Abstract

The development of a punch-card system for the retrieval of information on flavonoid compounds is presented. The system is two-fold, being useful for filing and retrieving literature data and for preliminary analysis of laboratory data. Direct or numerical coding of flavonoid structure, UV'analysis, and R_f values is discussed.
