ABSTRACT

Paeoniae Radix Alba is the dried root of Paeonia lactiflora, which was first recorded in the Shennong's Classic of Materia Medica and listed as the top grade. It is a common blood-tonifying herb, and its chemical components are mainly monoterpenes and their glycosides, triterpenes, flavonoids and so on. Modern research has demonstrated that Paeoniae Radix Alba has the activities of anti-inflammation, pain easing, liver protection, and anti-oxidation, and thus it is widely used in clinical practice and has broad development prospects. In this paper, the research progress on the chemical composition, pharmacological effects, and quality control of Paeoniae Radix Alba were summarized. On this basis, the Q-markers of Paeoniae Radix Alba were predicted from the aspects of mass transfer and traceability, chemical composition specificity, and availability and measurability of chemical components, which will provide a scientific basis for the quality evaluation of Paeoniae Radix Alba.

ABSTRACT

The present study evaluates different processing and drying methods and investigates their effects on the chemical components in Paeoniae Radix Alba via content determination. The fresh medicinal materials of Paeoniae Radix Alba collected from Bozhou of Anhui province were processed(boiled and peeled) and dried(hot air-dried, infrared-dried, and microwave-dried) at different temperatures(40, 50, 60 and 70 ℃), and the 11 components(monoterpene glycosides, polyphenols, tannin, and benzoic acid) in Paeoniae Radix Alba were determined by ultra-performance liquid chromatography coupled to triple quadrupole with electrospray tandem mass spectrometry(UPLC-TQ-MS). Then the compounds in processed and dried samples were analyzed by partial least squares discriminant analysis(PLS-DA) and orthogonal partial least squares discriminant analysis(OPLS-DA), and the contribution rates of differential components were evaluated by variable important in projection(VIP). The results indicated that the samples obtained by different processing and drying methods could be distinguished. Albiflorin, gallic acid, 1,2,3,4,6-pentakis-O-galloyl-β-D-glucose, and benzoic acid were the common differential components in boiled Paeoniae Radix Alba. Benzoic acid was the common differential component in peeled Paeoniae Radix Alba. Gallic acid was the common differential component in Paeoniae Radix Alba dried by different methods. The samples could not be distinguished after drying at different temperatures due to the lack of common differential components. This study is expected to provide a reference for the selection of processing and drying methods and the optimization of processing parameters.

ABSTRACT

The extract rates, multicomponent content and fingerprint were determined in this study to investigate the quality diffe-rence between standard decoction of raw Paeoniae Radix Alba and fried Paeoniae Radix Alba. UPLC fingerprint was established for 17 batches of standard decoction of raw and fried Paeoniae Radix Alba, and the contents of gallic acid, catechin, albiflorin, paeoniflorin and benzoyl paeoniflorin were determined. The peak areas of standard decoction were analyzed by the independent t-test and orthogonal partial least squares discriminant analysis. There was no significant difference in extract rates between the standard decoction of raw and fried Paeoniae Radix Alba. After fried processing, the content of albiflorin increased by 0.26%, while the contents of gallic acid, catechin, paeoniflorin and benzoyl paeoniflorin decreased by 13.04%, 27.97%, 10.30% and 18.79% respectively. There were 14 common peaks in the fingerprint of standard decoction of raw Paeoniae Radix Alba, and 16 common peaks in the fried Paeoniae Radix Alba. Peak 1 and peak 3 were new ones after processing, among which the peak 3 was 5-hydroxymethylfurfural. The results showed that peak 1, peak 3, peak 11 and peak 15 were the key compounds to distinguish standard decoction of raw and fried Paeoniae Radix Alba. In conclusion, this method is stable and can be used for the study of quantity transfer and quality control in the preparation process of standard decoction, granules and other dosage forms for raw and fried Paeoniae Radix Alba, providing reference for the identification of raw and fried Paeoniae Radix Alba and related preparations.

ABSTRACT

Objective:To investigate the therapeutic effect and possible mechanism of four types of Chinese herbal moisturizers made in laboratory for atopic dermatitis induced by 2,4-dinitrofluorobenzene (DNFB) in mice. Method:According to the body weight, BALA/c mice were randomly divided into normal group, model group, blank cream group (moisturizer A), Shaoyao Gancaotang group (moisturizer B), Shaoyao Gancaotang with Portulacae Herba,Ginseng Radix et Rhizoma and Honeysuckle Stem group (moisturizer C), and Shaoyao Gancaotang with Ginseng Radix et Rhizoma and Honeysuckle Stem group (moisturizer D) , with the dose of 25 g·kg-1 per day, as well as tacrolimus ointment group of 3 g·kg-1 per day, with 10 to 12 mice in each group. Except the normal group, the mice in the other groups were treated with 0.5% DNFB in the hair removal skin of back, 100 μL each for 7 days. Starting from the 7th day, each group was given the appropriate skin cream for external use intervention, once per day, for 15 consecutive days, except for the normal and the model groups. The animal body mass was measured once a week, and the animal back skin was graded three times a week, and the skin lesion score was recorded. After the mice were killed, the left and right ears were taken, the weight of both ears was punched and the degree of swelling was calculated. The back skin was fixed and stained with hematoxylin-eosin(HE) method, and then pathologic examination was conducted to observe and score the pathological changes of mouse back skin. Blood was obtained after the last dose and enzyme-linked immunosorbent assay (ELISA) was used to determine the immunoglobulin(Ig)E content in serum. Western blot was used to measure the expression of signal transduction and activator of transcription 3 (STAT3), phosphorylation (p)-STAT3 in the skin tissue. Result:Compared with the normal group, the body mass decreased continuously, a series of inflammatory changes such as erythema, edema, dryness, desquamation and callus exfoliation and so on occurred in the modeling area, and the skin lesion score increased significantly in the model group. Additionally, the cuticle of ear skin was thickened and the degree of ear swelling was obviously increased in the model group. Microscopically, the occurred changes in the model mice included the local necrosis of the epidermis, epidermal thickening, epidermal hyperplasia, and the hyperkeratosis and hypokeratosis in the cuticle, as well as the subcutaneous inflammatory cell infiltration and so on. Furthermore, the content of serum IgE andthe expression of p-STAT3 in skin tissues increased significantly in the model group. Compared with the model group, the body mass of mice in group C and D was significantly increased (P<0.01), and the skin lesion status score was decreased (P<0.05,P<0.01).The degree of auricle swelling was significantly reduced in group B, C and D compared with that in the model group (P<0.01).The degree of skin necrosis and defect and epidermal hyperplasia of mice in moisturizer C group was significantly reduced compared with that in model group (P<0.05,P<0.01). Serum IgE levels of mice in group C and D were significantly lower than those in the model group (P<0.05,P<0.01). The expression of p-STAT3 protein in skin tissues of mice in moisturizer C group was significantly lower than that in model group (P<0.05). Conclusion:The moisturizers B, C and D all have certain therapeutic effect on atopic dermatitis, among which moisturizers C has the most obvious therapeutic effect. The possible mechanism may be that it reduces the level of inflammatory cytokines by inhibiting the increase of serum IgE content and the phosphorylation of STAT3.

ABSTRACT

Trace metals deficiency or excess are associated with the etiology and pathogenesis of rheumatoid arthritis(RA). Aconiti Radix Cocta(A) and Paeoniae Radix Alba(B) are commonly used together for the treatment of RA. In this study, we aim to determine anti-arthritic-related metal bioavailability in the compatibility of herb A and B for avoiding metal deficiency or excess, and optimize the combination ratio of herb A and B, accordingly. Anti-arthritic-related metal bioaccessibility were evaluated by in vitro simulator of all gastrointestinal tract(including mouth, stomach, small and large intestines), and the roles of gastrointestinal digestive enzymes and intestinal microflora were investigated. Anti-arthritic-related metal bioavailability was assessed by the affinity adsorption with liposomes. The results indicated that compatibility proportion of corresponding herbal plants, gastrointestinal digestion and microbial metabolic, which could affect metal digestion and absorption. The optimal compatibility proportion of 1 A∶1 B is recommended, according to the dose of anti-arthritic-related metal bioavailability, which is often chosen for clinical practice of RA therapy. Thus, anti-arthritic-related metal bioavailability might be the key active substances for RA treatment.

ABSTRACT

Guizhi Decoction is a resolving agent,which is a classic prescription for traditional Chinese medicine. It is effective in the treatment of sepsis in clinical practice. However,due to the complexity of the prescription,its anti-sepsis mechanism is difficult to be clarified. The " Cinnamomi Ramulus-Paeoniae Radix Alba" drug pair,as the classic compatibility for medicinal and medicinal herbs,is the core of Guizhi Decoction. In this study,Cinnamomi Ramulus-Paeoniae Radix Alba drug pair was used as the research object and the molecular mechanism of its treatment of sepsis was investigated by analyzing the chemical compositions with integrative pharmacology platform( TCMIP,http://www.tcmip.cn/),predicting disease target,analyzing gene function and pathway of " Cinnamomi Ramulus-Paeoniae Radix Alba" in treatment of sepsis,and establishing a multi-dimensional network relationship of " Chinese medicine-chemical components-core targets-key pathways". The prediction results of " Cinnamomi Ramulus-Paeoniae Radix Alba" drug pair showed that its anti-sepsis effect was associated with 45 active components,and the active components played an anti-sepsis role through multiple targets and pathways,involving inflammatory targets such as PF4,MyD88,TLR4,BDKRB2,CD14,and NOS3. The sepsis was relieved mainly by regulating Toll like signaling pathway,Fox O signaling pathway,chemokines signaling pathway,thyroid and insulin endocrine signaling pathways and biological processes. This study provides a scientific basis for further development of Cinnamomi Ramulus-Paeoniae Radix Alba drug pair and Guizhi Decoction against sepsis.

ABSTRACT

Shenshao Tablet (SST), prepared from Paeoniae Radix Alba (PRA) and total ginsenoside of Ginseng Stems and Leaves (GSL), is a traditional Chinese medicine (TCM) preparation prescribed to treat coronary heart disease. However, its chemical composition and the components that can migrate into blood potentially exerting the therapeutic effects have rarely been elucidated. We developed an HPLC/DAD/ESI-MS approach aiming to comprehensively profile and identify both the chemical components of SST and its absorbed ingredients (and metabolites) in rat plasma and urine. Chromatographic separation was performed on an Agilent Eclipse XDB C column using acetonitrile/0.1% formic acid as the mobile phase. MS detection was conducted in both negative and positive ESI modes to yield more structure information. Comparison with reference compounds (t, MS), interpretation of the fragmentation pathways, and searching of in-house database, were utilized for more reliable structure elucidation. A total of 82 components, including 21 monoterpene glycosides, four galloyl glucoses, two phenols from PRA, and 55 ginsenosides from GSL, were identified or tentatively characterized from the 70% ethanolic extract of SST. Amongst them, seven and 24 prototype compounds could be detectable in the plasma and urine samples, respectively, after oral administration of an SST extract (4 g·kg) in rats. No metabolites were observed in the rat samples. The findings of this work first unveiled the chemical complexity of SST and its absorbed components, which would be beneficial to understanding the therapeutic basis and quality control of SST.

Shenshao Tablet (SST), prepared from Paeoniae Radix Alba (PRA) and total ginsenoside of Ginseng Stems and Leaves (GSL), is a traditional Chinese medicine (TCM) preparation prescribed to treat coronary heart disease. However, its chemical composition and the components that can migrate into blood potentially exerting the therapeutic effects have rarely been elucidated. We developed an HPLC/DAD/ESI-MS approach aiming to comprehensively profile and identify both the chemical components of SST and its absorbed ingredients (and metabolites) in rat plasma and urine. Chromatographic separation was performed on an Agilent Eclipse XDB C column using acetonitrile/0.1% formic acid as the mobile phase. MS detection was conducted in both negative and positive ESI modes to yield more structure information. Comparison with reference compounds (t, MS), interpretation of the fragmentation pathways, and searching of in-house database, were utilized for more reliable structure elucidation. A total of 82 components, including 21 monoterpene glycosides, four galloyl glucoses, two phenols from PRA, and 55 ginsenosides from GSL, were identified or tentatively characterized from the 70% ethanolic extract of SST. Amongst them, seven and 24 prototype compounds could be detectable in the plasma and urine samples, respectively, after oral administration of an SST extract (4 g·kg) in rats. No metabolites were observed in the rat samples. The findings of this work first unveiled the chemical complexity of SST and its absorbed components, which would be beneficial to understanding the therapeutic basis and quality control of SST.

ABSTRACT

Depression is a kind of mental illness accompanied by complex etiology and pathogenesis in clinic. With the quickening pace of circadian rhythm and increase of life pressure in modern society, the incidence of depression is increasing year by year. Nowadays, some typical antidepressant Western medicines, such as selective serotonin re-uptake inhibitors (SSRI) and tricyclic antidepressants (TCA), have been used as the main therapeutic drugs in clinic. Unfortunately, administration of these drugs will result in severe adverse reactions, slow treatments, and low cure rates, thus obviously they can not be used for a long term. Sini San, which originated from written by Zhang zhongjing, is a prescription widely applied in clinic for curing mental illness and also a basic Chinese herbal formula for modern treatment of depression. This article would review the research progress on antidepressant effects of Sini San based on single herbs of Bupleuri Radix and Paeoniae Radix Alba, herb-pair of Bupleuri Radix-Paeoniae Radix Alba, and formula of Sini San, providing directions and ideas for future research on complicated Chinese herbal formulae.
