초록

Background: Cassia tora L., an annual or perennial plant of the Fabaceae family, is traditional medicine with various biological activities, including anti-constipation and, anti-inflammation. Chemical compounds such as anthraquinone glycoside and naphthalene derivatives have been isolated from this plant. Cassia tora L. is a common contaminant of agricultural commodities, but is toxic to cattle and poultry.
Methods and Results: To investigate the potential toxicity, Cassia tora L. aqueous extract (CO) was administered orally to rats for 26 weeks at 0 (control), 300, 1,500 and 3,000㎎/㎏/day (n = 10 for male rats for each dose). The positive control comprised animals orally administered anthraquinone 100㎎/㎏/day. There was no treatment-related mortality. An increase in the kidney weight was observed at 3,000㎎/㎏/day of CO and anthraquinone 100㎎/㎏/day. Macrophage infiltration in the colon was observed at CO 1,500 and 3,000㎎/㎏/day and anthraquinone 100㎎/㎏/day, but there were no significant toxicological changes in the incidence and severity of the finding.
Conclusions: The oral no-observed-adverse-effect level (NOAEL) of CO was 3,000㎎/㎏/day in male rats and no target organs were identified. In addition, 300㎎/㎏ was found to be the no-observed-effect level (NOEL) for systemic toxicity under the conditions of the study.
