1. Cryptochlorogenic acid may be used as a reference standard in the determination of cryptochlorogenic acid in the leaves of Hibiscus sabdariffa using high performance liquid chromatography coupled with mass spectrometry (HPLC-MS).
2. 4-O-Caffeoylquinic acid has been used as a reference compound for the quantification in high performance liquid chromatography-diode array detector (HPLC-DAD).
Definition
ChEBI: A cinnamate ester obtained by formal condensation of the carboxy group of trans-caffeic acid with the 4-hydroxy group of (+)-quinic acid.
General Description
Cryptochlorogenic acid is a polyphenol, found in a variety of plants, which plays a crucial role in protection against various age-related diseases.
Biochem/physiol Actions
4-O-Caffeoylquinic acid (4-CQA) is a major active antioxidant marker in mulberry leaf extract. It is an inhibitor of ferroptosis hence, it is recognized as a potent anti-diabetic agent. 4-CQA plays an important role in the upregulation of nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathway.
Check Digit Verification of cas no
The CAS Registry Mumber 905-99-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,0 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 905-99:
(5*9)+(4*0)+(3*5)+(2*9)+(1*9)=87
87 % 10 = 7
So 905-99-7 is a valid CAS Registry Number.

Neuroprotective Caffeoylquinic Acid Derivatives from the Flowers of Chrysanthemum morifolium
Yang, Peng-Fei,Feng, Zi-Ming,Yang, Ya-Nan,Jiang, Jian-Shuang,Zhang, Pei-Cheng
, p. 1028 - 1033 (2017/05/05)
Three new caffeoylquinic acid derivatives, chrysanthemorimic acids A-C (1-3), and 11 known compounds (4-14) were isolated and characterized from the flowers of Chrysanthemum morifolium. Their structures were confirmed by spectroscopic data as well as by comparison of the experimental and calculated electronic circular dichroism spectra. Chrysanthemorimic acids A-C possess a rare 8-oxa-bicyclo[3.2.1]oct-3-en-2-one ring that is formed through a [5+2] cycloaddition of caffeoylquinic acid with a d-glucose derivative. Compounds 1-3, 6-8, 12, and 13 displayed significant effects against hydrogen peroxide-induced neurotoxicity in SH-SY5Y cells at 10 μM.
