litsea pierrei/抗炎症薬

BACKGROUND The study was conducted to evaluate the in vitro thrombolytic activity, and in vivo analgesic, anti-inflammatory and antipyretic potentials of different hydrocarbon soluble extracts of Litsea glutinosa leaves for the first time widely used in the folkloric treatments in Bangladesh. This

Five new lactones, litsenolide F1 (1), lisealactone H1 (10), lisealactone H2 (11), akolactone D (13), and akolactone E (14), along with thirteen known compounds were isolated from the pericarps of Litsea japonica (Thunb.) Jussieu. Their chemical structures were elucidated by extensive spectroscopic

Fruits of the Litsea family of trees and shrubs contain biologically active compounds, some of which have been used as natural nutrients and flavoring agents in food. In this study, we identified novel anti-nociceptive effects of the 30% ethanol extract, the CH(2)Cl(2) fraction and the associated

OBJECTIVE To evaluate the application of spent Pleurotus ostreatus substrates, enriched or not with medicinal herbs, as a source of anti-inflammatory compounds. METHODS P. ostreatus was cultivated on five different substrates: Barley straw (BS) and BS combined 80:20 with medicinal herbs (Chenopodium

Two new dihydrostilbenoid glycosides, named 5-(2-phenylethyl)-3-hydroxyphenol-1-O-beta-D-glucopyranoside (1) and 6-(2-phenylethyl)-2,4-dihydroxy benzoic acid-2-O-beta-D-glucopyranoside (2), together with two known compounds, were isolated from the leaves of Litsea coreana Levl.. Their structures

The anti-inflammatory effects of boldine and reticuline isolated from Litsea cubeba were evaluated by using xylene-induced ear edema and carrageenan-induced paw edema in mice and rats. Our results demonstrated that intragastric administration with boldine and reticuline significantly mitigated ear

Context Litsea cubeba (Lour.) Pers. (Lauraceae) has long been used as a folk remedy in Traditional Chinese Medicine (TCM) for the treatment of rheumatic diseases. Previous studies from our laboratory indicated that L. cubeba extract showed anti-arthritic activity in rats. Objective To study L.

We examined the antiosteoarthritic effect of the n-hexane extract of Litsea japonica fruit flesh (LJF-HE) in a rat model of monosodium-iodoacetate- (MIA-) induced osteoarthritis. LJF-HE significantly reduced the difference in weight-bearing capabilities of the hind paws between healthy and

Periodontal disease, a chronic disease caused by bacterial infection, eventually progresses to severe inflammation and bone loss. Regulating excessive inflammation of inflamed periodontal tissues is critical in treating periodontal diseases. The periodontal ligament (PDL) is primarily a connective

A phytochemical investigation on the roots and stems of Litsea cubeba led to the isolation of seven isoquinolone alkaloids. By spectroscopic analysis and comparison of their 1H and 13C-NMR data with those in literatures, these alkaloids were identified as (+)-norboldine (1), (+)-boldine (2),

Nitric oxide (NO) produced by inducible nitric oxide synthase (iNOS) has played a crucial role in various pathophysiological processes including inflammation and carcinogenesis. Therefore, the inhibitors of NO synthesis or iNOS gene expression have been considered as potential anti-inflammatory and

Two new flavanocoumarins, 1 and 2, together with phyllocoumarin (3) and epiphyllocoumarin (4), were isolated from the leaves of Litsea coreana LEVL. in Anhui Province, China. The structures of 1-4 were elucidated by spectroscopic methods. Biological tests revealed that 1-4 exhibited moderate

The root and rhizome of Litsea cubeba (Lour) Pers., named 'Dou-chi-jiang' in Chinese, has been traditionally used for treatment of cardiovascular and cerebrovascular diseases, rheumatic arthralgia, and other diseases in China. Aporphine alkaloids are its characteristic ingredients and responsible

Litsea coreana Levl., a traditional Chinese medicine, has long been used for its diverse benefits such as detoxification and detumescence. Total flavonoids from Litsea coreana Levl. (TFLC) are the effective fraction of L. coreana. This study was designed to investigate the anti-inflammatory effects

A bioassay-guided fractionation of the roots and stems of Litsea cubeba led to the isolation of 14 constituents, including three new compounds, cubebanone (1), N-cis-3,4-methylenedioxycinnamoyl-3-methoxytyramine (2), and 9,9'-O-di-(E)-feruloyl-(+)-secoisolariciresinol (3), together with 11 known
