Abstract

Antioxidative effects of Taheebo extract, obtained from the bulk of Tabebuia avellanedae Lorents and Griseb, were examined by two assay methods for radical scavenging activity on DPPH and inhibitory effect on linoleic acid peroxidation. In the case of the DPPH method, Taheebo showed the electron donating ability to DPPH and its ability corresponded to that of trolox in the present experimantal condition. On the other hand, in the autoxidation of liloleic acid, Taheebo extract showed the most inhibitory effect in teas tested (green tea and oolong tea.). These results suggested that Taheebo extract was a desirable antioxidant.
