General tips：For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging：1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition：Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

From the ethanol extract of the Anemarrhena asphodeloides Buge (Liliaceae), a new steroidal suponin Anemarsaponin B and two known saponins anemarsaponin A1 and A2 were isolated. On the basis of chemical evidences and spectral analysis (UV, IR, EI-MS, FAB-MS, 1H-NMR and 13C-NMR), the structure of Anemarsaponin B was elucidated as 26-O-beta-D-glucopyranosylfurost-20(22)-ene-3 beta,26-diol-3-O-beta-D- glucopyranosyl(1----2)-beta-D-galactopyranoside. Preliminary pharmacological tests showed that Anemarsaponin B could inhibit PAF-induced rabbit platelet aggregation in vitro.

Anti-inflammatory effect of anemarsaponin B isolated from the rhizomes of Anemarrhena asphodeloides in LPS-induced RAW 264.7 macrophages is mediated by negative regulation of the nuclear factor-kappaB and p38 pathways.[Pubmed:19375480]

Food Chem Toxicol. 2009 Jul;47(7):1610-7.

Anemarrhena asphodeloides is widely used in traditional Chinese medicine, and is known to have anti-diabetic and diuretic effects. In this study, we evaluated the anti-inflammatory effects of Anemarsaponin B (ASB), a steroidal saponin isolated from the rhizomes of A. asphodeloides (Liliaceae), in LPS-stimulated RAW 264.7 macrophage cell line. ASB significantly and dose-dependently decreased the protein and mRNA levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). ASB also reduced the expressions and productions of pro-inflammatory cytokines, including those of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6). Electrophoretic mobility shift assay (EMSA) and reporter gene assays revealed that ASB attenuated the LPS-induced DNA binding and transcriptional activity of nuclear factor-kappa B (NF-kappaB). In addition, it was found that pretreatment with ASB significantly inhibited the nuclear translocation of the p65 subunit of NF-kappaB by blocking the phosphorylation of inhibitory kappa B-alpha (IkappaB-alpha). On the other hand, ASB inhibited the phosphorylation of MAP kinase kinases 3/6 (MKK3/6) and mixed lineage kinase 3 (MLK3), which are both involved in the p38 pathway. Taken together, these results suggest that anti-inflammatory effect of ASB in LPS-treated RAW 264.7 macrophages is associated with the inhibition of NF-kappaB transcriptional activity, possibly via the p38 MAP kinase pathway.

Description

Anemarsaponin B is a steroidal saponin isolated from the rhizomes of A. asphodeloides (Liliaceae). Anemarsaponin B decreases the protein and mRNA levels of iNOS and COX-2. Anemarsaponin B reduces the expressions and productions of pro-inflammatory cytokines, including TNF-a and IL-6. Anemarsaponin B inhibits the nuclear translocation of the p65 subunit of NF-κB by blocking the phosphorylation of IκBα. Anemarsaponin B also inhibits the phosphorylation of MAP kinase kinases 3/6 (MKK3/6) and mixed lineage kinase 3 (MLK3). Anti-inflammatory effect .
