Bacteria, thallophytes, and seed plants (107 species), supplied with exogenous indole-3-ethanol (tryptophol), formed one or more of the following metabolites: O-acetyl tryptophol, an unknown tryptophol ester (or a set of structurally closely related esters), tryptophol glucoside, tryptophol galactoside, indole-3-acetic acid (IAA), and indole-3-carboxylic acid. The unknown ester was formed by all species examined; O-acetyl tryptophol appeared sporadically in representatives of most major taxonomic groups. Tryptophol galactoside was found in the algae Chlorella, Euglena, and Ochromonas. The glucoside was formed by many eucaryotic plants, but not by bacteria; it was a significant tryptophol metabolite in vascular plants. IAA, if detectable at all, was usually a minor metabolite, as should be expected, if tryptophol oxidase responds to feedback inhibition by IAA. Indole-3-carboxylic acid, formed by a few fungi and mosses, was the only tryptophol metabolite detected which is likely to be formed via IAA.
细菌、藻类植物和种子植物（107种），在供应外源吲哚 - 3 - 乙醇（色醇）的情况下，形成了以下一种或多种代谢产物：O - 乙酰色醇、一种未知的色醇酯（或一组结构密切相关的酯）、色醇葡萄糖苷、色醇半乳糖苷、吲哚 - 3 - 乙酸（IAA）和吲哚 - 3 - 羧酸。所有检测的物种都形成了未知酯；O - 乙酰色醇在大多数主要分类群的代表中偶尔出现。在小球藻、眼虫藻和赭球藻中发现了色醇半乳糖苷。葡萄糖苷由许多真核植物形成，但细菌不形成；它是维管植物中一种重要的色醇代谢产物。如果能检测到IAA，通常它是一种次要代谢产物，正如预期的那样，如果色醇氧化酶对IAA的反馈抑制有反应。由少数真菌和苔藓形成的吲哚 - 3 - 羧酸是检测到的唯一可能通过IAA形成的色醇代谢产物。
