Phenolic Compounds Quantification, Antioxidant and Antibacterial Activities of Different Parts of Urtica dioica and Chenopodium murale

The aim of our study was to evaluate the dependence of the accumulation of phenolic compounds (soluble phenolic compounds and tannins) and ascorbic acid in different parts of three medicinal plants: Bidens tripartita, Urtica dioica and Chenopodium album on the place of growth. The plants were collected from three regions of Tatarstan (Vysokogorsky, Laishevsky and Spassky region. The results showed that the accumulation of these substances in the studied plants differs in different parts of the plants, depending on the place of growth. B. tripartita is the richest in the studied substances. Vysokogorsky and Spassky regions turned out to be areas with the best plant raw materials.

Senna Alata

This present work is aimed at determining the chemical components in Senna alata (L.) Roxb. (Fabales: Fabaceae), that contains a large array of phenolic compounds which make it useful as antifungal and antibacterial. Despite a notable success in the recent researches, yet, the quantification of the chemical components has not been actually specified. There is a claim by local people that S. alata can cure fungi and bacteria related diseases. Therefore, there is a need to ascertain this claim by examining the bioactive components present in the plant. The Gas Chromatography (GC) analysis was performed using a Clarus 500 Perkin Elmer gas chromatography equipped with an Elite-5 capillary column with the addition of an absolute alcohol. The antimicrobial analysis was carried out using Agar Disc Diffusion Method. In the GC chromatogram, four prominent peaks were observed in leaf chromatogram, three peaks in flower chromatogram and five peaks in fruit chromatogram, respectively. The flower contained the highest amount of cinnamic acid (52.91%) and the fruit contained the least (17.03%). The presence of some bioactive metabolites could be responsible for the observed antifungal and antibacterial activities on the susceptible organisms studied. It could be concluded that this plant is natural sources of antimicrobial substances of high importance and are useful in chemotherapy.

Sweet Cherry Cultivars

Every year, large quantities of stems and pits are generated during sweet cherry processing, without any substantial use. Although stems are widely recognized by traditional medicine, detailed and feasible information about their bioactive composition or biological value is still scarce, as well as the characterization of kernels. Therefore, we conducted a study in which bioactivity potential of extracts from stems and kernels of four sweet cherry cultivars (Early Bigi (grown under net cover (C) and without net cover (NC)), Burlat, Lapins, and Van) were examined. The assays included antioxidant (by 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic) acid (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH) and β-carotene-linoleic acid bleaching assays), and antibacterial activities against important Gram negative and Gram positive bacterial human isolates. Profile and individual phenolic composition of each extract were determined by High-performance liquid chromatography (HPLC) analysis. Extracts from stems of cv. Lapins and kernels of Early Bigi NC presented high levels of total phenolics, flavonoids, ortho-diphenols and saponins. Excepting for cv. Early Bigi NC, major phenolic compounds identified in stems and kernels were sakuranetin and catechin, respectively. In cv. Early Bigi NC the most abundant compounds were ellagic acid for stems and protocatechuic acid for kernels. In all extracts, antioxidant activities showed a positive correlation with the increments in phenolic compounds. Antimicrobial activity assays showed that only stem’s extracts were capable of inhibiting the growth of Gram positive isolates. This new data is intended to provide new possibilities of valorization of these by-products and their valuable properties.

Herbs derived from Taraxacum genus have been used as traditional medicines and food supplements in China for hundreds of years. Taraxacum mongolicum is a famous traditional Chinese medicine derived from Taraxacum genus for the treatment of inflammatory disorders and viral infectious diseases. In the present study, the bioactive phenolic chemical profiles and antioxidant activities of flowers, leaves, and roots of Taraxacum mongolicum were investigated. Firstly, a high performance liquid chromatography method combined with segmental monitoring strategy was employed to simultaneously determine six bioactive phenolic compounds in Taraxacum mongolicum samples. Moreover, multivariate statistical analysis, including hierarchical clustering analysis, principal component analysis, and partial least squares discriminant analysis were performed to compare and discriminate different parts of Taraxacum mongolicum based on the quantitative data. The results showed that three phenolic compounds, caftaric acid, caffeic acid, and luteolin, could be regarded as chemical markers for the differences of flowers, leaves, and roots of Taraxacum mongolicum. In parallel, total phenolic contents, total flavonoid contents and antioxidant activities of different parts of Taraxacum mongolicum were also evaluated and compared. It is clear that Taraxacum mongolicum had antioxidant properties, and the antioxidant capacities of different parts of Taraxacum mongolicum in three antioxidant assays showed a similar tendency: Flowers ≈ leaves > roots, which revealed a positive relationship with their total phenolic and flavonoid contents. Furthermore, to find the potential antioxidant components of Taraxacum mongolicum, the latent relationships of the six bioactive phenolic compounds and antioxidant activities of Taraxacum mongolicum were investigated by Pearson correlation analysis. The results indicated caftaric acid and caffeic acid could be the potential antioxidant ingredients of Taraxacum mongolicum. The present work may facilitate better understanding of differences of bioactive phenolic constituents and antioxidant activities of different parts of Taraxacum mongolicum and provide useful information for utilization of this herbal medicine.
