Memorandum Of Understanding between Mahsa University Malaysia and Institut Ilmu Kesehatan Bhakti Wiyata Kediri Indonesia - RESEARCH REPORTS INTERNATIONAL RESEARCH COLLABORATION "FORMULATION AND EVALUATION OF ANTIBACTERIAL ACTIVITY OF EMULGEL PREPARATION CONTAINING MUNTINGIA CALABURA L. LEAVES EXTRACT"

Background and aims: Acne develops due to the obstruction Of pilosebaceous follicles by accumulated sebum, keratinocytes, and microbial colonization Certain secondary metabolites from plants possess anti - acne properties, including karsen (Muntingia calabura This study aims to formulate and evaluate the anti-acne activity Of an emulgel against Propionibacterium acnes. The ethanolic extract from Muntingia calabura L. leaves was used in the formulation. Methods: The extraction process was carried out using maceration. The ethanolic extract Of karsen was utilized as the active ingredient in the emulgel formulation. The emulgel was evaluated based on its organoleptic properties, homogeneity, PH, emulsion type, spreadability, and adhesion. The antibacterial activity was assessed through an in vitro antibacterial assay. Results: The extraction yield was 10.8%. The extract contained flavonoids, tannins, and saponins. The formulated emulgel had a semi-solid consistency, a brownish-green color, a distinct Odor characteristic Of Muntingia calabura L. leaves, and was homogeneous. It had a pH range Of 4.87—5.40, an oil-in-water (O/W) emulsion type, a spreadability Of 5.1—5.8 em, and an adhesion time Of 3.26—4.36 seconds. The formulation exhibited anti-acne activity against Propionibacterium acnes, with the highest inhibitory activity observed at a concentration Of 12%. Conclusion: The ethanolic extract from M. calabura L. leaves can be successfully formulated into a stable emulgel. The formulated emulgel exhibits antibacterial activity against Propionibacterium acnes.
