Abstract
Eucommiae Cortex is one of important traditional Chinese medicines (TCMs) used in Asia for preventing and treating osteoporosis induced by estrogen deficiency. However, the low exposure of prototype components in Eucommiae Cortex in vivo is difficult to interpret its efficacy. Under the guidance of UPLC-Q/TOF-MS, 42 metabolites including 32 lignans and 10 phenolics, 21 of which were new compounds, were isolated from rat urine and feces after oral administration of aqueous extract of E. ulmoides Oliv. by various chromatographic techniques. Their structures were determined based on extensive physicochemical analyses and spectral data. Their absolute configurations were determined by experimental and calculated ECD spectra, along with the calculated NMR with DP4 evaluation. Additionally, all isolated metabolites were evaluated for their estrogen-like activities, and there are 15 metabolites having estrogen-like effects after assessing influences in MCF-7 cells. Further, Dual Luciferase Reporter Gene Assay was used to determine their activation with estrogen receptor, M10 and M11 mixtures, M14, M19, M33, M27, M31, M38-M41 could activate ERα, and M19 and M41 could activate ERβ. These results not only clarify the pharmacological substances of Eucommiae Cortex, but also provide a basis for guiding its clinical application.

Abstract
It has been reported that Mori Folium (MF) and Eucommiae Cortex (EC) exhibit pharmacological effects in the treatment of immunosuppression. However, the mechanism of MF and EC against immunosuppression remains unclear. This study aims to explore the mechanism of action of MF and EC for the treatment of immunosuppression through network pharmacology, molecular docking, molecular dynamics simulations and animal experiments. As a result, 11 critical components, 9 hub targets, and related signaling pathways in the treatment of immunosuppression were obtained based on network pharmacology. The molecular docking suggested that 11 critical components exhibited great binding affinity to 9 hub targets of immunosuppression. The molecular dynamics simulations results showed that (-)-tabernemontanine-AR, beta-sitosterol-AR and Dehydrodieugenol-HSP90AA1 complexes are stably bound. Additionally, in the animal experiments, the treated group results compared to the control group suggest that MF and EC have a significant effect on the treatment of immunosuppression. Therefore, MF and EC treatment for immunosuppression may take effects in a multi-component, multi-target, and multi-pathway manner. The results herein may provide novel insights into the treatment of immunosuppression in humans.

Abstract
The ethyl acetate fraction of ethanol extract of Eucommiae Cortex can effectively inhibit joint inflammation and bone destruction in rats with collagen-induced arthritis(CIA) and has a potential therapeutic effect on rheumatoid arthritis. The triterpenoid(EU-Tid) and iridoid(EU-Idd) of Eucommiae Cortex are derivatives isolated from the ethyl acetate fraction of the ethanol extract of Eucommiae Cortex, and it is not clear whether they have inhibitory effects on joint inflammation and bone erosion in CIA rats. Therefore, based on the CIA model, the effects of EU-Tid, EU-Idd, and their combination(EU-TP) on arthritis in rats were observed, and the material basis of Eucommiae Cortex against arthritis was further clarified. The samples were collected two and four weeks after administration to observe the pathological changes in different stages of arthritis in CIA rats. For the rats in the model control group, with the prolongation of the disease course, the paw volume and arthritis score increased and histopathological lesions aggravated. Compared with the model control group, the drug administration groups showed reduced paw volumes and arthritis scores, and improved joint lesions and cartilage destruction. Additionally, the mRNA expression levels of tumor necrosis factor-α(TNF-α), interleukin-17(IL-17), and interleukin-23(IL-23) in the spleen were down-regulated in the drug administration groups. EU-TP and EU-Tid at concentrations of 160 and 320 μg·mL~(-1) could significantly inhibit the proliferation of human fibroblast-like synoviocytes-RA(HFLS-RA) and nitric oxide(NO) release in the supernatant of RAW264.7 cells induced by lipopolysaccharide(LPS) at the concentration range of 10-80 μg·mL~(-1) in vitro. EU-Idd had no effect on the proliferation of HFLS-RA but could reduce the NO release at concentrations of 40 and 80 μg·mL~(-1). The results indicated that the terpenoids of Eucommiae Cortex had great potential in the treatment of rheumatoid arthritis.

Abstract
OBJECTIVE In traditional Chinese medicine, the herbal pair, Radix Achyranthis Bidentatae (RAB) and Eucommiae Cortex (EC), is widely used to treat osteoporosis. Herein, we determined whether this herbal pair can be used to ameliorate glucocorticoid (GC)-induced osteoporosis (GIOP) and find its optimal dosage in zebrafish. METHODS The characteristics of the aqueous extract of RAB and EC were separately characterized using high-performance liquid chromatography. Osteoporosis was induced in 5-day post-fertilization zebrafish larvae by exposing them to 10 μmol/L dexamethasone (Dex) for 96 h. Seven combinations of different ratios of RAB and EC were co-administered. Treatment efficacy was determined by calculating zebrafish vertebral area and sum brightness, via alizarin red staining, and by detecting alkaline phosphatase (ALP) activity. Multiple regression analysis was conducted to test the optimal dosage ratio. RESULTS According to the Chinese Pharmacopoeia (2015), β-ecdysone (β-Ecd) is a major bioactive marker in RAB extract, while pinoresinol diglucoside (PDG) is the major marker in EC extract. Both of β-Ecd and PDG content values aligned with the Chinese Pharmacopoeia standards. Treatment with 10 μmol/L Dex reduced zebrafish vertebral area, sum brightness, and ALP activity, but RAB and EC attenuated these effects. Combining 50 µg/mL RAB and 50 µg/mL EC was optimal for preventing GIOP in zebrafish. Reverse transcription-quantitative polymerase chain reaction was used to evaluate the mRNA expression of osteogenesis-related genes. A treatment of 10 μmol/L Dex decreased runt-related transcription factor 2 (Runx2), osteogenic protein-1 (OP-1), bone γ-carboxyglutamic acid-containing protein (BGLAP), and β-catenin levels. This effect was counteracted by RAB and EC co-treatment (P < 0.05). Additionally, the effect of using the two herbal extracts together was better than single-herb treatments separately. These results demonstrated that RAB and EC preserve osteoblast function in the presence of GC. The best mass ratio was 1:1. CONCLUSION RAB and EC herbal pair could ameliorate GC-induced effects in zebrafish, with 1:1 as the optimal dosage ratio.

Abstract
This study aimed to explore the optimal indications and mechanism of Uncariae Ramulus cum Uncis(UR)-Eucommiae Cortex(EC) in lowering blood pressure based on network pharmacology and molecular docking. Chemical constituents were collected and screened by TCMSP database. Swiss Target Prediction platform was used to predict the related targets of the drug. OMIM, TCMIP and GeneCards databases were used to collect hypertension-related genes, and the intersections were taken to obtain potential targets for anti-hypertensive treatment of UR-EC. FunRich software was used to enrich the clinical phenotype and expression site of potential target of lowering blood pressure to analyze and predict the optimal indications of UR-EC. STRING database was used for KEGG pathway enrichment analysis, and Cytoscape 3.7.2 was used to construct the network of "composition-target-pathway". The key targets and their corresponding components in the network were analyzed and obtained, and then molecular docking was applied for preliminary verification. Twenty potential active components of UR and 24 potential active components of EC were respectively collected, and 92 anti-hypertensive potential targets of UR-EC were obtained. According to FunRich enrichment results, the optimal indication of UR-EC was pregnancy hypertension, which involved calcium signaling pathway, HIF-1 signaling pathway, neuroactive ligand receptor interaction, renin vascular tightening, VEGF signaling pathway, etc. In addition, AKT1, NOS2, ADRB2, F2, NOS3, SCN5 A, HTR2 A and JAK2 were considered as the key targets in the network. The molecular docking results showed that the screened potential active components had high binding activity with the key targets. This study preliminarily revealed that UR-EC may have therapeutic effects on pregnancy hypertension in terms of sedation, anti-hypertension, anti-inflammatory, anti-oxidation, improvement of vascular endothelial function and so on.

Abstract
Based on GC-MS metabolomics and biochemical index analysis, the mechanism of bone mass loss in osteoporosis and the evaluation of anti-osteoporosis in Eucommiae Cortex were studied. The OVX rats model was established by bilateral ovariectomized. The routine indexes such as BMC, BMD, BGP and TRAP5 b were determined. The GC-MS technique was used to analyze the metabolism profile of serum samples between the control group, model group and medicine group, and multiple statistical analysis methods including principal component analysis(PCA), partial least squares-linear discriminant analysis(PLS-LDA) and subwindow rearrangement analysis(SPA) were used to screen and identify biomarkers. Five metabolites were selected as potential biomarkers, glycine, lysine, tryptophan, docosahexaenoic acid and glucose. Except for the significant increase of tryptophan in serum of OVX rats, the other four metabolites were significantly decreased. Moreover, the five biomarkers of the medicine group had a trend of returning to rats in control group. The significantly altered metabolite levels indicated that Eucommiae Cortex may relieve the symptoms of osteoporosis by regulating amino acid metabolism and oxidative stress.

Abstract
Eucommiae Cortex is commonly used for treating various diseases in a form of the crude and salt-fired products. Generally, it is empirical to distinguish the difference between two types of Eucommiae Cortex. The metabolomics coupled with chemometrics strategy was proposed to filter the combinatorial discriminatory quality markers for precise distinction and further quality control of the crude and salt-fired Eucommiae Cortex. The metabolomics data of multiple batches of Eucommiae Cortex samples was obtained by ultra-high performance liquid chromatography coupled with mass spectrometry (UHPLC-MS). Orthogonal partial least-squares discriminant analysis was utilized to filter candidate markers for characterizing the obvious difference of the crude and salt-fired Eucommiae Cortex. The accuracy of combinatorial markers was validated by random forest and partial least squares regression. Finally, eleven combinatorial discriminatory quality markers from 67 identified compounds were rapidly screened, identified, and determined for distinguishing the difference between crude and salt-fired Eucommiae Cortex. It was demonstrated that UHPLC-MS based metabolomics with chemometrics was a powerful strategy to screen the combinatorial discriminatory quality markers for distinguishing the crude and salt-fired Eucommiae Cortex and to provide the reference for precise quality control of Eucommiae Cortex.

Abstract
Eucommiae Cortex is a classical traditional Chinese medicine, which needs to be processed by "sweating" methods. To select the suitable processing method and "sweating" processing condition for Eucommiae Cortex, in this study, the quality of Eucommiae Cortex was evaluated based on simultaneous determination of multiple bioactive constituents combined with gray relational analysis. The contents of lignans, iridoids, penylpropanoids, flavonoids, and phenols in samples were simultaneously determined using ultra-fast performance liquid chromatography coupled with triple quadrupole-linear ion trap tandem mass spectrometry. The chromatographic separation was performed on a Synergiۛ Hydro-RP 100 Å column (100 mm × 2.0 mm, 2.5 μm) at 30°C with a gradient elution of acetonitrile with 0.1% formic acid/0.1% aqueous formic acid as the mobile phase. Furthermore, gray relational analysis was performed to evaluate and sort the samples according to the contents of 14 constituents by calculating the relative correlation degree of each sample. The results demonstrated that the quality of Eucommiae Cortex "sweating" at source area was better and the better "sweating" condition was to scrape off the cork layer before "sweating" with straw covering and sun drying. The developed method could provide the foundation and support for "sweating" processing method of Eucommiae Cortex in normalization and standardization.
