polysaccharide alleviates Parkinson's disease inhibiting apoptotic and inflammatory signaling pathways and modulating the gut microbiota.

Parkinson's disease (PD) is a common, chronic, and progressive degenerative disease of the central nervous system for which there is no effective treatment. is a well-known food and medicine homologous resource with neuroprotective potential. polysaccharide (GEP), which is a highly active and safe component in , is an important ingredient in the development of functional products.

[Quality evaluation and multi-spectral identification of origin herbs of Lonicerae Japonicae Flos based on grey correlation-TOPSIS method].

The grey correlation-TOPSIS method was used to evaluate the quality of the origin herbs of Lonicerae Japonicae Flos, and the Fourier transform near-infrared(NIR) and mid-infrared(MIR) spectroscopy was applied to establish the identification model of origin herbs of Lonicerae Japonicae Flos by combining chemometrics and spectral fusion strategies. The content of neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, caffeic acid, secoxyloganin, isoquercitrin, isochlorogenic acid B, isochlorogenic acid A, and isochlorogenic acid C in six origin herbs of Lonicerae Japonicae Flos was determined by high-performance liquid chromatography(HPLC), and their quality was evaluated by the grey correlation-TOPSIS method. The Fourier transform NIR and MIR spectra of six origin herbs of Lonicerae Japonicae Flos(Lonicera japonica, L.

Effects of Native Arbuscular Mycorrhizae Isolated on Root Biomass and Secondary Metabolites of Bge.

Arbuscular mycorrhiza fungi (AMFs) are a group of soil-dwelling fungi that form symbiotic associations with plants, to mediate the secondary metabolism and production of active ingredients in aromatic and medicinal plants. Currently, there is little research on Bge. inoculation with native AMFs and the concomitant effects on growth and secondary metabolites.

[Screening and Research Cyathula officinalis in Cold Hardy Physiological Characteristics].

Objective: To explore the mechanism in cold-resistant of Cyathula officinalis seedlings,in order to provide a theoretical basis for variety breeding and resistance cultivation of Cyathula officinalis.

Methods: Collected the materials in main producing areas of Cyathula officinalis,and the Cyathula officinalis growing into seedling with five pairs of leaves were used to research. The seeds were deal with low temperature stress,and the seedlings of morphological and physiological indicators of Cyathula officinalis were measured,membership function method and low temperature variation index were used to screen and evaluate the cold-tolerance of the Cyathula officinalis.

[Anti-dementia effect of Tongluo Xingnao effervescent tablet based on urinary metabonomics].

Tongluo Xingnao effervescent tablet (TLXNET) is a patented prescription, which comes from modified Xionggui decoction and can improve cognitive function. However, its effect on the urine metabolites and anti-dementia mechanism in the dementia model rats induced by hippocampal injection with Aβ25-35 remains unclear. The experiment focused on the changes in trajectory and inter-relationship among the urinary metabolite of rats in the blank group, Aβ25-35 hippocampal injection dementia model group and the TLXNET intervention group, in order to determine theirs characteristic metabolic markers and explain the anti-dementia effect of TLX-NET base on the change of metabolic trajectory of these bio-markers.

[Effect of tongluo xingnao effervescent tablet on learning and memory of AD rats and expression of insulin-degrading enzyme in hippocampus].

Objective: To study the effect of Tongluo Xingnao effervescent tablet on learning and memory of dementia rats induced by injection of Abeta25-35 in hippocampus and expression of insulin-degrading enzyme in hippocampus, in order to provide basis for preventing and treating senile dementia.

Method: The dementia rat model was established by injecting Abeta25-35 in hippocampus. The rats were divided into the model control group, the Aricept (1.

[Diversity study of arbuscular mycorrhizal fungi of Coptis deltoidea].

Objective: To investigate the resources and distribution of Arbuscular Mycorrhizal Fungi (AMF) in rhizosphere of Coptis deltoidea.

Methods: The colonization situation of AMF of Coptis deltoidea were detected by acid fuchsin staining and then calculated the colonization rate. AMF fungal spores were obtained by Wet-screening method and then classified and identified by their morphological characteristics and histochemical staining method.

[HPLC fingerprint of Rhizoma Polygoni Cuspidati].

Objective: To establish the HPLC fingerprint of Rhizoma Polygoni Cuspidati (Polygonum cuspidatum).

Method: The HPLC separation was carried with Diamonsil C18 column and eluted with a gradient from methanol and 0.1% phosphoric acid, the detection wavelength was at 230 nm and recording 70 min.
