BACKGROUND In Iranian traditional medicine, gum obtained from Astragalus gummifer and some other species of Astragalus was used as analgesic agent. OBJECTIVE In this study, we investigated the antinociceptive effect of several concentrations (125, 250, and 500 μg/kg body weight) of Astragalus gummifer gum (AGG) on thermal and acetic acid induced pain in mice. MATERIALS AND METHODS AGG was d...

BACKGROUND The Astragalus gummifer (F. Fabaceae), herb and roots were studied for anti-inflammatory and hepatoprotective activities. MATERIALS AND METHOD The alcoholic extracts of Astragalus gummifer (F. Fabaceae), herb (AGHE), and roots (AGRE), were used for anti-inflammatory and hepatoprotective activities in Wister rats. The effects of AGHE and AGRE were compared with the standard drugs Ph...

Cycloastragenol (CAG) is a secondary metabolite isolated from Radix Astragali. Present in all known Astragalus spp., CAG (Fig. 1) is both a triterpene aglycone and the most common genuine aglycone in the bioactive triterpenoid saponins called astragalosides (ASTs) (Rios and Waterman, 1997). Although CAG and the ASTs are found in all tissues of the Astragalus shrubs, the highest concentrations a...

PREMISE OF THE STUDY Are there dimensions of symbiotic root interactions that are overlooked because plant mineral nutrition is the foundation and, perhaps too often, the sole explanation through which we view these relationships? In this paper we investigate how the root nodule symbiosis in selenium (Se) hyperaccumulator and nonaccumulator Astragalus species influences plant selenium (Se) accu...

Based on specimens in various museum collections one new subgenus and six new species of Elimaeini are described: Poaefoliana subgen. n. (type species Locusta poaefolia De Haan, 1842) of Elimaea Stål, 1874; Elimaea (Poaefoliana) albimaculata sp. n., E. (P.) jitra sp. n., E. (P.) kutu sp. n., Elimaea (Schizelimaea) singgalang sp. n., Orthelimaea kanburi sp. n., O. volsella sp. n. Three classical...

A list of world species for subgenera of Philosepedon Eaton, including Philosepedon s. str., Trichosepedon Krek, and Philothreticus Krek is given, and the subgenus Bahisepedon subgen. nov. is proposed to include some western hemisphere species. Philosepedon wagneri nom. nov. is proposed to replace P. orientale Wagner, a homonym of P. orientale Krek. Two new species from Europe, Philosepedon dum...

A new subgenus and new species of anophthalmic trechine beetles, Oodinotrechus (Pingleotrechus) yinae subgen. n., sp. n., is described and illustrated from a limestone cave called Chaotianyan in southern part of Guilin karst, northeastern Guangxi Zhuang Autonomous Region. The new taxon is very different from the Maolan-Mulun congeners belonging to the nominate subgenus Oodinotrechus (s. str.) U...

A group of 15 species from the genus Euphylidorea (Alexander, 1972) is identified based on distinct morphology and described as the new subgenus Neophylidorea. Characters of the aedeagus and male genitalia in general allow for unequivocal recognition of this subgenus. Comparisons among other species-groups within Euphylidorea and Neophylidorea subgen. n. Petersen are made. A new species, Neophy...
