Abstract
Background: Cardiovascular diseases (CVDs) are a leading cause of death, and their pathogenesis is commonly attributed to thrombosis. Although existing medications are effective and fast-acting for thrombosis management, they tend to be expensive and cause severe side effects. Plant-based thrombolytic agents are actively sought after as inexpensive and safe alternatives for the treatment and prevention of thrombosis. Red ginger (Zingiber officinale var. rubrum) and white ginger (Zingiber officinale var. officinale) are widely used in foods and beverages and are believed to confer a wide variety of health benefits. Objective: This study aims to elucidate the thrombolytic and fibrinolytic potential of red and white ginger extracts in vitro.Methods: In this study, in vitro analyses were performed using erythrocyte liberation, euglobulin degradation, fibrin degradation, and fibrin zymography assays. The ability of crude enzyme extracts from both red (rgEx) and white ginger (wgEx) to degrade blood clots was analyzed using the erythrocytes liberation assay. Then, the thrombolytic and fibrinolytic activities of rgEx and wgEx were evaluated using euglobulin and fibrin degradation assays, both of which were visualized using Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis (SDS-PAGE). Finally, fibrinolytic enzymes were identified using a fibrin zymography assay. Results: Red and white ginger extracts were found to have strong thrombolytic properties via high total liberated erythrocyte count from the erythrocyte liberation assay. The ginger extract proteases can rapidly degrade euglobulin and fibrin, with their priority order beginning with A
