miroestrol, deoxymiroestrol, and kwakhurin (KWA). In this study, we described the facile synthesis of KWA, a marker compound of P. mirifica. Our revised synthetic method produced KWA with shorter steps and higher yield than the reported method. Furthermore, the absolute purity of KWA was determined by quantitative NMR analysis for standardization as a reagent, and its purity was 92.62 ± 0.12%. Graphical Abstract

奥克尔膳食补充剂(得自葛根的块根)的副作用。为了控制夸克keur产品的质量,需要通过特征性的标记化合物(如miroestrol,deoxymiroestrol和kwakhurin(KWA))来保持其成分。在这项研究中,我们描述了易于合成的P. mirifica标记化合物KWA 。我们改良的合成方法生产的KWA比报道的方法步骤更短,产率更高。此外,通过定量NMR分析确定了KWA的绝对纯度,以用于作为试剂的标准化,其纯度为92.62±0.12%。 图形抽象全尺寸图像
