13. Estudos sobre dormência de Euphorbia dracunculiodes e Astragalus spp.: principais ervas daninhas das zonas áridas
O objetivo deste estudo foi analisar o comportamento de dormência de Euphorbia dracunculoides e Astragalus spp., ervas daninhas de grão de bico árido. Tratamentos de quebra da dormência foram: ácido Gibberalic (GA3) e tioureia cada a 50, 100 , 150 , 200 , 250 e 300 ppm e de nitrato de potássio ( KNO3 ) em 5.000, 10.000, 15.000 , 20.000, 25,000 e 30,000

14. Synthesis and evaluation of artificial antigens for astragaloside IV
The objective of this study was to produce artificial antigens for astragaloside IV that could be used to prepare antibodies against astragaloside IV screened in Radix astragali (Astragalus membranaceus (Fisch) Bunge, Fabaceae) and its preparations, using an indirect ELISA. Astragaloside IV was coupled to carrier proteins, bovine serum albumin and ovalbumin

15. Anti-candidal activity of Astragalus verus in the in vitro and in vivo guinea pig models of cutaneous and systemic candidiasis
This study was design to evaluate the anti-candidal activity of Astragalus verus Olivier, Fabaceae (Av). The GC/MS analysis of essential oils of Av showed that aqueous extract contains thymol while hexadecanoic acid, 1,2-benzenedicarboxylic acid, diisooctyl ester and phytol were found as major components of methanol and acetone extracts. The aqueous extract

16. Constituintes químicos de Astragalus annularis Forssk. and A. trimestris L., Fabaceae
A investigação química das partes aéreas de Astragalus annularis Forssk. e A. trimestris L., Fabaceae, do Egito, resultou no isolamento de oito compostos, pela primeira vez nestas duas espécies. Estes compostos foram identificados por métodos químicos, espectroscopia de RMN, espectroscopia UV, bem como análise de EM. A atividade antimicrobiana dos co

17. Flavonoids in Astragalus corniculatus
Nine flavonoids were identified in aerial parts of Astragalus corniculatus Bieb. (Fabaceae) by liquid chromatography coupled with ionspray mass spectrometry in the tandem mode (LC/MS/MS) with negative ion detection. Vitexin, orientin and eriodictyol-7-O-glucoside are obtained for the first time in genus Astragalus L, and isorhamnetin-3-O-glucoside in the spe

18. Intoxicação por Sida carpinifolia (Malvaceae) em caprinos
Descrevem-se os achados clínicos e patológicos da intoxicação espontânea e experimental por Sida carpinifolia em caprinos. Os achados da intoxicação espontânea serão apresentados em dois artigos. Um deles relata pela primeira vez uma doença investigada em de 1997 no município de Lajeado, RS. O outro artigo descreve os aspectos clínicos e patológ

19. In Vitro Incorporation of Selenomethionine into Protein by Astragalus Polysomes 1
Selenium-accumulator plants synthesize selenium compounds that differ from those produced by nonaccumulators. To determine if there are any subcellular differences between accumulators and nonaccumulators in the use of selenomethionine in vitro, polysomes from Astragalus crotalariae (accumulator) and Astragalus lentiginosis (nonaccumulator) were translated i

20. Selenium Absorption by Excised Astragalus Roots 1
Absorption of selenate and selenite by excised roots of Astragalus Crotalariae, a selenium accumulator, and of A. lentiginosus, a non-accumulator, was favored by CaCl2 and a pH of 4.0. The uptake of selenate and possibly selenite, is metabolically linked. Roots of a number of Astragalus species were examined, and in all cases selenate entered the roots much

21. Exclusion of Selenium from Proteins of Selenium-Tolerant Astragalus Species 1
Protein fractions from three selenium-tolerant and three selenium-sensitive Astragalus species, grown in the presence of [75Se]selenate, were analyzed for their selenium content. Though tolerant species are known to accumulate considerably more selenium than do sensitive plants, protein fractions from the three selenium accumulators were found to contain sig
