Many pine bark extracts have antioxidant properties. This work examined bench scale extraction on the yield, the composition and antioxidant properties of Pinus radiata. Acetone solvent (98.7% w/w at 120 °C) yielded maximum phenols concentration, tannins concentration, anti-radical activity (DPPH) and reducing activity (FRAP), although its extraction yield was the lowest. When the organic solve...

Objective: Insomnia is accompanied by several health complications and the currently used soporific drugs can induce several side effects such as psychomotor impairment, amnesia, and tolerance. The present study was planned to investigate the sleep prolonging effect of Pinus eldarica. Materials and Methods: Hydroalcoholic extract (HAE) of P. eldarica, its water fraction (WF), ethyl acetate frac...

Microorganisms play a crucial role in litter decomposition terrestrial ecosystems. The leaf and fine root litters of Robinia pseudoacacia Linn., Quercus acutissima Carr., Pinus tabulaeformis Carr. densiflora Sieb. were analysed using the nylon bag method Illumina MiSeq high-throughput sequencing for amplification bacterial 16S rRNA V4–V5. We assessed effects species on community after one year’...

In this study, the fermentation characteristics of pine needles were investigated for first time and possibility using them as plant-derived feed additives was confirmed. Four types fermented needle prepared: (1) natural (CON); (2) Lactobacillus plantarum SK4315 (LPF); (3) Saccharomyces cerevisiae SK3587 (SCF); (4) co-culture (CCF). Fermentation lasted 48 h, samples taken at 4-h intervals until...

Arbuscular mycorrhizal and ectomycorrhizal symbioses are among the most important drivers of terrestrial ecosystem dynamics. Historically, the two types of symbioses have been investigated separately because arbuscular mycorrhizal and ectomycorrhizal plant species are considered to host discrete sets of fungal symbionts (i.e., arbuscular mycorrhizal and ectomycorrhizal fungi, respectively). Non...

The chemical constituents and biological activity of Pinus cembra L. (Pinaceae), native to the Central European Alps and the Carpathian Mountains, are not well known. The aim of the present work was to examine the phenolic content, antioxidant and antimicrobial effects of hydromethanolic extracts of Pinus cembra L. bark and needles. Bark extract had higher concentrations of total phenolics (299...

The study of population genetic structure and historical dynamics species with disjunct distribution can reveal the mechanisms through they were formed. Pinus densiflora is an essential tree ecological economic value, its natural shows a pattern. Using transcriptome-level SNP data from 220 samples representing 32 naturally-distributed populations in East Asia, we investigated diversity structur...

To obtain basic data for further use of bamboo culms and wood as eco-friendly bioenergy resources, the proximate analysis Dendrocalamus giganteus, D. asper, Bambusa vulgaris, Gigantochloa apus, Phyllostachys pubescens, Pinus densiflora, Quercus variabilis carbonized at 200 to 320 °C 40 intervals was undertaken. Proximate moisture content, ash volatile matter, fixed carbon content performed acco...
