    Biological Activity
    Description: Asperuloside exerts its anti-inflammatory effect in correlation with inhibition of a pro-inflammatory mediator through suppressing nuclear factor kappa-B (NF-κB) nuclear translocation and MAPK phosphorylation in a dose-dependent manner. Chronic administration of Asperuloside stimulates anti-obesity and anti-metabolic syndrome activity in HFD-fed rats across several organs, similar to Eucommia leaf extract (ELE) administration.
    Targets: Glut | TNF-α | ERK | JNK | p38MAPK | NF-kB | IL Receptor

    Pretreatment with the compound asperuloside decreases acute lung injury via inhibiting MAPK and NF-κB signaling in a murine model.[Pubmed: 26710167 ]
    Asperuloside, an iridoid glycoside found in Herba Paederiae, is a component from traditional Chinese herbal medicine.
    In this study, we aimed to investigate the protective effects and potential mechanisms of Asperuloside action on inflammatory responses in lipopolysaccharide (LPS)-stimulated Raw 264.7 cells and an LPS-induced lung injury model. The pro-inflammatory cytokines and signaling pathways were measured by enzyme-linked immunosorbent assays (ELISA) and Western blotting to determine the effects of Asperuloside. We found that Asperuloside can significantly downregulate tumor necrosis factor alpha (TNF-α), interleukin (IL)-1β, and IL-6 levels in vitro and in vivo, and treatment with Asperuloside significantly reduced the lung wet-to-dry weight, histological alterations and myeloperoxidase activity in a murine model of LPS-induced acute lung injury (ALI). In addition, Western blot analysis that pretreatment with Asperuloside remarkably blunted the phosphorylation of inhibitor of nuclear factor kappa-B (IκBα), extracellular signal-related kinases 1 and 2 (ERK1/2), c-Jun. N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (p38MAPK) in LPS-stimulated inflammation.
    These results indicate that Asperuloside exerts its anti-inflammatory effect in correlation with inhibition of a pro-inflammatory mediator through suppressing nuclear factor kappa-B (NF-κB) nuclear translocation and MAPK phosphorylation in a dose-dependent manner.

    Asperuloside stimulates metabolic function in rats across several organs under high-fat diet conditions, acting like the major ingredient of Eucommia leaves with anti-obesity activity.[Pubmed: 25191539]
    Eucommia leaves (Eucommia ulmoides Oliver) contain chlorogenic acid (a caffeic acid derivative) and geniposidic acid and Asperuloside (ASP), iridoid glucosides used in beverages.
    We used a metabolic syndrome rat model, produced by feeding a 35 % high-fat diet (HFD), to examine potential anti-obesity and anti-metabolic syndrome effects and mechanisms of chronic administration of ASP. These effects were compared with Eucommia leaf extract (ELE), the positive control, which exhibits anti-obesity effects. A total of six rats were studied for 3 months in five groups. ASP suppressed body weight, visceral fat weight, food intake and circulating levels of glucose, insulin and lipids, and increased the plasma adiponectin level in rats on a HFD. These effects are similar to those of ELE, except for the influence on the plasma glucose level. RT-PCR studies showed that ASP (like ELE with known anti-obesity effects) diminished isocitrate dehydrogenase 3α, NADH dehydrogenase flavoprotein 1 (Comp I) mRNA and fatty acid synthase levels (white adipose tissue), increased carnitine palmitoyltransferase 1α and acyl-CoA dehydrogenase, very-long-chain mRNA levels (liver), and increased Glut4, citrate synthase, isocitrate dehydrogenase 3α, succinyl CoA synthase, peroxisomal 3-ketoacyl-CoA thiolase, dihydrolipoamide succinyl transferase and succinate dehydrogenase mRNA levels (skeletal muscle) under HFD conditions. Interestingly, ASP administration resulted in significantly increased mRNA levels of uncoupling protein 1 (UCP1) in the brown adipose tissue of HFD-fed rats; ELE did not affect the expression of UCP1. The increased expression of UCP1 may be negated by many ingredients other than ASP in the ELE.
    These findings suggest that chronic administration of ASP stimulates anti-obesity and anti-metabolic syndrome activity in HFD-fed rats across several organs, similar to ELE administration; thus, ASP may be an important ingredient of ELE.
    Asperuloside Description
    Source: The herbs of Galium aparine L.
    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.

    Monoterpenoids glycosides content from two Mediterranean populations of Crucianella maritima L.[Pubmed: 24499293]

    In this study, the iridoidic content of two accessions of Crucianella maritima L., one from Sardinia and the second from Latium, was examined and compared. From a qualitative point of view, the iridoidic pattern of the two samples was similar, since the same compounds (Asperuloside, asperulosidic acid and deacetyl asperulosidic acid) were isolated. Asperuloside was the main compound in both accessions. Asperulosidic acid was the second compound in the accession from Sardinia, while the accession from Latium exhibited a similar amount of asperulosidic acid and deacetyl asperulosidic acid.
    These iridoids can be considered as chemotaxonomic markers for parts of the Rubiaceae family, in particular for the Rubioideae subfamily to which C. maritima belongs.
