Therefore, it is needed to replace the coloring agent with other bioavailable material to prevent the toxicity. Objective: to investigate whether red dragon meat extract (hylocereus costaricencis) pigment or anthocyanin can be a substi tute for erythrocin in disclosing agent, and determine the optimal concentration Methods: This study wil l compare the penetration strength in various concentration: 25%, 50%, and 75% dragon meat extract as well as disclosing solution on potato beam medium. Result: The 75% extract of red dragon meat was the most optimal concentration Conclusion: The 75% extract of red dragon meat can be used as substitute for disclosing solution.
