Chemical and Physical Methods to Analyze a Multicomponent Traditional Chinese Herbal Prescription Using LC-MS/MS, Electron Microscope, and Congo Red Staining

Abstract: This study develops several chemical and physical methods to evaluate the quality of a traditional Chinese formulation, Jia-Wei-Xiao-Yao-San. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) coupled with electrospray ionization was used to measure the herbal biomarkers of saikosaponin A, saikosaponin D, ferulic acid, and paeoniflorin from this herbal formula. A scanning electron microscope (SEM) and light microscopy photographs with Congo red staining were used to identify the cellulose fibers if raw … Show more

“…The study of bioactive constituents extracted by JWXYS is not clarified thoroughly. A previous study reveals that saikosaponin A and saikosaponin D in Radix Bupleuri (Chai-Hu), ferulic acid in Radix Angelicae Sinensis (Dang-Gui), and paeoniflorin in Radix Paeoniae Alba (Bai-Shao) and Cortex Moutan Radicis (Mu-Dan-Pi) would be extracted in JWXYS [ 39 ]. Furthermore, flavonoids in several herbs and glycyrrhizic acid in Radix Glycyrrhizae Uralensis (Zhi-Gan-Cao) are water-soluble components in JWXYS and could be extracted by water.…”

“…In contrast, modern Chinese medicinal preparations generally use ethanol as a solvent in the extraction process. The chemical compositions of water decoction and ethanol extraction are different Lu et al, 2013;Wang et al, 2013). Compared with the former, ethanol can extract a lot of lipidsoluble constituents such as fatty acid components.…”

“…Congo red has recently been used to identify cellulose fibril content in phytochemistry [ 34 ]. Through noncovalent affinity and synthesizing a red complex, Congo red has a strong interaction with polysaccharides [ 31 ]. An Aperio ScanScope slide scanner was used to confirm and identify cellulose fibers through Congo red staining.…”

“…A series of physical examinations were performed to assess the starch and raw herbal content in the pharmaceutical herbal products. Based on previous analysis [ 9 , 31 , 35 ], data analysis can be a rapid and reliable indicator of quality control, and it can be used to determine whether raw herbal powders and starch were added to XSLJZT. The photograph of KI-stained cornstarch was used as a positive control to confirm the normal condition of cornstarch for this study.…”
