ObjectiveTo reveal the influence of Jianchangbang characteristic processing method on the change process of volatile components and the processing mechanism of reducing toxicity and increasing efficiency of Magnoliae Officinalis Cortex（MOC） by studying the changes in the composition and content of volatile components during the processing of ginger processed Xingpo pieces. MethodSamples of raw products， ginger juice moisturized products and stir-fried and heap moisturized products of MOC were taken according to the set time points， and headspace gas chromatography-mass spectrometry（HS-GC-MS） was used to determine the contents of volatile components in the samples， and the relative content of each component was obtained by peak area normalization. Principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were performed on the sample data using SIMCA 14.1 software， and the differential components during the processing were screened with variable importance in the projection（VIP） value>1 as the indicator. ResultA total of 68 volatile components were identified in the samples， among which some of the chemical components with similar structures showed similar trends of changes， and there was also the phenomenon of interconversion between compounds. Compared with the raw products， the contents of 42 components in ginger juice moisturized products increased， while the contents of 25 components decreased， 19 components were unique， and 4 components were unique to the raw products. Compared with ginger juice moisturized products， MOC in the early stage of piling had three unique components， and the contents of 11 components such as cyclosativene and （+）-α-pinene increased， and the contents of 5 components such as tricyclic terpene and α-curcumene decreased， and ginger juice moisturized products had four unique components. Compared with the early stage of piling， in the later stage， the contents of 8 components such as （+）-α-pinene and camphene significantly increased， while the contents of 6 components such as linalool and α-selinene significantly decreased. During the processing of MOC， there were significant changes in the chemical composition of the samples before and after 20 days. The differences between ginger juice moistening and the early stage of piling， the early stage and the later stage of piling could be clearly distinguished. ConclusionDuring the preparation process of ginger processed Xingpo pieces， the addition of ginger juice can reduce the contents of stimulating components， and the contents of active components continue to increase in several stages， such as the addition of ginger juice， frying and heap moisturizing， the quality of the decoction pieces may change significantly at about 20 d of processing. This study can provide a research basis for exploring the processing mechanism of ginger processed Xingpo pieces.

Background: Currently, traditional methods of treating acute gastric ulcer (AGU) have many drawbacks, necessitating an alternative therapy with fewer adverse effects. Atractylodis Macrocephalae Rhizoma (BZ) is known for strengthening the spleen and harmonizing the stomach. BZ processed with Aurantii Fructus Immaturus juice (ZSZBZ), a classic decoction since the Han Dynasty, can enhance the efficacy of BZ. However, the key active components and targets of action of ZSZBZ remain undiscovered. Aim of the study: This study aimed to investigate the bioactive chemical constituents of ZSZBZ against AGU and their possible mechanisms of action, elucidating the scientific content of ZSZBZ processing. Materials and methods: Initially, we examined rat stomach histopathology and conducted ELISA for oxidative stress and inflammation. Subsequently, we investigated underlyingmechanisms using metabolomics. Further analysis of potent components and key targets in ZSZBZ was conducted through liquid chromatography-mass spectrometry analysis combined with network pharmacology. Finally, key targets were analyzed by Western blot. Results: ZSZBZ improved gastric histopathology, reversing high alcohol-induced oxidative stress (SOD, CAT) and inflammatory level (TNF-α, IL-6) disorders. This is associated with ZSZBZ’s regulation of amino acid metabolism, energy metabolism, and inflammatory response-related metabolic pathways, along with key targets PTGS2, MAPK1, and KDR. The significant increase in potency of ZSZBZ may be attributed to elevated levels of naringenin, hesperidin, hesperidin, and rhamnoceroside after concoction. Conclusions: Combining metabolomics and network pharmacology, this study elucidated that ZSZBZ enhanced gastroprotection by modulating amino acid metabolism, antioxidant, and inflammation-related targets and pathways, providing insights into the bioactive compounds and potential mechanisms of herbal concoctions.
