Evaluation of acute toxicity and intestinal transit time of Olax scandens Roxb. leaves.

ABSTRACT

INTRODUCTION: Olax scandens Roxb. is a shrub or small tree found throughout tropical India. Fruits and leaves of this plant are used for medicinal and food purpose. Traditionally, leaves of O. scandens are used as vegetable in constipation. AIM: To evaluate the acute toxicity and intestinal transit time of O. scandens leaves on experimental animals. MATERIALS AND METHODS: Acute oral toxicity study for sample was carried out following OECD guidelines. Evaluation of intestinal transit time was carried out in the dose of 1300 mg/kg by adopting Kaolin expulsion test and latency of the onset of kaolin expulsion in fecal matter in mice. RESULTS: The results show that the test drug is not likely to produce any toxicity in higher dose. In kaolin expulsion test, the drug produced mild increase in intestinal motility in mice proved by fast clearance of kaolin pellet in comparison to control group. CONCLUSION: The leaves of O. scandens are safe at higher dose and showed mild laxative activity in the dose of 1300 mg/kg body weight of mice.
