Anthocyanins
23
Flavanoid phenolic compounds based on an oxonium ion ring structure (commonly
24
pelargonidin, cyanidin, delphinidin, peonidin, petunidin, and malvidin), with one of the
25
following substitutions at the 3, 5, or 7 site: simple sugars such as glucoside, arabinoside, or
26
galactoside; oligosaccharides such as rutinoside, sambubioside, etc.; or acylation on sugar
27
with coumaric acid, acetic acid, etc.

Identification
33
Identification is the characterization of the substance being analyzed, including its chemical, mineral,
34
or biological classification, as applicable. In many investigations the identity of the analyte is assumed
35
and the correctness of the assumption is merely confirmed.
