae family (19). This family is known for producing alkaloids, tropane particularly, which is widely used in traditional medicine due to its anticholinergic properties (20). Figure 1 shows some of the chemical compounds that have been reported for B. arborea, which are: hyoscyamine (I), anisodamine (II) and scopolamine (III); this last compound is considered of great commercial value due to its pharmacological activity and minor side effects (21). Some heteroatoms such as N and O, as well as the presence of π-electrons in carbon–carbon double bonds in the chemical compounds of B. arborea, make it a potential corrosion inhibitor. Therefore, in the present work, extract of B. arborea with acetone, hexane and methanol was tested as corrosion inhibitor of 1018 steel in acid media.
