Abstract

The family Sapindaceae are tropical and sub-tropical continental plants. In this study, terephthalic acid bis-(2-ethylhexyl) ester (1) and phthalic acid bis-(2-ethylhexyl) ester (2) were isolated as isomeric compounds from the ethanolic leaf extracts of Deinbollia pinnata for the first time together with methyl gallate (3), ethyl gallate (4), and pyrogallol (5). The separation of the isomeric mixture was by freezing the sub-fraction with methanol for seventy-two hours; followed by filtration, isolation, and purification.
