[Study on improvement and mechanism of tableting properties of porous Fagopyri Dibotryis Rhizoma powders].

At present, there are many difficulties in the development and production of traditional Chinese medicine(TCM) tablets. This work aimed to explore the feasibility of improving dissolution difficulty and large dosage of TCM tablets by co-spray drying TCM extract with a small amount of pore-foaming agent ammonium bicarbonate. A series of porous Fagopyri Dibotryis Rhizoma powders were prepared by co-spray drying Fagopyri Dibotryis Rhizoma with different amounts of ammonium bicarbonate, and their powder pro-perties and tablet properties were comparatively investigated.

Metabolic profiling investigation of Fritillaria thunbergii Miq. by gas chromatography-mass spectrometry.

Thunberg fritillary bulb (the dry bulbs of Fritillaria thunbergii Miq.), a traditional Chinese Medicine, is widely applied as an expectorant and antitussive. In this investigation, the primary metabolites of bulbs, flowers, leaves, and stems of F.

Systematic Understanding of the Mechanism of Salvianolic Acid A via Computational Target Fishing.

Salvianolic acid A (SAA) is one of the most abundant water-soluble and potent anti-oxidative compounds isolated from Danshen, a traditional Chinese medicine. A systematic overview of its mechanism of action is yet to be performed. In the present study, the druggability of SAA was measured using the TCMSP server, and potential targets of SAA were identified by PharmMapper and DRAR-CPI.

[Identification of alkaloids and flavonoids in all parts of Fritillaria thunbergii using LC-LTQ-Orbitrap MSn].

Alkaloids and flavonoids in flowers, flower buds, stems, leaves, and bulbs of Fritillaria thunbergii were identified by LC-LTQ-Orbitrap MSn.Alkaloids were identified by ACQUITY UPLC BEH C₁₈（2.1 mm×50 mm, 1.

Photochemical degradation performance of quinoline aqueous solution in the presence of hydrogen peroxide.

Photochemical degradation performance of quinoline aqueous solution in the presence of H2O2 was carried out, and some intermediates produced during quinoline degradation were also identified tentatively. The experimental results showed that the advanced oxidation of quinoline by UV/H2O2 process accorded well with the pseudo first order kinetics, and the dependence of concentrations of H2O2 and quinoline, and pH value on the photodegradation kinetics has been investigated in detail. It is found that the concentrations of hydrogen peroxide and quinoline have opposite effect on photodegradation kinetics.
