Two identification tests, sublimation and color reaction, described in the 10th revision of Japanese Pharmacopoeia and analysis by gas chromatography were carried out to evaluate 14 samples of commercial benzoin in comparison with raw materials for making blended (compressed) benzoin at Shingapore and standard resin obtained from Styrax paralleloneurum PERKINS in Indonisia. High graded resin from S. paralleloneurum was called 'haminjon toba' and contained about 3,0.5 and 20-30% of benzoic acid, vanillin and cinnamic acid, respectively. Low graded one and resin from S. benzoin DRYANDER, which was called 'jurur', contained about 30% of benzoic acid but no cinnamic acid. Only three samples were suitable for both description and identification tests, and another two samples which were identified to be the best and second class of resin from S. paralleloneurum were agreeable with the tests only, and the remainder almost fitted the description but the tests were negative. Color reaction was discussed. New pure benzoin showed deep red-purple and old one showed the same deep red-purple to deep red-brown. A kind of damar, 'damar batu', had deep red-brown, but a raw material of low graded had light brown in color reaction, though its sublimation test was positive.
