Two new very-long-chain 5--alkylresorcinol (AR) homologues, that is, 5--nonacosylbenzene-1,3-diol and 5--hentriacontylbenzene-1,3-diol, were isolated from acetone extracts of samaras. These phenolic compounds were detected in nearly equal proportions, although their total content varied considerably between samples from urban-grown trees. No correlation was observed between AR levels and the physiological state of the tree, suggesting that environmental conditions may strongly influence AR biosynthesis in . Furthermore, the isolated AR mixture exhibited antifungal activity against soil-borne phytopathogens of the genera and .
从翅果的丙酮提取物中分离出两种新的极长链5-烷基间苯二酚（AR）同系物，即5-二十九烷基苯-1,3-二醇和5-三十一烷基苯-1,3-二醇。这些酚类化合物的检测比例几乎相等，尽管其总含量在城市种植树木的样本之间差异很大。未观察到AR水平与树木生理状态之间的相关性，这表明环境条件可能强烈影响AR的生物合成。此外，分离出的AR混合物对和属的土壤传播植物病原体具有抗真菌活性。
