EVALUATION OF IPIL-IPIL (Leucaena leucocephala) SEED GUM AS CO-ENCAPSULATING AGENT FOR TARGETED AND CONTROLLED DELIVERY OF POWDERED INSULIN PLANT (Chamaecostus cuspidatus)

Type 2 Diabetes Mellitus (T2DM) is the most common non-communicable disease in the Philippines, characterized by increased blood glucose levels brought by low insulin production or insulin resistance. Chamaecostus cuspidatus is a medicinal plant known for its glucose-lowering property. The controlled release of the C. cuspidatus leaves must be achieved to maximize its antidiabetic property. Leucaena leucocephala is an endemic tree in the Philippines, having its seed as a source of possible co-encapsulating material for drug delivery. Galactomannan, as the main component of the isolated seed gum, can be used as a substitute for an effective moderate drug release to its intended site. Thus, this study evaluates the drug release property and stability of seed gum as a co-encapsulating agent for targeted and controlled delivery of the C. cuspidatus leaves. The encapsulation process of the C. cuspidatus leaves was done through the extrusion method. The stability of the encapsulation was evaluated through in vitro gastrointestinal simulation analysis and was examined using differential scanning calorimetry (DSC), Fourier transform infrared spectrometer (FTIR), and field emission scanning electron microscope (FE-SEM) to verify its surface morphology. The capsules were observed to fully disintegrate at the fed state (pH 5.4) of the simulated gastrointestinal conditions, which is the target site. The fingerprint on the FTIR spectra of the encapsulated drug presented indicates the successful incorporation of the powdered leaves inside the encapsulating material. Morphological micrographs have shown that the resulting capsules were fairly in spherical, having a size of approximately 3.8 mm. Ridges and pores are also present on the surface of the capsules for their immediate disintegration and hydration. Therefore, the L. leucocephala seed gum can be a potential candidate as a co-encapsulating material suitable for effective, targeted, and controlled delivery of C. cuspidatus leaves for maximum antidiabetic benefits.
