    Urolignoside Description
    Source: The herbs of Lysimachia clethroides
    Biological Activity or Inhibitors: 1. Urolignoside shows antioxidant and radical scavenging activities.
    Solvent: DMSO, Pyridine, Methanol, Ethanol, etc.
    Storage: 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: service@chemfaces.com

    After receiving: 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.

    Phenolic constituents in the fruits of Cinnamomum zeylanicum and their antioxidant activity.[Pubmed: 16506818]
    Defatted cinnamon fruit powder was successively extracted with benzene ethyl acetate, acetone, MeOH, and water. The concentrated water extract contained the maximum amount of phenolics and showed the highest antioxidant activities. Hence, it was fractionated by Diaion HP-20SS, Diaion HP-20, and Sephadex LH-20 column chromatographies. It gave five purified compounds, the purities of which were analyzed by HPLC. Compounds 1-5 were identified as 3,4-dihydroxybenzoic acid (protocatechuic acid), epicatechin-(2beta-->O-7,4beta-->8)-epicatechin-(4beta-->8)-epicatechin (cinnamtannin B-1), 4-[2,3-dihydro-3-(hydroxymethyl)-5-(3-hydroxypropyl)-7-(methoxy)benzofuranyl]-2-methoxyphenyl beta-d-glucopyranoside (Urolignoside), quercetin-3-O-(6-O-alpha-l-rhamnopyranosyl)-beta-d-glucopyranoside (rutin), and quercetin-3-O-alpha-l-rhamnopyranoside by using extensive spectral studies. The antioxidant activities of purified compounds were screened for their antioxidative potential using beta-carotene-linoleate and 1,1-diphenyl-2-picrylhydrazyl model systems. All of the compounds showed antioxidant and radical scavenging activities. This is the first report of the isolation and identification of nonvolatile constituents and as well as antioxidant activities from cinnamon fruits.

    A new megastigmane glycoside from the aerial parts of Cirsium setosum.[Pubmed: 24359780 ]
    To study the chemical constituents of the aerial parts of Cirsium setosum (Willd.) MB.. METHODS: The chemical constituents were isolated and purified by various chromatographic techniques. Their structures were determined on the basis of physical properties and spectroscopic data. RESULTS: A new megastigmane glycoside and six known compounds were obtained and identified as (7E, 9R)-9-hydroxy-5, 7-megastigmadien-4-one-9-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyanoside (1), (6R, 7E, 9R)-9-hydroxy-4, 7-megastigmadien-3-one-9-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside (2), Urolignoside (3), 4, 9, 9'-trihydroxy-3, 3'-dimethoxy-8-O-4$\prime $-neolignan-7-O-β-D-glucopyranoside (4), citroside A (5), salidrosidin (6), and adenosine (7). CONCLUSION: Compound 1 is a new megastigmane glycoside, named as Xiaojiglycoside A.
