1. ISOFLAVONOIDES DA TRIBO DALBERGIEAE: UMA CONTRIBUIÇÃO QUIMIOSSISTEMÁTICA PARA A SUBFAMÍLIA PAPILIONOIDEAE
Plants from Fabaceae family have several secondary metabolites and high biological potential. The subfamily Papilionoideae (Fabaceae) has 28 tribes, of which Dalbergieae comprises 49 genera and 1325 species. Isoflavonoids are chemotaxonomic markers of Papilionoideae and have important biological properties. This review describes the isoflavonoids and biologi

2. Phenolic Composition and Leishmanicidal Activity of Red Propolis and Dalbergia ecastaphyllum (L.) Taub (Fabaceae) Extracts from Sergipe, Brazil
ABSTRACT Leishmaniasis is a parasitic disease caused by protozoa of the Leishmania genus. It may manifest in visceral and tegumentary forms, and pentavalent antimonials are the first choice drugs used for the treatment. Frequently these drugs show low efficiency and high toxicity to mammalian host. The present study describes the chemical profile and the in

3. 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

4. Anti-inflammatory activity and chemical analysis of extracts from Trifolium riograndense
Abstract Aiming to investigate new therapeutic agents with fewer side effects, the number of studies about natural products has increased. Phenolic compounds comprise a well-studied class of abundant plant-derived compounds, whose anti-inflammatory activity has been described. Isoflavones are phenolic compounds that occur mainly in the Leguminosae family, an

5. Isoflavone formononetin from red propolis acts as a fungicide against Candida sp
Abstract A bioassay-guided fractionation of two samples of Brazilian red propolis (from Igarassu, PE, Brazil, hereinafter propolis 1 and 2) was conducted in order to determine the components responsible for its antimicrobial activity, especially against Candida spp. Samples of both the crude powdered resin and the crude ethanolic extract of propolis from bot

6. Chemical markers and antifungal activity of red propolis from Sergipe, Brazil
The aim of this study was to analyze the physicochemical properties and antifungal activities of the red propolis samples from Sergipe, Brazil, and also evaluate their variability throughout the year. The characterization of the hydroalcoholic extract (HPE) of the red propolis samples was performed monthly from October 2009 to September 2010. The concentrati

7. Anti-psoriatic activity of flavonoids from Cassia tora leaves using the rat ultraviolet B ray photodermatitis model
The plant Cassia tora L., Fabaceae, traditionally, is claimed to be useful in the treatment of psoriasis and other skin diseases. In order to evaluate this information, antipsoriatic activity of three flavonoids, namely luteolin-7-O-β-glucopyranoside (1), quercetin-3-O-β-D-glucuronide (2) and formononetin-7-O-β-D-glucoside (3), isolated from the ethanol e

8. Modulatory activity of brazilian red propolis on chemically induced dermal carcinogenesis
PURPOSE:To evaluate modulatory effects of a hydroalcoholic extract of Brazilian red propolis (HERP) on dermal carcinogenesis using a murine model.METHODS: The HERP was used at concentrations of 10, 50 and 100 mg/kg (PROP10, PROP50 and PROP100, respectively) to modulate dermal carcinogenesis induced by the application of 9,10-dimetil-1,2-benzatraceno (DMBA) o

9. Genetic variability of isoflavones in the USDA red clover core collection
Red clover is one of the most utilized forage in agriculture and contains many of the isoflavones known for their human health benefits. The objectives of this study were: i) to quantify, using HPLC analysis, isoflavones in 77 accessions from the USDA core collection and a Brazilian line; ii) to verify possible relationships depending on their origin, improv

10. In vitro isoflavonoid production and analysis in natural tetraploid Trifolium pratense (red clover) calluses
Isoflavones are polyphenolic phytoestrogens, predominantly found in leguminous plants. Trifolium pratense L., Fabaceae (red clover), is rich in isoflavones that possess estrogenic activity due to their similar molecular structure and effectiveness in preventing health conditions such as menopause, osteoporosis, cardiovascular disease, hypertension and hormon

11. In vivo and in vitro anti-inflammatory activity of red clover Trifolium pratense dry extract
Red clover Trifolium pratense L., Fabaceae, contains four isoflavones, mainly formononetin and biochanin A, and in smaller concentrations, daidzein and genistein. These compounds have gained a lot interest due to its human health benefits, such as estrogenic and progestogenic activities, antioxidant, anti-cancer and others. The objective of this study was to

12. Isolation and identification of formononetin of João Pessoa-PB-Brazil red propolis, seasonal studies and evaluation of their biological activities / Isolamento e identificação de formononetina da propolis de João Pessoa - PB, estudo de sua sazonalidade e avaliação de suas atividades biologicas
Propolis is a resinous substance produced by the honeybee Apis mellifera. Bees use propolis to seal holes and to protect the beehive. To produce propolis the honeybee uses resins of leaf buds and buds, resinous exudates and other parts of plant tissues. Propolis is used as a folk medicine since 3000 BC. Numerous biological properties have been found includin
