Postharvest fruit losses are largely driven by a short shelf-life resulting from ethylene-induced ripening, microbial spoilage, and moisture loss. In this study, a multifunctional coating was fabricated on Moso bamboo substrates via a simple two-step process. The coating integrates superhydrophobic, ethylene-scavenging, and antibacterial functions, utilizing rosin, nano-ZnO, Artemisia argyi powder, nano-CaCO3, and KMnO4. The bamboo with this coating acts as an indirect preservation platform, regulating the storage microenvironment to reduce ethylene accumulation, microbial proliferation, and water loss. The system is cost-effective, biosafe, and scalable for practical use. Shelf-life tests demonstrated significant extension for both climacteric and nonclimacteric fruits: bananas (from 5 to 21 days, ≥200%), strawberries (1–2 to 5 days, ≥150%), blueberries (5–7 to 15 days, ≥114%), cherry tomatoes (4–7 to 14 days, ≥100%), and sweet cherries (5–7 to 14 days, ≥100%). The synergistic effect of ethylene adsorption, moisture barrier, and contact-plus vapor-phase antibacterial action contributes to the broad-spectrum efficacy of this approach. These findings support this coating as a promising passive packaging material for fresh produce preservation.

Artemisiae Argyi Folium (AAF) is a medicinal and edible herb whose quality is dependent on its geographical origin and aging years. This study employed untargeted metabolomics based on GC–MS and UHPLC-HRMS to identify its geographical origin and aging years. First, we employed our proprietary AntDAS platform to fully analyze the mass spectrometry data and screen for key differential metabolites. Analysis identified 58 geographical origin-related metabolites (35 non-volatile and 23 volatile). Notably, the chemical profiles of the two Dao-di production regions differed markedly. Samples from Nanyang (Henan) were characterized by high abundances of endo -borneol, terpinen-4-ol, eucalyptol, 3,4-dicaffeoylquinic acid, phellopterin, and quercetin, whereas these compounds were found in low abundance in samples from the other Dao-di production region, Qichun (Hubei). Furthermore, 27 metabolites with aging-year differences were identified, comprising 18 non-volatile and 9 volatile compounds, and the aged AAF compared to fresh AAF showed significantly enriched chemical components. Regarding the aging effect, the contents of eucalyptol and 5-methyl-decane were highest in the 5-year samples. Endo -borneol showed higher levels in both 1-year and 5-year samples, with its content in 3-year samples being intermediate. In contrast, n-hexadecanoic acid and phytol were more abundant in samples aged for over 5 years. Finally, using these differential metabolites, OPLS-DA models achieved 100.0% accuracy in geographical origin classification and over 94.4% accuracy for aging year discrimination. This study provides a chemical basis for the geographical origin traceability and aging year identification of food-drug homologous products.

To reveal the utilization value of leaf, stem, and root of Artemisia argyi , a rapid online liquid microextraction combined with a high-performance liquid chromatography coupled with 2,2-nitrogen-di (3-ethyl-benzothiazole-6-sulfonic acid) diammonium salt antioxidant assay system was established for analysis of antioxidants in the leaf, stem, and root of A. argyi , and a calibration quantitative method of antioxidant activity with equivalent chlorogenic acid was proposed. Thirty-three positive peaks were identified; among them, 12 compounds were found that possess good antioxidant activity including eleven organic acids (components 2–4, 8, 11–14, 17, 19, and 21) and one flavonoids (component 22). The proposed calibration quantitative method avoided the influence of content of compound and compared the extent of radical scavenging capacity of five antioxidant compounds, which were ranked as follow: 3,5-dicaffeoylquinic acid > 3,4-dicaffeoylquinic acid ≈ 4,5-dicaffeoylquinic acid > 1,4-dicaffeoylquinic acid > chlorogenic acid. In conclusion, this study provided composition and biological potential for the future development of the leaf, stem, and root of A. argyi . It is believed that the online liquid microextraction combined with high-performance liquid chromatography based antioxidant assay system can be widely used for the rapid screening of natural antioxidant components in the different parts of natural products.
