Astilbin from Roxb. Attenuates Inflammatory Responses in Complete Freund's Adjuvant-Induced Arthritis Rats.

Astilbin, a flavonoid compound, was isolated from the rhizome of Roxb. (with red cross-section) grown in Guizhou Province, China. We accessed its effect and potential mechanism on attenuation of the inflammatory response in CFA-induced AA rats.

[UPLC and HPLC analysis on contents of astilbin and engeletin in dong medicine "sunl gaems" of Guizhou origin by QAMS].

This study aimed to simultaneously determine the contents of astilbin and engeletin in dong medicine "sunl gaems" of Guizhou origin by quantitative analysis of multi-components by single marker (QAMS), with astilbin as the internal standard substance. On UPLC and HPLC chromatograms, different models of instruments were used to investigate relative correction factors (RCF), in order to discuss the interoperability of RCFs established in different chromatographic systems. The engeletin content was calculated based on the established RCFs and compared by the one point external standard method and the external standard working curve method, in order to verify the accuracy of QAMS.

[Study on scavenging activity to DPPH free radical of different polarity components in Guizhou Miao medicine "bod zangd dak"].

The paper is aimed to search more natural plant antioxidants and further research and develop new medicinal plant resources in Guizhou. The Guizhou special miao medicine "bod zangd dak" was extracted with 60% ethanol. The antioxidant activity of the different polarity components separated from the extract was tested by DPPH method with ascorbic acid as positive control.

[Comparison of anti-inflammatory effect and analysis of astilbin red and white transverse section Smilax glabra in 28 collection sites].

Objective: Astilbin in 28 Smilax glabra (red and white cross-section) from different sources was determined by HPLC. Pharmacodynamics and component of S. glabra was investigated through inflammation experiment (penetration type).
