Abstract

The result  of  chemical analyses of 6 wood species from  West Java is presented  in this report.  The analyses comprised of determination of  cellulose,   lignin,  pentosan   and  extractive  contents.The result shows  that  specific  gravity  ranges from  0.40  to 0.47,  cellulose  content   from  45.4  to  60.6 percent, lignin from  22.5 to 33,2  percent,  pentosan  from  15,1 to 18, 7 percent  and extractive from  0.8 to 2.7 percent.

Abstract

The result of oleoresin from Cassia vera bark by percolation process is presented in this report. The analyses comprise of the determination of oleoresin yield, essential oil and cinnamic aldehyde. The determination based on oven dry weight revealed that oleoresin yield vary from  6.27- 7.48 percent; essential oil content from 8.10-9.92 percent and cinnamic aldehyde content from 39.53-41.59 percent. The optimum yield of oleoresin was produced at temperature of 25°C and with two hours time of percolation process. Temperature and time of percolation process indicated a non significant effect to the cinnamic aldehyde yield.
