Anthocyanin colors and factors which stabilize and enhance these labile pigments were studied in this thesis. Berry anthocyanin colors were successfully improved by phenolic acid and natural plant extract addition. The results obtained contribute to the understanding of the chemical behavior of anthocyanins. The color quality of black currant wine was improved by the addition of crowberry juice...

Significant antiviral activity against respiratory illness viruses has been found in a hot-water extract of black soybean. This black soybean extract showed significant antiviral activity against human adenovirus type 1 and coxsackievirus B1 in a dose-dependent manner, while the hot-water extract from common yellowish soybean showed only weak activity. The antiviral activity could not be extrac...

Drosophila models of tauopathies have been developed by transgenically overexpressing the disease-associated forms of tau. In this paper we report for the first time that a recently developed Grape-Seed Polyphenolic Extract (GSPE) improves the eye phenotype of a Drosophila eye model of R406W tau. GSPE-mediated improvements in this distinct in vivo neurodegeneration model for protein misfolding/...

Grape seed oil is rich in phenolic compounds, fatty acids, and vitamins, with economic importance to pharmaceutical, cosmetic, and food industry. Its use as an edible oil has also been suggested, especially due to its pleasant sensory characteristics. Grape seed oil has beneficial properties for health that are mainly detected by in vitro studies, such as anti-inflammatory, cardioprotective, an...

Objective The effect of 10% sodium ascorbate, 10% α-tocopherol, 10% grape seed extract, and 10% guava seed extract solutions on the shear bond strength (SBS) of composite resin to bleached enamel was evaluated. Materials and Methods Labial enamel surfaces of 72 extracted maxillary central incisors were bleached using 37.5% hydrogen peroxide. Sixty-four specimens were divided into four experim...

To investigate the modification of salivary pellicle with different polyphenol-rich teas and natural extracts for protection against dental erosion. We performed two experiments: one (Green tea, Black Peppermint Rosehip negative control [NC]) other (Grape seed, Grapefruit Cranberry, Propolis, NC), where NC was deionized water. A total 150 enamel specimens were used (n = 15/group). Both experime...

BACKGROUND E. faecalis is the predominant micro-organism recovered from root canal of the teeth where previous endodontic treatment has failed. Thorough debridement and complete elimination of micro-organisms are objectives of an effective endodontic treatment. For many years, intracanal irrigants have been used as an adjunct to enhance antimicrobial effect of cleaning and shaping in endodontic...

To investigate the hepatoprotective potential of ethanolinc grape seed extract on acetaminophen (APAP) induced liver toxicity in wistar rats. Silymarin was used as reference hepatoprotective agent. Liver injury was induced by APAP (2 gm/kg body weight, bw) on the 1st day of experiment. Vitis vinifera (V. vinifera)L seed extract (200 and 400 mg/kg bw) and silymarin (100 mg/ kg bw) was administer...

Grape seed contains many polyphenolic compounds that have potential health-promoting benefits. Among these compounds are proanthocyanidins, also known as condensed tannins, which is a class of flavanols. The basic structural building blocks of flavanols are polyhydroxyflavan-3-ol units linked together by C-C bonds. They are widely distributed in plants but grape seed has very high contents. Thi...
