The root of Panax notoginseng (PN) is commonly used to treat chronic liver disease with its therapeutic abilities to stop haemorrhage in the circulation, while the PN flower (PN-F) is largely unknown in the biological activities on inflammation and mechanisms of its actions. In this study, the pharmacologic effects of PN-F methanol extract on inflammation were investigated to address potential therapeutic or toxic effects in LPS-stimulated mouse macrophage cells, RAW264.7 cells. ⋯ These results indicate that PN-F extract inhibits LPS-induced inflammatory response via the blocking of NF-kappaB signaling pathway in macrophages, and demonstrated that PN-F extract possesses anti-inflammatory properties in vitro.

The present study was designed to investigate the hypoglycemic and hypolipidemic effects of the water extract (WE) and crude polysaccharides (CPs) obtained from the tuberous root of Liriope spicata (Thund.) var. prolifera Y. T. Ma, which is widely used in prescriptions of traditional Chinese medicine for the treatment of diabetes mellitus. ⋯ The results suggest that WE and CPs may have hypoglycemic and hypolipidemic potential for the type 2 diabetes and support the traditional use of the tuberous root of Liriope spicata var. prolifera as a hypoglycemic agent.
