Some of the aqueous extracts were further fractionated by shaking with chloroform to eliminate chloroform-soluble substances or passed through and aluminium oxide column. The precipitated tannin from some fractions was redissolved in a small amount of water and also tested for active compound(s). Acidic ion- exchanger was also used to fractionate the aqueous extracts. The different fractions so prepared, altogether twenty-two, were tested for hypotensive activity on dogs anaesthetized with barbiturates.สาระสังเขป: It was observed that the hypotensive activity was most pronounced in the basic fraction from the ion- exchanger column. The aqueous extracts from leaves had a more pronounced hypotensive effect than the extracts from the stems and this effect was not reduced by chloroform extraction. Authors, modified
