Abstract
The potential toxicity effect presents in the medicinal plants is important to be identified for
the safety assurance. Accute toxicity study is an initial step in the drug safety assurance test.
Thus, the aim of this study is to identify the potential acute toxicity of roots, stems, leaves,
and flowers ethanol extracts of bamboo bamboo plants (Polygonum pulchrum Blume). This
study used brine shrimp lethality test (BSLT) method. The total number of larvae used in
each concentrations in three times replications was 330 larvae. Each group was given consecutively
roots, stems, leaves and flowers ethanol extracts of P. pulchrum Blume plants with
variation concentrations 12.5 μg/ml, 25 μg/ml, 50 μg/ml, 100 μg/ml, 125 μg/ml, 250 μg/
ml, 500 μg/ml, 1000 μg/ml, 2000 μg/ml, and 4000 μg/ml. The number of dead larvae after
24 hours treatment were calculated to obtain the mortality percentages and to determine the
LC50 value, which were determined by probit analysis using MiniTab application version
17.1.0. Ethanol extract of P. pulchrum roots and stems resulted LC50 values of 933.08 μg/ml
and 919.58 μg/ml, respectively. While the LC50 values of leaves and flowers extracts were
2207.06 μg/ml and 1081.90 μg/ml, respectively. In conclusion, P. pulchrum Blume roots and
stems were classified as toxic according to BLST method, while leaves and flowers were not.
