Therapeutic effect of notoginseng saponins before and after fermentation on blood deficiency rats

Notoginseng saponins (NS) are the active ingredients in Panax notoginseng (Burk.) F.H. Chen (PN). NS can be transformed depending on how the extract is processed. Fermentation has been shown to produce secondary ginsenosides with increased bioavailability. However, the therapeutic effect of fermented NS (FNS) requires further study. The present study compared the compositions and activities of FNS and NS in blood deficiency rats, which resembles the symptoms of anemia in modern medicine, induced by acetylphenylhydrazine and cyclophosphamide. A total of 32 rats were randomly divided into control, model, FNS and NS groups. A blood deficiency model was established and then treatment was orally administered for 21 days. The results of component analysis indicated that some saponins transformed during the fermentation process resulting in a decrease of notoginsenoside R1, and ginsenosides Rg1, Rb1 and Re, and an increase in ginsenosides Rd, Rh2, compound K, protopanaxadiol and protopanaxatriol. The animal results showed that both FNS and NS increased the number of white blood cells (WBCs), red blood cells, hemoglobin, platelets and reticulocytes, and the levels of granulocyte-macrophage colony-stimulating factor (GM-CSF), erythropoietin (EPO) and thrombopoietin (TPO), decreased the G0/G1 phase and increased G2/M phase, and decreased the apoptosis rate of bone marrow (BM) cells, which suggested a contribution to the recovery of hematopoietic function of the BM cells. FNS and NS increased the protein expression levels of the cytokines IL-4, IL-10, IL-12, IL-13, TGF-β, IL-6, IFN-γ and TNF-α, and the mRNA expression levels of transcription factors GATA binding protein 3 and T-box expressed in T cell (T-bet). FNS and NS treatment also increased the number of CD4+ T cells, and decreased the enlargement of the rat spleen and thymus atrophy, which indicated a protective effect on the organs of the immune system. The results of the present study demonstrated that compared with NS, FNS showed an improved ability to increase the levels of WBCs, lymphocytes, GM-CSF, EPO, TPO, aspartate aminotransferase, IL-10, IL-12, IL-13 and TNF-α, and the mRNA expression levels of T-bet, and decrease alanine aminotransferase levels. The differences seen for FNS treatment could arise from their improved bioavailability compared with NS, due to the larger proportion of hydrophobic ginsenosides produced during fermentation.

Metabonomics Study of the Hematopoietic Effect of Medicinal Wine Maoji Jiu on a Blood Deficiency Rat Model by Ultra-High-Performance Liquid Chromatography Coupled to Quadrupole Time-of-Flight Mass Spectrometry and a Pattern Recognition Approach

Maoji Jiu (MJ) is a kind of medicinal wine that has been widely used by Chinese people for many years to nourish and promote blood circulation. The purpose of this study was to investigate the hematopoietic effect of MJ on the metabolism of blood deficient rats and to explore the underlying hematopoietic regulation mechanisms. Blood deficiency model rats were induced by subcutaneous injection of N-acetylphenylhydrazine (APH) and intraperitoneal injection of cyclophosphamide (CTX). The plasma metabolic fingerprints of blood deficiency model rats with and without MJ treatment were obtained by using metabonomics based on ultra-high-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (UHPLC-QTOF/MS). Orthogonal partial least squares-discriminant analysis (OPLS-DA) was used to evaluate the hematopoietic effect of MJ and identify potential biomarkers in the plasma of blood deficiency model rats. The levels of white blood cells (WBC), red blood cells (RBC) and hemoglobin (HGB) and the activity of antioxidant capacity showed a recovery trend to the control group after MJ treatment, while the dose of 10 mL/kg showed the best effect. In this study, thirteen potential biomarkers were identified, which were mainly related to seven metabolic pathways, including linoleic acid metabolism, d-glutamine and d-glutamate metabolism, alanine, aspartate and glutamate metabolism, tryptophan metabolism, pyrimidine metabolism, porphyrin and chlorophyll metabolism and arginine biosynthesis. Metabolomics was applied frequently to reflect the physiological and metabolic state of organisms comprehensively, indicating that the rapid plasma metabonomics may be a potentially powerful tool to reveal the efficacy and enriching blood mechanism of MJ.

A Review of Edible Jujube, the Ziziphus jujuba Fruit: A Heath Food Supplement for Anemia Prevalence

The fruits of Ziziphus jujuba, commonly known as jujube, red date or Chinese date, are taken as fresh or dried food, and as traditional medicine worldwide due to high nutritional and health values. Traditionally in China, jujube is considered as a medicinal fruit that is being used in treating blood deficiency. In this review, the beneficial effects of jujubes on the hematopoietic functions are summarized and discussed. As illustrated in cell and animal models, the application of jujube extract possessed beneficial effects, including regulation of erythropoiesis via activation of hypoxia inducible factor-induced erythropoietin, potential capacity in recycling heme iron during erythrophagocytosis and bi-directional regulation of immune response. Thus, the blood-nourishing function of jujube is being proposed here. Flavonoid, polysaccharide and triterpenoid within jujube could serve as the potential active ingredients accounting for the aforementioned health benefits. Taken together, these findings provide several lines of evidence for further development of jujube as supplementary products for prevention and/or treatment of anemia.

[Spectrum-effect relationships on enriching blood activities of fresh and dry roots of Angelica sinensis]

Ultra performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(LC-MS) was used to establish the chromatography fingerprint for fresh(FRAS) and dry(RAS) roots of Angelica sinensis from 10 different places. The rat model of blood deficiency was established by acetyl-phenyl-hydrazine(APH) and cyclophosphamide(CTX). Then grey relational analysis(GRA) and partial least squares regression(PLS) were used to investigate the spectrum-effect relationship between the relative contents and the data of enriching blood pharmacodynamics efficacy. The results showed that the FRAS and RAS had certain enriching blood activities(P<0.05). The contribution degree of the FRAS and RAS to enriching blood activities of each common peaks were determined by regression coefficient. Among them, 4 common peaks contributed significantly to the effect of enriching blood activities, P1(unknown), P2(unknown), P7(ferulic acid), and P11(senkyunolide A) respectively. This paper investigated the spectrum-effect relationship between enriching blood activities and LC-MS chromatography fingerprint of RAS and FRAS, and determined the effective compositions of RAS and FRAS with enriching blood activities. It lays a theoretical foundation for the comprehensive development and utilization of A. sinensis.

[Study on blood enrichment mechanism of steamed notoginseng based on metabolomics method]

In this paper,ultra performance liquid chromatography coupled with time-of-flight mass spectrometry( UPLC-Q-TOFMS) technique was used to study the effects of steamed notoginseng on endogenous markers in plasma of rats with hemolytic anemia induced by N-acetyl phenyl hydrazine( APH). The aim was to find out the potential biomarkers and possible blood enriching mechanism of steamed notoginseng on hemolytic anemia rats. In the experiment,steamed notoginseng medicine pair( steamed notoginseng-ginseng)and compound medicines( Sanqi Yangxue Capsules) were used respectively to intervene in APH-induced hemolytic anemia model rats.Then blood routine indexes such as red blood cells( RBC),hemoglobin( Hb) and related organ indexes were determined. As compared with the blank group,the RBC and Hb levels in the model group were substantially decreased( P< 0. 01),while the liver and spleen organ indexes were increased( P< 0. 05). The results of blood routine and organ index demonstrated that the blood deficiency model was successfully established. Steamed notoginseng can significantly increase the RBC level of rats( P<0. 01),and the related indicators of each drug group had a trend of returning to normal levels,verifying the blood enriching effect of steamed notoginseng. The UPLC-Q-TOF-MS technique,principal component analysis( PCA) and partial least squares-discrimination analysis( PLS-DA) were used to analyze the metabolic profiles between the normal group and the model group. Twenty-six potential biomarkers for hemolytic anemia were screened in plasma. Nine metabolites such as retinol,L-valine,and arachidonic acid were down-regulated in the blood deficiency rats,and 17 metabolites such as protoporphyrin Ⅸ and niacinamide were up-regulated. The metabolic level of biomarkers could be changed to a normal state after rats were given with steamed notoginseng,drug pairs,and compound prescriptions. It can be speculated that steamed notoginseng may play a role of blood tonifying by improving biosynthesis of valine,leucine and isoleucine,as well as metabolic pathways such as retinol metabolism and arachidonic acid metabolism.
