TL;DR: In this paper, three new acylated cholestane glycosides were found in the bulbs of Ornithogalum saundersiae and their structures were elucidated, on the basis of the spectroscopic data and chemical evidences, and by comparing them with those of known compounds.

TL;DR: In this paper, 27 Al NMR spectroscopy was applied to the analysis of intact tea leaves and model Al complexes such as Al-catechin, Al-F, Alphenolic acid and Al-organic acid.

TL;DR: Salutaridine, the key intermediate in morphine biosynthesis, is formed from ( R )-reticuline by a regio- and stereoselective para-ortho oxidative coupling catalysed by this microsomal cytochrome P-450 enzyme.

TL;DR: The formation of hydroxyl radicals in Fenton-type reactions involving ferric-EDTA chelate was enhanced by flavonoid, and the role of the iron chelator on the influence of flavonoids on hydroxym radical formation inFenton- type reactions is discussed.

TL;DR: In this paper, the absolute configurations of diastereomeric aglycones were established as (6 R, 9 R ) and (6R, 9 S ), respectively, by CD correlation as well as 1 H NMR analysis of their corresponding ( R )-(−)-α-phenylpropionic acid esters.

TL;DR: A new curcumin analogue has been isolated from the rhizomes of Curcuma xanthorrhiza along with four known Curcuminoids, and its structure has been determined as 1-(4-hydroxy-3,5-dimethoxyphenyl)-7-(4hydrox-3-methoxymethyl)-(1E,6E)-1,6-heptadiene)-3,4-dione by spectral data as mentioned in this paper.

TL;DR: The chemical structures of two major anthocyanins in purple sweet potato, Ipomoea batatas cv Yamagawamurasaki, have been identified as 3-caffeylferulysophoroside-5-glucosides of cyanidin and peonidin by FAB-MS and NMR.

TL;DR: In this article, novel chromans, hericenones F, G and H were isolated from the mushroom Hericium erinaceum, and these compounds stimulated the synthesis of nerve growth factor (NGF) in vitro.

TL;DR: Evaluation of the pyrrolizidine alkaloids of Senecio jacobaea and S. erucifolius from different geographic locations revealed the existence of different chemotypes, which were established within each species.

TL;DR: Six anthocyanins were isolated from cell suspension cultures of an Afghan cultivar of Daucus carota by PC or HPLC and unusual 1H NMR chemical shifts and 1H NOE data indicate an intramolecular copigmentation of the aglycone with these aromatic residues.

TL;DR: The metabolism of purine nucleotides and purine alkaloids are reviewed in tea and coffee plants and the activity of the three N -methyltransferases is considered.

TL;DR: Two caffeoylquinic acids were isolated from flowers of A. chamissonis ssp. foliosa var. incana and their structures were established on the basis of spectral data.

TL;DR: Two caffeoyl esters with antiviral properties were isolated from the leaves and stems of Spondias mombin by means of a bioguided assay and showed antiviral activities against Coxsackie and Herpes simplex viruses.

TL;DR: A new saponin has been isolated from the molluscicidal extract of the fruits of Tetrapleura tetraptera as discussed by the authors, which was a monodesmosidic diglycoside of the rare sapogenin 27-hydroxyolean-12(13)-en-28-oic acid.

TL;DR: In this paper, three novel dimeric sesquiterpenes, shizukaols, B, C and D, which consist of two lindenane (modified eudesmane) units were isolated from the roots of Chloranthus serratus were elucidated by 1D-and 2D-NMR analyses and by chemical methods.

TL;DR: A mechanism for the biogenesis of the C-24 alkyl group in phytosterols is given and the biochemically predictable positions of 13C labels in sitosterol are confirmed.

TL;DR: Five new flavonol glycosides were isolated from the leaves of Ginkgo biloba and their structures determined by spectroscopy and hydrolysis experiments.

TL;DR: There was a good correlation between flower colour, anthocyanidin type and pollination vector, and the four most common pigments in the Labiatae are thus cyanidin and delphinidin 3-(6″-p-coumarylglucoside)-5-(6‴-malonylglUCoside), present as the cis and trans isomers.

TL;DR: It is shown that the oligomers can be used as chemotaxonomic markers for the Rosaceae family, and hydrolysable tannin monomers were widely distributed in the herbaceous and frutescent Rosoideae species, but not in the arborous species of the other subfamilies.

TL;DR: These analyses revealed that the wall-bound material recovered from elicited cells had the features of true gymnosperm lignin and that a significantly greater amount of lign in accumulated in eliciting cells than in control cultures.

TL;DR: Three new lignanamides, named cannabisin B, C and D, were isolated from the fruits of Cannabis sativa and their structures have been elucidated based on spectral and chemical evidence.

TL;DR: In this article, a review of acetylenes and related compounds, such as alkamides, sulphur compounds, isocoumarins and lactones, which have been isolated from the tribe Anthemideae (Asteraceae) are listed.
