ANTIOXIDANT, ANTIBACTERIAL AND GUT MODULATING ACTIVITIES OF KALANCHOE LACINIATA.

Kalanchoe laciniata (L.) DC. (Crassulaceae) is a widely distributed plant in Africa and Asia. Traditionally, various communities use this plant for the treatment of a variety of ailments such as gut prob- lems, allergic conditions and wounds. The current study was designed to explore the antibacterial, antioxidant and gut modulating activities of K. laciniata in order to provide scientific rationale for its traditional uses. Phytochemical compounds were assessed through screening 70% crude methanolic extract of K. laciniata. Its gut modulatory activity was evaluated by in vitro tissue experiments on rabbit jejunum which yielded maximal spasmogenic response of 28.4 ± 4.6% (n = 4) at 3 mg/mL, while spasmolytic response was recorded with EC50 value of 3.2 mg/mL (2.8-3.5, 95% CI, n = 5). In antibacterial assays crude extract was found effective against Stapllococcus aurus and Bacillus subtilis, with MIC value of 5 and 2.5 mg/mL, respectively. The testing of the methanolic crude extract for antioxidants resulted in total phenolic contents of 27.8 ± 1.8 mg GAE/g DW and 22.7 ± 2.1 mg AAE/g DW total antioxidant activity. It also scavenged 17.3 ± 3.0% of DPPH free radical when compared with quercitin.
