The trunk bark of Tabebuia caraiba Bignoniaceae was found to contain four novel iridoids, 6-O-E-p-coumaroyljioglutin D (2), 6-O-E-p-coumaroyl-3-demethyl-3-O-ethyljioglutin D (3), 6-O-E-p-coumaroyl-1-demethyl-1-O-ethyljioglutin D (4), 7-O-E-p-coumaroyljiofuranaldehyde (5), three known iridoids,...

With the analytical data of 90 trees from 18 sample plots of Populus nigra×P. simonii plantation in Shangzhi Forestry Bureau in 2020, the statistical methods including analysis of covariance, paired t-test, analysis of variance and multiple comparison were used to studythe azimuth variation,...

This article talks about the bark as a secondary raw material formed at the sawmill, plywood and pulp and paper industries, from where the round materials are fed for further processing in debarked form. The article also talks about the uses of the bark as part of the tree, and as a processed...

In recent decades, the development of a modern industrial enterprise is impossible without considering the issue of complex processing or disposal of waste of the main production. This issue is very acute for the enterprises of the wood processing industry. The processing of wood waste should be...

This data was decisive on the adsorption of fluoride by microwave assisted carbonized Azadirachta indica bark (MACAIB) adsorbent material from aqueous solution. Azadirachta indica bark is a plant-based effortlessly available item which is transformed into a carbonaceous adsorbent material and...

This study investigated the swelling behaviours of briquettes made of forest residues (sawdust and bark) and their mixtures with linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE) and polypropylene (PP) under water penetration and 90% relative humidity. The swelling of...

The effects of the radial force applied by a ring tip debarker and the rake angle on debarking quality of frozen and unfrozen black spruce logs were studied. A one-arm ring debarker prototype was built, which controlled the radial force, the rake angle, and the cutting and feed speeds. The...

Background: The antipyretic, analgesic and anti-inflammatory activities of two concentrations (100 and 200 mg/kg) of ethanolic extract of leaf, bark, flower and fruit pulp of C. fistula were determined in male wistar albino rats. Methods: Antipyretic activity was assessed by E. coli endotoxin...

The effect of the radial force applied by a ring debarker tip to frozen black spruce logs, obtained at three positions on the stem, was studied. A one-arm ring-debarker prototype was developed, which controlled the radial force, rake angle, and cutting and feed speeds. The experiment consisted of...

The paper presents the structure of the total above-ground biomass of wild cherry (Prunus avium L.) trees in the area of the Spačva basin in the Vinkovci Forest Administration. The research was performed on 120 samples of wild cherry trees with a diameter at breast height (DBH) ranging from 10 to...
