ABSTRACT

Traditional herbs like Tinospora cordifolia and curcumin have many therapeutic benefits. However, curcumin’s limited bioavailability is a problem. Electrospun nanofibers are an answer because they increase the effective surface area greatly, and make drug delivery better in almost all aspects. The combination in the form of nanofibers can be greatly useful in the treatment of diabetic wound healing, where curcumin, the known antibacterial and anti-inflammatory element, plays an important role. It is observed that when combined with extract of leaves of T. cordifolia, which has known antidiabetic and wound healing actions, blended in the chitosan polymer, which is itself a weak antibacterial compound hence can be one of the solutions to the menace of bacterial resistance which is very common in diabetic wound healing. This research aims to create and test electrospun nanofiber mats of curcumin and T. cordifolia leaves extract blended in chitosan as a base polymer in the treatment of diabetic wound healing. Leaves of the plant T. cordifolia, which were collected from the institute’s botanical garden, were subjected to drying and then prone to solvent extraction using methanol and acetone, resulting in the production of bioactive extracts. The curcumin was obtained as a gift sample from Sanjay Chemicals, Mumbai. Nanofibers were electrospun from chitosan, T. cordifolia leaf extract and curcumin. Characterization included scanning electron microscope (SEM), water contact angle measurement, TGA/DSC analysis, drug release studies, fourier-transform infrared (FTIR) analysis, swelling tests and in-vitro release profiling. The nanofiber mats of curcumin and leaves extract of T. cordifolia using chitosan as a base polymer were prepared and evaluated at various parameters. The results we found are very promising. The nanofibers formed by using electrospinning techniques show good content uniformity as well as good diameter which was checked using SEM. The study confirmed no component interactions using differential scanning calorimetry (DSC). The good hydrophilicity of mats was found to ensure good retention time. The study concluded with the formation of a novel formulation that can fight the menace of bacterial resistance, which is very common in the diabetic wound healing process. The formulation will ensure not only countering bacterial resistance but also the faster healing of diabetic wounds, as T. cordifolia leaves extract is known to improve angiogenesis and tissue remodeling.
