Abstract
Schisandra chinensis (SC), a plant of the Magnoliaceae family, commonly known as "North Schisandra chinensis", has been listed as a top-grade Chinese medicine in the Shennong Materia Medica Classic for its high medicinal value since ancient times. Polysaccharides from S. chinensis fruits (SCPs) are an active component in SC, which have various biological activity, including immune regulation, anti-tumor, antioxidant, liver protective, anti-inflammatory and hypoglycemic activity. Research has shown that the extraction methods of SCPs include hot water extraction, water extraction and alcohol precipitation, ultrasonic-assisted, microwave-assisted and so on. Different extraction methods can affect the yield and purity of polysaccharides, and to improve the extraction yield of SCPs, two or more extraction methods can be combined. SCPs are mainly composed of glucose, mannose, rhamnose, galactose, galacturonic acid and arabinose. This article aims to provide a systematic review of the research progress in the extraction and separation methods, structural characterization, and biological activity of SCPs both domestically and internationally in recent years. This deeply explores the pharmacological activity and action mechanism of SCPs, and provides a certain point of reference for the research and clinical application of SC.

[PMID: 37425492 PMCID: PMC10328733 DOI: 10.1155/2023/3269293] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 03/08/2023] [Accepted: 03/24/2023] [Indexed: 07/11/2023] Open
Abstract
Saengmaeksan (SMS) is a traditional drink that consists of three natural herbs, Lirio platyphlla, Panax ginseng, and Schisandra chinensis, and improves fatigue, liver function, and immunity. Moderate-intensity exercise has a positive effect on fatigue, liver function, and immune function, whereas long-term high-intensity training has a negative effect on these aspects. We hypothesized that SMS intake will improve fatigue (ammonia, lactic acid), liver function (aspartate transaminidase (AST) and alanine aminotransferase (ALT)), and immunity (IgA, IgG, IgM) with high-intensity training. To investigate this hypothesis, 17 male college tennis players were randomly assigned to SMS and placebo groups with high-intensity training. SMS and placebo were consumed in 110 mL doses for a total of 770 mL. High-intensity training was performed at 70%-90% of heart rate reserve, conducted five times weekly for 4 weeks. A significant interaction effect was observed between the SMS and control (CON) groups regarding ammonia, ALT, and IgA levels. Ammonia levels significantly decreased in the SMS group, but there was no difference in the lactic acid levels. AST significantly decreased in the SMS group. IgA significantly increased in the SMS group, IgM significantly decreased in both groups, but there was no change in IgG. The correlation analysis revealed positive correlation in ΔAST vs. ΔALT, ΔALT vs. ΔIgG, and ΔIgA vs. ΔIgG in the SMS group. These findings demonstrate that SMS intake can reduce ammonia, AST, ALT, and IgM levels, while causing an increase in IgA, which has a positive effect on fatigue reduction, liver function, and immunoglobulins in a high-intensity training or related environment.

Molecules 2021; 26:molecules26216554. [PMID: 34770962 PMCID: PMC8587461 DOI: 10.3390/molecules26216554] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2021] [Revised: 10/25/2021] [Accepted: 10/27/2021] [Indexed: 11/28/2022] Open
Abstract
To scientifically clarify the hepatoprotective constituents of Fructus Schizandrae chinensis, eleven batches samples of total dibenzocyclooctadiene lignans (TDL) from Schisandra chinensis were prepared by using the optimum extraction technique. Characteristic high-performance liquid chromatography (HPLC) chromatograms were obtained through HPLC analysis technology, and the hepatoprotective effects of the eleven batches of TDL were evaluated by MTT assay. Based on the chemical and biological activity results, the spectrum-effect relationship between the characteristic HPLC fingerprints and the hepatoprotective effect of TDL was established using Minitab 16.0 data analysis software. On the basis of the spectrum-effect relationship, thirteen compounds (1–13) were obtained from the TDL by chemical natural product chemical separation and purification technology, and their structures were identified on the basis of the spectral data and the literature. Based on these compounds, thirteen common peaks among the thirty-three chromatographic peaks in the above HPLC fingerprints were identified. Our findings showed that some components, including, schisandrin B (2), schisandrin A (3), and schisandrol B (7) had significant roles in promoting hepatoprotective activity. Preliminary verification of the spectrum-effect relationship of TDL from S. chinensis was carried out, and the results confirmed that the activity of a composite of these three key components in optimal ratios was better than that of any individual compound, which potentially confirmed the reliability of the spectrum-effect relationship and the synergistic effects of traditional Chinese medicine.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Schisandra chinensis (Turcz.) Baill. (S. chinensis), locally known as "Wuweizi", has been used in the treatment of chronic cough as prescription medications of Traditional Chinese Medicine for thousands of years. However, the components of antitussive activity of S. chinensis and the mechanism are poorly understood. AIM OF THE STUDY This study aims to investigate the antitussive activity of polysaccharides extracted from S. chinensis. MATERIALS AND METHODS S. chinensis fruit polysaccharide-1 (SCFP-1) was extracted by 95% ethanol and distilled water successively, and then the water extraction was isolated with chromatographic columns. The preliminary characterization of SCFP-1 was analyzed by gel permeation chromatography (GPC), gas chromatography-mass spectrometry (GC-MS) and some other recognized chemical methods. Antitussive potential of SCFP-1 was estimated at dose of 250, 500, and 1000mg/kg respectively by peroral administration in a guinea pigs model with cough hypersensitivity induced by cigarette smoke (Chronic cough model) or acute cough guinea model induced by citric acid (Acute cough model). Also, the time-dependent antitussive effect of SCFP-1 were evaluated with acute cough model, and compared with codeine. RESULTS The molecular of SCFP-1 was 3.18×104Da, mainly being composed of glucose and arabinose (66.5% and 29.4%, respectively). Peroral administration of SCFP-1 at 250, 500, and 1000mg/kg showed remarkable suppressive effects respectively on cough in both of chronic cough model and acute cough model. Meanwhile, inflammatory cell in BALF and some typical characteristics of nonspecific airway inflammation in animals exposed to CS was significantly attenuated after pretreatment with SCFP-1. The cough suppression of SCFP-1 (500 mg/kg) stablly lasted during the whole 5 h of time-dependent experiment, while no positive effect was observed after 300 min of oral administration of codeine. CONCLUSIONS SCFP-1 is one of the antitussive components of S. chinensis.

Abstract
A number of drugs and herbal compounds have been documented to cause hepatoxicity. Schisandrin B (Sch B) is an active dibenzocyclooctadiene isolated from Schisandrae fructus, with a wide array of pharmacological activities. However, the potential hepatotoxicity of Sch B is a major safety concern, and the underlying mechanism for Sch B-induced liver toxic effects is not fully elucidated. In the present study, we aimed to investigate the liver toxic effects and the molecular mechanisms of Sch B in mouse liver and macrophage cells. The results have shown that Sch B exhibits potent grow inhibitory, proapoptotic, and proautophagic effects in AML-12 and RAW 264.7 cells. Sch B markedly arrested cells in G1 phase in both cell lines, accompanied by the down-regulation of cyclin dependent kinase 2 (CDK2) and cyclin D1 and up-regulation of p27 Kip1 and checkpoint kinase 1. Furthermore, Sch B markedly increased the apoptosis of AML-12 and RAW 264.7 cells with a decrease in the expression of B-cell lymphoma-extra-large and (Bcl-xl) B-cell lymphoma 2 (Bcl-2), but an increase in the expression of B-cell lymphoma 2-associated X protein (Bax). Sch B promoted the cleavage of caspase 3 and poly-adenosine diphosphate-ribose polymerase (PARP) in both cell lines. Additionally, Sch B significantly induced autophagy of AML-12 and RAW 264.7 cells. Sch B inhibited the activation of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway, as indicated by their altered phosphorylation, contributing to the proautophagic effect of Sch B. Taken together, our findings show that the inducing effects of Sch B on cell cycle arrest, apoptosis, and autophagy may contribute to its liver toxic effects, which might provide a clue for the investigation of the molecular toxic targets and underlying mechanisms for Sch B-induced hepatotoxicity in herbal consumers. More studies are warranted to fully delineate the underlying mechanisms, efficacy, and safety of Sch B for clinical use.

Abstract
Background Schisandrin B (Sch B), a dibenzocyclooctadiene compound, is isolated from schisandrae fructus (SF). This study was conducted to compare the time- and dose-response between Sch B- and SF oil (SFO)-induced changes in hepatic and serum parameters in mice. Methods Institute of Cancer Research (ICR) mice were given a single oral dose of Sch B (0.125–2 g/kg) or SFO (0.3–5 g/kg). Serum alanine aminotransferase (ALT) activity, hepatic malondialdehyde, and triglyceride (TG) levels were measured at increasing time intervals within 6–120 hours postdosing. Results Serum ALT activity was elevated by 60%, with maximum effect (Emax) =45.77 U/L and affinity (KD) =1.25 g/kg at 48–96 hours following Sch B, but not SFO, treatment. Sch B and SFO treatments increased hepatic malondialdehyde level by 70% (Emax =2.30 nmol/mg protein and KD =0.41 g/kg) and 22% (Emax =1.42 nmol/mg protein and KD =2.56 g/kg) at 72 hours postdosing, respectively. Hepatic index was increased by 16%–60% (Emax =11.01, KD =0.68 g/kg) and 8%–32% (Emax =9.88, KD =4.47 g/kg) at 12–120 hours and 24–120 hours after the administration of Sch B and SFO, respectively. Hepatic TG level was increased by 40%–158% and 35%–85%, respectively, at 12–96 hours and 6–48 hours after Sch B and SFO treatment, respectively. The values of Emax and KD for Sch B/SFO-induced increase in hepatic TG were estimated to be 22.94/15.02 μmol/g and 0.78/3.03 g/kg, respectively. Both Sch B and SFO increased serum TG (up to 427% and 123%, respectively), with the values of Emax =5.50/4.60 mmol/L and KD =0.43/2.84 g/kg, respectively. Conclusion The findings indicated that Sch B/SFO-induced increases in serum/hepatic parameters occurred in a time-dependent manner, with the time of onset being serum TG level < hepatic TG level < hepatic index < serum ALT activity. However, the time of recovery of these parameters to normal values varied as follow: serum TG level < hepatic TG level and liver injury < hepatic index. The Emax and affinity of Sch B on tissue/enzyme/receptor were larger than those of SFO.
