Erigeside C | CAS:112667-09-1 | Manufacturer ChemFaces

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.

Phenolic glycosides from Lindera obtusiloba and their anti-allergic inflammatory activities.[Pubmed: 23513723]

Eight phenolic glycosides, tachioside (1), isotachioside (2), koaburaside (3), 2,6-dimethoxy-4-hydroxyphenyl-1-O-beta-D-glucopyranoside (4), 4,6-dihydroxy-2-methoxyphenyl-1-O-beta-D-glucopyranoside (5), a mixture of Erigeside C (6a) and salidroside (6b), and 6-hydroxyphenyl)-1-O-beta-D-glucopyranoside (7) were isolated from the stems of Lindera obtusiloba Blume. The structures of the isolates were determined by 1H-, 13C-NMR, COSY, HMQC, and HMBC spectroscopy.
METHODS AND RESULTS:
To evaluate their anti-allergic inflammatory activities, the inhibitory effects of isolates (1-7) on histamine release and on the gene expressions of tumor necrosis factor (TNF)-a and interleukin (IL)-6 were examined using human mast cells; previous studies have reported that TNF-alpha and IL-6 release from mast cells is positively related to the severity of allergic symptoms. Of the tested compounds, koaburaside (3), 2,6-dimethoxy-4-hydroxyphenyl-1-O-beta-D-glucopyranoside (4), and (6-hydroxyphenyl)-1-O-beta-D-glucopyranoside (7) suppressed histamine release from mast cells as compared with gallic acid (positive control). In particular, 6-hydroxyphenyl)-1-O-beta-D-glucopyranoside (7) attenuated the gene expressions of the proinflammatory cytokines TNF-alpha and IL-6 in human mast cells.
CONCLUSIONS:
Our results support the notion that phenolic glycosides isolated from L. obtusiloba inhibit mast-cell-derived allergic inflammation, histamine, and proinflammatory cytokines.
