|Lignans from the stems of Clematis armandii ("Chuan-Mu-Tong") and their anti-neuroinflammatory activities.[Pubmed: 24661966 ]|
METHODS AND RESULTS:
One new and sixteen known lignans were isolated and characterized. The absolute configuration of the new lignan, (7R,8S)-9-acetyl-dehydrodiconiferyl alcohol (1), was elucidated by a combination of 1D/2D NMR techniques and the Electronic Circular Dichroism (ECD) spectroscopy based on the empirical helicity rules.
The anti-neuroinflammatory bioassay showed that compounds 1, (7R,8S)-dehydrodiconiferyl alcohol (2), erythro-guaiacylglycerol-β-coniferyl ether (5), and erythro-Guaiacylglycerol beta-coniferyl ether (6) displayed significant inhibitory effects on NO production. Among them, neolignans 1 and 2 exhibited more potent activities than the positive control (N(G)-monomethyl-L-arginine, L-NMMA), with an IC₅₀ value of 9.3 and 3.9 μM, respectively. Moreover, both 1 and 2 were also found to concentration-dependently suppress the TNF-α release in LPS-stimulated BV-2 cells.
erythro-Guaiacylglycerol beta-coniferyl ether Description
||The herbs of Leucaena leucocephala
||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Need more advice on solubility, usage and handling? Please email to: email@example.com
||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

|Chemical constituents from stems of Aquilaria sinensis[Pubmed: 24380305]|
|To study the constituents from the stems of Aquilaria sinensis. |
METHODS AND RESULTS:
The chemical constituents were isolated by various column chromatographic methods.
The structures were identified by spectral analysis including NMR and MS data. Sixteen compounds were isolated and identified as threo-buddlenol C (1), thero-ficusesquilignan A (2), erythro-buddlenol C (3), (+/-) buddlenol D (4), (-) medioresinol (5), (-) pinoresinol (6), 5'-methoxy lariciresinol (7), erythro-Guaiacylglycerol beta-coniferyl ether(8), thero-guaiacylglycerol-beta-coniferyl ether (9), herpetin (10), (+) syringaresinol (11), curuilignan (12), ciwujiatone (13), coniferyl alcohol (14), 3, 4, 5-trimethoxyphenol (15) and cucurbitacin (16).
All the compounds, except for 11-13 were obtained from A. sinensis for the first time.
