Three new coumarin derivatives, 8-formylalloxanthoxyletin (1), avicennone (2), and (Z)-avicennone (3), have been isolated from the stem bark of Zanthoxylum avicennae (Z. avicennae), together with 15 known compounds (4-18). The structures of these new compounds were determined through spectroscopic

OBJECTIVE To provide the scientific evidence for expansion of medicinal parts of Zanthoxylum nitidum by comparing the effects of anti-contusion injury, analgesia and anti-inflammation of its root and stem. METHODS The pharmacological effects between root and stem of Zanthoxylum nitidum were compared

In the effort to identify natural products that regulate immunity and inflammation, we found that nitidine chloride (NC), an alkaloid from herb Zanthoxylum nitidum, enhanced IL-10 production in lipopolysaccharide (LPS)-stimulated myeloid cells. While NC was shown to be capable of inhibiting

BACKGROUND Maqian (Zanthoxylum myriacanthum var. pubescens Huang) is widely consumed as an indigenous remedy for digestive disorders, detoxification, detumescence and analgesia by the ethnic groups in Xishuangbanna, SW China. A related species, Huajiao (Zanthoxylum schinifolium Sieb. et Zucc.), has

Bone morphogenetic protein-2 (BMP-2) is commonly applied in spinal surgery to augment spinal fusion. Nevertheless, its pro-inflammatory potential could induce dangerous side effects such as vascular hyper-permeability, posing the need for manners against this condition. This study aims to

The antiphoto aging property of Zanthoxylum rhetsa obtained from Pangkor Island, Malaysia, was evaluated. Solvent fractions of different polarity obtained from the methanolic extract of the bark material were initially tested for anticollagenase and antielastase activities. The ethyl acetate

Chemical investigations on the fruits of Zanthoxylum armatum Roxb. (Rutaceae) led to the isolation of two new constituents characterised as 2α-methyl-2β-ethylene-3β-isopropyl-cyclohexan-1β, 3α-diol (1) and phenol-O-β-D-arabinopyranosyl-4'-(3″, 7″, 11″, 15″-tetramethyl)-hexadecan-1″-oate (2) along

We have evaluated the anti-inflammatory and analgesic properties of the leaves (LCE) and stem bark (BCE) crude extracts of Zanthoxylum riedelianum (Rutaceae). Different fractions of the stem bark extract (hexane, BCEH; dichloromethane, BCED; ethyl acetate, BCEE; and lyophilized aqueous residual,

We reported that ailanthoidol, a neolignan from Zanthoxylum ailanthoides and Salvia miltiorrhiza Bunge, inhibited inflammatory reactions by macrophages and protected mice from endotoxin shock. We examined the anti-inflammatory activity of six synthetic ailanthoidol derivatives (compounds 1-6). Among

The biological properties of ailanthoidol, a neolignan from Zanthoxylum ailanthoides or Salvia miltiorrhiza Bunge, which is used in Chinese traditional herbal medicine, have not been evaluated. Here, we report that ailanthoidol inhibits inflammatory reactions in macrophages and protects mice from

OBJECTIVE This study was carried out to investigate the anti-inflammatory potentials of 24 kDa glycoprotein isolated from Zanthoxylum piperitum DC fruit (ZPDC glycoprotein) in lipopolysaccharide (LPS)-stimulated murine macrophage cell line (RAW 264.7 cells). METHODS RAW 264.7 cells were treated with

In this study, 44 compounds in the petroleum ether extract of Maqian (Zanthoxylum myriacanthum var. pubescens) bark, a traditional Dai herbal medicine, were identified by GC-MS. Major components included 3(2H)-benzofuranone, asarinin and (dimethoxymethyl)-3-methoxy-benzene. A total of 18 compounds

The purpose of this study is to investigate the anti-inflammatory potentials of a 24-kDa glycoprotein isolated from Zanthoxylum piperitum DC fruit (ZPDC glycoprotein) in dextran sulfate sodium (DSS)-stimulated ICR mouse colitis. ZPDC glycoprotein was administered to mice at 10 and 20 mg/kg for 7

Inflammation is a very common and important basic pathological process. There is still a great need for the isolation of effective anti-inflammatory agents from plants. In this paper, five new isobutylamides, zanthoxylumamides E-I (1-5), and four known isobutylamides (6-9) were isolated from

Seven benzophenanthridine alkaloids, 1-7, were isolated from the roots of Zanthoxylum nitidum. Among them, two novel alkaloids, named (R)-8-[(R)-1-hydroxyethyl]dihydrochelerythrine (1) and 8-methoxynorchelerythrine (2), were structurally identified as new compounds on the basis of the spectroscopic
