Epicatechin pentaacetate | CAS:20194-41-6

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.

Viburnum mullaha D.DON fruit (Indian Cranberry): A Potential Source of Polyphenol with rich antioxidant, anti-elastase, anti-collagenase and anti-tyrosinase activities[Reference: WebLink]

Viburnum mullaha (Buch.-Ham. Ex D. Don), is an underexplored wild edible fruit of Indian Himalayan region, analysed for total polyphenol contents, antioxidant, anti-elastase, anticollagenase, anti-tyrosinase activities using in-vitro assays.
METHODS AND RESULTS:
High values of total phenolic contents of 1257±40 mg gallic acid equivalents/100 g fruit weight (FW) and total flavonoid contents of 3501±203 mg catechin equivalents/100 g FW were observed. V. mullaha fruit extracts showed outstanding antioxidant activities (ABTS+, DPPH, superoxide anion, linoleate Accepted Manuscript peroxyl radicals scavenging and ferric reducing activities) and remarkable anti-elastase, anticollagenase and anti-tyrosinase activities. High resolution liquid chromatography–mass spectroscopy (HR-LC-MS) analysis revealed presence of fifteen phenolic compounds namely chlorogenic acid, acetyl salicylic acid, dihydrorobinetin, dihydromyricetin, 2-isoprenylemodin, rutin, cosmosiin hexaacetate, pectolinarin, dihydroquercetin, eriodictyol, iriginol hexaacetate, theaflavin, Epicatechin pentaacetate, lomatin and peucenin in fruit extracts.
CONCLUSIONS:
This study recommends utilization of V. mullaha fruit as functional food with prospective pharmaceutical, nutraceuticals and cosmeceutical properties.
