Acute Toxicity Test of Zebrafish, Antifungal and Antibiofilm Activity of Etlingera rubroloba A.D Poulsen against Candida albicans

The Etlingera rubroloba A.D Poulsen (E.rubroloba) plant is empirically used as a joint pain reliever, wound and fungus medicine by the people of Southeast Sulawesi. This plant has never been reported regarding toxicity and biofilm against C. albicans, but other activities have been reported previously. This study aims to determine the acute toxicity of ethanol extract of Etlingera rubroloba using zebrafish, antifungal and antibiofilm activity against C.albicans, using 5 concentration of 625, 1250, 2500, 5000 and 10000µg/mL.The results of the acute toxicity test ethanol extracts of stems, fruits and rhizomes, respectively to LC50 3898.23, 10310.52 and 4065.10µg/mL based on probit analysis. The highest inhibitory values in antifungal (10,000µg/mL) were stem, fruit, rhizome and nystatin at 80.28; 81.98; 81.53 and 80.99, respectively. In the antibiofilm test, the highest inhibition value at 24 hours MBIC was in the stem, fruit, rhizome and nystatin as a positive control, respectively 77.83; 77.66; 78.42 and 78.62. Then at 48 hours MBIC were 74.9, 74.63, 73.80 and 74.82, respectively. The conclusion of this study is that the stem and rhizome category is slightly toxic and the fruit is practically non-toxic, and has activity as an antibiofilm of C. albicans. © RJPT All right reserved.
