Optimizing the extraction of antibacterial compounds from pineapple leaf fiber

Abstract Five different solvents (petroleum ether, chloroform, ethyl acetate, acetone, and distilled water) were used to extract antibacterial compounds from pineapple leaf fiber. Compounds extracted using acetone showed the greatest antibacterial effect against Escherichia coli, measured by inhibition zone diameter. Three extraction parameters including temperature, time and solid-liquid ratio were optimized through orthogonal experiment based on single factor investigations for achieving maximum active substance extraction rate and bacteriostatic effect. Results showed that using acetone, the optimum extraction conditions for temperature, time and solid-liquid ratio were 45°C, 8 h, and 1:40 (g/ml), respectively.

Research on Performance of Pineapple Leaf Fiber Healthy Underwear

quick dryness Abstract. With pineapple leaf fiber as the raw material, refined dry jute is obtained through refined processing, which is blended with cotton to trail-produce 30S pineapple leaf fiber/cotton (30/70) blended yarn. Through the combination of industry, university and research and by cooperating with the textile enterprises, pineapple leaf fiber healthy underwear is researched, developed and trial-produced, and its water absorption and quick dryness are examined. The results show that the water absorption and moisture permeability of pineapple leaf fiber underwear reach the indicators of national textile standard, which provides a theoretical basis for the research and development of other pineapple leaf fiber products in the following.
