Various dosage forms were prepared from the crude drug, coming from Lagerstroemia speciosa (L.) Pers. or "banaba" and pharmaceutico-chemical and pharmacological studies were done on them. Thin-layer chromatography of all dosage forms showed the presence of Beta-sitosterol except the fluid-extract prepared using 50% ethyl alcohol. Fluid extracts using 95% and 50% ethyl alcohol produced a diuretic effect in rats while petroleum ether and ethyl ether extracts showed an anti-inflammatory activity in mice.
