Heat stress stimulates the production of reactive oxygen species (ROS), which cause oxidative damage in the kidney. This study clarifies the mechanism by which saikosaponin-d (SSd), which is extracted from the roots of Bupleurum falcatum L, protects heat-stressed pig kidney proximal tubular

In the search for biologically active compounds from the roots of Bupleurum chinense D C., phytochemical investigation of its ethanol extract led to the isolation and identification of a new 8-O-4' neolignan glucoside, saikolignanoside A (1), along with eight known lignans (2-9). Their structures

Bupleuri Radix (BR), the dried roots of Bupleurum falcatum L., has been used in folk medicine as an antiinflammatory and antioxidative agent. The aqueous extract of BR was evaluated for its possible ameliorative effect in the regulation of hyperthyroidism in l-thyroxine- (LT4-) induced rat model.

Danzhixiaoyao Wan (DW) is a common 10 herbs formulation in China for regulating several clinical conditions affecting women. This research tried to explain one of DW's functions, purging heat, using in vitro pharmacological analyses. The whole formulation and each single herb of DW were compared

The roots of Bupleurus spp. have been used in traditional Chinese herbal medicine for curing liver diseases. Although bioactive saikosaponins have been detected in the leaves as well as in the roots, the aerial parts of the plants are discarded as waste. In the present study, a leaf infusion of B.

Fractionation with supercritical CO(2) is employed to divide ethanolic extract (E) of B. kaoi into four fractions (R, F1, F2 and F3). To assess the selectivity of the fractionation, extracts of the four fractions were characterized in terms of the hepatoprotective capacity and activity of

Oxidative stress is a condition that might predispose the individuals to diseases including cancer. The 8-hydroxydeoxyguanosine (8-OHdG) is a marker that reflects oxidative DNA damage in the body. In this study, seven Saudi medicinal plants were investigated for their potential against oxidative DNA

Chinese medicine plays a pivotal role in hepatoprotective treatment. In the present study, a water-soluble polysaccharide fraction (WBCP) was fractioned from the roots of Bupleurum chinense and purified by DEAE-cellulose and Surperdex 200 HR chromatography. The physicochemical properties,

OBJECTIVE The purpose of this study was to evaluate the anticancer, apoptotic and antioxidant properties of Bupleurum chinense (B.C) root extract against human epithelial ovarian cancer cells (HO-8910) in vitro. METHODS MTT assay was used to evaluate the cell viability of HO-8910 cells after

The essential oil from the roots of Bupleurum longiradiatum, obtained by hydro-distillation was analyzed by gas chromatography/mass spectrometry (GC/MS) and evaluated for antimicrobial activity and antioxidant activity. Fifty-one compounds were identified, representing 99.3% of the total oil. The

Bupleuri Radix (Bupleurum spp. root) is one of the most important crude drugs in Korea, China and Japan. We investigated the total phenolic content and antioxidant activity of three Bupleurum taxa (B. falcatum, B. falcatum 'Mishima' and B. latissimum). The highest total phenolic content was found in

Saikosaponin a (SSa), one of the major active components of Bupleurum falcatum, has antioxidant and anti-inflammatory pharmacological properties. However, the effects of SSa on liver injury have not been reported. In the present study, we evaluated the protective effects and mechanisms of SSa on

OBJECTIVE to investigate the effect of isochaihulactone (also known as K8), a lignan compound of Bupleurum scorzonerifolium, on H(2)O(2)-induced cytotoxicity in neuronally differentiated PC12 cells (nPC12). METHODS viability of neuronal PC12 cells was measured using MTT assay. Protein expression was

This study presents the effects of the Achillea phrygia Boiss. et Bal. and Bupleurum croceum Fenzl. extracts obtained by different solvents (ethyl acetate, methanol and water) on selected enzyme inhibitory effects and antioxidant ability with screening bioactive compounds. Total and individual

Traditional Chinese Medicine (TCM), a complex natural herbal medicine system, has increasingly attracted attention from all over the world. Most research has illustrated the mechanism of TCM based on the active components or single herbs. It was fruitful and effective but far from satisfactory as it
