Traditional cellulose wrapping paper existing many problems, such as poor barrier, easy water absorption, etc. Herein, cellulose, polylactic acid non-woven fabric and antibacterial short fiber as raw materials, via wet papermaking process, prepared a biodegradable and antibacterial composite paper...

Clarisia racemosa (guariúba), Moraceae, is a native tree of the Amazon region, with timber value in the local market and for export. Aiming to contribute to the biological study of the crude extract, we carried out its hydroalcoholic extraction and physicochemical characterization. The results...

The antimicrobial characteristics of Australian commercial timber species were studied using a direct screening method and two different microorganisms. The effectiveness of timber samples was compared with plastic and paper samples during an incubation period of 24 h at 37°C. The initial data with ...

A new sesquiterpene glycoside, ceibanoside (1), was isolated from the leaves of Bombax ceiba, together with the previously-reported quercetin (2), kaempferol (3), naringenin (4), (+)-epicatechin (5), and procyanidin B2 (6). The structure of the new sesquiterpene glycoside was elucidated using...

One new limonoid, named siamensinolide (1), together with two known limonoids (2 and 3) and eight carbazole alkaloids (4-11) were isolated from the twigs of Chalcas siamensis Tanaka. Their structures were elucidated by spectroscopic methods, mainly 1D and 2D NMR spectroscopy. O-methylclausenolide...

Twelve undescribed abietane-type diterpenoids, along with ten known analogues were isolated from the twigs and leaves of Torreya grandis var. merrillii Hu. Their structures were characterized by spectroscopic data analyses, single-crystal X-ray diffraction, and ECD spectra. Torgranols A-C possess...

At present, the reuse of corn stalk (CS) or other biomass stalk generally requires crushing or dissolution, which leads to waste of energy and use of toxic chemicals. In this work, porous CS was directly utilized without any pretreatment as furniture and building materials by loading silver...

Silver nanoparticles (AgNPs) exhibit broad spectrum antibacterial effect, but their cores after use can persist in the environment, which presents a toxic effect on humans. To address this issue, silver-based biomaterials are regarded as green alternatives to AgNPs. In this study, we used kraft...

This study was conducted to investigate the potential of the neutral extract (NE) prepared by treating P. radiata bark with a queous NaHCO₃ solution as a natural dyestuff. Silk and cotton fabrics were dyed at four different NE concentrations, 0.5%, 1.0%, 1.5%, and 2.0% o.w.b. (on the weight of...

Bacteria are becoming resistant to new generation antibiotics day by day, which in turn lead us to find new antibacterial compounds of plant origin. Objective of this study was to assess in-vitro antibacterial activities of methanol extractives of fruits of four plants namely Kleinhovia hospita,...
