The Preliminary Chemical and Experimental Pharmacological Study on the Leaves

and the Stems of Callisia fragrans

The preliminary chemical and experimental pharmacological study on the leaves and the stems of Callisia fragrans (Lindl.) Woods. revealed that:

- The leaves and the stems contained flavonoid, carotenoid, phytosterol, organic acid, fatty oil, polysaccharid and free sugars.

- Aqueous leaves extract and ethanol-aqueous stems extract at dose of 50g fresh material/ kg body weigh could not reduce experimental oedema induced by carrageenin in rats.

- Aqueous leaves extract and ethanol-aqueous stems extract have in vitro antibacterial effect against Staphylococcus aureus.

- Leaves and stems extract caused death in mice after a high oral single dose with LD₅₀ = 2430 g fresh material/kg body weigh.

Keywords: Callisia fragrans (Lindl.) Woods., acute toxicity, antibacterial effect.
