Physical Properties and pH Environment of Foam Dressing Containing Leaf Extract and Gelatin.

has several biological activities, including antibacterial and anti-inflammatory activities, that improve wound healing. It is well known that physical properties and pH environment are crucial considerations when developing wound dressings containing medicinal plant extracts in order to create an appropriate environment for wound healing. In this study, we prepared a foam dressing containing leaf extract and gelatin. Chemical composition was verified using Fourier-transform infrared spectroscopy (FTIR) and pore structure was obtained using scanning electron microscopy (SEM). The physical properties of the dressing, including absorption and dehydration properties, were also evaluated. The chemical properties were measured to determine the pH environment after the dressing was suspended in water. The results revealed that the dressings had a pore structure with an appropriate pore size (313.25 ± 76.51 µm and 383.26 ± 64.45 µm for the A and B dressings, respectively). The B dressings showed a higher percentage of weight increase in the first hour and a faster dehydration rate in the first 4 h. Furthermore, the dressings had a slightly acidic environment (5.28 ± 0.02 and 5.38 ± 0.02 for the A and B dressings at 48 h, respectively).
