The effect of puffing treatment on the volatile components of green tea has been studied. A total of 155 volatile compounds were identified by using HS-SPME and SPE extraction methods, combined with gas chromatography–mass spectrometry (GC–MS). The total concentration of volatile compounds in puffed green tea increased by 2.25 times compared to that in before puffing. 12 key volatile compounds in green tea were identified before and after puffing using a combination of multivariate statistical analysis, GC-O, AEDA dilution analysis, and relative odor activity value (rOAV). The puffing process generates the Maillard reaction, where sugars react with amino acids to produce Maillard reaction products (such as pyrazine, pyrrole, furan, and their derivatives), giving them a unique baking aroma. The proportion of these compounds in the total volatile matter increased. The research results provided guidance and a theoretical basis for improving the aroma processing of green tea.

Objective: To explore the therapeutic potential of Cordyceps sinensis (Berk.) Sacc. (C. sinensis, Dong Chong Xia Cao) in an ischemic stroke (IS) model and predict its possible mechanism through network pharmacology. Methods: Thirty-three Sprague–Dawley rats were randomly divided into the Sham, model, and C. sinensis groups. After 5 days of pre-treatment, the model group and the C. sinensis group were subjected to middle cerebral artery occlusion (MCAO) modeling. Effect of C. sinensis on MCAO rats was evaluated by comparing cerebral infarct size, neurological function, cerebral water content, pathological changes, and certain biochemical indicators. Intersection targets between C. sinensis and IS was screened using network pharmacology analysis. Relationship among core components, targets and pathways of C. sinensis in treating IS was constructed through network pharmacology analysis and further verified by molecular docking. Finally, the DAVID v8.8 database was used for performing GO analysis and KEGG pathway enrichment analysis by importing the intersection targets. Results: Compared with the model group, C. sinensis significantly reduced the volume of cerebral infarction (P = .026), the cerebral water content (P = .0013), the mNSS score (P
