Caesalpinia ferrea MART. (Leguminosae) called as Juca is one of the medicinal plants in Brazil used for diabetes. From the fruits of this plant, ellagic acid (EA) and 2-(2,3,6-trihydroxy-4-carboxyphenyl)ellagic acid (TEA) have been recently isolated as aldose reductase (AR) inhibitors. In this study, we examined to prove the inhibitory activity against AR of EA and TEA in vitro, and EA in vivo ...
Tulare walnut, a cultivar highly resistant to aflatoxin formation, was investigated for endogenous phytochemical constituents capable of inhibiting aflatoxigenesis in Aspergillus flavus. The activity, located entirely in the pellicle (seed coat), was extractable to various degrees with polar solvents, although some activity remained unextractable, indicating that the bioactivity resided in a co...
Hageman factor (factor XII) is activated by exposure to surfaces such as glass or by solutions of certain compounds, notably ellagic acid. Changes in the structure of Hageman factor accompanying activation have been examined in this study by circular dichroism spectroscopy. The spectrum of unactivated Hageman factor in aqueous solutions suggests that its conformation is mainly aperiodic. Variou...
In this study the in vitro activities of seven antibiotics (ciprofloxacin, ceftazidime, tetracycline, trimethoprim, sulfamethoxazole, polymyxin B and piperacillin) and six phytochemicals (protocatechuic acid, gallic acid, ellagic acid, rutin, berberine and myricetin) against five P. aeruginosa isolates, alone and in combination are evaluated. All the phytochemicals under investigation demonstra...
BACKGROUND Even facial pigmentation is considered a universal sign of youth and beauty in all cultures and at all ages in both men and women. The recent FDA concern about the safety of topical hydroquinone has provided the impetus for research into new pigment lightening alternatives in the cosmetic OTC market. AIM This research examined a novel hydroxyphenoxy propionic acid, ellagic acid, ye...
To address the ever increasing resistance of pathogens and need of safer preservatives for food products, herbs are being explored for antimicrobial properties. Methanolic extract of Fennel (Foeniculum vulgare Miller) was analyzed for the presence of polyphenolic compounds, flavonoids and antibacterial potential. The extract, rich in flavonoids (9.325 ± 1.25 mg QE/g dry seeds) was subjected to ...
There is a growing need for short-term assays which can assess the mechanisms and efficacy of cancer chemopreventive agents. In the present study we have employed a microsome-mediated test system concomitantly with DNA adduct detection to assess the efficacy of five chemopreventive agents, N-acetylcysteine, butylated hydroxytoluene (BHT), curcumin, oltipraz, and ellagic acid. 32P-Postlabeling a...
