[Study on water-soluble chemical constituents of Taraxacum mongolicum]
Objective:
To study the water-soluble chemical constituents of Taraxacum mongolicum.
Methods:
The chemical constituents were isolated and purified by means of several chromatographic techniques and their structures were elucidated by spectroscopic methods.
Results:
Nine compounds were isolated and identified as trans-p-coumaryl alcohol(1), trans-p-coumaryl aldehyde(2),p- hydroxybenzoate (3) , p-hydroxyphenyl-propionic acid (4) , 4-hydroxy-2, 6-dimethoxyphenol-1 -O-β-D-glucopyranoside (5) , protocate- chuic aldehyde(6) ,rutin(7) ,quercetin(8) ,kaempferal-3-O-α-L-rhamnopyranosyl-( 1-6) -β-D-glucopyranoside(9).
Conclusion:
Com pounds 1-6 are isolated from this plant for the first time.

Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules,...
Spasmolytic Agents: Chemical Classification
A major class of centrally acting spasmolytics is the α2-agonist, such as tizanidine. These drugs bind to α2-adrenoceptors, inhibiting the release of the excitatory neurotransmitter glutamate. They also...
