| Summary: | 碩士 === 東海大學 === 食品科學系 === 85 === ABSTRACT
Two major acylated anthocyanins of eggplant(Solanum melongena)
were isolated and was identified to be〝Nasunin〞
delphinidin-3-(p-coumaroyl-L-rhamnosyl-D- glucoside)-5-glucoside
and the other anthocyanin is the isomer of nasunin with cis
form coumaroyl. We also found that there is perhaps a isomerase
to interconvert them and worth more investigating in the future.
The purified anthocyanidins and anthocyanins were used to study
their separation in capillary zone electrophoresis(CZE) and
micellar electrokinetic capillary chromatography(MEKC)including
buffer system ,voltage and addition of organic modifier. The
results indicated that separation can be attained by addition of
organic modifier(methanol) and surftants(sodium dodecyl sulfate;
SDS) can improve their resolution.Capillary electrophoresis
showed good resolution、short separation time and small amounts
of sample needed.CZE and MEKC will be a new technique to
characterize anthocyanidins and anthocyanins.
