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.

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.

Suppression of nuclear factor-kappa B and mitogen-activated protein kinase signalling pathways by goshonoside-F5 extracted from Rubi Fructus.[Pubmed:
25523460 ]
Rubi Fructus, a traditional Chinese medicine, was considered as an anti-inflammatory agent in folk medicine.
METHODS AND RESULTS:
In the present study, we investigated the signalling pathways involved in the anti-inflammatory effects of Goshonoside F5 (GF5), isolated from Rubi Fructus, in peritoneal macrophages and examined its therapeutic effect in a mouse endotoxic shock model. GF5 decreased NO and PGE2 production in LPS-stimulated macrophages (IC50=3.84 and 3.16μM). This effect involved the suppression of NOS-2 and COX-2 gene expression at the transcriptional level. Examination of the effects of GF5 on NF-κB signalling demonstrated that it inhibits the phosphorylation of IκB-α and IκB-β, blocking their degradation and the nuclear translocation of the NF-κB p65 subunit. Moreover, inhibition of MAPK signalling was also observed, and phosphorylation of p38 and JNK was suppressed in the presence of GF5. Inflammatory cytokines, including IL-6 and TNF-α, were down-regulated by this compound after activation with LPS (IC50=17.04 and 4.09μM). Additionally, GF5 (30 and 90mg/kg, i.p.) significantly reduced the circulating cytokine levels (IL-6 and TNF-α) and increased survival in a mouse model of endotoxemia.
CONCLUSIONS:
These results show that GF5 significantly inhibits the pro-inflammatory response induced by LPS, both in vitro and in vivo. Our results provide a strong pharmacological basis for further understanding the potential therapeutic role of GF5 in inflammatory disease and shed new light on the bioactivity of ent-labdane diterpene glucoside.

Diterpene glycosides from leaves of Chinese Rubus chingii and fruits of R. suavissimus, and identification of the source plant of the Chinese folk medicine [Reference:
WebLink]
METHODS AND RESULTS:
Five diterpene glycosides, goshonoside F1, goshonoside F2, goshonoside F3, goshonoside F4 and Goshonoside F5(4-8), which are characteristic of the leaves of Japanese R. chingii(Gosho-ichigo), were isolated from the leaves of Chinese R. chingii(Zhan-yei fu-pen-zi). This proved the chemotaxonomical identity of the plants.
CONCLUSIONS:
Compound 8 was also detected in commercial Chinese folk medicine, Fu-pen-xi, indicating that the source plant of this drug is R. chingii. Rubusoside (1), which is the sweet diterpene gfycoside of the leaves of R. suavissimus(Chinese name: Gan-yei xuen-gou-zi), was also identified in fruits of the plant.
