DEVELOPMENT OF A GAS CHROMATOGRAPHY METHOD FOR QUANTIFICATION OF TRITERPENES IN THE COMMERCIAL OLEORESINS FROM PROTIUM SPECIES

Development of a gas chromatography method for quantification of triterpenes in the commercial oleoresins from Protium species

Abstract Crude non-volatile oleoresin from Burseraceae species (breu), a non-timber forest product of the Amazon, still lacks methods for its quality control even though its pharmacological activities have been associated to the major triterpenes α-amyrin (αAA), β-amyrin, α-amyrenone, β-amyrenone and lupeol (LU).Its chemical characterization h

Effects of Lime and Compost on Chemical Characteristics and Soil Hydraulic Conductivity of Alfisols at ATP Jatikerto Coffee Plantation

Coffee in Indonesia is currently one of the most important plantation commodities.Inappropriate management of coffee plantations causes low soil quality especially in smallholder coffee plantations, one of which is the density (compaction) of soil in coffee plantations that has a clayey texture.This study was aimed to analyze the Electrical effect
