A study on the immune receptors for polysaccharides from the roots of Astragalus membranaceus, a Chinese medicinal herb.
It is demonstrated that Astragalus polysaccharide fractions activates mouse B cells and macrophages, but not T cells, in terms of proliferation or cytokine production, indicating that APS activates B cells via membrane Ig in a TLR4-independent manner. Expand
Comparison of the chemical constituents of aged pu-erh tea, ripened pu-erh tea, and other teas using HPLC-DAD-ESI-MSn.
After fermentation by microorganism, the levels of catechins in ripened pu-erh tea were decreased, but the contents of gallic acid and caffeine were conversely elevated compared with aged pu- erh tea. Expand
Molecular genetic and chemical assessment of radix Angelica (Danggui) in China.
The roots of Angelica sinensis (Danggui), a traditional Chinese medicine, have been used for invigorating blood circulation for over 2000 years in China and could serve as a fingerprint for quality control ofangelica roots. Expand

Nine 2‐(2‐Phenylethyl)chromone Derivatives from the Resinous Wood of Aquilaria sinensis and Their Inhibition of LPS‐Induced NO Production in RAW 264.7 Cells
A phytochemical investigation of aquilariae lignum resinatum, the resinous wood of Aquilaria sinensis (Lour.) Gilg, led to the isolation of nine new 2-(2-phenylethyl)chromone derivatives, aquilaronesExpand
Evaluation of the anti-myocardial ischemia effect of individual and combined extracts of Panax notoginseng and Carthamus tinctorius in rats.
The findings suggest EPN combined with ECT may be therapeutically more useful for ameliorating anti-myocardial ischemia injuries than individual herbal extract, and EPN 50mg/kg plus ECT 200mg/ kg is the appropriate combination in the present research. Expand
The cytotoxic activity of ursolic acid derivatives.
Ursolic acid and 2alpha-hydroxyursolic acid isolated from apple peels were found to show growth inhibitory activity against four tumor cell lines, HL-60, BGC, Bel-7402 and Hela. StructuralExpand

One single standard substance for the determination of multiple anthraquinone derivatives in rhubarb using high-performance liquid chromatography-diode array detection.
In this study, rhubarb rhizome was selected as an example, and emodin, the easily available active component, was used as the external standard to determine directly the content of Emodin in rhubARB, and the same component as the internal standard to simultaneously determine the other six anthraquinones in Rhubarb.

Effect of the carthamins yellow from Carthamus tinctorius L. on hemorheological disorders of blood stasis in rats.
CY administration might provide the additional benefit of increasing blood fluidity by lowering blood viscosity, which can be of great value in the prevention of hemorheological disorder-associated diseases in at risk patients. Expand
