aquilaria/inflammation

The tree Aquilaria malaccensis is a valuable source of agarwood, which is used in herbal medicinal preparations. Phytochemical research on A. malaccensis seeds has led to the isolation of four new phorbol esters (1-4), two known phorbol esters (5, isolated from Nature for the first time, and 6), and

Four new benzophenone glycosides named as aquilaside A-D (1-4) along with five known compounds (5-9) were isolated from the methanol extract of the flower buds of Aquilaria sinensis. Their structures were elucidated on the basis of 1D and 2D NMR and mass spectroscopic analyses. All purified

OBJECTIVE The analgesic and anti-inflammatory activities of the ethanol extract of Aquilaria sinensis (Lour.) Gilg. Leaves were observed in various experimental models related to nociception and inflammation, so as to provide some evidence for its traditional use. METHODS Acetic acid-induced

Four new 5,6,7,8-tetrahydro-2-(2-phenylethyl)chromones, aqulisinone A (1), (5S, 6R,7S,8S)-8-chloro-5,6,7-trihydroxy-2-[2-(4'-methoxyphenylethyl)]-5,6,7,8-tetrahydrochromone (2), (5S,6R,7S,8S)-8-chloro-5,6,7-trihydroxy-2-(2-phenylethyl)-5,6,7,8-tetrahydrochromone (3),

Two new benzophenone glycosides, aquilarisides A (1) and B (2), together with six known analogues (3-8) were isolated from the pericarps of Aquilaria yunnanensis S. C. Huang. Their structures were elucidated on the basis of 1D and 2D NMR and mass spectroscopic analyses, and the absolute

Sixteen new 2-(2-phenylethyl)chromone dimers, including four pairs of enantiomers (1a/1b, 3a/3b, 6a/6b, and 8a/8b), along with eight optically pure analogues (2, 4, 5, 7, and 9-12) were isolated from the resinous wood of Aquilaria sinensis. Their structures were determined by extensive spectroscopic

The present study is to investigate the chemical constituents and anti-inflammation of agarwood produced via whole-tree agarwood-inducing technique( Agar-Wit) from Aquilaria sinensis by column chromatographic technique and semi-preparation HPLC.Eleven sesquiterpenes were isolated from the agarwood

Flavonoids, widely present in medicinal plants and fruits, are known to exhibit multiple pharmacological activities. In this study, we isolated a flavonoid compound, pilloin, from Aquilaria sinensis and investigated its anti-inflammatory activity in bacterial lipopolysaccharide-induced RAW

In Thailand, the leaves of Aquilaria crassna have been used traditionally for the treatments of various disorders, but without any scientific analysis. In this study, the antipyretic, analgesic, anti-inflammatory and anti-oxidative properties of A. crassna leaves extract were investigated at a wide

Fifteen previously undescribed 2-(2-phenylethyl)chromone dimers, along with two known analogues were isolated from Chinese agarwood (Aquilaria sinensis) by a LC-MS-guided fractionation procedure. Their structures were elucidated on the basis of spectroscopic and spectrometric data (1D and 2D NMR,

BACKGROUND Aquilaria spp. (agarwood) has been a part of Ayurvedic and Traditional Chinese Medicine for centuries. Agarwood has also been used as a traditional medicine in Southeast Asian countries, Bangladesh and Tibet. Its common uses include the treatment of joint pain, inflammatory-related

In the current study, two new flavones, 4'-O-geranyltricin (1) and 3'-O-geranylpolloin (2), and a new 2-(2-phenylethyl)-4H-chromen-4-one derivative, 7-hydroxyl-6-methoxy-2-(2-phenylethyl)chromone (3), have been isolated from the stem barks of A. sinensis, together with 21 known compounds 4-24. The

The resinous wood of Aquilaria sinensis, known as agarwood (Chen Xiang in Chinese), is traditionally used for the treatment of abdominal pain, vomiting, circulatory disorders, and dyspnea. Four new 2-(2-phenylethyl)-4H-chromen-4-one derivatives, namely

Four new 2-(2-phenylethyl)-4H-chromen-4-one derivatives, 6-hydroxy-5-methoxy-2-[2-(4'-methoxyphenyl)ethyl]chromone (1: ), 6,7-dimethoxy-2-[2-(2'-hydroxyphenyl)ethyl]chromone (2: ), 5-hydroxy-6-methoxy-2-[2-(3'-methoxyphenyl)ethyl]-chromone (3: ), and

Aquilaria agallocha Roxb. family, Thymelaeaceae, is an evergreen plant of South-East Asia, commonly described as aloe wood or agarwood. Traditionally, the bark, root and heartwood are used for their medicinal properties as a folk medicine for hundreds of years. Chemical analyses revealed that the
