Abstract
Context: Parkia speciosa is a species which contains hydrophilic compounds such as flavonoids and phenolics. These compounds are difficult to penetrate lipophilic biological membranes. Transfersome is a targeted dosage form that can overcome the limitations of phytomedicine.
Aims: To improve the ability of extracts to penetrate biological membranes.
Methods: Transfersome was formulated with soya lecithin and Tween-80 as independent variables using factorial design 32. The influence of factor compositions and factor interactions on transfersome characteristics was observed based on efficiency absorption percentage (%EE), polydispersity index (PDI), stability, and pH.
Results: Analysis with DX® 10 produced optimum formula with 0.85 g of lecithin and 0.15 g of tween-80. The optimum formula characteristics’ results analysis was as follows: %EE (91.6884 ± 0.0261%), particle size (495.6 nm), PDI (0.484), and zeta potential (-21.4 mV) and spherical vesicle shape. Stability testing showed that transfersome was more stable compared to the pure extracts. Diffused transfersome percentage (6.6253 ± 0.5817 %) on the minute 360 was better than the pure extracts (1.8800 ± 0.0187 %). Compartmental transfersome analysis with WinSAAM™ software followed lag compartment model (p<0.05). Interaction test using FTIR showed that there was no chemical interaction between extract and excipients.
Conclusions: The finding result in this investigation shows that transfersome loaded with ethanol extract of Parkia speciosa is more stable and more easily diffused compare to the pure extract.
