: Bupleuri radix and liquorice are commonly used as a hepatoprotectants. Their main effective ingredients are triterpenoid saponins. It is known that the saponins in liquorice and Bupleuri radix not only promote the metabolism of sugar and lipids but also have anti-inflammatory functions and hepatoprotective effect. However, the complexity of these compounds results in difficulty in studying their pharmacodynamics and mechanism. In this study, glycosides were the main components that were identified and selected as the main research object. First, the mass spectrometry information of the main chemical components in liquorice and Bupleuri radix were collected from the literature. The characteristic fragments and neutral losses were summarized according to typical cleavage methods. Second, the samples were analysed using ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry, and characteristic fragment filters and neutral loss filters were successfully applied to screen 18 saponins from Bupleuri radix and 23 saponins and nine flavonoid glycosides from liquorice. Rapid classification and identification of the main components in Bupleuri radix and liquorice were finally achieved. This method promoted the development of chemical components in Bupleuri radix and liquorice, and provided a new way for screening, classifying, and identifying target components in complex samples of metabolomics and pharmacokinetics.

Licorice is one of the most generally used herbal medicines in the world; however, wild licorice resources have decreased drastically. Cultivated Glycyrrhiza uralensis Fischer are the main source of licorice at present, but the content of main active components in cultivated G. uralensis are lower than in wild G. uralensis. Therefore, the production of high-quality cultivated G. uralensis is an urgent issue for the research and production fields. In this study, the content of five active compone...

Abstract 18β-Glycyrrhetinic acid (18Gly), the major bioactive component of Glycyrrhizae Radix, possesses anti-ulcerative, anti-inflammatory, and other pharmacological properties. Although 18Gly is associated with immunoregulatory functions of allergic diseases, the pathophysiological mechanisms of 18Gly action in allergic inflammatory lung disease have not been examined. Moreover, there are no in vivo studies on the anti-asthmatic effects of 18Gly in allergic asthma. We investigated its effect a...

Human carboxylesterase 2 (hCES2A) is a key target to ameliorate the intestinal toxicity triggered by irinotecan that causes severe diarrhea in 50%–80% of patients receiving this anticancer agent. Herbal medicines are frequently used for the prevention and treatment of the intestinal toxicity of irinotecan, but it is very hard to find strong hCES2A inhibitors from herbal medicines in an efficient way. Herein, an integrated strategy via combination of chemical profiling, docking-based virtual scre...

Abstract Natural products are great treasure troves for the discovery of bioactive components. Current bioassay guided fractionation for identification of bioactive components is time- and workload-consuming. In this study, we proposed a robust and convenient strategy for deciphering the bioactive profile of natural products by mass spectral molecular networking combined with rapid bioassay. As a proof-of-concept, the strategy was applied to identify angiotensin converting enzyme (ACE) inhibitor...
