1. Increased polyphenols and antioxidant activity of rice bean (Vigna umbellata L.) sprouts induced by Methyl Jasmonate: the promotion effect of Methyl Jasmonate on rice bean sprouts
Abstract Rice bean (Vigna umbellata L.) sprouts are richer in metabolites and biological activities after germination. The total polyphenol and total flavonoid contents were analyzed during the sprouting process. The antioxidant activities of the sprouts were tested using 1,1-diphenyl-2- picrylhydrazyl radical (DPPH) screening assay. To determine the reason

2. Isoflavonoid composition and biological activity of extracts from soybean seedlings treated by different elicitors
Abstract Time-course and dose-response experiments were carried out to establish the ability for synthesizing isoflavonoids of soybean seedlings (cv. Soyica P34) treated with salicylic (SA) and isonicotinic acids (INA). Then, 25 structurally-related compounds were evaluated for their isoflavonoid-eliciting activity. Next, the antimicrobial and antioxidant ac

3. Anti-inflammatory and antioxidant activities of the Impatiens noli-tangere and Stachys officinalis polyphenolic-rich extracts
ABSTRACT This study evaluated the anti-inflammatory and antioxidant activities of Impatiens noli-tangere L., Balsaminaceae, and of Stachys officinalis L., Lamiaceae, polyphenolic-rich extracts obtained by nanofiltration process. Results showed the great potential and efficiency of the nanofiltration process to concentrate the herbal extract's main polyphenol

4. Flavonoid profiling and nodulation of some legumes in response to the allelopathic stress of Sonchus oleraceus L.
Annual sowthistle (Sonchus oleraceus) has been reported to produce allelopathic effects. Two greenhouse experiments were conducted to estimate the allelopathic potential of both plant residue and root exudates of S. oleraceus on flavonoid composition and nodulation in a leguminous crop, Trifolium alexandrinum, and in two leguminous weeds, Melilotus indicus a

5. Development of an analytical method to quantify total isoflavones in phytotherapic capsules using high-performance liquid chromatography
Isoflavones can be found in grains and leaves of soybean. Currently, these are sold in pharmacies as phytotherapic capsules. Isoflavones have been recommended by doctors, especially for women, due to their ability to relieve menopause symptoms, among other benefits. However, no method exists for the official control of isoflavone content in capsules sold in

7. Avaliacao de cultivares de soja quanto aos teores de isoflavonoides.
Foram avaliados, por cromatografia liquida de alto desempenho (HPLC), os teores de isoflavonoides de 100 cultivares de soja (Glycine max (L.) Merrill), do banco de germoplasma do Centro Nacional de Pesquisa da Soja (CNPSO/EMBRAPA), semeadas na safra 1993-94. FT-Canarana, UFV-9, BABR-31 e FT-13, apresentaram os menores teores de isoflavonoides (16,78; 22,26;

9. Effects of genetics and environment on isoflavone content of soybean from different regions of Brazil.
The effects of genetics and environmental factors on isoflavone content of soybean (Glycine max L.) cultivars grown in different locations in Brazil in 1993/94 were evaluated. Seeds of different cultivars were analised by high performance liquid chromatography (HPLC). In Rio Grande do Sul (RS), Parana (PR), and Mato Grosso do Sul (MS) States, a significant d

12. Environmental and genetic variation of isoflavone content of soybean seeds grown in Brazil.
Abstract ? The objective of this work was to evaluate isoflavone concentrations in seeds of different Brazilian soybean cultivars grown in a range of locations and environmental conditions in Brazil. Seeds of 233 cultivars grown in Ponta Grossa, PR, Brazil, during the 2001/2002 soybean season, and of 22 cultivars sown in different locations of Brazilian Nort
