Quince polyphenols preparations along with identification and quantification of their compounds using high-performance liquid chromatography with diode-array detection (HPLC–DAD) coupled on line to a mass spectrometer (MS) were performed as previously reported [13 (link), 15 (link)]. The thirteen identified pure compounds present in the quince peel polyphenolic extract (Peph) (Quercetin (Q), Rutin (R), (+)-Catechin (+C), (−)-Catechin (−C), Hyperin (H), Isoquercitrin (I), Chlorogenic acid (ChA), CryptoChlorogenic acid (CrA), NeoChlorogenic acid (NeA), p-coumaric acid (PcA), Kaempferol (K), Kaempferol-3-O-glucoside(K3g) and Kaempferol-3-O-rutinoside (K3r)) were purchased from Sigma (Sigma, Aldrich).
Kaempferol 3 o glucoside k3g
Manufactured by Merck Group
Kaempferol-3-O-glucoside (K3g) is a flavonoid compound that can be used as a reference standard in analytical and research applications. It is a naturally occurring glycoside found in various plant species. K3g is commonly used in the identification and quantification of this compound in samples through analytical techniques such as HPLC and LC-MS.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
