Terpenoids of methanol extract of<i>Clerodendrum infortunatum</i>exhibit anticancer activity against Ehrlich’s ascites carcinoma (EAC) in mice

Abstract

Treatment with MECI causes significant decrease in the tumor cell volume and increase in the life span. The median survival time (MST) of EAC control group was found as 19.42 ± 0.91 d, whereas the MST was increased to 23.44 ± 2.69 d and 27.57 ± 2.57 d for the groups treated with MECI at 100 and 200 mg/kg, respectively. All the hematological parameters, malonaldehyde content and antioxidant enzymes' activity were restored towards the normal level. IC(50) value of MECI was found as 498.33 µg/mL in cytotoxicity study. The experimental results suggested that MECI has significant anticancer activity, which can be attributed to the presence of oleanolic acid and clerodinin A.
