A study on chemical analysis and water repellency property of ten village wood species was conducted to find out the percentages of their chemical components. It was found that raintree (Samanea saman) possessed the highest amount of water soluble extractives. It was followed by Babla (Acacia nilotica sub. indica), mango (Mangifera indica) and Painya mandar (Erythrina ovalifolia). Neem (Azadiachta indica) and jackfruit (Artocarpus heterophyllus) contained the least amount of this kind of extractives. Alcohol-benzene soluble extractives of the species fell in the range of 1.38-6.60%. The holocellulose content was the highest in Tentul (Tamarindus indica). Ghora neem (Melia azadarach) ranked the next in this respect. In consideration to the cellulose content, Tentul, Ghora neem, sissoo (Dalbegraia sissoo), mango and Babla may be suitable for chemical pulping and conversion products. These ten species were explored for water repellency test. Neem was found to absorb the least amount of water. In order of gradation on this aspect sissoo, Babla and Tentul were found to absorb slightly more water. These species may be suitable both for indoor and outdoor uses. Sorption of water in the remaining six species is considerably higher and consequently they are deemed not suitable for outdoor uses.
