Blume) is an Indonesian medicinal plant that has various pharmacological properties. Zebrafish (Danio rerio) has been proposed as a model that can bridge the gap between cell assays and rodent assays. Evaluation of the toxic effects of natural products using the Zebrafish model can be assessed starting from the blastula stage of embryonic development. This study aims to investigate the potential acute toxicity effect of keladi tikus-ethanol extract (KTEE) using zebrafish embryos. A static non-replacement regime for acute toxicity testing was used. Wild-type zebrafish embryos were exposed to various concentrations of KTEE (50, 100, 200, 400, 800, 1600 μg/mL) starting at 6 hours post-fertilization (hpf) until 96 hpf. The results showed that the survival rate of zebrafish embryos decreased as the concentration of the test extract increased. The LC50 values of KTEE were 494.553 μg/mL at 96 hpf and 555.787 μg/mL at 72 hpf. Embryotoxicity effect of KTEE includes hatching delays and decreased heartrate on zebrafish embryos, especially at high concentrations. KTEE also caused abnormalities in embryo morphology, including pericardial edema, jaw and tail deformity.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Acute toxicity,Ethanol extract,Keladi tikus,Zebrafish embryo[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The first author would like to thank the Indonesian Endowment Fund for Education (LPDP) that has supported his studies and this research.
