The transfer of this plasmid via the conjugative pilli of Escherichia coli was reduced by 76.5 ± 2.0% and 79.0 ± 1.2% by hexane extract and methanol fraction of M. lowiana, respectively. The hexane extract exhibited significant anti-conjugant activity at a non-cytotoxic concentration of 100 mg/L as assessed against adult human dermal fibroblast cells. The hexane extract and methanol fraction were screened using phytochemical tests, NMR spectroscopy, IR spectroscopy, and high-resolution electrospray ionization mass spectrometry (HRESIMS) and were found to contain terpenoids, sterols, and fatty acids. date: 2020 date_type: published official_url: http://dx.doi.org/10.1155/2020/1604638 oa_status: green full_text_type: pub pmcid: PMC7321511 language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1798186 doi: 10.1155/2020/1604638 lyricists_name: Stapleton, Paul lyricists_id: PDSTA67 actors_name: Stapleton, Paul actors_name: Harris, Jean actors_id: PDSTA67 actors_id: JAHAR68 actors_role: owner actors_role: impersonator full_text_status: public publication: Evidence-Based Complementary and Alternative Medicine volume: 2020 article_number: 1604638 event_location: United States issn: 1741-427X citation: Kwapong, AA; Soares, S; Teo, SP; Stapleton, P; Gibbons, S; (2020) Myristica lowiana Phytochemicals as Inhibitor of Plasmid Conjugation in Escherichia coli.
