1951年，首次进行了对Hopea odorata（thingan）心材的提取。沸腾的轻质石油除去了未进一步研究的蜡质物质，随后的乙醚萃取得到棕色固体（7%），其通过从丙酮-乙酸中结晶而最好地纯化，然后得到藜芦酚（约10%）。1%）为无色晶体。后来通过类似的提取Balanocarpus heimii（chengal）获得了相同的材料。这两种植物都是原产于东南亚的龙脑香科植物，并且对于是否应该将chengal与Hopea属合并存在争议。Chengal和各种Hopea物种是达玛树脂的来源，近年来已被广泛研究。发生同样的非常不寻常的提取物在chengal和在一个Hopea可能会加强viewla，有一个单独的BaZanocarpus属的理由很少。自1951年最初的隔离，一直断断续续的工作，但进展受到阻碍的经典方法的燃烧分析和分子量测定，以确定苯酚或其衍生物的分子式。最近的质谱分析结果表明，藜芦酚的分子式为C56 H42 O 12，其中10个氧原子以羟基形式存在。调查工作正在进行中，但鉴于问题的复杂性，现在似乎应该报告该大院的存在，该大院似乎是一种独特的类型，以及早些时候的调查结果。
THE extraction of the heartwood of Hopea odorata (thingan) was first carried out in 1951. Boiling light petroleum removed waxy materials which were not further investigated, and subsequent ether extraction gave a brown solid (7%) which was best purified by crystallisation from acetone-acetic acid and then gave hopeaphenol (ca. 1%) as colourless crystals. The same material was later obtained by a similar extraction of Balanocarpus heimii (chengal). Both of these plants are Dipterocarpaceae indigenous to South East Asia, and there has been dispute as to whether chengal should be merged with the Hopea genus. Chengal and various Hopea species are the source of dammar resins which have been extensively investigated in recent years. The occurrence of the same very unusual extractive in chengal and in a Hopea might reinforce the viewla that there is little justification for a separate BaZanocarpus genus.Since the original isolation in 1951, there has been intermittent work on hopeaphenol but progress has been hindered by the inability of classical methods of combustion analysis and molecular weight determinations to define the molecular formula of the phenol or its derivatives. Very recently mass spectrometry showed conclusively that hopeaphenol has the formula C56H42012, and that ten of the oxygen atoms are present as hydroxyl groups. Investigations are proceeding but, in view of the complexity of the problem, it seems proper to report now the existence of the compound, which appears to be of a unique type, and the results of the earlier investigations.
