ABSTRACT

Ephedrae Herba is a commonly used medicine for dispersing wind and cold, which has a long medicinal history. By referring to the herbal literature, medical books and prescription books, this paper intends to carry out herbal textual research on the name, origin, medicinal part, producing area, harvesting and processing methods of Ephedrae Herba in famous classical formulas, in order to provide the basis for the development of relevant famous classical formulas. According to textual research, the main base of ancient Ephedrae Herba was Ephedra sinica. The medicinal part is the herbaceous stems of Ephedrae Herba. Before the Northern and Southern dynasties, the origin of the records was Jindi and Hedong, which is now Shanxi province. In the Northern and Southern dynasties and later generations, the producing area expanded, and now it is mainly distributed in Hebei, Shanxi, Shaanxi, Inner Mongolia, Gansu, Liaoning and other places, among which Inner Mongolia is the main producing area. The harvesting and processing methods in the past dynasties are to harvest the stems in autumn, dry them in the shade or air to 70%-80% dry, and then dry them in the sun. The processing methods in the past dynasties mainly include removing the knots, wine-fried, honey-fried, processing with vinegar and so on, at present, only honey-fried is still in use. Based on the research results, it is suggested that Ephedrae Herba in famous classical formulas should be selected the dry herbaceous stems of E. sinica. If the processing requirements are not indicated, it is suggested to use raw products of Ephedrae Herba.

ABSTRACT

OBJECTIVE:To provide reference for elucidating the anti-allergic asthma constituents in alkaloids-free part of Ephedrae Herba. METHODS :Ephedrae Herba was extracted with 85% ethanol and n-heptane,and then subjected to solid-phase extraction(filler AC 18)for pretreatment to enrich alkaloids-free part from the extract of Ephedrae Herba. HPLC method was adopted,and alkaloids-free fractions of Ephedrae Herba were performed on Unitary C 18 column and Eclipse XDB-C 18 column. Using high expression G protein coupled-receptor 35(GPR35 receptor)in HT- 29 cell as target ,GPR35 receptor agonist zaprinast (1 μmol/L)as positive control ,DMR response value as the detection index ,the agonistic and desensitizing activity of each fraction(100 μg/mL)on GPR 35 receptor was screened by label-free integrated pharmacological method ,so as to screen active anti-allergic asthma fraction. HPLC-Q-TOF-MS method was used to identify the chemical composition of the selected active fractions. RESULTS :The alkaloids-free part of Ephedrae Herba was divided into two parts ,involving the precipitated part before solid phase extraction and the 95% methanol elution part ;from them ,20 fractions were screened. Among them ,the precipitated fraction F 1.5-F1.10 and 95% methanol eluted fraction F 2.5-F2.10 had a strong agonistic activity on GPR 35 receptor;at the same time,GPR35 receptor agonist zaprinast showed a relatively strong desensitization activity. The signal intensity of DMR induced by F1.5-F1.10 in the precipitated part of HT- 29 cells was even higher than that of reference drug zaprinast. By HPLC-Q-TOF-MS analysis,24 chemical components were identified from active fractions ,involving 14 flavonoids,2 volatile oils ,7 organic carboxylic acids ,1 anthraquinones. CONCLUSIONS :The alkaloid-free part of Ephedrae Herba is mainly flavonoids and has anti-allergic asthma activity.

ABSTRACT

Objective: To predict the active constituents and targets of Guizhi Shaoyao Zhimu Decoction (GSZD) in the treatment of rheumatoid arthritis by using molecular docking and network pharmacology, and to analyze the effect of multi component-multi target-multi pathway combined with the theory of compatibility of TCM prescriptions. Methods: The main chemical constituents of nine kinds of Chinese herbal medicines (Cinnamomi Ramulus, Paeoniae Radix Alba, Anemarrhenae Rhizoma, Glycyrrhizae Radix et Rhizoma, Ephedrae Herba, Zingiberis Rhizoma Recens, Atractylodis Macrocephalae Rhizoma, Saposhnikoviae Radix and Aconiti Lateralis Radix Praeparata) were collected from TCMSP, TCM-Datebas@Taiwan and PubChen Compound database. The protein targets to the treatment of rheumatoid arthritis are found through DrugBank and TTD databases and uploaded to the String online database to build the network relationship of protein interaction. Appropriate crystal structures of protein targets were downloaded from PDB database, and molecular docking between compounds and targets was performed by using Discovery studio 4.5.0 software. A drug-compound-target visualization network was constructed by using Cytoscape 3.6.1 software to elucidate the main mechanism of GSZD against rheumatoid arthritis. Results: The results of molecular docking showed that there were 316 potential anti-arthritis active components in GSZD, acting on 26 targets, among which MAPK1, ZADH2, P38, AKR1C2, DHODH, CA2, MMP3, MMP9, RANKL, and other proteins were the main targets. Biological function and pathway analysis indicated that the mechanism of GSZD mainly involved in bone absorption (28%), histone kinase activity (20%), peptide tyrosine phosphorylation (20%), prostaglandin metabolism (12%), and other biological processes. The main pathway was osteoclast differentiation (94.12%). Conclusion: In this study, molecular docking combined with network pharmacology was used to study the pharmacodynamic material basis and molecular mechanism of GSZD in the treatment of rheumatoid arthritis from the perspective of multi-target and multi-approach, providing reference and basis for better clinical use.

ABSTRACT

Objective To establish a method for detecting the chemical compositions of “decocted first and defoamed” of Ephedra Herba by UPLC-DAD-TOF/MS coupled with HPLC-UV, so as to clarify the difference of chemical constituents among them. Methods The analysis was performed on an ACQUITY UPLC® BEH C18 column (50 mm × 2.1 mm, 1.7 μm ) by UPLC-DAD-TOF/MS with gradient elution. The mobile phase consists of methanol and 0.1% formic acid-water at a flow rate of 0.3 mL/min. The column temperature was 40 ℃. The information of compounds was acquired on positive and negative mode. Similarly, HPLC-UV was applied for measuring the content of alkaloids respectively. The C18 column was used, the mobile phase was acetonitrile-0.1% phosphoric acid (containing 0.05% triethylamine) (99 : 1) at the flow rate of 1 mL/min, the detective wavelength was set up at 210 nm, and the column temperature was 30 ℃. Results There were less content in the upper foam, and the chemical components in the lower liquid and the whole liquid were basically same. Five alkaloids and one carboxylic acid (4-hydroxy-7-methoxyl-2-quinoline carboxylic acid) was identified from all kinds of liquids. However, the content of alkaloids in the upper foam was very low, and the content of three alkaloids in the whole solution was slightly higher than that in the lower liquid. Conclusion The defoamed method may not be related to the chemical compositions of alkaloids, but it still needs further research and verification.

ABSTRACT

Decoctions of Ephedrae Herba were prepared using tap water sampled in Changping District, Beijing City(China), tap water sampled in Niigata City (Japan) and some mineral water samples sold in markets. Various dissimilarities were found between drug extracts prepared using tap water in Japan and China, and the extraction efficiency of the alkaloids with Beijing tap water was approximately 80% of that with Niigata tap water. It is suggested that these dissimilarities result from concentrations of temporally hard components, such as calcium and magnesium bicarbonate salts, in the water. In addition, when Zizyphi Fructus and Ephedrae Herba were decocted together in hard water, the state of the decoction, ephedra-alkaloid content included, was found to come close to that of single Ephedrae Herba decoctions prepared using soft water. It was suggested that Ziziphi Fructus might possibly play roles as a softening agent in decoctions prepared using hard water.
