Abstract

One type of antioxidant that is usually found in plants such as fruit, skin, leaves, and others is flavonoids. In addition, flavonoids can be used for the formation of nanoparticles (NPs) as a bioreductor. The purpose of this study was to examine the utilization of red dragon fruit peel extract as a bioreductor in the synthesis of zinc oxide nanoparticles from zinc nitrate precursors using the biosynthesis method. Red dragon fruit peel was macerated to obtain flavonoids. Zinc nitrate was used as a precursor to make ZnO NPs. UV-VIS spectrophotometric analysis showed that the total flavonoids contained in the extract were 5.6 x 10-4 mg QE/g. By FTIR test, ZnO nanoparticles are known to contain OH groups characterized by a peak in the 3374.10 cm-1 region. XRD results show that ZnO nanoparticles have a hexagonal wurtzite shape. SEM-EDX results show that the ZnO nanoparticles formed have a size of 157-174 nm and contain the constituent composition of 69.41% zinc and 29.35% oxygen. ZnO nanoparticles have anticancer effects that can be used in anticancer drugs, which can efficiently suppress synergistic cytoxicity in leukemia cell lines under UV irradiation.

Abstract

ZnO nanoparticles can be synthesized using the biosynthesis method using corn plant leaf extract (Zea Mays L.) as a bioreductant. The aim of this research is to examine the effect of variations in Zinc Nitrate Hexahydrate precursor concentration and calcination temperature on the yield, as well as the characterization of ZnO nanoparticles. Corn plant leaves are extracted to obtain flavonoid compounds. The resulting extract is mixed with the precursor solution then calcined to obtain ZnO nanoparticles.  The highest yield was produced in a sample with a precursor concentration of 0.1M with a calcination temperature of 300˚ C of 22.6082%. SEM-EDX results on samples with a precursor concentration of 0.3 M and a calcination temperature of 700˚C show various particle morphologies and sizes of ZnO nanoparticles, namely 91 nm; 97 nm; 109 nm; 435nm; and 973 nm, and the composition of ZnO nanoparticles consists of 76.43% Zn atomic weight and 23.57% O ​​atomic weight. at a calcination temperature of 700˚ C shows a pure ZnO sample with an element composition of 80.3% Zn atomic weight and 19.7% O atomic weight. The size of the crystal diameter for XRD analysis on samples with a precursor concentration of 0.3M with calcination temperatures of 300 ˚C and 700˚ C were 40.8564 nm and 31.7203 nm, respectively. Both samples have the same crystal system, namely hexagonal zincite.

Abstract

Nanocrystalline cellulose (CNC) was successfully synthesized from banana sheath waste and demonstrated promising potential for applications in biocomposites, sustainable materials, and biomedical fields. This study aimed to produce CNC through an environmentally friendly chemical process while investigating the effects of bleaching temperature and acid concentration on CNC yield and properties, in accordance with ISO/TS 20477:2017. The process involved delignification using 17% NaOH at 100°C for 1.5 hours to remove lignin, followed by bleaching with 10% H₂O₂ for 1.5 hours at various temperatures (70°C–90°C) to enhance cellulose purity. Acid hydrolysis using H₂SO₄ at concentrations of 10%–30% was conducted at 45°C for 40 minutes to break down amorphous regions and form nanocrystalline structures. Chesson-Datta analysis revealed cellulose, hemicellulose, and lignin contents of 80.32%, 5.257%, and 3.26%, respectively. Optimal conditions were found at 80°C bleaching temperature and 10% acid concentration, yielding 2.5606 g of CNC. SEM-EDX analysis showed smooth fibrous morphology with 63.55% carbon and 35.83% oxygen content, while XRD analysis indicated particle sizes ranging from 8.76 to 24.12 nm, with an average of 14.25 nm.
