Antimalarial, Antioxidant Activities and Chemoprofile of Gerome and Labroy (Agavaceae) Leaf Extract.

BACKGROUND

Gerome and Labroy (Agavaceae) is a religious and ornamental perennial plant with highly valued medicinal usage in Nigeria. Sansevieria liberica is used in the management of malarial fever. The ease of development of resistance to available antimalarial drugs has resulted in increased clinical failure and mortality. The study investigated the antimalarial effects of (SL) leaf extract in mice infected with .

MATERIALS AND METHODS

The ability of SL leaf extract to suppress the growth of malaria parasites in early (suppressive) and established (curative) infections was established using animal models. The mean survival time (MST) was determined. The antioxidant potential was established using two standard models. High-performance liquid chromatography (HPLC) and phytochemical analysis methods were used to create a chemoprofile fingerprint of SL hydroethanolic leaf extract.

RESULTS

At 200, 400, and 400·mg kg, SL produced 68.71, 70.74, and 75.09% parasite suppression in the suppressive model while the curative model gave a percentage of cure of 71.09, 72.60, and 62.09, respectively. The animals lived longer compared to both negative and positive controls but were not fully protected. The IC values of SL and vitamin C were calculated to be 3.599 g mL and 3.08 g mL, respectively. The reducing power of vitamin C was significantly ( < 0.05) higher than that of SL extract. Some flavonoids were established as possible marker compounds for SL leaf extract. . The antimalarial assay results demonstrated that the use of SL in folk medicine may have scientific support.
