Seven new triterpenoid saponins (1⁻7), together with three known ones (8⁻10), were isolated from Ilex pubescens. Elucidation of their structures was performed based on high-resolution electrospray ionisation mass spectrometry (HR-ESI-MS), infrared spectra (IR), and nuclear magnetic resonance (NMR)

The saponin fraction from the ethanolic extracts of the root of Ilex pubescens Hook. et Arn. (Ilexaceae) was found to exhibit potent anti-inflammatory effects on carrageenan-induced paw edema in rats. Two novel triterpene saponins, pubescenosides C and D (1 and 2, resp.), together with five known

The root of Ilex pubescens (Mao-Dong-Qing in Chinese, MDQ) has been commonly used for treatment of cardiovascular and inflammatory diseases in the Chinese medical system. The current studies aimed to investigate the anti-inflammatory and analgesic effects as well as the underlying mechanisms of a

3,4-dihydroxyacetophenone (DHAP), an active component isolated from leaves of Tumaodongqing (Ilex Pubescens Hook. Et Arn. Var glaber Chang), is initially used to treat cardiovascular diseases. Previously, we found it had anti-inflammatory effect on macrophages by reducing the production of TNF-alpha

A new para-quinone-type flavan, (2S)-7-methoxy-3',4'-dihydroxy-5,8-quinoflavan (1), together with three known compounds, were isolated from the leaves of Ilex centrochinensis. Their structures were elucidated by detailed spectroscopic analyses for new structure and in comparison with published data

This study was carried out to evaluate the anti-inflammatory and free radical scavenging activities of flavans from flex centrochinensis S. Y. Hu in vitro and their structure-activity relationship. LPS-stimulated RAW 264.7 macrophage was used as inflammatory model. MTT assay for cell availability,

Polyphenolics extracted from yaupon holly (Ilex vomitoria, Aquifoliaceae) (YH) leaves were investigated in human colon cells for their chemopreventive and anti-inflammatory activities. An activity-guided fractionation allowed the selection of YH flavonol-rich fraction due to its preferential

Ilex cornuta, commonly known as Chinese holly, is an evergreen shrub from the family Aquifoliaceae, and it is widely distributed in Korea and China. In folk medicine, the leaves of I. cornuta are used for treatment of several disorders, including weakness of the waist and knees, arthrodynia,

BACKGROUND Ilex asprella (Hook. et Arn.) Champ. ex Benth. (IA) is a representative medicinal plant from the South of the Five Ridges of China. Its roots (RIA) and stems (SIA) have been traditionally used for the inflammation-related diseases, such as acute and chronic pharyngitis, cough, and sore

A new triterpene glycoside ilexdunnoside A (1) and a new sulfated triterpene derivative ilexdunnoside B (2), together with five known analogues 3-7 were isolated from the roots of Ilex dunniana Levl. The structures were established by NMR spectroscopic analysis and acid hydrolysis. Results of an in

This study was to appraise the anti-inflammatory and free radical scavenging activities of ethanol extracts of Ilex ficoidea Hemsl (EIFH) and Ilex centrochinensis S.Y. Hu (EICC). Anti-inflammatory activities were evaluated using xylene-induced ear edema and the cotton pellet granuloma tests. Some

Background: Nuezhenide (NZD), an iridoid glycoside isolated from Ilex pubescens Hook. & Arn. var. kwangsiensis Hand.-Mazz. used as a traditional Chinese medicine of clearing away heat and toxic materials, displays a variety of

Seven triterpenoid saponins, named ilexsaponin I-O, along with twelve known ones, were isolated from the roots of Ilex pubescens. The structures of all compounds were elucidated by use of extensive spectroscopic methods (IR, HR-ESI-MS, and 1D and 2D NMR). Sugar residues obtained after acid

Ilex guayusa tea preparations are now commercially available as Runa tea. Little is known regarding the antioxidant and anti-inflammatory bioactivities of this tea. The I. guayusa teas had a total polyphenolic content between 54.39 and 67.23 mg GAE per g dry mass and peroxyl radical scavenging

Ilex latifolia Thunb., widely distributed in China, has been used as a functional food and drunk for a long time. This study was aimed to identify the bioactive constituents with antioxidant, antitumor, and anti-inflammatory properties. I. latifolia was extracted with 95% ethanol and then
