ABSTRACT

Two sesquiterpenes were isolated from the agarwood originating from Gyrinops salicifolia with various chromatographic techniques, and their structures were determined as 12-hydroxy-dihydrocyperolone(1) and(rel)-4β,5β,7β-eremophil-9-en-12,8α-olide(2), through a combined analysis of physicochemical properties and spectroscopic evidence. Compound 1 was a new compound. Compound 2 showed cytotoxicities against K562 and BEL-7401 cell lines, with IC_(50) values of(17.85±0.04) and(21.82±0.07) mg·L~(-1), respectively [taxol as positive control, with IC_(50) values of(1.97±0.11) and(6.31±0.08) mg·L~(-1)].

ABSTRACT

In order to study the chemical constituents of n-butanol fraction of ethanol extract from Chinese agarwood induced by artificial holing, various chromatographic techniques were carried out to isolate compounds, and the structures of compounds were determined through a combined analysis of physicochemical properties and spectroscopic evidence. Seven compounds were obtained and identified as selina-3,11-dien-9,15-diol (1), aquilarone D (2), 5α,6β,7α,8β-tetrahydroxy-2-[2-(2-hydroxyphenyl)ethyl]-5,6,7,8-tetrahydrochromone (3), 6,7-dimethoxy-2-[2-(4-methoxyphenyl)ethyl]chromone (4), syringin (5), methyl (Z)-p-coumarate (6), and 4'-methoxycinnamic acid (7), among which compound 1 was a new compound and compounds 5-7 were isolated from agarwood for the first time. The bioactivity assay results concluded that compounds 6 and 7 showed certain nematicidal activity against Panagrellus redivivus, and compounds 4, 6 and 7 exhibited cytotoxicity against BEL-7402, SGC-7901 and A549 carcinoma cell lines.

ABSTRACT

AIM@#To study the chemical constituents from the fermentation of the endophytic fungus HP-1 of Chinese eaglewood.@*METHODS@#The chemical constituents were isolated by column chromatography on silica gel and Sephadex LH-20, and their structures were elucidated on the basis of spectroscopic analysis.@*RESULTS@#Four compounds were isolated and identified as 3α, 3β, 10β-trimethyl-decahydroazuleno[6, 7]furan-8, 9, 14-triol (1), 4-hydroxyphenylacetic acid (2), 4-hydroxyphenethyl alcohol (3), and 5-hydroxymethyl-2-furancarboxaldehyde (4).@*CONCLUSION@#Compound 1 was a new compound. Compound 2 showed antibacterial activity against Staphylococcus aureus.
