Pyrolysis gas chromatography at 450° was investigated for the identification of natural resins. Each natural resin tested gave different pyrogram, and the characteristic peaks were identified as follows : From Copal, m- and p-xylene, and limonene, acetone from Rosins, C₉H₁₄ and isoprene from Gamboge, ethyl acetate from Guaiacum, methanol from Dragon's Blood, toluene and styrene from Storax and Peru Balsam, and monoterpene compounds from Elemi and Canada Balsam. Consequently, it was concluded that natural resins can be identified by their characteristic pyrogram at 450°.
