Viability Test of Water Hyacinth Leaf Extract (Eichornia Crassipes) on Human Gingival Fibroblast Cells

Abstract

Periodontal disease is a chronic inflammatory disease caused by colonization of bacteria that affects softtissues and hard tissues that support the teeth, inflammation and rejuvenation of alveolar bone are signsof periodontal disease. Fibroblast also play a role in producing and maintaining extracellular matrix, cellproliferation and cell differentiation in response to prolonged tissue injury and chronic inflammation. Thecomponents of water hyacinth are very beneficial for health such as phenols, alkaloids, flavonoids, tannins.This study aimed to determine the concentration of EcengGondok leaf extract which can maintain theviability of human gingival fibroblast cells for 24 hours. The method human gingival primary cell culturewas harvested, placed on a 96-well microplate. Each well on the microplate was given water hyacinth leafextract with a concentration of 1 mg/ml, 0.5 mg/ml, 0.25 mg/ml, 0.25 mg/ml, 0.125 mg/ml, 0.0625 mg/ml, 0.0312 mg/ml, 0.0156 mg/ml for 24 hours. MTT assay was carried out by adding MTT solution after24 hours of incubation. Formazan optical density values are read by ELISA reader with a wavelength of590 nm, viability is obtained by calculating the viability formula. Results are viability of human gingivalfibroblast cells was good starting in the treatment group 0.125 mg/ml, 0.0625 mg/ml, 0.0312 mg/ml and0.0156 mg/ml. Conclusion the highest viability of human gingival fibroblast cells in the treatment group of0.0156 mg/ml was 75.98%.
