Plants gums are complex mixtures of different polysaccharides with a variety of biological activities and pharmaceutical applications. Few studies have focused on physicochemical and biological properties of gums obtained from different plants. This study was designed to determine potential pharmaceutical and pharmacological values of the gum exudates and its isolated biopolymers obtained from ...

The genus Prosciara from China is reviewed and 36 species are recognized. Among them, 16 new species, P. oligotricha sp. nov., P. gyracantha sp. nov., P. hemicrypta sp. nov., P. angusta sp. nov., P. euryacantha sp. nov., P. ellipsoidea sp. nov., P. paucispina sp. nov., P. myriacantha sp. nov., P. columellata sp. nov., P. fossulata sp. nov., P. ternidigitata sp. nov., P. globoidea sp. nov., P. l...

The petiole and rachis anatomy of II North American Astragalus species that show a tendency towards persistent petioles is described and illustrated by line drawings of representative transections. The results are compared with those of a spine anatomical survey of 200 Old World Astragalus and Astracantha species. Attention was given to the anatomical characters previously determined to be taxo...

Astragalus, as the largest genus of flowering plants, is well-known for its high species richness and morphological diversity. Previous studies suggested that many subgenera Astragalus are not monophyletic phylogenetic relationships within still poorly known. In this study, we sampled 117 accessions close relatives, covering 55 sections plus 30 outgroup taxa to recover main clades eastern Asian...
