Abstract

Ethanol extracts of the fruits of three kinds of Capsicum showed similar potencies in their antimicrobial activities against Gram (+) and Gram (-) bacterias, and fungi, although they contained different level of capsaicin. Bioautographic tests demonstrated that capsaicin was the main antimicrobial component. At least two other non-polar components of ethanol extract also contributed in the antimicrobial activity and very likely that these compounds were responsible for the activity toward Pseudomonas aeruginosa.

Abstract

Hypoglycemic activity of hexane, ethylacetate, ethanol and aqueous extract of Andrographis paniculata herbs had been tested using glucose tolerance test. Extraction was conducted consecutively using hexane, ethylacetate and ethanol. Aqueous extract was obtained directly from the crude drug similar to the traditional use. At the dose level of 0.5 g/kg bw, hexane and ethylacetate extract did not show the hypoglycemic effect. Significant activity was shown by ethanol and aqueous extract and the activity of the latter was higher than the former.

Abstract

Hypotensive and antihypertensive effect of fractions of ethanolic extract of “kucai” (Allium schoenoprasum L., Liliaceae) bulb had been tested on male Wistar rats. The ethyl acetate, n-buthanol and aqueous fractions of both fresh and dry bulb had hypotensive and antihypertensive effects. The aqueous fraction of fresh bulb at a dose of 25 mg/kg body weight showed the highest hypotensive and antihypertensive activities. The n-buthanol fraction of dry bulb at a dose of 50 mg/kg body weight showed the highest hypotensive activity. The ethyl acetate fraction of dry bulb at a dose of 50 mg/kg body weight showed the highest antihypertensive activity.
