Optimization of parameters for stir-frying of Kansui Radix with vinegar based on conversion of toxic components

This study aims to optimize the parameters for stir-frying of Kansui Radix with vinegar based on the conversion of representative toxic diterpenes, which is expected to serve as a reference for the standardized production of Kansui Radix stir-fried with vinegar. To be specific, the toxic components [3-O-(2'E,4'Z-decadienoyl)-20-O-acetylingenol(3-O-EZ), kansuiphorin C(KPC)] in Kansui Radix and the products(ingenol, 20-deoxyingenol) after the stir-frying with vinegar were selected. The toxicity to intestine and water-draining activity were evaluated with NCM460(normal human colon mucosal epithelial cell line) and HT-29(a human colorectal adenocarcinoma cell line). An HPLC method was then developed to assess the conversion of toxic components. On this basis, temperature, time, and amount of vinegar for the processing of Kansui Radix were optimized with the Box-Behnken design and the content of ingenol and 20-deoxyingenol as evaluation index. The results showed that after the stir-frying of Kansui Radix with vinegar, 3-O-EZ and KPC were first converted to monoester 3-O-(2'E,4'Z-decadienoyl)ingenol(3-EZ) and 5-O-benzoyl-20-deoxyingenol(5-O-Ben) and finally to almost non-toxic ingenol and 20-deoxyingenol, respectively. Meanwhile, the water-draining activity was retained. Six compounds had a good linear relationship with the peak area in the corresponding concentration ranges(R~2≥0.999 8), and the average recovery fell in the range of 98.20%-102.3%(RSD≤2.4%). The content of representative diterpenes and intermediate products was 14.78%-24.67% lower in the Kansui Radix stir-fried with vinegar than in the Kansui Radix, while the content of the conversed products was 14.37%-71.37% higher. Among the process parameters, temperature had significant influence on the total content of products, followed by time. The optimal parameters were 210 ℃, 15 min, and 30% vinegar. The relative error between the experimental results and the predicted values was 1.68%, indicating that the process was stable and reproducible. The strategy of screening optimal parameters for stir-frying of Kansui Radix with vinegar based on the transformation of toxic components can help improve the production stability, reduce the toxicity, and ensure the efficacy of Kansui Radix stir-fried with vinegar, which can serve as a reference for the process optimization of similar toxic Chinese medicinals.

Jujubae Fructus alleviates intestinal injury caused by toxic medicinals in Shizao Decoction based on correlation between intestinal flora and host metabolism

Genkwa Fols, Kansui Radix, and Euphorbiae Pekinensis Radix in Shizao Decoction(SZD) are toxic to intestinal tract. Jujubae Fructus in this prescription can alleviate the toxicity, but the mechanism is still unclear. Therefore, this study aims to explore the mechanism. To be specific, 40 normal Sprague-Dawley(SD) rats were classified into the normal group, high-dose and low-dose SZD groups, and high-dose and low-dose SZD without Jujubae Fructus(SZD-JF) groups. The SZD groups were given(ig) SZD, while SZD-JF groups received the decoction without Jujubae Fructus. The variation of body weight and spleen index were recorded. The patho-logical changes of intestinal tissue were observed based on hematoxylin and eosin(HE) staining. The content of malondialdehyde(MDA) and glutathione(GSH) and activity of superoxide dismutase(SOD) in intestinal tissue were measured to evaluate the intestinal injury. Fresh feces of rats were collected to detect intestinal flora structure by 16S ribosomal RNA gene(16S rDNA) sequencing technology. The content of fecal short chain fatty acids and fecal metabolites was determined by gas chromatography-mass spectrometer(GC-MS) and liquid chromatography-mass spectrometer ultra-fast liquid chromatography-quadrupole-time-of-flight mass spectrometer(UFLC-Q-TOF-MS), separately. Spearman's correlation analysis was employed to analyze the differential bacteria genera and differential metabolites. RESULTS:: showed that high-dose and low-dose SZD-JF groups had high content of MDA in intestinal tissue, low GSH content and SOD activity, short intestinal villi(P<0.05), low diversity and abundance of intestinal flora, variation in the intestinal flora structure, and low content of short chain fatty acids(P<0.05) compared with the normal group. Compared with high-dose and low-dose SZD-JF groups, high-dose and low-dose SZD groups displayed low content of MDA in intestinal tissue, high GSH content and SOD activity, recovery of the length of intestinal villi, increased abundance and diversity of intestinal flora, alleviation of dysbacteria, and recovery of the content of short chain fatty acids(P<0.05). According to the variation of intestinal flora and fecal metabolites after the addition of Jujubae Fructus, 6 differential bacterial genera(Lactobacillus, Butyricimonas, Clostridia＿UCG-014, Prevotella, Escherichia-Shigella, Alistipes),4 differential short chain fatty acids(such as acetic acid, propionic acid, butyric acid, valeric acid) and 18 differential metabolites(such as urolithin A, lithocholic acid, and creatinine) were screened out. Beneficial bacteria such as Lactobacillus were in positive correlation with butyric acid and urolithin A(P<0.05). The pathogenic bacteria such as Escherichia-Shigella were in negative correlation with propionic acid and urolithin A(P<0.05). In summary, SZD-JF caused obvious intestinal injury to normal rats, which could lead to intestinal flora disorder. The addition of Jujubae Fructus can alleviate the disorder and relieve the injury by regulating intestinal flora and the metabolites. This study discusses the effect of Jujubae Fructus in relieving the intestinal injury caused by SZD and the mechanism from the perspective of intestinal flora-host metabolism, which is expected to serve as a reference for clinical application of this prescription.

Effect of Kansui Radix stir-fried with vinegar on fecal metabolomics in Walker-256 rats with ascites

Utilizing metabolomics technology, this study explored the change of fecal endogenous metabolites in Walker-256 rats with malignant ascites after the administration with Kansui Radix(KR) stir-fried with vinegar(VKR), sought the potential biomarkers in feces which were related to the treatment of malignant ascites by VKR and revealed the biological mechanism of water-expelling effect of VKR. Ultra-fast liquid chromatography-quadrupole-time-of-flight mass spectrometry(UFLC-Q-TOF-MS) was employed to detect the feces of rats in all groups. Principle component analysis(PCA) and partial least squares discriminant analysis(PLS-DA) were conducted to achieve pattern recognition. Combining t-test and variable importance in the projection(VIP) enabled the screening of potential biomarkers for the malignant ascites. Metabolic pathway analysis was accomplished with MetaboAnalyst. Correlation analysis was finally conducted integrating the sequencing data of gut microbiota to elucidate the mechanism underlying the water-expelling effect of VKR. The results showed that both KR and VKR could restore the abnormal metabolism of model rats to some extent, with VKR being inferior to KR in the regulation. Eleven potential biomarkers were identified to be correlated with the malignant ascites and five metabolic pathways were then enriched. Four kinds of gut microbiota were significantly related to the potential biomarkers. The water-expelling effect of VKR may be associated with the regulation of phenylalanine metabolism, biosynthesis of phenylalanine, tyrosine and tryptophan, tryptophan metabolism, glycerophospholipid metabolism, and glycosylphosphatidylinositol(GPI)-anchor biosynthesis. This study can provide a scientific basis for comprehensive understandings of the interaction between gut microbiota and host which has relation to the water-expelling effect of VKR and guide the reasonable clinical application of VKR.

Components of drugs in acupoint sticking therapy and its mechanism of intervention on bronchial asthma based on UPLC-Q-TOF-MS combined with network pharmacology and experimental verification

UPLC-Q-TOF-MS combined with network pharmacology and experimental verification was used to explore the mechanism of acupoint sticking therapy(AST) in the intervention of bronchial asthma(BA). The chemical components of Sinapis Semen, Cory-dalis Rhizoma, Kansui Radix, Asari Radix et Rhizoma, and Zingiberis Rhizoma Recens were retrieved from TCMSP as self-built database. The active components in AST drugs were analyzed by UPLC-Q-TOF-MS, and the targets were screened out in TCMSP and Swiss-TargetPrediction. Targets of BA were collected from GeneCards, and the intersection of active components and targets was obtained by Venny 2.1.0. The potential targets were imported into STRING and DAVID for PPI, GO, and KEGG analyses. The asthma model induced by house dust mite(HDM) was established in mice. The mechanism of AST on asthmatic mice was explored by pulmonary function, Western blot, and flow cytometry. The results indicated that 54 active components were obtained by UPLC-Q-TOF-MS and 162 potential targets were obtained from the intersection. The first 53 targets were selected as key targets. PPI, GO, and KEGG analyses showed that AST presumedly acted on SRC, PIK3 CA, and other targets through active components such as sinoacutine, sinapic acid, dihydrocapsaicin, and 6-gingerol and regulated PI3 K-AKT, ErbB, chemokine, sphingolipid, and other signaling pathways to intervene in the pathological mechanism of BA. AST can improve lung function, down-regulate the expression of PI3 K and p-AKT proteins in lung tissues, enhance the expression of PETN protein, and reduce the level of type Ⅱ innate immune cells(ILC2 s) in lung tissues of asthmatic mice. In conclusion, AST may inhibit ILC2 s by down-regulating the PI3 K-AKT pathway to relieve asthmatic airway inflammation and reduce airway hyperresponsiveness.

Chemical ingredient groups B and C in Kansui Radix stir-fried with vinegar affect diversity of gut microbiota in rat model of malignant ascites induced by Walker-256 cells

This study aims to explore the effects of chemical ingredient groups B and C in Kansui Radix stir-fried with vinegar on the diversity of gut microbiota in the rat model of malignant ascites, identify the key differential microbial taxa, and reveal the biological mechanism of water-expelling effect of the two chemical ingredient groups. The rat model of malignant ascites induced by Walker-256 cells was established, and phenolphthalein was used as the positive drug. The rats were orally administrated with corresponding agents for consecutive 7 days. On day 6, fresh feces samples were collected from the rats, and 16 S rDNA high-throughput sequencing and GC-MS were employed to determine the composition of gut microbiota and the content of short-chain fatty acids, respectively. On day 7, serum and intestinal tissue samples were collected for the determination of related indicators. Compared with the control group, the model group showed decreased feces volume and urine volume(P<0.01), increased volume of ascites and levels of Na~+, K~+, and Cl~- in urine(P<0.01), down-regulated mRNA and protein levels of intestinal AQP8(P<0.01), lowered abundance of beneficial Lactobacillus(P<0.01) while risen abundance of potential pathogenic Lachnospiraceae and Anaeroplasma(P<0.01), and reduced content of short-chain fatty acids(P<0.01). Compared with the model group, administration with chemical ingredient groups B and C alleviated all the above indicators(P<0.01). In conclusion, chemical ingredient groups B and C in Kansui Radix stir-fried with vinegar could alleviate the disordered gut microbiota in rats with malignant ascites to expel water through increasing the abundance of beneficial Lactobacillus and reducing the abundance of harmful Lachnospiraceae and Anaeroplasma. This study can provide a reference for the reasonable clinical application of Kansui Radix stir-fried with vinegar.

Preliminary investigation on processing mechanism of Kansui Radix by liquorice based on thermal analysis technology

In the thermal analysis, the pyrolysis characteristics of crude Kansui Radix, alcohol extract of Kansui Radix, petroleum ether extract, chloroform extract, ethyl acetate extract, n-butanol extract, and licorice vinegar were analyzed with simulated air (N₂-O₂ 4:1) as the carrier gas, at a temperature increase rate of 10 °C·min⁻¹ and a volume flow rate of 60 mL·min⁻¹, respectively. The results showed that due to the different polarity of the extraction solvent, the type and quantity of the chemical components contained in each polar part were different, and with the increase in the amount of solid powder of licorice, the peak of the maximum heat loss rate occurred in advance. For petroleum ether, chloroform, and ethyl acetate fractions, (157.40±1.06), 3.50, (25.83±1.66) °C in advance respectively, but the weight loss rate of the chloroform fraction was increased by (2.62±5.19) °C, while decreased by (33.90±1.72), (19.28±1.11) °C for the petroleum ether and ethyl acetate fractions. So we can conclude that with the addition of licorice, the pyrolysis rate of the petroleum ether and chloroform fractions in the toxic part of Kansui Radix was increased; the temperature point at the peak of the maximum weight loss rate was decreased, and the ethyl acetate fraction (effective part) showed a decrease in temperature rising process, but its overall ratio of weight loss and weight loss rate were relatively small, retaining the effect of medicinal ingredients. This proved the mechanism of licorice system Kansui Radix on attenuating toxicity after processing and the scientificity and rationality of licorice system Kansui Radix. At the same time, as the proportion of glycyrrhizin was increased, the peak of the maximum heat loss rate of petroleum ether, chloroform and ethyl acetate fractions occurred in advance; the peak temperature was decreased, with easy pyrolysis. Among them, the thermogravimetric rate of the mixture of petroleum ether and chloroform fractions (10:1) was relatively large, with a low peak temperature, while ethyl acetate fraction showed opposite results. This conclusion has certain guiding significance for the ratio of gansui to licorice.

Therapeutic Effects of Methanol Extract from Euphorbia kansui Radix on Imiquimod-Induced Psoriasis.

The roots of Euphorbia kansui, which belong to the family Euphorbiaceae, have been used as a traditional medicine for the treatment of various diseases such as diabetes, ascites, and leukemia. Recently, it was reported that the methylene chloride fraction of E. kansui radix (EKC) regulated the differentiation of Th17 cells and alleviated the symptoms of Th17-related inflammatory bowel disease. Imiquimod (IMQ), a TLR7/8 agonist, has been used to induce psoriasis in a mouse model. In this study, we evaluated the effect of EKC in an IMQ-induced psoriasis model. EKC effectively inhibited the production of interleukin-17A and interferon-γ in vitro. On this basis, EKC was administered to an animal model of psoriasis. Acanthosis and the infiltration of inflammatory cells into the dermis were significantly reduced by EKC. EKC also inhibited the expression of IL-17A, IL-22, IL-23, IL-12, and RAR-related orphan receptor gamma t (RORγt) in the spleen, skin-draining lymph nodes, and the skin. Additionally, EKC inhibited the activity of dendritic cells but not that of keratinocytes. In conclusion, EKC ameliorated the symptoms of psoriasis through inhibition of Th17 differentiation and activation of dendritic cells. These effects are expected to be beneficial in the treatment and prevention of psoriasis.

Euphorbia kansui Attenuates Insulin Resistance in Obese Human Subjects and High-Fat Diet-Induced Obese Mice.

Background Obesity is a main cause of insulin resistance (IR), metabolic syndrome, and fatty liver diseases. This study evaluated Euphorbia kansui radix (Euphorbia) as a potential treatment option for obesity and obesity-induced IR in obese human and high-fat diet- (HFD-) induced obese mice. Methods In the human study, we analyzed the body weight change of 14 patients who took a single dose of 6 g of Euphorbia powder. In the animal study, male mice were divided into three groups: normal chow, HFD, and Euphorbia (high-fat diet and 100 mg/Kg Euphorbia once per week). Body weight, epididymal fat pad weight, fasting blood glucose, fasting insulin, HOMA-IR, and oral glucose tolerance test were measured. Also, macrophage infiltration and expression of CD68, tumor necrosis factor- (TNF-) α, interferon- (IFN-) γ, and interleukin- (IL-) 6 genes in the liver and adipose tissue were analyzed. Results The human study showed that Euphorbia has a potential effect on body weight loss. In the in vivo study, body weight, epididymal fat weight, glucose level, IR, expression of CD68, TNF-α, IFN-r, and IL-6 genes, and macrophages in liver and adipose tissue were significantly reduced by Euphorbia. Conclusions These results suggest that Euphorbia attenuates obesity and insulin resistance via anti-inflammatory effects.

Colon-derived uremic biomarkers induced by the acute toxicity of Kansui radix: A metabolomics study of rat plasma and intestinal contents by UPLC-QTOF-MS(E).

Kansui radix (KR) is a poisonous Chinese herbal medicine recorded in the Chinese Pharmacopoeia, and the acute toxicity obstructs its clinical applications. To explore its acute toxicity mechanism to enhance clinical safety, a metabolomics study based on UPLC-ESI-QTOF-MS(E) was performed. Wistar rats were exposed for 4h to the aqueous and ethyl acetate extracts prepared from KR at a high dose (25g/kg). The contents of six different sections of rat intestine, including the duodenum, jejunum, ileum, cecum, colon, and rectum were collected as samples for the first time, as well as the rat plasma. The interesting results showed that only those rats exposed to the ethyl acetate extract showed a watery diarrhea, similar to the observed acute human toxicity. The identified biomarkers found in the plasma, such as phenol sulfate, indoxyl sulfate, and p-cresol sulfate were significantly perturbed in the rats. These biomarkers are known as colon-derived uremic compounds, which were first reported with respect to KR. The three essential amino acids which produced these biomarkers were only found in the contents of colon and rectum. A hypothesis was proposed that only the colon-derived uremic compounds induced by KR might be responsible for the acute toxicity. Three traditional process methods to reduce the toxicity of KR were compared based on these biomarkers, and different levels of toxicity modulation were observed. These results may be helpful to further understand the mechanism of acute toxicity, and the relevance of the traditional process methods to ameliorate the adverse effects of KR.

Filtration of active fractions with function of expelling water retention with drastic purgative from Kansui Radix stir-baked with vinegar

To study the function of expelling water retention with drastic purgative of different polarities of Kansui Radix stir-baked with vinegar on the cancerous ascites model rats, the furosemide was taken as positive control drug, and the cancerous ascites model rats were respectively orally administered with different polarities of Kansui Radix stir-baked with vinegar for 7 d. The amount of urine and ascites, the level of urinary sodium, potassium, chloride ion and pH, and the content of PRL1, AII, ALD in serum were investigated. Compared with model groups, ethyl acetate extract group showed a decreasing trend in ascites; the amount of urine of showed a significant increase (P < 0.05); the level of urinary sodium, potassium, chloride ion (P < 0.05, P < 0.01), pH (P < 0.05), and the content of PRL1, AII, ALD in serum all showed a significant decrease (P < 0.01). The effects of petroleum ether extract and n-butanol extract were weaker than that of ethyl acetate extract. The water exact was the weakest. The results showed that ethyl acetate extract is the active part of Kansui Radix stir-baked with vinegar on the function of expelling water retention with drastic purgative on the cancerous ascites model rats, alleviating the water-electrolyte disorder and body fluid acid-base imbalance, regulating the renin angiotensin aldosterone system.

Effect of Xianxiong decoction on acute lung injury mice induced by lipopolysaccharide

To investigate the effect of Xianxiong decoction on the mice with acute lung injury induced by lipopolysaccharide. Eighty female ICR mice were randomly divided into 8 groups: model group, Xianxiong decoction group, Daxianxiong decoction group, Xianxiong decoction group without Kansui Radix group, Xianxiong decoction group without Glycyrrhizae Radix et Rhizoma group, Glycyrrhizae Radix et Rhizoma and Kansui Radix group, normal group and control group. Animals of each group, except normal group, were undertaken intraperitoneal injection and intranasal inhalation of lipopolysaccharide (LPS) on day 1, 2, 3 to establish acute lung injury (ALI) model. 30 min after modeling, 0.2 mL corresponding drugs were administrated to each mice, dexam ethasone and normal saline were given to the mice of control group and normal group respectively. White blood cell in blood, neutrophil percentage of blood and bronchoalveolar lavage fluid (BALF) supernatant, the ratio of wet and dry lung tissue ( W/D), histopathological changes of lung tissue were estimated. Sixty ICR mice were randomly divided into normal, model, control, high, middle and low dose Xianxiong decoction groups and were modeled in the same way. ELISA was applied to detect the level of NF-kappaB, TNF-alpha and IL-6 in BALF, PCR for NF-kappaB and TNF-alpha mRNA in lung tissue, and Western blot for NF-kappaB and TNF-alpha. Half of 20 ICR mice were administrated with Xianxiong decoction of its maximum tolerant normal saline. Compared with model group, the number of WBC in blood of Xianxiong decoction group mice decreased (P < 0.01), percentage of neutrophils in both blood and BALF decreased as well (P < 0.01, P < 0.05); it also significantly reduced the ratio of W/D (P < 0.01); and found the alveolar wall, the number of inflammatory cells infiltrating improved, compared with model group. Xianxiong decoction reduced the level of NF-kappaB, TNF-alpha and IL-6 in BALF (P < 0.01, P < 0.01, P < 0.05); its high and low dose groups only found TNF-alpha level declined. Five mice died 24 h after administration of Xianxiong decoction which indicated its toxicity when other influential factors were considered. Xianxiong decoction is effective on the ALI mice induced by LPS, but it is of toxicity at 3 g x mL(-1).

Dosage-toxicity-efficacy relationship of Kansui Radix in malignant pleural effusion models based on Walker 256 analysis

To investigate the dosage-toxicity-efficacy relationship of Kansui Radix, explore its regularity of the toxicity and efficacy change, and provide scientific basis for its clinical rational application, the malignant pleural effusion models were used to observe the effect of Kansui Radix with larger dose range (0.045-1.620 g•kg•d⁻¹ for Kansui Radix) on biochemical indexes and hydrothorax volume in experimental animals. Factor analysis method was also used to comprehensively assess the dosage-toxicity-efficacy relationship of Kansui Radix. The results showed that the rats in model group had larger hydrothorax volume, and ALT, AST, LDH, HBDH, IFN-γ, IL-2 and TNF-α levels were significantly increased (P<0.05), while TP and ALB levels were decreased (P<0.05) as compared with the blank group. After drug administration, various treatment groups decreased hydrothorax volume, IFN-γ, IL-2, TNF-α and increased TP and ALB levels as compared with model group, indicating certain therapeutic effect; and increased ALT, AST, LDH and HBDH levels, indicating certain liver and cardiac toxicity. In the factor analysis, two common factors were extracted from nine indexes, explaining 89.1% of the information. The analysis results suggested that there was no obvious toxicity in case of independent use of Kansui Radix within the dosage range set in pharmacopeia, while it would produce liver toxicity and cardiac toxicity upon 3 times of the dosage set in pharmacopeia, and the toxicity was increased with the increase of dose. At the same time, Kansui Radix can decrease the hydrothorax volume in malignant pleural effusion models and improve relevant physical indexes in a dose-dependent manner. Comprehensive analysis results of its toxic effect characteristics indicated that the upper-limit dose of Kansui Radix in pharmacopeia shall be regarded as the relatively optimal therapeutic dose.

A single, multi-faceted, enhanced strategy to quantify the chromatographically diverse constituents in the roots of Euphorbia kansui

Kansui radix is a famous poisonous traditional Chinese medicine. However, due to its different types of constituents with broad polarity, a variety of UV absorptions and lack of the reference standards, it was difficult to simultaneously determine the main component in kanui radix. A single, multi-faceted, enhanced strategy, exogenous reference standard – single standard to determine multi-components method (ERS-SSDMC), was proposed. Thirteen major components of kansui radix, including three jatrophane diterpenoids, eight ingenane diterpenoids and two triterpenes, among which there were three pairs of isomers, were simultaneously assayed. A C8 column, packed with 2.7μm core–shell particles, was optimized to separate these constituents in 25min on HPLC instrument detected at a program wavelength. Ethyl benzoate employed as single exogenous reference standard. The method was fully validated with respect to linearity (r2>0.9995), LOQs (0.1–0.4μg/mL), precision, accuracy (92–114%, RSD<4.4%) and stability. The robustness of the method was performed by Plackett–Burmantest tests which eight primary chromatographic parameters were investigated. It was found that the two factors, wavelength and flow rate, should be strictly controlled. A total of 75 batches of kansui radix and its three different processing products were successfully analyzed and discriminated by applying the proposed method. This work demonstrates an effective strategy for the SSDMC method making the simultaneous assay of complex multi-component TCM system achievable.
