Transcriptome changes in Polygonum multiflorum Thunb. roots induced by methyl jasmonate.
In this study, we used transcriptome profiling to investigate transcriptome changes in roots of P. multiflorum seedlings subjected to a 0.25 mmol/L-MeJA root-irrigation treatment. A total of 18 677 differentially expressed genes (DEGs) were induced by MeJA treatment, of which 4535 were up-regulated and 14 142 were down-regulated compared with controls. These DEGs were associated with 125 metabolic pathways. In addition to various common primary and secondary metabolic pathways, several secondary metabolic pathways related to components with significant pharmacological effects were enriched by MeJA, including arachidonic ac...

Discrimination and Proper Use of Polygoni Multiflori Radix, Cynanchi Wilfordii Radix, and Cynanchi Auriculati Radix in Korea: A Descriptive Review.
Authors: Lee BJ, Lee K Abstract Polygoni Multiflori Radix (PMR), Cynanchi Wilfordii Radix (CWR), and Cynanchi Auriculati Radix (CAR) are very popular herbal medicines in Traditional Korean Medicine, Traditional Chinese Medicine, and Kampo Medicine. However, the plant origins, efficacies, and traditional uses of these herbal medicines differ. In Korea, PMR is called Ha Su O (He Shou Wu in China), and CWR is called Baek Ha Su O or Baek Su O (Bai Shou Wu in China). Baek Su O refers to CWR in Korea and CAR in China. CAR has not been used as a traditional herbal medicine, and it cannot be legally used as a food...

Evidence chain-based causality identification in herb-induced liver injury: exemplification of a well-known liver-restorative herb Polygonum multiflorum
In this study, a total of 12 307 inpatients with liver dysfunction and 147 literature-reported cases of Heshouwu DILI were screened. A general algorithm indicated that only 22.5% (9/40) and 30.6% (45/147) of all hospitalization and literature case reports, respectively, demonstrate the high probability of DILI causality of Heshouwu. By contrast, 95% (19/20) of all cases prospectively investigated by pharmacognosy, phytochemistry, and metabolomic tests exhibited highly probable causality, including a patient who was previously incorrectly attributed and a case that was excluded from Heshouwu causality by pharmacognostic evi...

In vivo screening of traditional medicinal plants for neuroprotective activity against Aβ42 cytotoxicity by using Drosophila models of Alzheimer's disease.
Abstract Alzheimer's disease (AD) is the most common neurodegenerative disorder, characterized by progressive neuronal loss with amyloid β-peptide (Aβ) plaques. Despite several drugs currently used to treat AD, their beneficial effects on AD progress remains under debate. Here, we established a rapid in vivo screening system using Drosophila AD models to assess the neuroprotective activities of medicinal plants that have been used in traditional Chinese medicine. Among 23 medicinal plants tested, the extracts from five plants, Coriandrum sativum, Nardostachys jatamansi, Polygonum multiflorum (P. multiflo...

Hair Growth Promotion Activity and Its Mechanism of Polygonum multiflorum.
Authors: Li Y, Han M, Lin P, He Y, Yu J, Zhao R Abstract Polygonum multiflorum Radix (PMR) has long history in hair growth promotion and hair coloring in clinical applications. However, several crucial problems in its clinic usage and mechanisms are still unsolved or lack scientific evidences. In this research, C57BL/6J mice were used to investigate hair growth promotion activity and possible mechanism of PMR and Polygonum multiflorum Radix Preparata (PMRP). Hair growth promotion activities were investigated by hair length, hair covered skin ratio, the number of follicles, and hair color. Regulation effect...

Tetrahydroxystilbene Glucoside Improves Neurotrophic Factors Release in Cultured Astroglia.
In this study, rat primary astroglia cultures were applied to investigate TSG-mediated neurotrophic effects. The protein levels and production of glial cell-line derived neurotrophic factor (GDNF), brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in astroglia and the culture medium were determined by western blotting assay and ELISA, respectively. Results indicated that TSG increased the production of neurotrophic factors in a concentration-dependent manner. At different time points of TSG treatment, the BDNF and NGF production in the culture medium was increased 48 h after treatment, while GDNF secre...

Rhein: A Review of Pharmacological Activities.
Authors: Zhou YX, Xia W, Yue W, Peng C, Rahman K, Zhang H Abstract Rhein (4, 5-dihydroxyanthraquinone-2-carboxylic acid) is a lipophilic anthraquinone extensively found in medicinal herbs, such as Rheum palmatum L., Cassia tora L., Polygonum multiflorum Thunb., and Aloe barbadensis Miller, which have been used medicinally in China for more than 1,000 years. Its biological activities related to human health are being explored actively. Emerging evidence suggests that rhein has many pharmacological effects, including hepatoprotective, nephroprotective, anti-inflammatory, antioxidant, anticancer, and antimicr...

Neuroprotection and spatial memory enhancement of four herbal mixture extract in HT22 hippocampal cells and a mouse model of focal cerebral ischemia
Conclusions: Our results suggest that PMC-12 mainly exerted protective effects on hippocampal neurons through suppression of Ca 2+ -related ROS accumulation and regulation of signaling pathways of p38 MAPK and PI3K associated with mature BDNF expression and CREB phosphorylation and subsequently enhanced spatial memory.

A novel method to analyze hepatotoxic components in Polygonum multiflorum using ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry
This study sought to analyze the toxic components of PM using ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS), and their hepatotoxicity in L02 human liver cells. Toxicity was evaluated by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), lactate dehydrogenase (LDH) leakage, and liver enzyme secretion (aspartate aminotransferase [AST] and alanine aminotransferase [ALT]) assays. Furthermore, UPLC-Q-TOF/MS, Progenesis QI, and Makerlynx XS software analyses were used to differentiate extracts and analyze the toxic components. The order of toxicity was ...

Beneficial Effects of Polygonum multiflorum on Hippocampal Neuronal Cells and Mouse Focal Cerebral Ischemia.
Abstract Beneficial effects of the water extract of Polygonum multiflorum (WEPM) and their mechanisms were investigated in HT22 hippocampal cells and hippocampus of middle cerebral artery occlusion (MCAO) mice. In HT22 cells against glutamate-induced oxidative stress, pretreatment with WEPM resulted in significantly reduced apoptotic neuronal death. Pretreatment with WEPM resulted in the suppression of ROS accumulation in connection with cellular Ca (2+) level after exposure to glutamate. Treatment with glutamate alone led to suppressed protein level of mature brain-derived neurotrophic factor (BDNF) and p...

Effect of sample preparation on components and liver toxicity of Polygonum multiflorum
In this study, the effect of sample preparation on components and liver toxicity of different extracts from P. multiflorum were determined. Hepatoxic components were discovered based on biomembrane extraction. Comparative chemistry and toxicology between ethanol and water extracts were also performed. The results showed that ethanol extract had much stronger hepatotoxicity, the content of emodin-8-O-β-d-glucopyranoside, physcion-8-O-β-d-glucopyranoside, emodin and physcion was significantly higher in ethanol extract than in water extract, while the human hepatocytes extraction showed that 2,3,5,4′-tetrahydroxystilbene-...
