However, little is known about the components of MC contributing to this benefit. In the present study, cell membrane immobilized chromatography (CMC), a fast and useful method, was presented for screening potential active components of MC. HBZY-1 cells were incubated with MC (200 μg/mL) at the optimal incubation time (90 min). HPLC-DAD analysis and LC/ESI/MS/MS were performed to distinguish the active components and identify its structural ion fragments. The results showed that eight components binding to HBZY-1 cells were mudanoside B, paeoniflorin sulfonate, paeoniflorin, tetragalloyl glucose (isomeride), hexagalloyl glucose, mudanopiside A, and paeonol. In conclusion, our established CMC might be a useful method for screening potential active components in complicated traditional Chinese medicines. These components might be associated with the efficacy of MC on prevention and treatment of diabetic nephropathy.展开更多

As sources for this crude drug are always mixed with other species, many cultivars on herbal market may lead to quality instability. Multi-component quantitative analysis is an efficient method to reflect chemical profiles of herb medicine and is always taken as the main method for quality evaluation. So, the aim of this work is to develop analytical method to quantify paeonol, paeoniflorin, gallic acid, oxypaeoniflorin, benzoylpaeoniflorin and paeonolide in Cortex Moutan (CM) to evaluate the chemical qualities of CM from different species or cultivars. Besides, we also study the intestinal absorption characteristics of paeonol and paeoniflorin for further pharmacological evaluation. In the present study, all of the standard markers were performed on an Ecosil C18 (250 mm × 4.6 mm, 5 μM, Lubex Co., Guangzhou, China) with linear gradient elution of 0.2% formic acid water and acetonitrile. The proposed method was applied to analyze 50 batches of samples with acceptable linearity (R2, 0.9995 - 0.9999), precisions (RSD, 0.47% - 2.08%), repeatability (RSD, 039% - 2.63%), stability (RSD, 0.52% - 2.45%), and recovery (RSD, 0.72% - 3.03%) of the six compounds. Furthermore, the Hierarchical Cluster Analysis was applied to classify the 50 samples based on contents of the six compound markers. The results obtained from multi-component quantification of CM clearly indicated that CM originated from P. suffruticosa and P. ostii presented different chemical properties, and that samples from the two materials could be gathered into one branch, respectively, while CM sourced from cultivars of P. suffruticosa showed great variety on chemical quality. The results from Hierarchical Cluster Analysis implied that the established method could be used as a powerful tool for the quality evaluation of CM. The intestinal absorption study indicated that the intestinal absorption activities for paeoniflorin and paeonol showed an increasing absorption with time. Paeonol had lower absorption rate (6.69% - 15.93%) than that of paeoniflorin (19.0% - 30.70%). As a result, the established method is suitable for the quality evaluation of CM. The results of intestinal absorption characteristics of paeonol and paeoniflorin offer an insight for pharmacological evaluation and clinical efficacy research of CM.展开更多

Angiogenes...Metastases are the main cause of death among patients with bladder cancer, which is the second most common malignancy of the genitourinary tract and is highly prevalent in the southwestern region of Taiwan. Angiogenesis plays a critical role in tumor growth and metastasis processes and has relevance in disease recurrence, pelvic lymph node metastasis and poor prognosis. Cancer cells can produce several angiogenesis-stimulating factors involved in vascular growth, including vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and inflammatory cytokines such as interleukin (IL)-8. Common chemotherapeutic drugs for intravesical instillations usually cause major side effects, including urinary frequency, urinary urgency, cystitis, and hematuria. In order to identify a less cytotoxic therapeutic agent that can inhibit tumor cell proliferation, we examined the traditional Chinese herbal medicine Cortex Moutan—reported to have antibacterial, antiviral, anti-inflammatory, antithrombotic, and antitumor properties—for its effects on bladder cancer cell proliferation and expression of angiogenic factors. Our results revealed that Cortex Moutan exhibited high selectivity in inhibiting the growth of bladder cancer cells and also reduced the expression of angiogenesis-stimulating factors in those cells. Thus, we suggest that Cortex Moutan might be used as a cancer therapy drug for bladder’s intravesical chemotherapy in the future.展开更多
