Abstract

Diabetes mellitus is a global health challenge, necessitating the need for alternative treatments. Croton zambesicus Muell Arg. (Euphorbiaceace) a medicinal plant used traditionally in the treatment of some ailments was investigated for its inhibitory potential on alpha-amylase and alpha-glucosidase enzymes in rats. The root extract of C. zambesicus (27 - 81 mg/kg) was investigated in vivo for the inhibitory effect on alpha amylase and alpha glucosidase enzymes using starch, sucrose, and maltose as substrates. Acarbose was used as a reference drug. Blood glucose levels (BGL) of rats, post administration of the substrate and extract concurrently, were monitored over 3 hours as a parameter to measure the inhibitory potential of the extract. The root extract dose-dependently caused significant (p<0.05) reduction in blood glucose levels of treated rats with the various substrates used. The results suggest that the root extract of Croton zambesicus has the potentials to inhibit alpha amylase and alpha glucosidase in rats.

Abstract

Telfairia occidentalis Hook (cucurbitaceae) seeds, which is used in the preparation of soups and as medicine traditionally to treat various diseases by the Ibibios was investigated for effect against doxorubicin-induced hepatotoxicity. The seed extract (138 -553 mg/kg) and fractions; dichloromethane (DCM) and aqueous, 276 mg/kg) were evaluated for hepatoprotective activity against doxorubicin-induced liver injury in rats. Liver function parameters, liver oxidative stress markers and liver histology were used to assess the liver protective potential of the extract and fractions. The seed extract and fractions significantly (p<0.05-0.01) reduced the serum levels of AST, ALT, ALP, total and direct bilirubin that were elevated by doxorubincin. Also, the reduced levels of total protein and albumin by doxorubicin were increased by the extract coadministration. The levels of GSH, GST, SOD, GPx, and CAT that were decreased by doxorubicin were significantly (p<0.01) elevated and raised MDA level was reduced by the seed extract and fractions. Histology of the liver sections of extract -treated animals showed reductions in the pathological features compared to the organotoxic-treated animals. The chemical pathological changes were consistent with histopathological observations suggesting marked hepatoprotective potential. The anti-toxic effect of this plant may in part be mediated through the chemical constituents of the plant. The seeds of Telfairia occidentalis possess anti-toxicant properties which can be exploited in the treatment of doxorubicin related toxicities.
