Abstract :
Kemangi leaves contain flavonoid compounds. Flavonoid compounds
contained in basil can be used as hepatoprotectors. Flavonoid compounds have low
solubility in water so that the dissolution rate and bioavailability is low. The ethanol
extract of basil leaves is made as a suspension because it can cover up the bitter
taste of the extract and to make it easier for patients who have difficulty taking
tablets or capsules. Making suspension preparations is important for the addition of
suspending agents, one of the suspending agents used is xanthan gum. The purpose
of this study was to determine the effect of the concentration of xanthan gum
suspending agent on the physical properties of suspension of basil leaf extract with
a concentration variation of 0.2%; 0.3%; 0.4%. Suspension physical test is carried
out by evaluating suspension preparations which include organoleptic,
homogeneity, pH, density, viscosity, precipitation, redispersibility, and displaced
volume. The test results using xanthan gum as a suspending agent produced a stable
suspension during stability testing for 4 weeks. Formula 2 with a concentration of
xanthan gum suspensions of 0.3% was chosen as the best formula based on physical
quality and suspension stability with a pH of 4,4, viscosity 1.5 d.Pas, displaced
volume 100%, density 1.0927, no sediment and no redispersion time.
