Hepatoprotective activity of Mentha rotundifolia aqueous extract against hepatocellular damage induced by CCL4 in rats.

This study aims to assess hepatoprotective properties of M. rotundifolia. Decoction was used to prepare the aqueous extract. The preliminary cytotoxicity evaluated against Caco 2 and RAW 264 cells demonstrate no cytotoxic effect. The preventive impact of the extract against liver damage was evaluated by examining blood levels of AST, ALT, ALP, total proteins, and histological alterations in liver tissues. Thirty albino rats were separated into five groups: the first served as normal group, the second was injected by olive oil (3 ml/kg), and the third was injected by CCL4 (3 ml/kg). However, groups IV and V received daily doses of 250 and 500 mg extract/kg bw, respectively before CCL4 injection. The results showed that the administration of the extract led to a marked improvement in plasma biochemical markers and a reduction in symptoms of CCL4-induced liver damage. The extract exhibits hepatoprotective activity, which may be attributed to its phytochemical components.

Isofraxisecoside, a new coumarin-secoiridoid from the stem bark of Fraxinus xanthoxyloides.

A new coumarin-secoiridoid diglucoside, named Isofraxisecoside, was isolated from the stem bark of Fraxinus xanthoxyloides (G. Don) Wall. ex A. DC. along with nine known compounds. The structure of new compound has been determined on the basis of 1H, 13C, 2D NMR and HRMS methods.
