Vaccarin E Description

Source:	The seeds of Vaccaria segetalis
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.

C-glycosylflavone with rotational isomers from Vaccaria hispanica (Miller) Rauschert seeds.[Reference: WebLink]

METHODS AND RESULTS:
Five C-glycosylflavone were isolated from Vaccaria hispanica (Miller) Rauschert seeds. Their NMR spectra showed separate signals because of the existence of rotational isomers, which is an unusual phenomenon.
CONCLUSIONS:
The spectroscopic data revealed that compounds 1–5 were identified as apigenin 6-C-[α-l-arabinopyranosyl-(1′′′→2′′)-β-d-glucopyranosyl]-7-O-β-d-glucopyranoside (1), apigenin 6-C-[α-l-arabinopyranosyl-(1′′′→2′′)-β-d-glucopyranosyl]-7-O-(6′′′′-O-dihydroferuloyl)-β-d-glucopyranoside (2), apigenin 6-C-β-d-glucopyranosyl-7-O-(6′′′-O-dihydroferuloyl)-β-d-glucopyranoside (3) and isovitexin-2′′-O-arabinoside (4) and saponarin (5), respectively. The structure of ‘vaccarin’ was revised to apigenin 6-C-[α-l-arabinopyranosyl-(1′′′→2′′)-β-d-glucopyranosyl]-7-O-β-d-glucopyranoside and consequently 1 should be named ‘vaccarin’. Among the isolated compounds, 2 and 3 are new and named Vaccarin E and vaccarin F, respectively.
