Phylogenetic relationships within Celastraceae were inferred using a simultaneous analysis of 61 morphological characters and 1123 base pairs of phytochrome B exon 1 from the nuclear genome. No gaps were inferred, and the gene tree topology suggests that the primers were specific to a single locus that did not duplicate among the lineages sampled. This region of phytochrome B was most useful for examining relationships among closely related genera. Fifty-one species from 38 genera of Celastraceae were sampled. The Celastraceae sensu lato (including Hippocrateaceae) were resolved as a monophyletic group. Loesener's subfamilies and tribes of Celastraceae were not supported. The Hippocrateaceae were resolved as a monophyletic group nested within a paraphyletic Celastraceae sensu stricto. Goupia was resolved as more closely related to Euphorbiaceae, Corynocarpaceae, and Linaceae than to Celastraceae. Plagiopteron (Flacourtiaceae) was resolved as the sister group of Hippocrateoideae. Brexia (Brexiaceae) was resolved as closely related to Elaeodendron and Pleurostylia. Canotia was resolved as the sister group of Acanthothamnus within Celastraceae. Perrottetia and Mortonia were resolved as the sister group of the rest of the Celastraceae. Siphonodon was resolved as a derived member of Celastraceae. Maytenus was resolved as three disparate groups, suggesting that this large genus needs to be recircumscribed.
利用核基因组中来自 1123 个碱基对的 phyB 外显子 1 的 61 个形态特征和同时分析，推断 Celastraceae 内部的系统发育关系。没有推断出空位，基因树拓扑结构表明引物是针对单个基因座特异性的，而在取样的谱系中没有重复。phyB 的这个区域最有助于检查密切相关属之间的关系。从 Celastraceae 的 38 个属中采集了 51 个种。广义的 Celastraceae（包括 Hippocrateaceae）被解析为一个单系群。Loesener 的 Celastraceae 亚科和族没有得到支持。Hippocrateaceae 被解析为一个单系群，嵌套在一个并系的 Celastraceae stricto 中。Goupia 被解析为与 Euphorbiaceae、Corynocarpaceae 和 Linaceae 的关系比与 Celastraceae 的关系更密切。Plagiopteron（Flacourtiaceae）被解析为 Hippocrateoideae 的姐妹群。Brexia（Brexiaceae）被解析为与 Elaeodendron 和 Pleurostylia 密切相关。Canotia 被解析为 Celastraceae 中 Acanthothamnus 的姐妹群。Perrottetia 和 Mortonia 被解析为 Celastraceae 其余部分的姐妹群。Siphonodon 被解析为 Celastraceae 的一个衍生成员。Maytenus 被解析为三个不同的组，表明这个大属需要重新定义。
