A new cytotoxic 2-(2-phenylethyl)chromone from Chinese eaglewood

Five new eudesmane-type sesquiterpenoids from Chinese agarwood induced by artificial holing

“…Previous phytochemical studies on Chinese agarwood originating from A. sinensis were mostly concentrated on the wild agarwood, which result in the isolation of sesquiterpenoids and 2-(2-phenylethyl)chromones mainly [3][4][5][6][7]. Our previous phytochemical research on Chinese agarwood induced by artificial holing from A. sinensis led to the isolation of many 2-(2-phenylethyl)chromones [8].…”

Mathematical modeling for extraction of essential oil from Aquilaria crassna by hydrodistillation and quality of agarwood oil

“…The comminuted wood (3,000 g) was soaked in distilled water (27,000 g) for up to 7 d (Liu et al, 2008;Bhuiyan et al, 2009) in order to break down the parenchymatous and oil glands. This ratio of agarwood to distilled water (1:9) is usually applied in the industrial production of agarwood oil.…”

Five 2-(2-Phenylethyl)chromones from Sodium Chloride-Elicited Aquilaria sinensis Cell Suspension Cultures

“…Additionally, feruloyl amides, nucleosides, and lignins have been extensively reported as being involved in plant defenses [25][26][27][28]. The identification of 2-(2-phenylethyl)chromones (1)(2)(3)(4)(5), feruloyl amides (6-8), nucleosides (9)(10)(11)(12)(13)(14), and (+)-syringaresinol (15) would be useful for further exploring the mechanism of agarwood formation.…”

“…Hitherto, more than 100 congeners of 2-(2-phenylethyl)chromones have been reported, and many of them have potentially anti-inflammatory [1], neuroprotective [2], antitumor activities, etc. [3][4][5]. Under stress conditions, such as wounding or fungal infections, some resin-impregnated heartwood containing a variety of 2-(2-phenylethyl)chromones are slowly forming in the trunk and branches of some species of Thymelaeaceae.…”
