Development of a quantitation method to assay both lyoniresinol enantiomers in wines, spirits, and oak wood by liquid chromatography-high resolution mass spectrometry.[Pubmed:27000563]

Anal Bioanal Chem. 2016 May;408(14):3789-99.

Wine taste balance evolves during oak aging by the release of volatile and non-volatile compounds from wood. Among them, an enantiomer of lyoniresinol, (+)-lyoniresinol, has been shown to exhibit bitterness. To evaluate the impact of (+)-lyoniresinol on wine taste, a two-step quantitation method was developed and validated. First, (+/-)-lyoniresinol was assayed in wines, spirits, and oak wood macerates by C-18 liquid chromatography-high resolution mass spectrometry (LC-HRMS). Then, the lyoniresinol enantiomeric ratio was determined by chiral LC-HRMS in order to calculate the (+)-lyoniresinol content. In red and white wines, the average concentrations of (+)-lyoniresinol were 1.9 and 0.8 mg/L, respectively. The enantiomer proportions were not affected by bottle aging, and lyoniresinol appeared to remain stable over time. The sensory study of (+)-lyoniresinol established its perception threshold at 0.46 mg/L in wine. All the commercial wines quantitated were above this perception threshold, demonstrating its impact on wine taste by an increase in bitterness. In spirits, (+)-lyoniresinol ranged from 2.0 to 10.0 mg/L and was found to be released continuously during oak aging. Finally, neither botanical origin nor toasting was found to significantly affect the (+)-lyoniresinol content of oak wood.

Enhanced anti-oxidative effect of fermented Korean mistletoe is originated from an increase in the contents of caffeic acid and lyoniresinol.[Pubmed:27072079]

Food Funct. 2016 May 18;7(5):2270-7.

Viscum album var. coloratum (Korean mistletoe; KM) is an herbal medicine that is used worldwide for the treatment of various immunological disorders and cancers. KM extract showed enhanced anti-oxidative effects in 2,2-diphenyl-1-picrylhydrazyl, Trolox equivalent antioxidant capacity, and 5-(and-6)-chloromethyl-2',7'-dichlorodihydrofluorescein diacetate acetyl ester assays after being fermented with a crude enzyme extract from a soybean paste fungus, Aspergillus kawachii. High-performance liquid chromatography analysis showed four increased peaks in enzyme treated KM. The increased peaks were isolated and identified as caffeic acid (1), hesperetin (2), syringaldehyde (3), and lyoniresinol (4). Among the four compounds, only 1 and 4 showed strong anti-oxidative activity. Therefore, the fermentation increased the contents of 1 and 4, which consequently increased the anti-oxidative activity of KM.

Lyoniresinol 3alpha-O-beta-D-glucopyranoside-mediated hypoglycaemia and its influence on apoptosis-regulatory protein expression in the injured kidneys of streptozotocin-induced mice.[Pubmed:24312585]

PLoS One. 2013 Dec 3;8(12):e81772.

Averrhoa carambola L. (Oxalidaceae) root (ACLR) has a long history of use in traditional Chinese medicine for treating diabetes and diabetic nephropathy (DN). (+/-)-Lyoniresinol 3alpha-O-beta-D-glucopyranoside (LGP1, LGP2) were two chiral lignan glucosides that were isolated from the ACLR. The purpose of this study was to investigate the effect of LGP1 and LGP2-mediated hypoglycaemia on renal injury in streptozotocin (STZ)-induced diabetic mice. STZ-induced diabetic mice were administrated LGP1 and LGP2 orally (20, 40, 80 mg/kg body weight/d) for 14 days. Hyperglycaemia and the expression of related proteins such as nuclear factor-kappaB (NF-kappaB), caspase-3, -8, -9, and Bcl-associated X protein (Bax) were markedly decreased by LGP1 treatment. However, LGP2 treatment had no hypoglycaemic activity. Diabetes-dependent alterations in the kidney such as glomerular hypertrophy, excessive extracellular matrix amassing, and glomerular and tubular basement membrane thickening were improved after 14 days of LGP1 treatment. B cell lymphoma Leukaemia-2 (Bcl-2) expression was reduced in the STZ-induced diabetic mouse kidneys but was enhanced by LGP1 treatment. These findings suggest that LGP1 treatment may inhibit diabetic nephropathy progression and may regulate several pharmacological targets for treating or preventing diabetic nephropathy.

A new lyoniresinol derivative from Smilax microphylla.[Pubmed:23472472]

Nat Prod Commun. 2013 Jan;8(1):113-4.

A new lignan, lyoniresinol-9-O-8"-syringylglycerol ether (1), together with five known compounds, piceatannol (2), resveratrol (3), oxyresveratrol (4), quercetin-3'-glucoside (5) and diosgenin (6) were isolated from the rhizomes of Smilax microphylla. The structure of the new compound was determined by means of chemical evidence and 1D-and 2D-NMR (1H, 13C, HSQC, HMBC, 1H-1H COSY and NOESY) spectroscopic analysis and HR-ESI-MS.

How stereochemistry influences the taste of wine: Isolation, characterization and sensory evaluation of lyoniresinol stereoisomers.[Pubmed:26320975]

Anal Chim Acta. 2015 Aug 12;888:191-8.

Wine expresses its beauty by sending a sensory message to the taster through molecules coming from grapes, yeast metabolism or oak wood. Among the compounds released during barrel aging, lyoniresinol has been recently reported as a relevant contributor to wine bitterness. As this lignan contains three stereogenic carbons, this work aimed at investigating the influence of stereochemistry on wine taste by combining analytical and sensorial techniques. First, an oak wood extract was screened by Liquid Chromatography-High Resolution Mass Spectrometry to target isomers separable in a symmetric environment and a diastereoisomer called epi-lyoniresinol was isolated for the first time. Then, an original racemic resolution based on natural xylose-derivatives was carried out to obtain lyoniresinol enantiomers. Chiroptical spectroscopic measurements associated with theoretical calculations allowed the unambiguous determination of their absolute configuration. The taste properties of all these stereoisomers revealed that only one lyoniresinol enantiomer is strongly bitter whereas the other one is tasteless and the diastereoisomer is slightly sweet. The presence of these three compounds was established in an oaked Bordeaux wine by chiral and non-chiral chromatography, suggesting the significant influence of stereochemistry on wine taste.
