		abstract={Nanoparticles are very small material coating technique, with an average
diameter of 1-1000 nm. Flavonoid have a low bioavailability the caused by low
solubility in water and absorption is limited to the gastrointestinal and intestines.
Nanoparticles have been shown to be able to increase the bioavailability of the
low solubility drug in the systemic circulation. The aim of this research is
preparation and characterization of the betel leaf nanoparticles which include
particle size, zeta potential, particle morphology, as well as qualitative analysis of
flavonoid content. Preparation of nanoparticles with ionic gelation method using
alginic acid polymer of 0.1% and CaCl2 0.02%. Characterization of nanoparticle
size using Particle Size Analysis (PSA) indicates the particle size 276,36±56,70
nm. The morphology of nanoparticles with Scanning Electron Microscopy (SEM)
indicates the particle is not spherical. The potential zeta value used the Zetasizer23 ± 0.35mV. Qualitative analysis by thin-layer chromatography (TLC) indicates
presence flavonoid between the initial extract of the betel leaf and nanoparticles
are made of betel leaf extract.}
