Dingkun Dan (DKD), a famous traditional Chinese medicine, has been widely used in the treatment of irregular menstruation, leucorrhea abnormality, and postpartum gynecological diseases since Qing dynasty (1739). It comprises 30 flavors of Chinese medicinal materials, which results in its complex chemical composition. In this study, an integrative method was developed to rapidly characterize the chemical components of DKD using ultra‐high‐performance liquid chromatography quadrupole time‐of‐flight mass spectrometry combined with the UNIFI™ software. A total of 234 compounds, including 47 triterpenoid saponins, 55 flavonoids, and 38 alkaloids, were identified. Of them, 170 compounds were characterized initially and 61 compounds were identified unambiguously using reference standards. Under the same analysis conditions, 43 prototypical components, which were tentatively assigned as triterpenoid saponins, flavonoids, alkaloids, terpenoids, phenylpropanoids, and others, were absorbed in rat by serum pharmacochemistry analysis. DKD exhibited diverse pharmacological activities through the combined effect of these components. This study was the first systematic study of chemical components in vitro originating from 30 medicinal materials and prototypes in vivo of DKD, which could provide scientific evidence for explaining its therapeutic effect.

使用超高效液相色谱四极杆飞行时间质谱仪结合UNIFI™软件，对定坤丹的化学成分进行体外和体内原型的系统表征。

自清朝（1739年）以来，著名的中药丁坤丹（DKD）已被广泛用于治疗月经不调，白带异常和产后妇科疾病。它包含30种口味的中药材，导致其化学成分复杂。在这项研究中，开发了一种集成方法，以结合使用UNIFI™软件的超高效液相色谱四极杆飞行时间质谱快速表征DKD的化学成分。共鉴定出234种化合物，包括47种三萜皂苷，55种黄酮和38种生物碱。其中，最初鉴定了170种化合物，使用参考标准明确鉴定了61种化合物。在相同的分析条件下，有43个原型组件，暂定为三萜皂苷，类黄酮，生物碱，萜类，苯丙烷等的化合物通过血清药理分析在大鼠中吸收。DKD通过这些成分的组合作用表现出多种药理活性。这项研究是对DKD体内30种药用材料和原型产生的体外化学成分的首次系统研究，可为解释其治疗效果提供科学依据。
