Three new thionic compounds, ()-2-(2-carboxyl-2-hydroxyethylthio)-ferulic acid (), ()-2-methoxy-4-(3-(methylsulfonyl)prop-1-en-1-yl)phenol (), and thiosenkyunolide C (), together with two new aromatic glycosides ( and ) were isolated from the rhizome of Hort. Two known compounds ( and ) were also obtained. Their structures were elucidated based on extensive spectroscopic data (UV, IR, 1D and 2D NMR, and HR-ESI-MS). Furthermore the absolute configurations were established by comparison of their calculated and experimental circular dichroism spectra and by a dimolybdenum tetraacetate [Mo(AcO)]-induced circular dichroism procedure. All compounds were evaluated against lipopolysaccharide (LPS)-induced NO production in BV2 cells, and compounds and showed strong inhibitory activities with IC values of 2.03 and 3.09 µmol/L, respectively (positive control curcumin, IC = 6.17 µmol/L). In addition, compound showed weak proteintyrosine phosphatase-1B (PTP1B) inhibitory activity.

Two new compounds, named lyciumlignan D () and lyciumphenyl propanoid A (), along with seven known compounds, were isolated from the root bark of. Their structures were elucidated using spectroscopic data (UV, IR, HR-ESI-MS, 1D and 2D NMR, CD), as well as by comparison with those of the literature. Compounds-were isolated from this genus for the first time. In theassay, compounds,, andexhibited stronger anti-inflammatory effects than the positive control curcumin at a concentration of 10 μmol/L.

Thirteen compounds were isolated from the flowers of Chrysanthemum indicum by chromatographic techniques. Their structures were elucidated by spectroscopic methods as acacetin-7-0-beta-D-glucopyranoside (1), luteolin (2), luteolin-7-O-beta-D-glucopyranoside (3), acaciin (4), acacetin 7-0-(6"-0-alpha-L-rhamnopyranosyl)-beta-sophoroside (5), 3-0-caffeoylquinic acid (6), syringaresinol 0-beta-D-glucopyranoside (7), 5,7-dihydroxychromone (8), uracil (9), p-hydroxybenzoic acid (10), 4-0-beta-D-glucopyranosyloxybenzoic acid (11), boscialin (12), blumenol A (13). Compounds 5, 7, 8, 11-13 were isolated from C. indicum for the first time.
