Coumarins are phytochemicals occurring in the plant kingdom, which biosynthesis is induced under various stress factors. They belong to the wide class of specialized metabolites well known for their beneficial properties. Due to their high and wide biological activities, coumarins are important not only for the survival of plants in changing environmental conditions, but are of great importance in the pharmaceutical industry and are an active source for drug development. The identification of coumarins from natural sources has been reported for different plant species including a model plant Arabidopsis thaliana. In our previous work, we demonstrated a presence of naturally occurring intraspecies variation in the concentrations of scopoletin and its glycoside, scopolin, the major coumarins accumulating in Arabidopsis roots. Here, we expanded this work by examining a larger group of 28 Arabidopsis natural populations (called accessions) and by extracting and analysing coumarins from two different types of tissues–roots and leaves. In the current work, by quantifying the coumarin content in plant extracts with ultra-high-performance liquid chromatography coupled with a mass spectrometry analysis (UHPLC-MS), we detected a significant natural variation in the content of simple coumarins like scopoletin, umbelliferone and esculetin together with their glycosides: scopolin, skimmin and esculin, respectively. Increasing our knowledge of coumarin accumulation in Arabidopsis natural populations, might be beneficial for the future discovery of physiological mechanisms of action of various alleles involved in their biosynthesis. A better understanding of biosynthetic pathways of biologically active compounds is the prerequisite step in undertaking a metabolic engineering research.

Marine algae are known to contain a wide variety of bioactive compounds. They are also rich in novel biomolecules and can be explored for the development of drugs to combat lifestyle diseases like cancer, diabetes etc. Red algae are known for their nutraceutical and functional importance. But there are a lot of limitations regarding their availability and in estimating which algal fractions are biologically active. Similarly, the mode of digestion of such compounds in human body is not yet properly traced. In this juncture, the present study was aimed to evaluate the phytochemical screening of the methanolic extract of the red alga, Gracilaria dura. Methanolic extract of G. dura showed the presence of reducing sugar, flavonoids, glycosides, tannins and terpenoids. Further, the HPLC analysis was attempted to fractionate the polyphenolics. Various phenolic acids such as of gallic acid, vanillic acid, sinapic acid, p-coumaric acid, hydroxybenzoic, phloroglucinol, catechol and cinnamic acid were identified. Subsequently, the methanolic solvent extract of G. dura was subjected to fourier transform infrared spectroscopy for the analysis of the functional groups. The results based on the spectral data of FTIR revealed the presence of aliphatic constituents containing alkanes, ketones, alkyl halides, hydroxyl groups etc. Thus, the observed finding envisages that methanolic extract of G. dura contained potential bioactive compounds which can be used for analysing the various biological activities.

Abstract Acacia nilotica is an important medicinal plant, found in Africa, Middle East, and Indian subcontinent. Every part of the plant possesses a wide array of biologically-active and therapeutically important compounds and have been used in traditional-system of medicine. We reported the antileishmanial activity of Acacia nilotica (A. nilotica) bark methanolic extract through in vitro assays and dissected the mechanism of its action through in silico studies. Bark methanolic extract exhibited anti-promastigote and anti-amastigote potency with IC50 value of 19.6 + 0.9037 µg/ml and 77.52 + 5.167 µg/ml respectively in time and dose dependent manner. It showed very low cytotoxicity having CC50 value of 432.7 + 7.71 µg/ml on human-macrophage cell line, THP-1. The major constituents identified by GC-MS analysis are 13-docosenoic acid (34.06%), lupeol(20.15 %), 9,12-octadecadienoic acid (9.92 %) and 6-octadecanoic acid (8.43 %) bind effectively with the potential drug-targets of Leishmania donovani (L. donovani ) including sterol 24-c-methytransferase (SMT), trypanothione reductase (TR), pteridine reductase (PTR1) and adenine phosphorybosyl transferase (APRT); suggest the possible mechanism of its antileishmanial action. The highest affinity with all these targets was shown by lupeol. The pharmacokinetic studies, predicted bioactivity scores and acute toxicity studies of major extract constituents support safe antileishmanial drug candidate. This study proved the antileishmanial potential of bark-methanolic extract A. nilotica and its mechanism of action through the inhibition of potential drug targets of L. donovani.

The repurposing of by-products and the reduction of waste from food processing streams is an ever-increasing area of interest. Brewer’s spent yeast (BSY) is a prevalent by-product of the brewing industry. The spent yeast cells are removed at the end of the bulk fermentation. A small amount of it is used to start the next batch of fermentation; however, the majority of the spent yeast is discarded. This discarded yeast is high in nutrients, in particular proteins, vitamins and minerals, as well as containing functional and biologically active compounds such as polyphenols, antioxidants, β-glucans and mannoproteins. At present, BSY is mainly used in animal feed as a cheap and readily available source of protein. This review explores alternative, value-added applications for brewer’s spent yeast including nutritional ingredients, functional food additives as well as non-food applications. A major challenge in the utilization of BSY in food for human consumption is the high level of RNA. An excess of RNA in the diet can lead to an increase in uric acid in the bloodstream, potentially causing painful health conditions like gout. This issue can be overcome by RNA degradation and removal via additional treatment, namely heat treatment and enzymatic treatment. There is potential for the use of BSY ingredients in various food applications, including meat substitutes, bakery products and savory snacks.

Thousands of polyphenolic compounds have been identified in various plants. Recently, a number of studies showed that beneficial effects of grapes are related to the presence of polyphenols, with multiple biological activities. The aim of this study was to compare the polyphenol profiles as well as biological activities of the seeds of four Tunisia cultivated grape cultivars, syrat, merlot, cabernet sauvignon and carignan. The total phenolic content of seed extracts varied between varieties and seemed to be correlated to the scavenging activity. Preliminary antibacterial results showed a good growth inhibitory activity of syrat cultivar against Staphylococcus epidermidis. To our knowledge, this is the first of such study being performed on this bacterium, known as a leading cause of Tunisian hospital-acquired infections. Gas Chromatography Mass Spectrometry analysis identified 20 polyphenol components, flavonoids being the most abundant in all extracts, followed by phenolic acids, resveratrol, tyrosol, and syringaldehyde. We also noticed a deficiency of three phenolic acid compounds (salicylic acid methyl ester, ferulic acid, Sinapic acid) as well as a flavonoid one (myricetin) in merlot cultivar, which could be responsible for its low antioxidant activity. These results will help in the selective exploitation of the seeds obtained from winemaking wastes, as well as in further pharmacological and/or in vivo investigations.
