Pharmacophagous plants are rich in bioactive compounds that constitute a safe drug library for antimicrobial agents. In this study, we have deciphered for the first time antibacterial ingredients and modes of the methanol-phase extract (MPE) from the fruit of Amomum villosum Lour. The results have revealed that the antibacterial rate of the MPE was 63.64%, targeting 22 species of common pathogenic bacteria. The MPE was further purified by high performance liquid chromatography (Prep-HPLC), and three different constituents (Fractions 1\u20133) were obtained. Of these, the Fraction 2 treatment significantly increased the cell membrane fluidity and permeability, reduced the cell surface hydrophobicity, and damaged the integrity of the cell structure, leading to the leakage of cellular macromolecules of Gram-positive and Gram-negative pathogens (p &lt; 0.05). Eighty-nine compounds in Fraction 2 were identified by ultra HPLC-mass spectrometry (UHPLC-MS) analysis, among which 4-hydroxyphenylacetylglutamic acid accounted for the highest 30.89%, followed by lubiprostone (11.86%), miltirone (10.68%), and oleic acid (10.58%). Comparative transcriptomics analysis revealed significantly altered metabolic pathways in the representative pathogens treated by Fraction 2 (p &lt; 0.05), indicating multiple antibacterial modes. Overall, this study first demonstrates the antibacterial activity of the MPE from the fruit of A. villosum Lour., and should be useful for its application in the medicinal and food preservative industries against common pathogens.<\/jats:p>","DOI":"10.3390\/plants13060834","type":"journal-article","created":{"date-parts":[[2024,3,14]],"date-time":"2024-03-14T05:43:30Z","timestamp":1710395010000},"page":"834","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Antibacterial Ingredients and Modes of the Methanol-Phase Extract from the Fruit of Amomum villosum Lour."],"prefix":"10.3390","volume":"13","author":[{"given":"Kaiyue","family":"Zhang","sequence":"first","affiliation":[{"name":"Key Laboratory of Quality and Safety Risk Assessment for Aquatic Products on Storage and Preservation, Ministry of Agriculture and Rural Affairs of the People\u2019s Republic of China, Shanghai 201306, China"},{"name":"College of Food Science and Technology, Shanghai Ocean University, Shanghai 201306, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fengfeng","family":"Cao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Quality and Safety Risk Assessment for Aquatic Products on Storage and Preservation, Ministry of Agriculture and Rural Affairs of the People\u2019s Republic of China, Shanghai 201306, China"},{"name":"College of Food Science and Technology, Shanghai Ocean University, Shanghai 201306, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yueliang","family":"Zhao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Quality and Safety Risk Assessment for Aquatic Products on Storage and Preservation, Ministry of Agriculture and Rural Affairs of the People\u2019s Republic of China, Shanghai 201306, China"},{"name":"College of Food Science and Technology, Shanghai Ocean University, Shanghai 201306, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2414-0609","authenticated-orcid":false,"given":"Hengbin","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Division of Hematology, Oncology, and Palliative Care, Massey Cancer Center, School of Medicine, Virginia Commonwealth University, Richmond, VA 23298, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lanming","family":"Chen","sequence":"additional","affiliation":[{"name":"Key Laboratory of Quality and Safety Risk Assessment for Aquatic Products on Storage and Preservation, Ministry of Agriculture and Rural Affairs of the People\u2019s Republic of China, Shanghai 201306, China"},{"name":"College of Food Science and Technology, Shanghai Ocean University, Shanghai 201306, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Chow, F.W.
