从葡萄牙松香树脂中分离出15-羟过氧基松酸(15-HPA)并鉴定为其甲酯。利用紫外线、红外线、核磁共振和质谱技术阐明了该化合物的结构。在经过松香敏感豚鼠的测试中,发现15-HPA甲酯是一种诱导物。在同一物种中验证了其致敏能力,并认为15-HPA甲酯是一种强烈的过敏原。在已知对松香过敏的患者中也验证了其诱发潜力。研究的葡萄牙松香树脂中含有约1%的15-HPA。基于其致敏性和分离量,我们得出结论:15-HPA是葡萄牙松香树脂中的主要接触过敏原。
15-Hydroperoxyabietic acid (15-HPA) has been isolated from Portuguese colophony of the gum rosin type and identified as its methyl ester. The structure of the compound was elucidated using UV, IR, NMR and mass spectrometry. 15-HPA methyl ester was found to be an elicitor when tested in colophony-sensitized guinea-pigs. The sensitizing capacity was verified in the same species and 15-HPA methyl ester was considered to be a strong allergen. The eliciting potential was also verified in patients with known allergy to colophony. The Portuguese gum rosin investigated contained approximately 1% of 15-HPA. Based on its allergenicity and the amounts isolated, we conclude that 15-HPA is a main contact allergen in Portuguese gum rosin.
