已从Garcinia virgata的茎皮中分离出两种氧杂蒽酮，即virgataxanthone A和B，以及两种甲酰化生育三烯酚和已知的δ-生育三烯酚，griffipavixanthone和2，6-二羟基-4-甲氧基二苯甲酮（cotoin）。它们的结构主要是通过一维和二维NMR和质谱确定的。当有足够的材料时，评价粗提物以及分离的化合物的抗氧化活性。(C)2004爱思唯尔有限公司保留所有权利。
Two xanthones, namely virgataxanthone A and B, have been isolated from the stem bark of Garcinia virgata, together with two formylated tocotrienols and the known delta-tocotrienol, griffipavixanthone and 2,6-dihydroxy-4-methoxybenzophenone (cotoin). Their structures were mainly established using one and two-dimensional NMR and mass spectroscopies. When sufficient material was available, the antioxidant activities of the crude extracts as well as the isolated compounds were evaluated. (C) 2004 Elsevier Ltd. All rights reserved.
