ABSTRACT

In order to comprehensively evaluate the quality of Viticis Fructus, this study established HPLC fingerprints and evaluated the quality of 24 batches of Viticis Fructus samples from different species by similarity evaluation and multivariate statistical analysis(PCA, HCA, PLS-DA). On this basis, an HPLC method was established to compare the content differences of the main components, including casticin, agnuside, homoorientin, and p-hydroxybenzoic acid. The analysis was performed on the chromatographic column(Waters Symmetry C_(18)) with a gradient mobile phase of acetonitrile(A)-0.05% phosphoric acid solution(B) at the flow rate of 1 mL·min~(-1) and detection wavelength of 258 nm. The column temperature was 30 ℃ and the injection volume was 10 μL. The HPLC fingerprint of 24 batches of Viticis Fructus samples was established with 21 common peaks, and nine peaks were identified. Similarity analysis was carried out based on chromatographic data of 24 batches of chromatographic data of Viticis Fructus, and the results showed that except for DYMJ-16, the similarity of Vitex trifolia var. simplicifolia was ≥0.900, while that of V. trifolia was ≤0.864. In addition, the similarity analysis of two different species showed that the similarity of 16 batches of V. trifolia var. simplicifolia was 0.894-0.997 and that of the eight batches of V. trifolia was between 0.990 and 0.997. The results showed that the similarity of fingerprints of these two species was different, but the similarity between the same species was good. The results of the three multivariate statistical analyses were consistent, which could distinguish the two different species. The VIP analysis results of PLS-DA showed that casticin and agnuside contributed the most to the distinction. The content determination results showed that there was no significant difference in the content of homoorientin and p-hydroxybenzoic acid in Viticis Fructus from different species, but the content of casticin and agnuside was significantly different in different species(P<0.01). The content of casticin was higher in V. trifolia var. simplicifolia, while agnuside was higher in V. trifolia. The findings of this study show that there are differences in fingerprint similarity and component content of Viticis Fructus from different species, which can provide references for the in-depth study of the quality and clinical application of Viticis Fructus.

ABSTRACT

An UPLC-MS/MS method was developed to simultaneously determine complanatoside A and complanatoside B in rat plasma with rutin as the internal standard and applied to examine the effect of salt-processing on pharmacokinetics of these two flavonoid glycosides. The pharmacokinetic parameters were estimated using DAS 3.2.6 and subjected to independent sample t-test with SPSS 23.0. No significant difference in T_(max) of complanatoside B was observed between the raw and processed groups; however, in the processed group, C_(max) and AUC_(0-12 h) of complanatoside B increased obviously(P<0.05), while MRT_(0-12 h) decreased from(3.34±0.44) h to(1.81±0.36) h(P<0.05). C_(max) [(14.72±11.13) μg·L~(-1)] and MRT_(0-24) [(3.93±0.26) h] of complanatoside A in the raw group were statistically different from those [(35.64±21.99) μg·L~(-1),(1.43±0.24) h] in the processed group(P<0.05). As a result, salt-processing can facilitate the in vivo adsorption and accelerate the excretion of complanatoside A and complanatoside B.

ABSTRACT

Objective:To study the quality evaluation method of Cyperi Rhizoma processed with four excipients. Method:Ultra-performance liquid chromatography (UPLC) fingerprints of raw products and processed products with four excipients of Cyperi Rhizoma were established, and the changes of chemical components in the fingerprints before and after processing were compared by chemometric analysis. The mobile phase was consisted of methanol (A)-water (B) for gradient elution (0-10 min, 5%-40%A; 10-30 min, 40%-70%A; 30-40 min, 70%A) at a flow rate of 0.3 mL·min<sup>-1</sup>. The injection volume was 3 μL, the column temperature was 35 ℃, and the detection wavelength was 280 nm. The content changes of main index components in Cyperi Rhizoma before and after processing were compared by UPLC. The mobile phase was methanol-water (75∶25) and the detection wavelength was 242 nm. Result:Processing with four excipients had a significant impact on the overall characteristics of chemical components in the fingerprint of Cyperi Rhizoma. A total of 28 characteristic peaks were identified in fingerprints of the raw and processed products. Among them, peaks 1, 2 and 4 were specific peaks of the processed products, peak 5 was characteristic peak of the raw products. Peak 2 was identified as 5-hydroxymethylfurfural, peak 24 as cyperenone and peak 27 as <italic>α</italic>-cyperone. The 5-hydroxymethylfurfural produced by the processing with four excipients came from rice vinegar, rice wine and Maillard reaction of polysaccharides in Cyperi Rhizoma. The results of determination showed that there was no significant difference in the content of cyperenone after processing, but the content of <italic>α</italic>-cyperone decreased significantly. Conclusion:In the process of Cyperi Rhizoma processed with four excipients, there are new components produced by structural transformation, which are accompanied by changes in the content of index components. In this study, the quality of raw and processed products of Cyperi Rhizoma can be rapidly and effectively evaluated from qualitative and quantitative aspects.

ABSTRACT

Objective:To investigate the effective constituents and mechanism of Tingli Dazao Xiefeitang for the treatment of heart failure through network pharmacology and high resolution mass spectrometry technique as well as molecular docking technique. Method:Chemical components and potential targets in Descurainiae Semen Lepidii Semen and Jujubae Fructus were searched by referring to literature and BATMAN-TCM database. The disease targets were searched in GeneCards database with ''heart failure'' as the key word. STRING platform was used to construct protein-protein interaction(PPI) network based on common targets of drugs and disease. The network topology was analyzed by using Cytoscape 3.7.2 software to obtain the core targets eventually. Kyoto encyclopedia of genes and genomes(KEGG) enrichment analysis of the core targets was conducted through DAVID database to draw a network of “herb-compound-target-pathway”. Based on the results of the network pharmacology research above,high resolution mass spectrometry was used to analyze the decoction and confirm the selected active components. AutoDock 4.2.6 software was used for molecular docking verification of key active components and related targets. Result:A total of 85 components were obtained in Descurainiae Semen Lepidii Semen,and 49 components were obtained in Fructus Ziziphi Jujubae. A total of 1 078 drug targets and 1 549 disease targets were identified. After PPI analysis and network topology analysis,23 core targets and 33 active components were obtained,involving 19 signaling pathways (<italic>P</italic><0.05). Mass spectrometry analysis results indicated that 18 components such as isovanillic acid,descuraininA and kaempferol-7-<italic>O-β-D</italic>-glucopyranoside were confirmed in decoction. Molecular docking analysis results indicated that 6 core components (degree value top 6),such as isovanillic acid,descurainin A and kaempferol-7-<italic>O-β-D</italic>-glucopyranoside,had good binding activity with silent information regulatory factor 1(SIRT1),interleukin(IL)1B,protein kinase B<italic>α</italic>(AKT1) and tumor necrosis factor(TNF). The compound recipe for heart failure mainly involved mitogen-activated protein kinase(MAPK),hypoxia inducible factor-1(HIF-1),Mammalian target of rapamycin(mTOR) and other signaling pathways. Conclusion:This study preliminarily investigated the effective constituents and mechanism of Tingli Dazao Xiefeitang in the treatment of heart failure. It can provide references for the precise clinical medication and screening of quality control markers,as well as the discovery of active components in the treatment of heart failure.

ABSTRACT

Objective::To study on the content change and transformation rule of eight main characteristic components in stir-frying process of Glycyrrhizae Radix et Rhizoma. Method::The contents of liquiritin apioside, liquiritin, isoliquiritin apioside, isoliquiritin, liquiritigenin, isoliquiritigenin, glycyrrhizic acid and glycyrrhetinic acid in Glycyrrhizae Radix et Rhizoma were determined simultaneously by HPLC. The chromatographic conditions were Waters Symmetry® C18 column (4.6 mm×250 mm, 5 μm), and the mobile phase of acetonitrile (A)-0.05%phosphoric acid solution (B) for gradient elution (0-9 min, 19%-25%A; 9-18 min, 25%-34%A; 18-38 min, 34%-51%A; 38-58 min, 51%-89%A), the flow rate of 1 mL·min-1, the detection wavelengths at 320 nm (0-16 min), 276 nm (16-25 min), 370 nm (25-28 min), 254 nm (28-58 min), the injection volume of 10 μL and the column temperature at 30 ℃. Result::After stir-frying, the total content of three components with dihydroflavone as mother nucleus was decreased, while the total content of three components with chalcone as mother nucleus showed an upward trend, the content change of glycyrrhizic acid was not obvious, but glycyrrhetinic acid content showed a slight upward trend. When the monomer heating temperature reached 130 ℃, dihydroflavones and chalcones could be isomerized with each other, and with the increase of temperature, the isomerization became more obvious. When the heating temperature rose to 180 ℃ (isoliquiritin apioside was 130 ℃), in addition to the isomerization, the glucosidic bond of flavonoid glycosides began to break and gradually transformed into the corresponding secondary glycosides or aglycones. Glucosidic bond of glycyrrhizic acid could also be broken to form glycyrrhetinic acid, which was detected at 150 ℃. Conclusion::The change of chemical composition is complex during stir-frying process of Glycyrrhizae Radix et Rhizoma, in addition to the isomerization and glucosidic bonds breaking observed in this experiment, there may be other complex reactions. The content of one compound in the herb is affected by many factors during its processing, such as the time and temperature of frying, the stability of the compound itself and so on.

ABSTRACT

To clarify the change and development of original plants of " Manjingzi"( Viticis Fructus),a traditional Chinese medicine,we investigated Vitex species on the ancient Chinese herbal texts. The study concluded that the Vitex trifolia and V. trifolia var.simplicifolia included in the Chinese Pharmacopoeia( 2015 edition) are only two sources of ancient medicinal Viticis Fructus. There are many sources of vines used in ancient times,which are not fixed and unified. The early use of Viticis Fructus is likely to be the V. quinate var. quinata,V. negundo var. cannabifolia and V. negundo var. negundo. From the Tang Dynasty,the use of V. trifolia var. simplicifolia has been appeared. Until Li Shizhen of the Ming Dynasty,the V. trifolia has been used as a source of medicine for the Viticis Fructus,but even so,the source of medicinal plants of Viticis Fructus has not been unified. We suggested V. trifolia var. simplicifolia be used as mainly species for " Manjingzi" due to its widely used in ancient China.

ABSTRACT

References and our previous experiment showed that the contents of glycosides were significantly decreased,while the contents of aglycones were significantly increased after processing of Cassiae Semen.It may be related to its glycosidases or the heating process. In order to investigate the reasons, high performance liquid chromatographic (HPLC) was used to study the effects of these two factors on contents of Cassiae Semen's main chemical components in processing. The results showed that glycoside hydrolases was present in Cassiae Semen and could rapidly hydrolyze glycosides from Cassiae Semen into aglycones in suitable temperature with sufficient water.However,it didn't show effect on contents change of main constituents in the procedure of Cassiae Semen processing.The reason for content decrease of glycosides and content increase of aglycones in processed Cassiae Semen was glycoside bond cracking to produce corresponding aglycone at high temperature.This study further provides basis for further revealing of the processing mechanism of Cassiae Semen.

ABSTRACT

<p><b>OBJECTIVE</b>To establish a method for determining the content of rubrofusarin gentiobioside in Cassia obtusifolia.</p><p><b>METHOD</b>The HPLC with Diamonsil C18 (4.6 mm x 250 mm, 5 microm) column was used, acetonitrile-THF-1% acetic acid (18: 3:79) was used as a mobile phase, with flow rate of 1 mL x min(-1), column temperature at 40 degrees 2 and detection wavelength at 278 nm.</p><p><b>RESULT</b>A good linearity was obtained from 0.1-0.5 microg with r = 0.999 9 for rubrofusarin gentiobioside. The average recovery was 101.1%, and RSD was 2.23% (n = 5).</p><p><b>CONCLUSION</b>The method was proved to be simple, rapid, sensitive, precise, reliable and repeatable. It can be applied to the quality control of Semen Cassia.</p>
