Chemical fractionation of the n-BuOH partition, which was generated from the EtOH extract of the flower buds of Tussilago farfara, afforded a series of polar constituents including four new sesquiterpenoids (1-4), one new sesquiterpenoid glucoside (5) and one known analogue (6) of the eudesmane type, as well as five known quinic acid derivatives (7-11). Structures of the new compounds were unambiguously characterized by detailed spectroscopic analyses, with their absolute configurations being established by X-ray crystallography, electronic circular dichroism (ECD) calculation and induced ECD experiments. The inhibitory effect of all the isolates against LPS-induced NO production in murine RAW264.7 macrophages was evaluated, with isochlorogenic acid A (7) showing significant inhibitory activity.

Gastrodin(GAS) and p-hydroxybenzyl alcohol(HBA) are extracts of dried tubers of Gastrodia elata, which is the material basis for its efficacy and belongs to phenolic compounds. Modern pharmacology studies have shown that they have significant effects on central nervous system diseases, such as insomnia, convulsions, depression, ischemic stroke, anxiety, and cognitive impairment, and these diseases are closely related to neurotransmitters and cytokines. This paper described various mechanisms of GAS and HBA monomer components on the central nervous system. They alleviate hippocampal neuronal toxicity mainly by regulating a variety of neurotransmitters, such as acetylcholine, glutamic acid(GLU), γ-aminobutyric acid(GABA), serotonin(5-HT), dopamine(DA), norepinephrine(NE), 5-indoleacetic acid(5-HIAA), high vanillic acid(HVA) and dihydroxyphenylacetic acid(DOPAC), pro-inflammatory cell growth factors, such as IL-1β, IL-6 and TNF-α and relevant receptor functions, and exert neuropharmacological effects by effectively increasing mRNA expressions of brain neurotrophic factors, such as BDNF and GDNF, and further inhibiting the apoptosis of damaged neurons. This paper summarized various mechanisms on the central nervous system, which provides a scientific basis for the further research of the neuropharmacological mechanism of GAS and HBA and the development of new drugs and functional food.

Two new lignan glucosides, tinsinlignans A and B (1 and 2), two new oxyneolignans, tinsinlignans C and D (3 and 4), along with one known analogue (5), were isolated from the stems of Tinospora sinensis. The structures of the new compounds were elucidated based on analysis of spectroscopic data, and the absolute configuration of 1 was determined through electronic circular dichroism (ECD) calculation based on the time-dependent density functional theory (TD-DFT). Compounds 1-4 were evaluated for their inhibitory effects on nitric oxide (NO) production induced by lipopolysaccharide (LPS) in murine RAW264.7 macrophage cells and compounds 1 and 2 exhibited moderate inhibitory activities with IC

Correlated literatures of the liver injury induced by glucoside tripterygium total (GTT) and of its synergism and toxicity reducing effects were retrieved to study the correlation between the dosage, the time point of GTT and the liver injury. The monomer or active ingredients of animals and plants with the hepatoprotective effect were included. The mechanisms of action between GTT and these drugs were analyzed. The mechanism for GTT induced liver injury and its synergism and toxicity reducing mechanisms, as well as the preventive measures were discussed, thus providing evidence-based basis for safe clinical application of GTT.

The conversion of exogenous p-hydroxybenzaldehyde to p-hydroxy-methyl-phenol-beta-D-glucoside (gastrodin) was studied by using cell suspension culture of Datura tatula L. The chemical structure of this synthesized gastrodin was identified based on the spectral analysis and chemical evidence. The conversion procedure of p-hydroxybenzaldehyde into gastrodin by D. tatula L. cell suspension cultures was established. The synthesized gastrodin (II) was isolated from the ferment liquor and identified by spectral analysis. At the same time, the p-hydroxybenzyl alcohol (I) converted through biotransformation of p-hydroxybenzaldehyde by cell suspension cultures of D. tatula L. was also isolated and identified. The efficiency of glucosylation of p-hydroxybenzaldehyde was remarkably enhanced by adding salicylic acid (0.1 mg/L) and keeping the lower pressure (0.001MPa) in 25L airlift loop bioreactor. The biotransformation of exogenous p-hydroxybenzaldehyde to gastrodin by cell suspension culture of D. tatula L. is a promising approach.
