C. ELDRIDGE Nonhern Regional Research Celller. Agricll/Illra/ Research. Science and Edllcmion Administration, U.S. Department of Agricll/llIre, 1815 North University Street, Peoria. 1L 61604 (U.S.A.; (Received July 27th, 1981) Soybeans are known to contain several isoflavones (daidzein, glycitein, genis tein) and isoflavone glucosides l (daidzin, glycitein-7-f3-0-glucoside, genistin) which 2 3 4 have been reported to have estrogenic , antifungal and antioxidant activity. The quantitative determination of soybean isoflavones has been reported by gas-liquid chromatography (GLC)l, and more recently high-performance liquid chromatogra phy (HPLC)5.6.7 has been used. Carlson and Dolphin5 separated soybean isoflavone aglycones present in an alcohol extract on a pPorasil column. The isoflavone glucosides were determined after hydrolytic treatment with aqueous acid. In a paper by West et al. 6 only two isoflavone aglycones from soybean extracts were separated. This communication reports the development of a procedure for the separation of the naturally occurring soybean isoflavone glucosides and isoflavone algycones using HPLC with mild solvents and reversed phase packing that may be less likely to catalyze decomposition compared to other packings. MATERIALS AND METHODS* A Waters Assoc. (Milford, MA, U.S.A.) HPLC system was used, comprised of a WISP 710A, M-45 solvent delivery system, Model 660 solvent flow programmer, Model 450 variable-wavelength detector, with a DuPont Zorbax ODS 25 x 0.46 cm 1.0. -

Rapid screening techniques for identification of active compounds from natural products are important not only for clarification of the therapeutic material basis, but also for supplying suitable chemical markers for quality control. In the present study, ultrafiltration combined with high performance liquid chromatography-mass spectrometry (HPLC-MS) was developed and conducted to screen and identify bovine serum albumin (BSA) bound ligands from Puerariae flos. Fundamental parameters affecting the screening like incubation time, BSA concentration, pH, and temperature were studied and optimized. Under the optimum conditions, nine active compounds were identified by UV and MS data. The results indicated that this method was able to screen and identify BSA bound ligands form natural products without the need of preparative isolation techniques. -

What Are Soy Isoflavones? Figure 2: Soy Isoflavones Reduced Plasma Isoprostanes Soy Isoflavones Are a Class of Natural Bioactive Compounds in Soybeans
TECHNICAL REPORT Purina Veterinary Diets® OM Overweight Management® brand canine dry formula and the Beneficial Role of Isoflavones Introduction Approximately 35% of adult dogs in the U.S. are overweight or obese1. A markedly greater incidence of overweight and obesity was observed in neutered male (59% higher) and female dogs (40% higher)1. Chronic obesity can increase the risk of, or complications from, several chronic diseases including diabetes, hypertension, pulmonary and cardiovascular disease, and degenerative joint disease2. Obesity produces chronic, mild inflammation and increases oxidative stress, which, in turn, contributes to the development of the above-mentioned chronic diseases.3,4 Therefore, reducing obesity and oxidative stress can promote a long life span and improved quality of life in dogs. What are Soy Isoflavones? Figure 2: Soy Isoflavones Reduced Plasma Isoprostanes Soy isoflavones are a class of natural bioactive compounds in soybeans. Natural a Marker of Oxidative Stress soy isoflavones include three chemical compounds: daidzein, genistein, 5 Plasma Isoprostanes (ng/ml) and glycitein. Many health benefits have been associated with regular consumption of soy products. In humans, soy has been found to reduce the 4 risk of cardiovascular disease and certain types of cancer (breast and prostate cancer); relieve a number of problems in post menopausal women including 3 hot flashes, osteoporosis, and decline in cognitive function; reduce cholesterol and triglycerides in plasma; improve symptoms of hypertension; and reduce 2 abdominal fat accumulation.5,6,7 1 Why Did Nestlé Purina 0 Control Isoflavones* Choose Isoflavones? *P<0.01 for Control vs. Isoflavones Soy isoflavones provide a number of benefits for managing dogs with obesity, and reducing rebound effects after weight loss. -
Changes of Phytoestrogens Daidzein, Genistein and Their Glycosides Daidzin and Genistin and Coumestrol During Processing of Soyabeans
Czech J. Food Sci. Vol. 22, Special Issue Changes of Phytoestrogens Daidzein, Genistein and Their Glycosides Daidzin and Genistin and Coumestrol during Processing of Soyabeans J. LOJZA*, V. SCHULZOVÁ and J. HAJŠLOVÁ Department of Food Chemistry and Analysis, Institute of Chemical Technology, Prague, Czech Republic, *E-mail: [email protected] Abstract: Phytoestrogens represent biologically active compounds showing estrogenic activity similar to that of sex hormones – estrogens. Various adverse effects such as sterility, increase of females’ genitals, lost of males’ copulation activity, etc. were observed in farm animals after exposure to higher amounts of fodder containing phytoestrogens. On the other side, their presence in human diet is nowadays the object of many research stud- ies concerned with prevention of breast and prostate cancer, osteoporosis and other hormone-linked diseases by dietary intake of phytoestrogens. Soya (Glycine max) is one of the main sources of these compounds in diet. Isoflavones daidzein and genistein occurring either free or bound in glycosides are the main phytoestrogens in this food crop. Coumesterol representing coumestans is another effective phytoestrogen contained in some ed- dible plants. In the first part of our study, analytical method for determination of free and total phytoestrogens was developed and validated. Following steps are included: (i) acid hydrolysis (only for “total phytoestrogens” analysis), (ii) extraction with methanol/water mixture, (iii) SPE preconcentration; (iv) identification/quantifica- tion using HPLC/DAD/FLD. The aim of present study was to document the fate of phytoestrogens and their forms during household/industrial processing. As documented in our experiments the most dynamic changes of phytoestrogen levels occur during soyabeans sprouting. -

In this study, we demonstrated that puerarin significantly improves glucose tolerance in C57BL/6J-ob/ob mice, an animal model of type 2 diabetes mellitus, blunting the rise in blood glucose levels after i.p. administration of glucose. In contrast, daidzin, the O-glucoside, had a significant but opposite effect, impairing glucose tolerance as compared to saline-treated controls. When they were administered i.p. with 14C-glucose to C57BL/6J lean mice, puerarin inhibited glucose uptake into tissues and incorporation into glycogen, while daidzin stimulated glucose uptake, showing an opposite effect to puerarin. Puerarin also antagonized the stimulatory effect of decyl-â-D-thiomaltoside, an artificial primer of glycogen synthesis, which increases 14C-glucose uptake and incorporation into glycogen in mouse liver and heart. A liquid chromatography-tandem mass spectrometry procedure was used to investigate the metabolism and bioavailability of puerarin and daidzin. The blood puerarin concentra- tion-time curve by i.p. and oral administration indicated that puerarin was four times more bioavailable via i.p. injection than via the oral route of administration. -

In the present study, capillary zone electrophoresis (CE) was applied for the separation and quantification of three isoflavones including daidzein, genistein and formononetin in coffee. Extraction of isoflavones from the coffee sample was carried out by extraction and purification process using ether after the acid hydrolysis with the antioxidant butylated hydroxy-toluene (BHT). The experimental conditions of the CE separation method were: 20 mmol/L Na2HPO4 buffer solution, 25 kV applied voltage, 3 s hydrodynamic injection at 30 mbar, and UV detection at 254 nm. The results show that the three compounds can be tested within 10 min with a linearity of 0.5–50 µg/mL for all three compounds. The limits of detection were 0.0642, 0.134, and 0.0825 µg/mL for daidzein, formononetin and genistein, respectively. The corresponding average recovery was 99.39% (Relative Standard Detection (RSD) = 1.76%), 98.71% (RSD = 2.11%) and 97.37% (RSD = 3.74%).
