The Weimusi tungsten-manganese polymetallic deposit in Song County, tectonically located at the junction of Xiong'er Mountain uplift and Songxian fault basin in the eastern section of Huaxiong platform margin depression, is a new type of W-Mn polymetallic deposit discovered in western Henan Province in recent years. The orebodies are occurred in the NW-trending fracture zone on the margin of fault basin, controlled by formation lithology, structure and magmatic hydrothermal fluid. Three W-Mn polymetallic orebodies are delineated, with paragenesis of W, Mn, Pb and Fe. The genesis of deposit is closely related to postmagmatic hydrothermal filling and metasomatism, belonging to the postmagmatic hydrothermal W-Mn polymetallic deposit. [ABSTRACT FROM AUTHOR]

The chemical composition of the aqueous part of the extract from Lindera aggregata was studied, which was separated and purified by the macroporous resin column chromatography, MCI medium pressure column chromatography, semi-preparative high-performance liquid phase and other methods. The structures of the compounds were identified according to physical and chemical properties and spectroscopic data. Thirteen compounds were isolated and identified from the aqueous extracts, which were identified as(1S,3R,5R,6R,8S,10S)-epi-lindenanolide H(1), tachioside(2), lindenanolide H(3), leonuriside A(4), 3,4-dihydroxyphenyl ethyl β-D-glucopyranoside(5), 3,4,5-trimethoxyphenol-1-O-6-α-L-rhamnose-(1→6)-O-β-D-glucoside(6), 5-hydroxymethylfurfural(7),(+)-lyoniresin-4-yl-β-D-glucopyranoside(8), lyoniside(9), norboldine(10), norisopordine(11), boldine(12), reticuline(13). Among them, compound 1 was a new one, and compounds 2, 5, 6, 8, 9 were obtained from L. aggregata for the first time. The inflammatory model was induced by lipopolysaccharide(LPS) in the RAW264.7 cells. The results showed that compounds 1, 8, 10 and 12 had significant anti-inflammatory activity.
