Abstract

|
|
The present study was carried out to investigate the potential acute toxicity of bamboo leaf water extract by a single oral dose in Sprague-Dawley rats. Twenty male and female rats aged 5 weeks were randomly assigned to four groups of 5 rats each and were administered singly by gavage at dose levels of 0, 1250, 2500, or 5000 ㎎/㎏ body weight. Mortalities, clinical findings, and body weight changes were monitored for the l4-day period following the administration. At the end of 14-day observation period, all animals were sacrificed and complete gross postmortem examinations were performed. Throughout the study period, no treatment-related deaths were observed. There were no adverse effects on clinical signs, body weight, and gross finding at any dose tested. The results showed that the single oral administration of bamboo leaf water extract did not induce any toxic effect at a dose level of below 5000 ㎎/㎏ in rats and that the minimal lethal dose were considered to be over 5000 ㎎/㎏ body weight for both sexes.
