TL;DR: The purpose of this review is to provide knowledge about the type of chestnut by-products produced, the studies concerning its chemical composition and biological activity, and also to discuss other possible applications of these materials.

TL;DR: There are indications of usnic acid being a potentially interesting candidate for such activities as anti-inflammatory, analgesic, healing, antioxidant, antimicrobial, antiprotozoal, antiviral, larvicidal and UV protection, however, some studies reported the liver toxicity and contact allergy.

TL;DR: Anti-quorum sensing activity of the diterpene phytol was evaluated in vitro for the first time and may inspire design of medical foods targeting P. aeruginosa twitching and flagella motility.

TL;DR: The significant linear correlations between total phenolic content and antiradical activity and between total phenotype content and reducing power were observed, and the total flavonoids content significantly correlated with antiracetic activity and reducingPower.

TL;DR: The significance of this study is that saponin absorption peaks are directly detectable in crude aqueous and 95% ethanol extracts of soapnuts powder using FTIR spectroscopy, thereby eliminating the need of further expensive and exhaustive purification steps.

TL;DR: The results of data analysis on the chemical, pharmacological characteristics of LLF support the view that this species has many therapeutic properties and indicate its potential as an effective herbal remedy.

TL;DR: Dear Editor,Curcumin is a polyphenolic compound with a multitude of beneficial actions for cardiometric health.

TL;DR: This study indicates the effectiveness of abiotic elicitation on bacoside production in in vitro shoot cultures of this medicinally important herb known for its memory-enhancing properties.

TL;DR: From the results, it was observed that the chitins isolated with the new method and the commercial chitin had almost the same physicochemical properties.

TL;DR: It could be suggested that the active compounds contained in Moro Juice have a synergistic effect on fat accumulation in humans and Moro juice extract can be used in weight management and in the prevention of human obesity.

TL;DR: The present investigation provided significant information about antifungal activity and compounds isolated from two different strains of T. harzianum obtained from twoDifferent Himalayan locations.

TL;DR: All EOs showed low activities against the bacterial strains tested, whereas the C. zehntneri oil and its main constituent estragole exhibited an appreciable antifungal activity against C. parapsilosis.

TL;DR: This review focuses on the naturally occurring PEC derivatives, their sources, physical and spectral data, as well as biological activities.

TL;DR: Berberine inhibited the synthesis of proteins associated with the growth and cleavage of bacteria and then blocked the division and development of bacteria, which ultimately induced cytoplasm pyknosis and bacterial death.

TL;DR: The molar concentration of the main metabolites constituent the juice of PGI Interdonato Lemon of Messina in comparison with that of the not-PGI Interdonatos Lemon of Turkey is determined by means of HR-MAS NMR spectroscopy.

TL;DR: In all tests, only baicalein – the aglycone with three adjacent hydroxyl groups – exhibited consistent antioxidant effect, and wogonin protected linoleic acid against oxidation.

TL;DR: Among the 27 studied compounds, hesperidin, rutin, hyperoside and quinic, malic, gallic and tannic acids were found to be the most abundant compounds in the two Euphorbia species.

TL;DR: The evaluation of total phenolic content and total flavonoid content revealed high antioxidant potential of the seeds and fruits and the free radical-scavenging ability of the aqueous extracts indicated the seeds to have better DPPH- scavenging activity than fruits.

TL;DR: Results revealed that alkaline pretreatment of wheat straw for optimum steaming period has strong effect on substrate, indicating that the above-mentioned pretreatment conditions create accessible areas for enzymatic hydrolysis.

TL;DR: The results show that the essential oil yield of the 10 biotypes is affected by the environmental characteristics of the sampling sites while the chemical composition is linked to the genetic characteristics of different biotypes.

TL;DR: This research shows that both fatty acid and tocopherol contents differ significantly among the safflowers.

TL;DR: Local herbs might have a potential role as anticancer natural medicines in addition to their high antioxidant activities due to the presence of different phenolics in their aqueous tea extracts.

TL;DR: The essential oils from the leaves of Eucalyptus spp.

TL;DR: The oil showed activity against all tested strains with minimal inhibitory concentration values ranging between 1% and 4%.

TL;DR: Composition of tocochromanols in kernels recovered from 16 different apricot varieties (Prunus armeniaca L.) was studied and the ratio between individual tocopherol homologues α:γ:δ was nearly constant in all varieties and amounted to approximately 2:39:1.

TL;DR: This work established a rapid and efficient model for screening HupA-producing endophytic fungal strains from the Chinese folk herb, Huperzia serrata, and reported the first report of P. tenuis as a H upA- producing endophyte isolated from Huperziaceae.

TL;DR: This study is the first to perform GC/MS analysis of C. linifolia essential oil growing in Egypt, and the results encourage further investigation of the two oils as antimicrobial and insecticidal agents of natural origin.

TL;DR: The essential oil and its main compounds exhibited a potent NO-scavenging effect and inhibited the expression of inducible NO synthase and exhibited a higher activity in each antioxidant system with a special attention for β-carotene bleaching test.

TL;DR: OB extracts not only improve taste but also have certain anticancer activity against diverse cancer cells due to the presence of compounds such as rosmarinic acid, chicoric acid and caftaric acid, which represents a potent source of anticancer materials.

TL;DR: Comparison of volatile profiles indicated a variation in fragrance contents and types emitted from these four jasmine flowers, which shall help in elucidating the enzymes and genes of fragrance biosynthesis in jasmines and in aiming to create flowers with improved scent quality.
