摘要: This study systematically investigated the liposoluble components and their potential correlation with antibacterial activity in six bast fiber varieties-Apocynum venetum, Corchorus capsularis, Hibiscus cannabinus, Linum usitatissimum, Cannabis sativa, and Boehmeria nivea-using gas chromatography-mass spectrometry (GC-MS). The analysis identified a range of compounds including alkanes, phenols, sterols, esters, and triterpenoids, with notable compositional differences among the fibers. Tetracontane was predominant in A. venetum (40.39%) and H. cannabinus (22.47%), while gamma-sitosterol was highest in C. capsularis (12.80%). L. usitatissimum was rich in n-hexadecanoic acid (9.16%), C. sativa in heptacosanal (8.96%), and B. nivea in both tetracontane (45.42%) and tetracosane (10.09%). Based on existing literature, components such as 2,4-di-tert-butylphenol, gamma-sitosterol, n-hexadecanoic acid, lupeol, and betulin were inferred as key antibacterial constituents. A comprehensive review of reported antimicrobial activities revealed distinct antibacterial spectra and intensities across the varieties, aligning with their unique liposoluble profiles. This study provides a systematic chemical profile of bast fibers and offers a predictive assessment of their antibacterial potential. The findings lay a chemical foundation for future targeted research and development of antibacterial materials derived from specific bast fiber varieties.
