The objective of this study was to evaluate the in vitro effects of flavonoid-rich plant extracts (PE) on ruminal fermentation characteristics and methane emission by studying their effectiveness for methanogenesis in the rumen. A fistulated Holstein cow was used as a donor of rumen fluid. The PE (Punica granatum, Betula schmidtii, Ginkgo biloba, Camellia japonica, and Cudrania tricuspidata) kn...

Transcriptome profiles of the red- and white-fleshed apples in an F1 segregating population of Malus sieversii f.Niedzwetzkyana and M.domestica 'Fuji' were generated using the next-generation high-throughput RNA sequencing (RNA-Seq) technology and compared. A total of 114 differentially expressed genes (DEGs) were obtained, of which 88 were up-regulated and 26 were down-regulated in red-fleshed...

in this study, caffeic acid (ca) and its three derivatives including 3-caffeoylquinic acid (3-cqa, neochlorogenic acid), 4-caffeoylquinic acid (4-cqa, cryptochlorogenic acid), and 5-caffeoylquinic acid (5-cqa, chlorogenic acid) were identified in bupleurum chinense aerial parts using reverse-phase high-performance liquid chromatography (rp-hplc) with photodiode array (pda) detector, reference c...

background scrophularia striata (scrophulariaceae family) is an herbaceous plant that is traditionally used for treatment of microbial infections. objectives antimicrobial and antioxidant activity of different extracts (methanolic, ethanolic, aqueous and ethyl acetate) from s. striata aerial parts was evaluated. materials and methods the antimicrobial activity of different extracts from s. stri...

The present study was designed to explore the flavonoid contents and the radical scavenging activities of 50% ethanol extracts of leaves, stems, rachis and roots of Dryopteris erythrosora. The total flavonoid contents in various parts were determined as: stems > roots > rachis > leaves. All extracts from different parts of D. erythrosora showed strong bioactivities. The DPPH free radical scaven...

based on the valuable antioxidant activity of citrus fruits, in present study the effect of ‎rootstock and the type of tissue on some fruit quality parameters including phenol, ‎flavonoid, antioxidant and the content of hesperidin and naringin of orange and mandarin ‎was studied. the experiment was conducted as a factorial design based on complete ‎randomized blocks with four replications. resu...

Antioxidant activity was evaluated in six Indian cultivars of lentil (Lens culanaris L.) viz. L-4076, L-4594, L-4147, DPL 15, DPL 62, and IPL 406. Three solvents, 70% ethanol, 100% methanol and 80% acetone, were used for preparation of seed extract. The seed extract was tested for total phenolic content, total flavonoid content and antioxidant activity by FRAP assay. The results showed that val...

High flavonoid consumption can improve vascular health. Exploring flavonoid–metabolome relationships in population-based settings is challenging, as: (i) there are numerous confounders of the flavonoid–metabolome relationship; and (ii) the set of dependent metabolite variables are inter-related, highly variable and multidimensional. The Metabolite Fingerprint Score has been developed as a means...

the antioxidant and cytotoxic properties of four major parts of methanolic extracts of tephrosia purpurea including leaves, root, stem and seed were investigated and compared. in vitro antioxidant activity of t. purpurea extracts was evaluated using 1,1-diphenyl-2-picrylhydrazyl (dpph), ferric reducing antioxidant power (frap), reducing power assay and antihemolytic assay. in vitro cytotoxic ef...
