A simple, rapid, accurate and selective 1H NMR spectroscopic method to detect and quantify euglobals in the leaves of Eucalyptus loxophleba ssp. lissophloia has been developed. The method allows for the estimation of total concentration of diformylphloroglucinol-monoterpene adducts, as well as the quantitation of sabinene- and alpha/beta-phellandrene-adducts, separately. The method was validated for accuracy, precision and linearity using as reference standards 2-ethyl phenol and mixtures of jensenone, a monomeric formylated phloroglucinol, and 2-ethyl phenol.
已开发出一种简单、快速、准确且具选择性的¹H核磁共振光谱法，用于检测和定量测定阔叶桉叶中的优球蛋白。该方法能够分别估算二甲酰基间苯三酚-单萜加合物的总浓度，以及桧烯和α/β-水芹烯加合物的含量。使用2-乙基苯酚以及作为参考标准的詹森酮（一种单体甲酰化间苯三酚）与2-乙基苯酚的混合物，对该方法的准确性、精密度和线性进行了验证。
