The chemical composition of sandarac resin was investigated qualitatively and quantitatively by gas chromatography-mass spectrometry (GC-MS). Six compounds with labdane and pimarane skeletons were identified in the resin. The obtained mass spectra were interpreted and the mass spectrometric behaviour of these diterpenoids under EI conditions was described. Quantitative analysis by the method of internal standard revealed that identified diterpenoids represent only 10-30% of the analysed sample. The sandarac resin from different suppliers was analysed (from Kremer, Okhra, Color Rare, La Marchande de Couleurs, L'Atelier Montessori, Hevea). The analysis of different lumps of resins showed that the chemical composition differs from one lump to another, varying mainly in the relative distributions of the components.
采用气相色谱-质谱联用仪（GC-MS）对山达脂树脂的化学成分进行了定性和定量研究。在该树脂中鉴定出了六种具有半日花烷和海松烷骨架的化合物。对所得质谱进行了解释，并描述了这些二萜类化合物在电子轰击（EI）条件下的质谱行为。采用内标法进行定量分析表明，所鉴定的二萜类化合物仅占分析样品的10%-30%。对来自不同供应商（克雷默、奥赫拉、珍稀色彩、色彩商人、蒙台梭利工作室、三叶橡胶公司）的山达脂树脂进行了分析。对不同树脂块的分析表明，其化学成分因树脂块不同而有所差异，主要体现在各成分的相对分布上。
