The chemical components and antioxidant activity of 16 Rehmannia glutinosa samples were investigated to reveal the high-quality raw resource for pharmaceutical products. 22 main chemical components were detected with significant content differences (P<0.05). The contents of 14 substances reached
Compounds with antioxidant activity may protect different elements of blood from damaging effects of oxidative stress. The present in vitro study was designed to examine the antioxidant activity of methanolic extracts from leaves and roots of R. glutinosa plants against damages induced by oxidative
BACKGROUND
Traditional formulae usually exhibit therapeutic effects through the combinations of different ingredients. The purpose of this study was to investigate in vitro anti-oxidative activity of Thanh Hao Miet Giap Thang (THMGT) (Sweet Wormwood and Tortoise Shell Decoction) formula and the
Steamed roots of Rehmannia glutinosa (R. glutinosa) have been traditionally used in Oriental medicine for the treatment of auditory diseases such as tinnitus and hearing loss. To investigate whether the ethanol extract of steamed roots of R. glutinosa (SRG) increases activity of antioxidant enzymes
The antioxidant activity of methanolic extracts derived from shoots (HR-shoots) and roots (HR-roots) of pRi-transformed Rehmannia glutinosa plants were determined. The activity was indicated by the ability of the plant extracts to inhibit superoxide anion (O2(-·)) generation and thiobarbituric acid
The roots of Rehmannia glutinosa (RG) have been widely used for medicinal purposes in Asia. The traditional processing of RG involves repetitive steaming and drying, and 9-time-steamed RG (NSRG) is the most commonly consumed form. For a development of a convenient processing method, RG was
All members of R. glutinosa show the unique characteristic of intrinsic tolerance to paraquat (PQ). Antioxidant enzymes have been proposed to be the primary mechanism of PQ resistance in several plant species. Therefore, the antioxidant enzyme systems of R. glutinosa were evaluated by comparatively
Acteoside extracted from the leaves of Rehmannia glutinosa was examined to determine the mechanism(s) of its antioxidant properties. The deoxyribose assay system showed that acteoside has a high redox potential as electron donor, which generates hydroxyl radicals in an Fe3+-dependent manner similar
BACKGROUND
Diabetes, associated with hyperlipidemia and oxidative stress, would lead to an increased production of reactive oxygen species. Rehmannia glutinosa (Di Huang) is widely used to nourish yin, invigorate the kidney (shen), and treat xiao ke (a diabetes-like syndrome in Chinese medicine).
The objective of this study was to observe the effects of water extracts of Rehmannia glutinosa on the antioxidant system of Nrf-2 in diabetic mice induced by paraquat, and to provide the basis for its further development. Thirty male mice were randomly divided into the control group, model group
This study investigated the effects of Rehmannia glutinosa individually as well as in combination with the oral hypoglycemic agent, metformin in streptozotocin (STZ)-induced diabetic Wistar rats. R. glutinosa ethanolic extract was prepared and the constituents were characterized using fractionation
Quantitation analysis and chromatographic fingerprint of multi-components are frequently used to evaluate quality of herbal medicines but fail to reveal activity of the components. It is necessary to develop a rational approach of chromatography coupled with activity detection for Excessive activation of osteoclast activity is responsible for many bone diseases, such as osteoporosis, rheumatoid arthritis, periprosthetic osteolysis, and periodontitis. Natural compounds that inhibit osteoclast formation and/or function have therapeutic potential for treating these diseases.
