除已报道的大花木珊瑚中的生物碱外，还分离到了一些新的氧化吲哚生物碱，其中3个为新化合物。它们被命名为米曲叶碱、异米曲叶碱和异花叶碱。苦参碱A和B均为首次从植物中分离得到，而紫草素和紫草素为首次在该属植物中发现。对13个月的叶片样品的检查表明，在整个采收期内，三叶草碱和青藤碱仍然是成熟植株的主要吲哚生物碱。
In addition to the previously reported alkaloids from M. speciosa, a number of additional oxindole alkaloids were isolated, 3 of which are new. These were named mitrafoline, isomitrafoline and isospeciofoline. Mitragynine oxindoles A and B were found for the first time in plant material while corynoxeine and the corynoxines were found for the first time in the genus Mitragyna. Examination of 13 monthly samples of leaves showed that mitragynine and paynantheine remained the dominant indole alkaloids of the mature plant throughout the entire period of collection.
