Abstract

The Loteae tribe, a tribe within the subfamily Faboideae, is part to the large (> 20000 species) Fabaceae family. Some members of the Loteae have been used in traditional medicine. Here, we provide an overview of the specialized natural products identified in taxa belonging to the Loteae tribe until 2023. Over 360 secondary metabolites including flavonoids, isoflavonoids, terpenoids, steroids, and nitrogenous compounds have been found in members of the Loteae. However, the extend of research dedicated to the various genera and species within the tribe Loteae varies considerably thus limiting any systematic assessment of natural products as marker compounds.

Nontheless, the inclusion of the former genus Securigera into the genus Coronilla is supported by the similarities in the phytochemical composition. Cardenolides occur in the species Coronilla cretica L. and Coronilla scorpioides (L.) Koch as well as in some former Securigera species. Furthermore, the genera Dorycnium and Lotus show significant similarities in their flavonoid profiles, which is consistent with the inclusion of Dorycnium into Lotus.

This review of the existing literature on the Loteae tribe metabolites aims to provide a valuable basis for future studies on secondary metabolites. Studying the phytochemical profiles of the different taxa will allow a better understanding of their biological activities and potentially expand their use. Moreover, more clade/genus specific compound classes might be identified by dedicated future studies.

豆科植物的植物化学

芸香科（Loteae）是豆科（Faboideae）亚科中的一个科，属于豆科（Fabaceae）大家族（> 20000 种）。芸香科的一些成员已被用于传统医药。在此，我们概述了截至 2023 年在芸香科植物中发现的特殊天然产物。在芸香科植物中发现了 360 多种次级代谢产物，包括黄酮类、异黄酮类、萜类、甾体类和含氮化合物。然而，对芸香科内各属和种的研究范围差别很大，从而限制了对作为标记化合物的天然产品的系统评估。Coronilla cretica L.和 Coronilla scorpioides (L.) Koch 以及一些前 Securigera 属物种中都含有卡地诺内酯。此外，Dorycnium 属和莲属在其黄酮类化合物谱中显示出显著的相似性，这与将 Dorycnium 并入莲属是一致的。研究不同类群的植物化学特征将有助于更好地了解它们的生物活性，并有可能扩大它们的用途。此外，通过今后的专门研究，可能会发现更多的科/属特定化合物类别。

期刊介绍： Biochemical Systematics and Ecology is devoted to the publication of original papers and reviews, both submitted and invited, in two subject areas: I) the application of biochemistry to problems relating to systematic biology of organisms (biochemical systematics); II) the role of biochemistry in interactions between organisms or between an organism and its environment (biochemical ecology). In the Biochemical Systematics subject area, comparative studies of the distribution of (secondary) metabolites within a wider taxon (e.g. genus or family) are welcome. Comparative studies, encompassing multiple accessions of each of the taxa within their distribution are particularly encouraged. Welcome are also studies combining classical chemosystematic studies (such as comparative HPLC-MS or GC-MS investigations) with (macro-) molecular phylogenetic studies. Studies that involve the comparative use of compounds to help differentiate among species such as adulterants or substitutes that illustrate the applied use of chemosystematics are welcome. In contrast, studies solely employing macromolecular phylogenetic techniques (gene sequences, RAPD studies etc.) will be considered out of scope. Discouraged are manuscripts that report known or new compounds from a single source taxon without addressing a systematic hypothesis. Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
