Four new 2-(2-phenylethyl)chromone derivatives (1-4) were isolated from the EtOH extract of Chinese agarwood produced via the whole-tree agarwood-inducing technique, coming from Aquilaria sinensis (Lour.) Spreng. (Thymelaeaceae). Their structures were elucidated by extensive spectroscopic methods, such as UV, IR, MS, 1D as well as 2D NMR. All of the isolates were then assessed for their anti-in...
Three new sesquiterpenoids (1-3) and one new sesquiterpenoid derivative (4), along with three known sesquiterpenoids (5-7), were isolated from the 95% ethanolic extract of Chinese eaglewood [Aquilaria sinensis (Lour.) Gilg]. The structures of these compounds were elucidated through extensive analysis of spectroscopic data including IR, NMR, HRESIMS, and X-ray diffraction experiments. In additio...
Five 2-(2-phenylethyl)chromones including a new one, (5S,6R,7S,8R)-5,8-dichloro-6,7-dihydroxy-2-phenylethyl-5,6,7,8-tetrahydro-4H-chromen-4-one (1), and four known ones (2-5), were isolated from 150 mM NaCl-elicited Aquilaria sinensis cell suspension cultures. In addition, three feruloyl amides (6-8), six nucleosides (9-14), (+)-syringaresinol (15), indole-3-carboxaldehyde (16), and two glycosi...
Agarwood, a kind of highly valued non-timber product across Asia, is formed only when its resource trees--the endangered genus Aquilaria are wounded or infected by some microbes. To promote the efficiency of agarwood production and protect the wild resource of Aquilaria species, we urgently need to reveal the regulation mechanism of agarwood formation. MicroRNAs (miRNAs) are a group of gene exp...
مقدمه: گیاه عود یا عودالهندی با نام علمی (Lour.) Gilg. IV. Aquilaria sinensis که در زبان انگلیسی به آنIncense Tree گفته میشود، گیاهی است که به صورت درختی میروید و بومی جنوب شرق آسیا است. این گیاه به تیره Thymelaeaceae تعلق دارد. این گونه گیاهی نخستین بار در هنگ کنگ روییده و چوب آن به شرقیترین مناطق در چین و یا حتی به سرزمینهای دوری همچون عربستان صادر میشده است. هدف: شناسایی ترکیبات شیمی...
The composition and antimicrobial activity of the essential oils which were obtained from agarwood originated from Aquilaria sinensis (Lour.) Gilg stimulated by the chemical method (S1) were characterized, taking wild agarwood (S2) and healthy trees (S3) respectively as the positive and negative controls. The chemical composition of S1 was investigated by gas chromatography-mass spectrometry (G...
