PREPARATION OF THE EXTRACTS AND THEIR BIOLOGY ACTIVITIES FROM DIANELLA ENSIFOLIA

Abstract

Preparation of four extracts from Dianella ensifolia (n-hexane, chloroform,
ethyl axetate, buthanol) by extraction method. Investigating the biological
activity of the hexane, ethyl axetate, buthanol extracts showed many remarkable
activities: the hexane and buthanol extracts have activity to inhibit NO
production and not toxic to cells in both concentrations 3µg/mL and 10µg/mL
tests, especially at 10µg/mL of inhibitory capacities of the ethyl axetate and
buthanol extracts are 71.74% and 65.22% respectively; Two extraction residues
(the ethyl axetate, buthanol extracts) are both antioxidant at a concentration of
500µg/mL, of which the ethyl axetate extract with IC50 = 107.40 ± 2.06µg/mL.
