A Practical Protocol for a Comprehensive Evaluation of Sulfur Fumigation of Trichosanthis Radix Based on Both Non-Targeted and Widely Targeted Metabolomics.

ABSTRACT: Trichosanthis Radix (TR) is one of the most severely sulfur-fumigated herbs in the market, whose transformation mechanism of chemical compositions and sulfur-fumigation markers of TR have not been clarified. To excavate characteristic sulfur-fumigation markers of TR samples, this study brings up a practical protocol using both ultra-performance liquid chromatography/quadrupole time-of-flight-mass spectrum (UPLC-ESI-QTOF-MS/MS)-based non-targeted metabolomics and ultra-performance liquid chromatography/electrospray ionization/quadrupole multiple-stage linear ion-trap mass spectrum (UPLC-ESI-QTRAP-MS/MS)-based widely targeted metabolomics. The results of study demonstrated that five characteristic markers are sulfur-containing components, which were identified as p-Hydroxybenzyl hydrogen sulfite, cucurbitacin D sulfite I, cucurbitacin D sulfite II, cucurbitacin B sulfite I, and cucurbitacin B sulfite II, respectively. Additionally, cucurbitacin B and D were also filtered and identified as the characteristic sulfur-fumigation markers. Meanwhile, the different sulfur-fumigation extent of TR samples was tested by chemical transformations analysis and sulfur dioxide residues test. Further, 58.16% (139 of 239) of the differential metabolites content significantly reduced in sulfur-fumigated TR samples. Besides, 20 kinds of non-sulfur marker metabolites were tested to evaluate the quality of TR samples before and after sulfur fumigation, predominantly including phenolic acids, amino acids, lipids and nucleotides. Taking TR as an example, this work provides a comprehensive practical protocol for the quality supervision of sulfur-fumigation herbs.

Project description:With the internationalization of traditional Chinese medicine, the demand for medicinal and edible Codonopsis Radix (CR) is increasing, and its medicinal resources have attracted atten- tion. CR is a famous traditional Chinese medicine with a long pharmaceutical and edible history. Guizhou has abundant CR resources, but in the absence of systematic studies on species identifi- cation and chemical compositions, it has not been fully utilized. The results of plant traits and DNA barcoding molecular identification indicated that Luodang (LD) and Weidang (WD) from Guizhou were Codonopsis tangshen, C. pilosula., respectively. Widely targeted metabolomics analysis revealed that a total of 1116 metabolites from 14 categories, including phenolic acids, lipids, flavonoids, etc., were found in LD, WD, and the three Chinese Pharmacopoeia CR. CRs shared 1054 (94.4%) me- tabolites, with extremely similar metabolite profiles. Affected by Guizhou's particular climate, LD and WD each contained 3 and 10 dominant differential metabolites, respectively, which were pri- marily flavonoids and amino acids. Amino acids, phenolic acids, and organic acids play important roles in the excellent food attributes of them. In CR, 8 dominant differential metabolites were dis- covered for the first time, including isoorientin-7-O-(6′′-feruloyl) glucoside, N-formyl-L-methionine, and cyclo (Phe-Glu), etc. Network pharmacology analyses showed that LD dominant differential metabolites were closely related to anti-tumor, cardiovascular disease improvement, nervous system protection, and metabolic disease treatment, whereas WD was closely related to nervous system protection and cardiovascular disease improvement. In conclu- sion, LD and WD can be used and promoted medicinally as CR and have potential value for new drug development. This work enriched the database of CR compounds and provided a reference for quality control, resource development, and new drug development of CR
