Wood/Bark Extracts as Adhesives and Preservatives

The current pot trial was conducted to estimate the impacts of different types of biochar on the growth and nutrients availability of maize (Zea mays) and their effects on the properties of soil. Treatments including four different feedstock based biochar i.e wheat straw, rice husk, corn cob and wood bark were applied to the soil in 10 kg pots @ 1.5% w/w. The experiment was carried out using complete randomized design (CRD). The crop was harvested after the plants have completed their vegetative growth. Physiological parameters of the crop (plant height, leaf area, chlorophyll content) were measured before harvesting while shoot mass (fresh and dry) and root mass (fresh and dry) were calculated after harvesting of the crop. The data showed a significant difference when compared with the control. Plant height was significantly increased from 140cm (control) to 159.9cm in T4 (wood bark biochar). Experimental soil was analyzed in the laboratory for NPK, water aggregate stability, organic matter and active carbon. Wet aggregate stability value of the soil was improved from 17.82% to 19.5%. Similarly soil active carbon was significantly improved from 259.33 ppm to 321.25 ppm. The data showed more significant results of wood bark biochar. Nutrient availability in the soil and plant nutrients uptake N (21.6%), P (31.25%) and K (45%) was increased as a results of biochar incorporation in the soil.

Erythro-carolignan E (1) has been obtained from the ethanol extract of the wood bark of Durio affinis Becc. This research was conducted in order to prove that conformational preferences of compound 1 were solvent dependent. On the basis of 1H-NMR data, the relative configuration of compound 1 was characterized by a coupling constant (3JHH) value of 3.3 Hz at H-7' in CDCl3. The coupling constant (3JHH) values of H-7' in compound 1 has changed to 4.1 Hz and 5.3 Hz in pyridine-d5 and acetonitrile-d3 respectively. As a result, the conformation of compound 1 at C7'-C8' has changed in different NMR solvents. In conclusion, structure oferythro-carolignan E that contains a dihydroxy group at C7'-C8' is able to change in different NMR solvent.

ABSTRACT Power plants have been using forestry biomasses to produce thermal and electrical energies. However, these industries lack of reliable parameters about their raw material in order to consolidate their position in this market. The present study aimed to characterize forestry wastes from pine (Pinus elliottii) plantations leftover of wood logs processing units. Wood, bark and a mixture of both of them were characterized by prompt (total moisture, hygroscopic moisture, ashes, volatile matter and fixed carbon contents), elementary (S, C, H, N and [O + Halogens] contents), and via wet (holocellulose, lignin and extractives contents) chemical analyses. Indeed, basic density and fuel properties (gross and net calorific values) were also determined. Compared to the wood, the bark presented higher extractives content, which affected the ashes content. Regarding the energetic properties, the bark showed the highest properties, but a detrimental character from an environmental standpoint. The wood-bark mixture presented intermediate properties between these two forestry wastes, but with more approximation to the wood.

A rapid, two-solvent, HPLC-APCI-MS method was developed to identify and quantify four pentacyclic triterpenes (betulinic acid, ursolic acid, α-amyrin and β-amyrin) in extracts of the neotropical medicinal plant Souroubea sympetala. Analysis of plant organs, wood, bark, leaves, immature fruit and flowers, indicated that the phytochemical distribution and quantity of triterpenes varies across the plant, with betulinic acid and ursolic acid the major constituents in the bark, wood, fruit and flowers and the amyrins the major constituents of the leaves.
