gnetum latifolium/抗炎症薬

One new stilbenolignan, gnetucleistol F (1), and four known stilbenolignans, gnetofuran A (2), lehmbachol D (3), gnetifolin F (4) and gnetumontanin C (5) were isolated from the lianas of Gnetum cleistostachyum C. Y. CHENG (Gnetaceae). Their structures and relative configurations were determined by

The first isorhapontigenin tetramer, gnetuhainin R (1) and a novel dimeric stilbene, gnetuhainin S (2) were isolated from the lianas of Gnetum hainanense. Their structures were elucidated on the basis of spectroscopic and chemical evidence, especially 2D NMR analysis. The structure of 2 was further

Oligostilbenes are polyphenol oligomers derived from resveratrol and are commonly produced by members of the Gnetaceae family, and many researchers have focused on their anti-inflammatory activities. The EtOAc fraction of a Gnetum latifolium extract showed inhibitory activity against

Three new stilbene trimers, gnetuhainins M-O (1-3), were isolated from the lianas of Gnetum hainanense. Their structures and relative configurations were determined by spectroscopic evidence, especially on 2D NMR analysis. The anti-inflammatory activity has been tested for the isolated compounds.

A new dimeric stilbene, gnetifolin P (1), was isolated from the lianas of Gnetum parvifolium, together with seven known compounds 2-8. The structure of compound 1 was determined by extensive NMR and HRESIMS data analyses, and quantum chemical calculations. All the compounds were evaluated for their

BACKGROUND Aconitum has been used as local and traditional medicines in many asian regions for the treatment of various diseases such as collapse, syncope, painful joints, oedema, bronchial asthma et al. Higenamine, a plant-based alkaloid, was initially isolated from Aconitum and identified as the

A new resveratrol trimer derivative, named as gnetubrunol A (1), together with five known stilbene derivatives, shegansu B (2), resveratrol (3), isorhapontigenin (4), gnetifolin E (5), and isorhapontigenin-11-O-β-d-glucopyranoside (6) were isolated from the lianas of Gnetum brunonianum Griff. Their

Studies were undertaken to evaluate the bioavailability in rats and content analysis of gnetol in Gnetum gnemon products reported to contain gnetol and to examine the pharmacological properties of gnetol in in vitro models including anti-inflammatory/analgesic, antidiabetic, anti-adipogenesis, and

Microglia-driven inflammatory processes are thought to play an important role in ageing and several neurological disorders. Since consumption of a diet rich in polyphenols has been associated with anti-inflammatory and neuroprotective effects, we studied the effects of twenty-five stilbenoids
