Yan Huanglian is the whole grass and rhizome of Corydalis saxicola Bunting (CSB) of the Papaveraceae family. CSB has various pharmacological effects and is a promising ethnopharmaceutical. The chromatographic fingerprint of 16 batches of CSB samples was established in this study. Quantitative analysis of multi-components by single marker and the external standard method (ESM) was used to quantitatively assess seven constituents of CSB. Because of its high stability and availability, dehydrocavidine was used as a reference to determine the relative correction factors (RCFs) of columbamine, epiberberine, coptisine hydrochloride, palmatine chloride, berberine hydrochloride, and chelerythrine based on high-performance liquid chromatography. The calculated quantitative analysis of multi-components by single marker values is consistent with those obtained from the ESM, and the repeatability of the RCFs was demonstrated. For the first time, the quantitative analysis of multi-components by the single marker method has been established for the simultaneous determination of seven components, and it is demonstrated to be feasible and accurate for the quality evaluation of CSB combined with chromatographic fingerprint analysis. The combination of these methods could be used as a reference for quality control in Chinese medicine.

As a traditional Chinese medicine (TCM), Allii Macrostemonis Bulbus (AMB) is a key herb for the treatment of thoracic paralytic cardiac pain, but its quality evaluation method has not yet been fully clarified. In this study, chromatographic fingerprints of AMB were developed using solid-phase extraction–high-performance liquid chromatography–evaporative light scattering detection (SPE-HPLC-ELSD) to evaluate the quality of AMB from various origins and processing methods. This was achieved by employing chemical pattern recognition techniques and verifying the feasibility and applicability of the quality evaluation of AMB through the quantitative analysis of multi-components via a single-marker (QAMS) method. Through the analysis of the fingerprints of 18 batches of AMB, 30 common peaks were screened, and 6 components (adenosine, syringin, macrostemonoside T, macrostemonoside A, macrostemonoside U, and macrostemonoside V) were identified. Moreover, three differential markers (macrostemonoside A, macrostemonoside T, and macrostemonoside U) were screened out using chemometrics techniques, including principal component analysis (PCA), hierarchical cluster analysis (HCA), and orthogonal partial least squares discriminant analysis (OPLS-DA). Subsequently, a QAMS method was established for macrostemonoside T and macrostemonoside U using macrostemonoside A as an internal reference. The results demonstrate the method’s accuracy, reproducibility, and stability, rendering it suitable for the quality evaluation of AMB. This study provides a theoretical basis for drug quality control and the discovery of quality markers for AMB.

In this work, we developed a novel approach to evaluate the contents of bioactive components in rhubarb. The present method was based on the quantitative analysis of multicomponents by a single-marker and response surface methodology approaches. The quantitative analysis of multicomponents by a single-marker method based on high-performance liquid chromatography coupled with photodiode array detection was developed and applied to determine the contents of 12 bioactive components in rhubarb. No significant differences were found in the results from the quantitative analysis of multicomponents by a single-marker and the external standard method. In order to maximize the extraction of 12 bioactive compounds in rhubarb, the ultrasonic-assisted extraction conditions were obtained by the response surface methodology coupled with Box–Behnken design. According to the obtained results, we showed that the optimal conditions would be as follows: proportion of ethanol/water 74.39%, solvent-to-solid ratio 24.07:1 v/w, extraction time 51.13 min, and extraction temperature 63.61°C. The analytical scheme established in this research should be a reliable, convenient, and appropriate method for quantitative determination of bioactive compounds in rhubarb.
