Fingerprinting analysis of fresh ginseng roots of different ages using1H-NMR spectroscopy and principal components analysis

Fingerprinting analysis of fresh ginseng according to root age was performed using 1H-NMR spectroscopy and multivariate analysis techniques. Various peaks were detected in the aliphatic (0-3 ppm), sugar (3-6 ppm), and aromatic (6-9 ppm) regions of the 1H-NMR spectra of the water extracts of fresh ginseng root. The use of principal components (PCs) analysis (PCA) for metabolomic profiling allowed the large 1H-NMR data set obtained for various metabolites to be reduced to PC1, PC2, and PC3. Two dimensional score plots showed clear separations with these three components at different roots ages, and explained 89.6% of the total variance. Canonical discriminant analysis identified the ginseng roots at various ages from the NMR results with over 89.9% discrimination accuracy. These results indicate that the combination of 1H-NMR and PCA provides a very promising tool for the authentication and quality control of fresh ginseng roots at different ages.     

参麦注射液对百草枯所致肺损伤的保护作用

目的探讨参麦注射液在百草枯中毒所致肺损伤中的作用。方法120只SD大鼠随机分为百草枯中毒组（APP）,参麦注射液治疗组（SM1,SM2,SM3）。HE染色观察参麦注射液治疗组组织结构变化,采用免疫组织化学法测定各组肺组织中TGF—β1、IL-1β的表达水平。结果百草枯中毒组肺组织充血水肿明显,肺泡破坏严重,治疗组有所减轻;各治疗组与百草枯中毒组之间转化生长因子β-1（TGF—β1）,白细胞介素-1β（IL—1β）水平均较治疗组明显降低,各治疗组随剂量的增加,TGF-β1,IL-1β水平有明显下降,差异有显著性（P〈0．05）。结论参麦注射液在百草枯所致中毒大鼠肺损伤中能使TGF—β1,IL-1β表达水平下调,减轻肺泡炎症和充血程度,减轻百草枯中毒所致肺损伤,延缓和抑制肺纤维化的发生、发展。

Clinical potentials of ginseng polysaccharide for treating gestational diabetes mellitus

Gestational diabetes mellitus (GDM) is the most common glucose metabolism complication or cause of potential impaired glucose tolerance that can occur either before or during pregnancy and lactation. The prevalence of GDM and its related complications in young women is increasing, and this condition may cause serious outcomes and health hazards to the foetus. However, traditional oral hypoglycaemic drugs have potential safety hazards; therefore, it is urgent to develop new, safe, effective, and easily administered agents and remedies. Ginseng polysaccharide (GPS), which is isolated from Panax (P.) ginseng C. A. Meyer, exhibits notably promising biological activities and effects; specifically, it has been shown to lower blood glucose with mild, safe, and nontoxic characteristics, and it can also improve human bodily functions. Hence, we hypothesise that GPS might be used as an additional therapy and candidate agent for treating GDM. This review innovatively summarizes the available reports and evidence from basic studies to analyze the potential for and feasibility of using GPS as a new therapeutic agent for treating GDM. Additionally, for the first time, this review provides a rationale for the use of GPS. Our summarized results show that GPS may be developed as a novel antidiabetic drug and a remedy for use in preventing and treating GDM, with great application prospects.

20-O-β-d-glucopyranosyl-20(S)-protopanaxadiol-fortified ginseng extract attenuates the development of atopic dermatitis-like symptoms in NC/Nga mice

Ethnopharmacological relevance

Ginseng and ginsenosides are frequently used in the treatment of chronic inflammatory diseases. Recently, 20-O-β-d-glucopyranosyl-20(S)-protopanaxadiol (GPD), the main metabolite of ginsenosides, was reported to have both anti-allergic and anti-pruritic effects. The immunomodulatory effects of GPD-fortified ginseng extract (GFGE) on atopic dermatitis (AD)-like symptoms in mice were investigated. This study was designed to investigate the preventive effect of GFGE on AD-like symptoms.

Materials and methods

The effects of orally administered GFGE on Dermatophagoides farinae body extract (DFE)-induced AD-like symptoms in NC/Nga mice were assessed by analyzing dermatitis score, ear thickness, scratching time, skin histological changes, and serum level of macrophage-derived chemokine (MDC). In addition, splenocytes were isolated from the mice and stimulated with anti-CD3 and anti-CD28 monoclonal antibodies to produce cytokines.

Results

Oral administration of GFGE significantly attenuated DFE-induced increases in dermatitis score, ear thickness, scratching time, and severity of skin lesions in NC/Nga mice. GFGE treatment also reduced level of MDC in serum, infiltration of eosinophils and mast cells in skin, and production of cytokines in splenocytes.

Conclusions

These results suggest that GFGE might ameliorate DFE-induced AD-like symptoms and be an alternative therapeutic agent for the prevention of AD.
