 ABSTRACT

Pinus roxburghii is an important commercial species of the Himalayan region, it is also known for its timber, paper pulp and resin yield. The present study on chemical composition of Pinus roxburghii wood from 10 different locations of Himachal Pradesh was carried out. Five wood samples from different trees were taken from each site. These were further analysed for moisture content and chemical composition. The results revealed thatmaximum moisture content (18.32 %) and cold water soluble extractives (7.52 %) were found in Ghanahatti population. Maximum hot water soluble extractives (9.47 %) and Klason-lignin content (33.58 %) were observed in the wood samples from Nihari. Whereas, alcohol-benzene and holocellulose contents of 14.15 and 70.44 per cent were recorded in Ghanahatti and Sarahan locations, respectively.

Key words: Pinus roxburghii, Hot water soluble extractive, Klason-lignin content, Alcohol-benzene, Holocellulose.
