OBJECTIVETo investigate the inhibitory activities of caffeoyl glucopyranoses purified from Balanophora japonica Makino on HIV entry and their mechanism.
METHODSHIV-1 Env pseudovirus was used to evaluate the anti-HIV-1 activity of those compounds. ELISA and molecular docking were used to study the mechanism of the actions of the active compounds.
RESULTSWe used the HIV-1 Env pseudovirus to test the anti-HIV-1 activity of the six phenolic compounds (final concentration 25 microg/ml), and found that only 1,2,6-Tri-O-caffeoyl-beta-D-glucopyranose (TCGP) and 1,3-Di-O-caffeoyl-4-O-galloyl-beta-D- glucopyranose (DCGGP) could effectively inhibit the entry of HIV-1 Env pseudovirus into the target cells in a dose-dependent manner, with IC(50) values of 5.5-/+0.2 and 5.3-/+0.1 microg/ml, respectively. These two compounds could also blocked the gp41 six-helix bundle formation. Molecular docking analysis suggested that they might bind to the hydrophobic cavity of the gp41 N-trimeric coiled-coil.
CONCLUSIONTCGP and DCGGP are potent HIV-1 entry inhibitors targeting gp41 and can serve as lead compounds for developing novel anti-HIV-1 microbicides for prevention of sexual HIV-1 transmission.

OBJECTIVEMicroRNAs (miRNAs) play important roles in cell proliferation, differentiation and apoptosis. 1, 3, 4-tri-O-galloyl-6-O-caffeoyl-β-D-glucopyranose (BJA32515) is a new natural ellagitannin compound extracted from Balanophora Japonica MAKINO. The effect of BJA32515 on the expression of miRNAs in cancer cells has not yet been explored. Objective The present study was carried out to examine the changes in miRNA expression profiles in human HepG(2) hepatocarcinoma cells following BJA32515 exposure.
METHODSThe proliferation of BJA32515-exposed HepG(2) cells was assessed using a colorimetric assay (cell counting kit-8). The miRNA expression profile of the cancer cells was analyzed using a miRNA array and quantitative real-time PCR. Apoptosis was assessed by annexin V and propidium iodide staining.
RESULTSBJA32515 inhibited the cell proliferation and increased apoptosis in HepG(2) cancer cells. The exposure to BJA32515 also caused alterations in the miRNA expression profile in the cells, with 33 miRNAs upregulated and 59 down-regulated. The up-regulation of let-7a and miR-29a and the down-regulation of miR-373 and miR-197 were verified by quantitative real-time PCR. CONCLSION: BJA32515-modifed miRNA expression may mediate the antiproliferative effect of this compound in HepG(2) cancer cells.

In natural conditions, fully ripe Cynomorium songaricum seeds parasitize in Nitraria tangutorum or N. sphaerocarpa or N. sibirica or Zygophyllum xanthoxylom and Peganum harmala, were used in this study to research the morphological characteristics, embryo rate, seed viability, 1 000-grain weight, purity, water content and the seeds of different host parasitic relationship with each other. The results showed that the morphology, color and surface characteristics of the C. songaricum seeds are very similar in different hosts. According to the seed morphology can not be judged on its host. For the host to N. tangutorum or Peganum harmala or N. sibirica, we should choose the round hole screen less than 0.923 1 mm and larger than 1.066 2 mm to cleaning seeds. For the C. songaricum seeds parasitic in N. sphaerocarpa, the choice of slightly less than 0.926 1 mm and larger than 0.985 3 mm round hole screen to cleaning. For the parasitic seeds in Z. xanthoxylom, less than 0.751 3 mm and slightly larger than 1.035 3 mm round hole screen could be used. Highy significant correlation was found among the morphological indexes in C. songaricum seeds (P < 0.01). Morphological indexes and 1 000-grain weight were significantly correlated (0.01 < P < 0.05), but with the seed viability and the embryo rate were not found significant correlation. Grain weight is not related with the seed viability and the Fully mature C. songaricum seed viability is high and water content is low. The difference of the habitats and the host plants should be considered in the seed quality assessment and classification. The C. songaricum seeds on host plants are not selective, and the C. songaricum seeds from the host plants could be parasitized in other host plants.

OBJECTIVETo identify the Cynomorii Herba and its analogues species using DNA barcoding technique.
METHODTotal genomic DNA extracted from all materials using the DNA extraction kit. The internal transcribed spacer 2 (ITS2) regions were amplified using polymerase chain reaction (PCR), and purified PCR products were sequenced bi-directionally. Sequence assembly and consensus sequence generation were performed using the CodonCode Aligner 3.7.1. The Kimura 2-Parameter (K2P) distances and GC content were computed using MEGA 5. 0. Species identification analyses were conducted through the species identification system for traditional Chinese medicine and neighbor-joining (NJ) trees.
RESULTThe ITS2 sequence lengths of Cynomorii Herba were 229 bp. The average intra-specific genetic distances of Cynomorii Herba were 0.003. The average inter-specific genetic distances between Cynomorii Herba and its adulterants species were 0.760. The results showed that the minimum inter-specific divergence is larger than the maximum intra-specific divergence. The species identification system for traditional Chinese medicine and NJ trees results indicated that Cynomorii Herba and its adulterants species can be easily identification.
CONCLUSIONThe ITS2 region is an efficient barcode for identification of Cynomorii Herba, which provide a new technique to ensure clinical safety in utilization of traditional Chinese medicine.

The stem of Cynomorium songaricum is a traditional Chinese medicine reputed to have tonic effects. C. coccineum growing in northern Africa and the Mediterranean region is regarded in Arabian medical practice as the "treasure of drugs". The major constituents of Cynomorium plants have been revealed to be phenolic compounds, steroids, triterpenes, etc. Pharmacologic studies showed that the Cynomorium plants had antioxidant, immunity-improving, anti-diabetic, neuroprotective, and other bioactivities. Some chemical constituents in Cynomorium plants are unstable, implying that the chemical components of the herbal medicines produced under different conditions may be variable. This review covers the literature published until December, 2011 and describes the pharmacologic effects and secondary metabolites of Cynomorium species.

To clarify the content characteristics of the main active components and mineral elements of Cynomorium songaricum under different habitat conditions, and further explore the relationship between the quality of C. songaricum and habitats, this study took C. songaricum from 25 different habitats in China as the research object, and measured the contents of 8 main active components and 12 mineral elements separately. Diversity analysis, correlation analysis, principal component analysis and cluster analysis were carried out. The results showed that the genetic diversity of total flavonoids, ursolic acid, ether extract, potassium(K), phosphorus(P) and zinc(Zn) in C. songaricum was high. The coefficient of variation of crude polysaccharide, ether extract, gallic acid, protocatechuic aldehyde, catechin, epicatechin, calcium(Ca), sodium(Na), magnesium(Mg), sulfur(S), iron(Fe), manganese(Mn), selenium(Se) and nickel(Ni) were all over 36%, indicating that the quality of C. songaricum was significantly affected by habitats. There were strong synergistic and weak antagonistic effects among the contents of the 8 active components, and complex antagonistic and synergistic effects among the contents of the 12 mineral elements. Principal component analysis revealed that crude polysaccharide, ursolic acid, catechin, epicatechin and total flavonoids could be used as the characteristic components to evaluate the quality of C. songaricum, and Na, copper(Cu), Mn and Ni were the characteristic elements to evaluate the quality of C. songaricum. In cluster ana-lysis, the second group with the main active components as cluster center had better quality in terms of the content of active substances, and the second group with the mineral elements as cluster center had higher utilization potential in the exploitation of mineral elements. This study could provide a basis for resource evaluation and breeding of excellent varieties of C. songaricum in different habitats, and provide a reference for cultivation and identification of C. songaricum.
