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. |

Triterpenoid saponin, oleanolic acid 3-O-beta-d-glucopyranosyl(1-->3)-alpha-l-rhamnopyranosyl(1-->2)-alpha-l-arabinopy ranoside (OA) from Aralia elata inhibits LPS-induced nitric oxide production by down-regulated NF-kappaB in raw 264.7 cells.[Pubmed:17910942]
Arch Biochem Biophys. 2007 Nov 15;467(2):227-33.
It is well known that the pro-inflammatory mediators such as nitric oxide (NO) and prostaglandin (PG)E(2) are involved in several inflammatory diseases and lipopolysaccharide (LPS) can stimulate these inflammatory responses. Oleanolic acid 3-O-beta-d-glucopyranosyl(1-->3)-alpha-l-rhamnopyranosyl(1-->2)-alpha-l-arabinopy ranoside (OA) was purified from edible plant Aralia elata. OA inhibited LPS-induced NO and PGE(2) production in raw 264.7 murine macrophages in a dose-dependent manner and RT-PCR analysis indicated OA inhibited mRNA transcriptions of iNOS and COX-2 genes in LPS-induced cells. EMSA and Western blot analysis revealed that OA drastically reduced NF-kappaB translocation by the inhibition effects of LPS-induced phosphorylation of IkappaBalpha. In addition, it was found that OA inhibited the phosphorylation of ERK1/2, p38 and JNK MAPK, and the treatment of U0126 in LPS-induced raw 264.7 cells showed significant inhibition activity on the NO production and the phosphorylation of IkappaBalpha. Taken together, it is suggested that OA from A. elata has an anti-inflammatory activity via down-regulation of NF-kappaB.
