As one of raw materials, the rhizome of Imperata cylindrica var. major (Nees) C.E. Hubb. is used in kinds of preparations curing inflammation related diseases, while its effective substances are not yet clear. In this paper, its chemical constituents and their anti-inflammatory activities were investigated. As results, ten compounds, named as imperphenoside A (1), imperphenols B (2) and C (3), imperphenosides D–F (4–6), and imperlignanosides A–D (7–10), along with previously reported thirty-seven known ones (11–47) were obtained from it. Their structures were ascertained basing on the extensive spectroscopic methods and electronic circular dichroism data analysis. Meanwhile, compounds 4, 11, 12, 24, 27, 31, 32, 37, 43, 45, and 47 exhibited nitric oxide inhibitory effects in concentration dependent at 3, 10, and 30 μM on lipopolysaccharides induced RAW 264.7 cells. Moreover, the western blot analysis indicated that compounds 4, 11, 43, and 47 could restrain the phosphorylation of nuclear factor kappa-B kinase to down-regulate the protein expression of inflammatory cytokines such as inducible nitric oxide synthase, interleukin-6 and tumor necrosis factor-α. In conclusion, they might play the anti-inflammatory effects through regulating NF-κB signaling pathway.

Three new phenolic glycosides, carvacrol-2- O - β -D-apiofuranosyl-(1 → 6)- β -D-glucopyranoside (1), 1-methyl-3-isopropylphenol-4- O - β -D-apiofuranosyl-(1 → 6)- β -D-glucopyranoside (2), p -methoxythymol-5- O - β -D-apiofuranosyl-(1 → 6)- β -D-glucopyranoside (3), and a pair of new 8- O -4′ neolignan enantiomers (5a / 5b), together with 26 known compounds (4, 6 - 30) were isolated from the roots of Lilium dauricum. The structures of the new compounds were elucidated based on extensive spectroscopic and chemical methods, and the absolute configurations of 5a and 5b were established by electronic circular dichroism analysis. Nine compounds (1, 3, 4, 8, 9, 17, 25, 29, and 30) exhibited potent α -glucosidase inhibitory activity with IC 50values ranging from 73.4 μM to 988.2 μM. Besides, compound 19 displayed strong anticomplementary activity (CH 50: 71.6 μM).
