Abstract: From the alcoholic extract of stem bark of Polygala arillata, fifteen compounds including the derivatives of oligosaccharide esters, xanthones, lignans, phenols and aliphatic acids were isolated. Among them, seven new compounds were named as arillanin A (3), B(6), C(7), D(4), E(5), F(8) and G (11), respectively; methyl 1-0-α-L- arabinopyranosyi (6→ 1 ) - β - D - glucopyranosyi salicylate (9) as a new salicylic acid derivative, also first isolated from plants. All structures of isolated compounds were i-dentified by means of spectral data, especially 2 - D NMR experiments.
