Two new phenols, 2(S)-2',7-dihydroxy-5,8-dimethoxyflavanone (1) and (S)-2-(4-hydroxyphenyl)-6-methyl-2,3-dihydro-4H-pyran-4-one (2), were isolated from the ethanol extract of Scutellaria barbata. Their structures were elucidated on the basis of spectroscopic analysis. © 2011. Source

Four new neo-clerodane diterpenoids, scutebarbatines W-Z (1-4), were isolated from the ethanol extract of Scutellaria barbata (Labiatae), and their structures were elucidated on the basis of extensive spectroscopic studies. In addition, the proposed structures of at least seven 13-spiro subtype neo-clerodanes: scutehenanine B (5), scutebarbatine G (6), 6-O- nicotinoylscutebarbatine G (7), barbatin A (8), 6,7-di-O- nicotinoylscutebarbatine G (9), 6-O-nicotinoyl-7-O-acetylscutebarbatine G (10), and scutebarbatine F (11), reported by Dai and co-workers from the same species, were incorrectly assigned and have been revised by reanalysis of the published NMR data. © 2010 Pharmaceutical Society of Japan.

Objective: To study sesquiterpenoids of Coniogramme maxima. Method: Chemical constituents were separated by chromatography and their structures were identified according to physicochemical property and spectrum data. Result: Fifteen compounds were separated by chromatography technique. Their structures were determined by spectral data, including 10 sesquiterpenoids as (3S)-pteroside D (1), epi-pterosin L (2), pterosin D (3), onitin (4), pterosin Z (5), onitisin (6), onitisin-glucopyranoside (7), onitin-15-O-β-D- glucopyranoside (8), (2S,3R)-pterosin-L-2′-O-β-D-glucopyranoside (9) and (3R)-peterosin D-3-O-β-D-glucopyranoside (10). The other compounds were uracil (11), 3,4-dihydroxybenzaldehyde (12), 5-hydroxymethyl-2- furancarboxaldehyde (13), β-sitosterol (14) and daucosterol (15). Conclusion: The above 15 compounds are separated from C. maxima for the first time, including 9 compounds being first separated from genus Coniogramme. Source

Four new iridoid glycosides, 6-O-benzoylphlorigidoside B (1), 6-O-trans-cinnamoylphlorigidoside B (2), 6-O-trans-p-coumaroylshanzhiside methyl ester (3), and 4'-O-trans-p-coumaroylmussaenoside (4), were isolated from the EtOH extract of the twigs and leaves of Callicarpa formosana var. formosana. Their structures were elucidated by extensive spectroscopic analysis. © 2010 Taylor & Francis. Source

Three novel chalcones bearing a long-chain alkylphenol, galanganones A-C (1-3), were isolated from the rhizomes of Alpinia galanga. Their structures were elucidated by extensive spectroscopic analysis including 2D NMR experiments. Compounds 1-3 represent the first examples of long-chain alkylphenol-coupled chalcone. © 2015 Taylor & Francis. Source
