Lipopolysaccharides (LPS) contamination in herbal crude polysaccharides is inevitable. The present study was performed to explore the effect of polymyxin B on abolishing the influence of LPS contamination in mononuclear cells. LPS was pretreated with polymyxin B sulfate (PB) at different concentrations for 1, 5 or 24 h, and then used to stimulate RAW264.7 and mouse peritoneal macrophages (MPMs). The nitric oxide (NO) and tumor necrosis factor-α (TNF-α) in cell culture supernatant, as the indications of cell response, were assayed...

BACKGROUND: Bupleurum chinense, a well-known Traditional Chinese Medicine, has been used for thousands of years in China. In this study, we would suggest that BPS could improve the prognosis of sepsis through its impact on redistribution of BMCs, which triggers immune reversal in late sepsis. METHODS: BALB/c mice were divided into five groups: sham burn group, burn plus P. aeruginosa group, burn plus P. aeruginosa with BPS (40 mg/kg, 100 mg/kg and 250 mg/kg) treatment group, and they were sacrificed at postburn day (PBD) 0, 3, 5 and 7...

5-Hydroxytryptamine 2C (5-HT2C) receptor is one of the major targets of anti-obesity agents, due to its role in regulation of appetite. In the present study, the 70% EtOH extract of the roots of Bupleurum chinense was revealed to have agonistic activity on 5-HT2C receptor, and the subsequent bioassay-guided isolation led to identification of several saikosaponins as the active constituents with 5-HT2C receptor agonistic activity in vitro and anti-obesity activity in vivo. The new compound, 22-oxosaikosaponin d (1), was determined by extensive spectroscopic analyses (HR-ESI-MS, IR, and 1D and 2D NMR)...

Saikosaponin D (SSd) is a type of Saponin derivative, which is a component extracted from Bupleurum falactum. SSd has been reported to exert anticancer activities. However, the effects of SSd on gliomas have not been elucidated. The aim of the present study was to investigate the pharmacological functions and potential molecular mechanisms of SSd in human U87 glioblastoma cells. The cells were treated with SSd at various concentrations for 48 h, the cell viability was assessed with 3‑(4,5‑dimethylthiazol‑2‑yl)‑2,5‑diphenyltetrazolium assay, and the activation of Akt, extracellular signal‑regulated kinases (ERK), c‑Jun N‑terminal kinases (JNK) and caspase‑3 was assessed by western blotting...

BACKGROUND: Bupleuri Radix (Chaihu) represents one of the most successful and widely used herbal medicines in Asia for the treatment of many diseases such as inflammatory disorders and infectious diseases over the past 2000 years. In the Chinese Pharmacopoeia, Chaihu is recorded as the dried roots of Bupleurum chinense DC. and B. scorzonerifolium Willd. (Umbelliferae). However, the widespread demand for the herb has tended to far outstrip the supply. Whether the aerial parts, which account for 70 ~ 85% of the dry weights of Bupleurum species, could be used as an alternative for the root has become an important scientific issue for the sustainable utilization of Bupleurum species...

Multidrug resistance (MDR) cells over expressing P-glycoprotein (P-gp) encoded by the MDR1 gene is major obstacles for successful cancer chemotherapy. P-gp could extrude anti-cancer drugs out of cancer cells and decrease effective intracellular drug concentrations. MDR reversal agents for P-gp can restore the sensitivity of MDR cells to such drugs. Saikosaponin D (SSd), one of the major triterpenoid saponins derived from Bupleurum chinense DC (BCDC), has been shown to possess anti-inflammatory, anti-infectious and anti-tumor properties...

Bupleurum chinense belongs to the Bupleurum spp. family that has been used in traditional herbal medicine for over thousand years. It has been reported to have anti-inflammatory, anti-oxidant, hepato-protective, antipyretic, analgesic, anti-fibrotic and immunomodulatory effect. However, the effect of B. Chinense on allergic asthma remains unclear. This study investigated the immunomodulatory effects of B. Chinense extracts (BCE) on airway inflammation in asthmatic mice model. In the ovalbumin (OVA)-induced allergic asthma model, we evaluated the number of total cells, differential inflammatory cells and the production of proinflammatory cytokines in bronchoalveolar lavage fluid (BALF) and lung homogenate as well as histological structure...

Chemical investigation of the leaves of Bupleurum lancifolium led to the isolation and identification of two triterpenoid saponins previously undescribed named 3-O-[α-L-rhamnopyranosyl (1 → 4)-β-D-glucopyranosyl] echinocystic acid 28-O-β-D-glucopyranosyl ester (1) and 3-O-[α-L-rhamnopyranosyl (1 → 4)-β-D-glucopyranosyl] oleanolic acid 28-O-β-D-glucopyranosyl ester (2) along with the two known compounds isorhamnetin 3-rutinoside (3) and rutin (4). Their structures were elucidated by different spectroscopic methods, including HRESIMS analysis as well as 1D and 2D NMR experiments...

The objective of the present study was to search for medicinal-herb combinations based on Radix Bupleurum chinense DC ("B"), Rhizoma Corydalis yanhusuo WT Wang ("Y"), Caulis Polygonum multiflorum Thunb ("P"), and Flos Albizia julibrissin Durazz ("A") for antiaging, anxiolytic, and sedative effects. Application of the D-galactose induced accelerated-aging model employing male ICR mice showed that oral administration of some combinations of B, Y, P, and A significantly improved spatial memory in Y-maze test and reduced brain levels of tumor necrosis factor-α and interleukin-6 based on immunoassays and oxidative stress marker malondialdehyde, based on the thiobarbituric acid test, and the loss of whiskers, indicating antiaging and antineurodegeneration effects...

This study to investigate antiviral components from the roots of Bupleurum marginatum var. stenophyllum led to the isolation of five novel saikosaponins, namely 6″-O-crotonyl-saikosaponin a (1), tibesaikosaponin I (2), tibesaikosaponin II (3), tibesaikosaponin III (4), tibesaikosaponin IV (5), along with 9 known analogues (6-14). Their structures were established by spectral data analyses (IR, MS, 1D and 2D NMR) and by comparison of spectral data with those of the related known compounds. Antiviral testing of all compounds against influenza A virus A/WSN/33 (H1N1) in 293TGluc cells showed that nepasaikosaponin k (12), saikosaponin n (13) and saikosaponin h (14) behaved more potent inhibitory activity and selectivity than the positive control, Ribavirin...

The disturbed dopamine availability and brain-derived neurotrophic factor (BDNF) expression are due in part to be associated with attention deficit hyperactivity disorder (ADHD). In this study, we investigated the therapeutical effect of saikosaponin a (SSa) isolated from Bupleurum Chinese DC, against spontaneously hypertensive rat (SHR) model of ADHD. Methylphenidate and SSa were orally administered for 3 weeks. Activity was assessed by open-field test and Morris water maze test. Dopamine (DA) and BDNF were determined in specific brain regions...

Recent lines of experimental evidence have indicated that saikosaponin A (SSA) - a bioactive ingredient of the medicinal plant, Bupleurum falcatum L. - suppressed alcohol, morphine, and cocaine self-administration in rats. The present paper was designed to assess whether the protective properties of SSA on addiction-related behaviors generalize to a hyperpalatable food such as a chocolate-flavored beverage (CFB). To this end, rats were initially trained to lever-respond for CFB [5% (w/v) Nesquik(®) powder in water] under fixed ratio (FR) 10 (FR10) schedule of reinforcement...

Bupleurum chinense is a well-known traditional Chinese medicine. Polysaccharides extracted from medical plants possess multiple healthy benefits. In the present study, an alkali-extracted polysaccharide (BCAP-1) was isolated from Bupleurum chinense, and evaluated its physicochemical features, anti-tumor activities and immunomodulatory effects. BCAP-1 was obtained by alkali-extraction, ethanol precipitation, and fractionation by DEAE-cellulose and Sepharose CL-6B columns. BCAP-1 markedly inhibited Sarcoma 180tumor growth in tumor-bearing mice, and increased the secretion of TNF-α in serum...
