Abstract

Nanoparticles are used in drug delivery which can increase mass transfer so increase the absorption and effectiveness of the drug. Therefore, its prospect to improve antibacterial and antioxidants activities of betel leaves. The research aimed to preparation and characterization of betel leaf extract using ionic gelation technique. The formulation of nanoparticles from betel leaf extract with ionic gelation method using alginate and CaCl2 with a ratio of 2.5: 1. The characterization of the nanoparticles includes particle size analysis, zeta potential, particle morphology and determination of flavonoid content. Particle size analysis demonstrated that the betel leaf extract nanoparticles had a particle size of 243,03 ± 1,48 nm, zeta potential of -23,0 ± 0,35 mV and morphology of particle showed that a flat shape. The betle leaf exctract nanoparticle positively contained flavonoid with Rf 0.7 equivalent to quercetin. The betel leaf extract can be made nanoparticles with ionic gelation method using alginate and CaCl2.

Abstract

Sappan wood ( Caesalpinia sappan L.) contains brazilin including isoflavonoids which act as antimicrobials (against bacteria on skin) and antioxidants. Nano technology increases surface area, enhance stability, reduces skin irritation, protects from degradation, and has good drug delivery. Nano emulsion preparations can help permeability of the drug on the membrane surface. Nanoemulgel preparations can provide stability and good drug release compared to mixing drugs directly in a gel base. The purpose of this study were to determine the effect of different concentrations of CMC-Na gelling agents and which concentration of CMC-Na gelling agents that can produce the best nanoemulgel preparations. Nanoemulsion made from isopropyl myristate as oil phase, tween 80 as surfactant and polyethylenglycol as co-surfactant. Nanoemulsion formulations were tested by measurement of % transmittance by UV-Vis spectrophotometry at a wavelength 650nm. Nanoemulgel is made from nano emulsions used basis of CMC-Na at concentrations 3%, 4%, and 5%. The results showed percent transmittance was 71.86%. The results of physical quality and stability tests of the nanomulgel wood preparations showed an influence on the physical properties such as adhesion, dispersion and viscosity, the greater concentration of CMC-Na gelling agents in nanoemulgel preparations, the greater values adhesion and viscosity, while the spreadability was smaller. Concentration of CMC-Na gelling agent that produced the best of sappan wood nanoemulgel ( Caesalpinia sappan L.) was 5% that stable by freeze-thaw testing.
