Genus Suaeda: Advances in phytology, chemistry, pharmacology and clinical application (1895 - 2021).

More than 100 species of annual herb genus Suaeda widely distribute (Asia, North America, northern Africa and Europe), are rich in resources (about hundreds of millions of tons/Y) and have a long historical application. Most of them are mainly used for traditional food, feed and medicine. Recently, they have been employed to repair saline-alkali land and beautify the environment. So far, only 27 species have been reported on the bioactivity diversity, broad spectrum and effectiveness in clinical practice. Therefore, the in-depth and extensive research of Suaeda has become a research hotspot around the world. However, only one review summarized the nutritional, chemical and biological values of Suaeda. By searching the international authoritative databases (ACS Publications, ScienceDirect, PubMed, Springer, web of Science and Bing International etc.) and collecting 103 literatures closely related to Suaeda (1895-2021), herewith a comprehensive and systematic review was conducted on the phytology, chemistry, pharmacology and clinical application, enveloping the classification evolution between Amaranthaceae and Chenopodiaceae, distribution and common botanical characteristics; involving 9 chemical categories of 163 derivatives covering 14 new and 6 first-isolated ones, and appraising the content determination of 6 categories of components; mainly including the pharmacology of 13 species in vivo and vitro; estimating the clinical application of 16 species cured the related diseases of eight human physiological system except for the motor system. It is expected that this paper will provide forward-looking scientific ideas and literature support for the further modern research, development and utilization of the genus.
