Characterization and Determination of 2-(2-Phenylethyl)chromones in Agarwood by GC-MS
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. Expand
2-(2-phenylethyl)chromone derivatives in Chinese agarwood "Qi-Nan" from Aquilaria sinensis.
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. Expand
A Fatty Acid Glycoside from a Marine-Derived Fungus Isolated from Mangrove Plant Scyphiphora hydrophyllacea
To study the antimicrobial components from the endophytic fungus A1 of mangrove plant Scyphiphora hydrophyllacea Gaertn. F., a new fatty acid glucoside was isolated by column chromatography from theExpand
Phenolic compounds from Dalbergia odorifera
Abstract Six new phenolic compounds ( 1 – 6 ), along with five known phenolics ( 7 – 11 ) were isolated from the heartwood of Dalbergia odorifera T. Chen. (Leguminosae). Their structures wereExpand
A New 2-(2-Phenylethyl)Chromone from Chinese Eaglewood
A new 2-(2-phenylethyl)chromone, 5,6,7,8-tetrahydroxy-2-(3-hydroxy-4-methoxyphenethyl)-5,6,7,8-tetrahydro-4H-chromen-4-one (1) was isolated from the Chinese eaglewood [Aquilaria sinensis (Lour.)Expand
Cytotoxic cardenolide glycosides from the seeds of Antiaris toxicaria.
Bioassay-guided fractionation of the ethanolic extract from the seeds of Antiaris toxicaria led to the isolation of three new cardiac glycosides named toxicarioside J, toxicarioside K, andExpand
Two New Flavonoids from Dragon's Blood of Dracaena cambodiana
Phytochemical investigation on dragon's blood of Dracaena cambodiana led to the discovery of two new flavonoid derivatives, cambodianin G (1) and cambodianin H (2). Their structures were elucidatedExpand
Two new epimeric pairs of iridoid from mangrove plant Scyphiphora hydrophyllacea
Two new epimeric pairs of iridoid scyphiphin A(1) (1a), A2 (1b) and scyphiphin B-1 (2a), B-2 (2b) were isolated from Scyphiphora hydrophyllacea Gaertn. F. Their structures were elucidated byExpand
A new sesquiterpene lactone from Elephantopus tomentosus
A new sesquiterpene lactone, named tomenphantopin H, together with two known germacranolides, exhibited antibacterial activity and was isolated from the whole plant of Elephantopus tomentosus Linn. Expand
