Three new briarane diterpenes, juncins O-Q (1-3), along with five known briaranes, praelolide, junceellin A, gemmacolide A, gemmacolide B, and junceellolide D, were isolated from the EtOH/CH(2)Cl(2) extracts of the South China Sea gorgonian coral Junceella juncea. The structures of 1-3 were established by extensive spectroscopic analysis, including 1D and(More)
A new steroidal glycoside, bebrycoside (1), was isolated from the South China Sea gorgonian coral Bebryce indica. The structure of 1 was established by extensive spectroscopic analysis, including 1D and 2D NMR data. This was the first time that the steroidal glycoside was isolated from the genus of Bebryce.
A new steroidal glycoside--4'-O-acetyl-3-O-[beta-D-arabino-pyranosyl-oxy]-cholest-5-ene-3beta,19-diol (1), and a new glycerol derivative--1,2-O-[2'-hydroxyoctadecyl]-glycerol (2), along with 16 known compounds were isolated from the EtOH/CH2Cl2 extracts of the South China Sea gorgonian coral Junceella juncea. The structures of 1 and 2 were established by(More)
Five glycerol derivatives (1-5) and three sterols (6-8) were isolated from the EtOH extraction of the brown alga of Sargassum parvivesiculosum. On the basis of spectroscopic methods, their structures were elucidated as 1,3-di-O-[2',2'-di-(p-phenylene) isopropylidene] glycerol (1), (2S)-1-O-heptatriacontanoyl glycerol (2),(More)
A new triterpenoid saponin, 3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl subprogenin D (1), together with six known triterpenoids: subprogenin D (2), abrusgenic acid (3), triptotriterpenic acid B (4), abruslactone A (5), abrusogenin (6) and abrusoside C (7) were isolated from the leaves and stems of Abrus precatorius. Their structures were elucidated on(More)
