Characterization and Determination of 2-(2-Phenylethyl)chromones in Agarwood by GC-MS
TLDR
The characteristic fragmentation behaviors of the 2-(2-phenylethyl)chromones are the cleavages of the CH2-CH2 bond between chromone moiety and phenyl moiety, providing fast and reliable characterization of the quality of agarwood.
2-(2-phenylethyl)chromone derivatives in Chinese agarwood "Qi-Nan" from Aquilaria sinensis.
TLDR
Compared with other agarwoods, "Qi-Nan" was different in containing 2-(2-phenylethyl)chromones with unsubstituted chromone rings and exhibited weak inhibitory activities for acetylcholinesterase inhibitors.
Five new 5,11-epoxyguaiane sesquiterpenes in agarwood "Qi-Nan" from Aquilaria sinensis.
TLDR
Five new 5,11-epoxyguaiane sesquiterpenes, along with a known one, were isolated from high quality agarwood ‘Qi-Nan’ originating from Aquilaria sinensis and showed acetylcholinesterase inhibitory activities in different degrees.
2-(2-phenylethyl)chromone derivatives from Chinese agarwood induced by artificial holing.
TLDR
Three new 2-(2-phenylethyl)chromone derivatives (1-3) were isolated from the EtOAc extract of Chinese agarwood induced by artificial holing, originating from Aquilaria sinensis (Lour.) Gilg (Thymelaeaceae).
Five new eudesmane-type sesquiterpenoids from Chinese agarwood induced by artificial holing.
TLDR
Five new eudesmane-type sesquiterpenoids were isolated from Chinese agarwood induced by artificial holing originating from Aquilaria sinensis (Lour.) Gilg (Thymelaeaceae) and showed antibacterial activities and weak acetylcholinesterase inhibitory activity.
2-(2-Phenylethyl)chromone derivatives in artificial agarwood from Aquilaria sinensis.
Seven new 2-(2-phenylethyl)chromone derivatives (1-7) including a chlorinated one (4), together with eight known ones (8-15), were isolated from the EtOAc extract of artificial agarwood originating
A new 2-(2-phenylethyl)chromone derivative in Chinese agarwood ‘Qi-Nan’ from Aquilaria sinensis
Phytochemical analysis of the high quality Chinese agarwood ‘Qi-Nan’ originating from Aquilaria sinensis (Lour.) Glig led to the isolation of a new 2-(2-phenylethyl)chromone derivative, qinanones G
Sesquiterpenoids from Chinese Agarwood Induced by Artificial Holing
TLDR
Two new sesquiterpenoids, 3-oxo-7-hydroxylholosericin A and 1,5;8,12-diepoxy-guaia-12-one (2) were isolated from Chinese agarwood induced by artificial holing originating from Aquilaria sinensis (Lour.) Gilg.
Monitoring the Chemical Profile in Agarwood Formation within One Year and Speculating on the Biosynthesis of 2-(2-Phenylethyl)Chromones
TLDR
This is the first report that systematically analyzed dynamic changes of secondary metabolites during the process of agarwood formation and fully discussed the biosynthetic pathway of PECs.
Three new phenolic compounds from Dalbergia odorifera
TLDR
