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 were determined on the basis of IR, UV, HRESIMS, and NMR spectroscopic analyses. The antioxidant and cytotoxic effects of isolated compounds were evaluated in vitro. The isolated compounds (IC50 > 200 μM) did not display 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity...

BACKGROUND: Saikosaponin d (SSd) is one of the main active triterpene saponins in Bupleurum falcatum. It has a steroid-like structure, and is reported to have pharmacological activities, including liver protection in rat, cell cycle arrest and apoptosis induction in several cancer cell lines. However, the biological functions and molecular mechanisms of mammalian cells under SSd treatment are still unclear. METHODS: The cytotoxicity and apoptosis of hepatic stellate cells (HSCs) upon SSd treatment were discovered by MTT assay, colony formation assay and flow cytometry...

Bupleurum falcatum, which belongs to the family Apiaceae, has long been applied for curative treatments, especially as a liver tonic, in herbal medicine. The chloroplast (cp) genome has been an ideal model to perform the evolutionary and comparative studies because of its highly conserved features and simple structure. The Apiaceae family is taxonomically close to the Araliaceae family and there have been numerous complete chloroplast genome sequences reported in the Araliaceae family, while little is known about the Apiaceae family...

Recent studies demonstrated that treatment with saikosaponin A (SSA) - an active ingredient of the medicinal herb, Bupleurum falcatum L. - selectively suppressed, likely via a GABAB receptor-mediated mechanism, intravenous self-administration of morphine and cocaine in rats [Yoon et al., 2012; 2013]. The present study was designed to investigate whether the capacity of SSA to suppress morphine and cocaine self-administration extends to oral alcohol self-administration. To this end, selectively bred Sardinian alcohol-preferring (sP) rats were trained to lever-respond on a Fixed Ratio (FR) 4 (FR4) schedule of reinforcement for alcohol (15%, v/v) in daily 30-min sessions...

A rapid and sensitive ultra fast liquid chromatography tandem mass spectrometry method (UFLC-MS/MS) was developed and validated for the simultaneous determination of six Saikosaponins (SSs) (SSa, SSb1, SSb2, SSd, SSc, SSf) of Bupleurum Dropping Pills (BDP) in rat plasma using chloramphenicol as the internal standard (IS). The SSs were separated using an ACQUITY UPLC(®) BEH C18 column (50 mm × 2.1mm, 1.7 μm) and detection of these compounds were done by using a Qtrap 5500 mass spectrometer coupled with negative electrospray ionization (ESI) source under the multiple reaction monitoring (MRM) mode...

Neuronal oxidative stress (OS) injury has been proven to be associated with many neurodegenerative diseases, and thus, antioxidation treatment is an effective method for treating these diseases. Saikosaponin-D (SSD) is a sapogenin extracted from Bupleurum falcatum and has been shown to have many pharmacological activities. The main purpose of this study was to investigate whether and how SSD protects PC12 cells from H2O2-induced apoptosis. The non-toxic level of SSD significantly mitigated the H2O2-induced decrease in cell viability, reduced the apoptosis rate, improved the nuclear morphology, and reduced caspase-3 activation and poly ADP-ribose polymerase (PARP) cleavage...

The immunoregulatory protective properties of (+)-3'α-angeloxy-4'-keto-3',4'-dihydroseselin (Pd-Ib) isolated from Bupleurum malconense has not been reported. In the present study, the therapeutic effect of Pd-Ib (30, 60, and 120 mg/kg/day) was examined in a mouse model of dextran sulfate sodium (DSS)-induced acute colitis. Administration of Pd-Ib significantly reduced the disease activity index, inhibited the shortening of colon length, reduced colonic tissue damage, and suppressed colonic myeloperoxidase activity and nitric oxide levels in mice with DSS-induced colitis...

ETHNOPHARMACOLOGICAL RELEVANCE: Bupleurum chinense is a traditional Chinese medicinal herb which has been used to treat various inflammatory and infectious diseases, while Bupleurum kaoi is an endemic plant in Taiwan. We determined whether B. chinense and B. kaoi and their biologically active saikosaponin compounds possess anti-melanoma activity. In addition, we developed a novel saikosaponin-d nanoparticle system to improve its solubility, and evaluated its antiproliferative effects and molecular mechanisms in melanoma cells...

Alzheimer's disease (AD) is a chronic neurodegenerative disease and the risk of developing it increases with advancing age. In this study, we investigated the protective effects of saikosaponin C (SSc), one of the main bioactive components produced by the traditional Chinese herb, radix bupleuri, the root of Bupleurum falcatum, against AD in various neuronal models. Interestingly, we found that SSc has dual effects on AD by targeting amyloid beta (Aβ) and tau, two key proteins in AD. SSc significantly suppressed the release of both Aβ peptides 1-40 and 1-42 into cell culture supernatants, though it does not affect BACE1 activity and expression...

Drug-induced liver injury can lead to acute liver failure. Saikosaponin D (SSD) is a major component isolated from the medicinal herb Bupleurum falcatum, which has been linked to hepatotoxicity. We previously reported that SSD disrupted PDGF-βR pathway leading to mitochondrial apoptosis in human LO2 hepatocytes. The present study was aimed at further exploring the underlying mechanisms in vitro and in vivo. We initially determined the concentration range of SSD at up to 2μM for subsequent apoptosis examinations...

Saikosaponin-d is one of the main bioactive components in the traditional Chinese medicine Bupleurum falcatum L and possesses anti-inflammatory and immune-modulatory properties. The current study aimed to investigate the protective effects of saikosaponin-d on ventilator-induced lung injury (VILI) in rats. We found that saikosaponin-d treatment significantly attenuated the pathological changes of lungs induced by mechanical ventilation. Administration of saikosaponin-d reduced the pulmonary neutrophil infiltration as well as the MPO concentrations...
