Biological Activity
Description: 6'-O-caffeoylarbutin may serve as a skin-whitening ingredient with the merits of potent melanin inhibition,less toxicity and reversible melanin synthesis after stopping use.
In vitro:
Phytochemistry, 2007, 68(9):1321-1326.
Phenylethanoids, iridoids and a spirostanol saponin from Veronica turrilliana.[Reference: WebLink]

METHODS AND RESULTS:
From the aerial parts of Veronica turrilliana two phenylethanoid glycosides, turrilliosides A and B and a steroidal saponin, turrillianoside were isolated and their structures elucidated as beta-(3,4-dihydroxyphenyl)ethyl-4-O-E-caffeoyl-O-[beta-glucopyranosyl-(1 -> 4)-alpha-rhamnopyranosyl-(1 -> 6)]-beta-glucopyranoside, beta-(3,4-dihydroxyphenyl)ethyl-4-O-E-caffeoyl-[6-O-E-feruloyl-beta-gluc opyranosyl-(1 -> 4)-alpha-rhamnopyranosyl-(1 -> 6)]-beta-glucopyranoside and (23S, 25S)-12 beta,23-dihydroxyspirost-5-en-3 beta-yl O-alpha-rhamnopyranosyl-(1 -> 4))-beta-glucopyranoside, respectively. Furthermore, eight known glucosides are reported namely, catalpol, catalposide, verproside, amphicoside, isovanilloylcatalpol, aucubin, arbutin, and 6-O-E-caffeoylarbutin(6-O-Caffeoylarbutin), the latter two for the first time in the genus Veronica.
CONCLUSIONS:
The two phenylethanoid glycosides were found to be potent DPPH radical scavengers. All of the tested compounds were inactive against the representative species of fungi and bacteria.

Source: The herbs of Viburnum dilatatum Thunb.
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.
