Abstract
The mass spectrometric analysis of 3-deoxyanthocyanidins and anthocyan ins present in crude extracts from sorghum plant tissue was carried ou t by matrix-assisted laser desorption ionization mass spectrometry (MA LDI). Sensitivities to as low as 5 pmol/mu l were easily attained for pure samples of the anthocyanidin, pelargonidin, and the anthocyanin, malvin. Sensitivities to the level of 15 pmol/mu l were attained for 3 -deoxyanthocyanidins present in crude extracts from sorghum plant tiss ue. Through its capability for analyzing very small quantities of thes e compounds in unpurified samples, MALDI.provided a sensitive means fo r the detection of these flavonoid pigments in plant tissues.
