This research aims to increase the biological activities of natural syringaldehyde. The synthesis of syringaldehyde derivatives and controls the size of the material particles in the nanometer ranges. Nano-organic compounds (L1 - L2) and nano-organometallic compounds (C1 - C4) are used for the study of physicochemical characterization and biological activities. Antioxidant capacities were the DPPH and FRAP techniques, and bacterial abilities against Escherichia coli, Salmonella spp. and Staphylococcus aureus. The syringaldehyde salicylic hydrazone (L2) showed a high scavenging ability to DPPH. Free radical exhibited with IC<sub>50</sub> values as low as 51.109 ppm. The ability of antioxidants by FRAP showed that substances are capable of reducing Fe<sup>3+</sup> and most of C3, the ability to inhibit the growth of bacteria with the lowest MIC and MBC values and the ability to Chilo polychrysus (Meyrick) found that C1 and C2 showed LT<sub>50</sub> at 24 h and 48 h (19.00 and 19.33). These particles should develop as biological agents to reduce the use of chemicals that are harmful to humans and the environment.展开更多
