Insufficient detoxification and/or overproduction of reactive oxygen species (ROS) induce cellular and tissue damage, and generated reactive oxygen metabolites become exacerbating factors of dermatitis. Keishibukuryogan-ka-yokuinin (KBGY) is a traditional Japanese medicine prescribed to treat dermatitis such as acne vulgaris. Our aim was to verify the antioxidant properties of KBGY, and identif...

The mineral contents of Centaura leave and seeds were determined by Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES). Macro element concentrations (P, K, Ca, Mg and S) of samples were found at high levels. K was established at high level in both leave and seed samples of Centaurea. While K contents of leaves changes between 7254.10 mg/kg (Centaurea lycaonica) and 26396.36 m...

Pyrogallol, as an important chemical raw material and reagent, has been prepared by the decarboxylation reaction of gallic acid hydrolyzing tannin acid extracted from Chinese gall, but the decarboxylation reaction is known to cause serious environmental pollution. To obtain efficient strains to degrade gallic acid, a screening study was carried out to explore different strains and optimal ferme...

Lung cancer, breast cancer and colorectal cancer are the most prevalent fatal types of cancers globally. Gallic acid (3,4,5-trihydroxybenzoic acid) is a bioactive compound found in plants and foods, such as white tea, witch hazel and it has been reported to possess anticancer, antioxidant and anti-inflammatory properties. In this study we have redesigned our previously reported anticancer nanoc...

The antioxidant potential of the 99% methanolic extract of leaves of Muntingia calabura was assessed by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and total phenolic content was measured by Folin-Ciocalteau (FC) by Singleton and Rossi using Gallic acid and Tannic acid as the calibration standard. Moreover Muntingia calabura leaf extract showed strong reducing power and significant antioxidant a...

The present study is done to examine and optimize the process of enzyme-assisted extraction of Gallic acid from the dried fruit of Emblica officinalis. The aqueous extraction yielded 12.09% of Gallic acid. A selective extraction process after the treatment with enzymes is proposed by using 30% (v/v) methanol which releases up to 15.68% of the Gallic acid, present in the dried fruit. The optimal...

Free radicals and reactive oxygen species are generated in the body due to various physiological and biochemical processes. They are responsible for various chronic diseases like cancer, diabetes and oxidative damage of DNA and proteins. There is a huge demand of herbal antioxidant compounds in the market. Padaeria foetida,Tribulus terrestris and Oxalis corniculata are used in traditional healt...

A new type of chitosan/2-hydroxypropyl-β-cyclodextrin composite membrane have been developed for the encapsulation and controlled release of gallic acid. The morphology of the composite membrane was investigated by infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM), whereas swelling gallic acid and release properties were investigated by UV-visible spectroscopy. The release be...
