Cyclic polyalcohol composition of 80 natural wood samples from different botanical species, with the majority of them used in the oenology industry for aging purposes, has been studied by gas chromatography-mass spectrometry (GC-MS) after its conversion into their trimethylsilyloxime derivatives. Each botanical species showed a different and specific cyclic polyalcohol profile. Oak wood samples were characterized by the richness in deoxyinositols, especially proto-quercitol. Meanwhile, other botanical species showed a very low content of cyclic polyalcohols. The qualitative and quantitative study of cyclic polyalcohols was a useful tool to characterize and differentiate woods of different botanical origin to guarantee the authenticity of chips used in the wine-aging process. Monosaccharide composition was also analyzed, showing some quantitative differences among species, but cyclic polyalcohols were the compounds that revealed the main differentiation power.
已通过气相色谱-质谱联用（GC-MS）对来自 80 种不同植物物种的 80 种天然木材样本中的环状多元醇进行了研究，这些样本大多数用于葡萄酒行业的陈酿目的。在将其转化为三甲基硅烷肟衍生物后进行了研究。每个植物物种都表现出不同且特定的环状多元醇特征。橡木样本的特点是富含去氧肌醇，特别是原奎糖醇。同时，其他植物物种的环状多元醇含量非常低。环状多元醇的定性和定量研究是一种有用的工具，可以对不同植物来源的木材进行特征描述和区分，以保证用于葡萄酒陈酿过程的木屑的真实性。还分析了单糖组成，发现不同物种之间存在一些定量差异，但环状多元醇是显示主要区分能力的化合物。
