“…The different intensity peaks in the range of 1570 to 1230 cm −1 were assigned to the alkenes and methyl groups [ 42 ]. Furthermore, the large peaks situated in the region 1164–1042 cm −1 (1140 and 1091 cm −1 for CE; 1169 and 1071 cm −1 for VE, 1073 and 1048 cm −1 for ME, 1167 and 1076 cm −1 for LE) emphasize the presence of ν(C-O-C) stretch vibration and ν(C-O) stretch vibration from flavonoids [ 44 , 50 , 51 ]. The highest intensity was found in hemp plant extract ( Cannabis sativa L.).…”

In this study, we aim to obtain biomaterials with antibacterial properties by combining poly(vinyl alcohol) with the extracts obtained from various selected plants from Romania. Natural herbal extracts of freshly picked flowers of the lavender plant (Lavandula angustifolia) and leaves of the peppermint plant (Mentha piperita), hemp plant (Cannabis sativa L.), verbena plant (Verbena officinalis) and sage plant (Salvia officinalis folium) were selected after an intensive analyzing of diverse medicinal plants often used as antibacterial and healing agents from the country flora. The plant extracts were characterized by different methods such as totals of phenols and flavonoids content and UV-is spectroscopy. The highest amounts of the total phenolic and flavonoid contents, respectively, were recorded for Salvia officinalis. Moreover, the obtained films of poly(vinyl alcohol) (PVA) loaded with plant extracts were studied concerning the surface properties and their antibacterial or cytotoxicity activity. The Attenuated Total Reflection Fourier Transform Infrared analysis described the successfully incorporation of each plant extract in the poly(vinyl alcohol) matrix, while the profilometry demonstrated the enhanced surface properties. The results showed that the plant extracts conferred significant antibacterial effects to films toward Staphylococcus aureus and Escherichia coli and are not toxic against fibroblastic cells from the rabbit.

“…The absorption bands at around 280 nm and 330 nm could be caused mostly by p-p* as well as n-p* electronic transitions of conjugated systems including carboxylic or carbonyl groups and aromatic rings. 20 The UV spectra had an obvious absorption in the wavelength range of 260-340 nm. This might be due to the presence of high amounts of hesperidin, nobiletin and tangeretin, which were the major secondary metabolites of CRP.…”

“…Peppermint oil was investigated in several studies, employing GC-MS and other techniques [36][37][38][39][40][41][42][43][44]. The main components of this essential oil are menthol and menthone, analyzed using a sensitive gas chromatographic method with flame ionization detector (GC-FID) and GC-MS [38].…”

Essential oils have a vast number of applications in different areas of our daily life. Detailed chiral analysis and structural characterization of their constituents remains an important subject in analytical chemistry. Here, we report on a broadband rotational spectroscopy study of peppermint oil in the frequency range 2–8 GHz. We focus on an unambiguous determination of the excess enantiomers of the oil constituents menthone and isomenthone in the oil by applying chirality-sensitive rotational spectroscopy, the so-called microwave three-wave mixing (M3WM) technique. Additionally, a new menthol conformer, not previously characterized, was experimentally observed, and the gas-phase structures of the two conformers of menthol and menthone were determined experimentally based on the assignment of their 13C-isotopologues in natural abundance.
