Sav. Alvarenga et al., Chemosystematic studies of natural compounds isolated from Asteraceae: characterization of tribes by principal component analysis, CHEM INTELL, 56(1), 2001, pp. 27-37
This work describes an application of principal component analysis (PCA) on
a database of secondary metabolites from the Asteraceae family. The number
s of occurrences of metabolites in 11 chemical classes for the different vi
bes of the family were used as variables, PCA allows the identification of
chemical classes that contribute most to the subgroups classification withi
n the family. Relationships between chemical composition and botanical clas
sification were made. (C) 2001 Elsevier Science B.V. All rights reserved.
