Abstract :
Flavonoids contained in bay leaves (Eugenia polyantha) are a class of compounds
that can lower blood glucose levels. The solubility of flavonoids itself is low in
water accompanied by a short filling time in the small intestine so as to provide
low absorption and often causes problems for medical applications. Therefore
patch preparations were made to increase their bioavailability because patches do
not experience a first pass effect in the liver and provide consistent delivery over a
long period of time. The extract of bay leaves was made by maceration and
patches were made with variations of PVP K-30 and Ethyl Cellulose 1: 2 and 1: 3.
Bay leaf extract patch preparations were tested for physical properties including
organoleptic, uniformity, pH, drying loss, thickness, homogeneity, folding
resistance, aseptability test and stability test for 21 days. The results of the
physical properties test for transdermal patch preparations showed that with a
concentration of PVP K-30: Ethyl Cellulose 1: 2 bay leaf extract can produce
good physical properties on the parameters of oragnoleptic, homogeneity, weight
uniformity, pH, drying loss, thickness, folding resistance, and aseptability. The
difference in the concentration of PVP K-30 and Ethyl Cellulose, the variation
concentration of PVP K-30 and Ethyl Cellulose with a ratio of 1: 2 resulted in
good physical properties, namely weight uniformity with an average (0.25 ±
0.0058), folding resistance ( > 300), thickness (0.03 ± 0), drying shrinkage (0%),
ph (5 ± 0), and aseptability were obtained mean values (3.8).
