The phenolic compound had been isolated from ethyl acetate fraction from the bark of tembesu (Fragraea fragrans Roxb) by stationer phase were the gel silica G 60 (70 - 230 mesh). Spectroscopy showed the phenolic compound had three units aromatic and aldhyde group. The phenolic compound inhibited microbial growth : Bacillus subtilis, Staphylococcus aureus, Pseudomonas aurugenosa, Shigella dysent…
Synthesis of silver nanoparticles using tembesu bark extract (Fagraea fragrans) and antifungal tests on fungi that infected mango plants have been carried out. Making AgNPs through variations in the volume of the tembesu bark extract and temperature, the best volume of tembesu bark extract whichwas 5 mL and the best temperatureof AgNPs is at 70oC. The results of the analysis FTIR on tembesu bar…
