摘要:
Anthocyanins found in some plants of the Commelinaceae family have shown to be very stable compared to other commercially available natural pigments. One source of these stable anthocyanins is found in the plant Tradescantia pallida. Through the use of chemical hydrolysis, mass spectrometry, and H-1 NMR, the major anthocyanin from T. pallida was characterized to be 3-O-[6-O-[2,5-di-O-(E)-alpha-L-arabinofuranosyl]-beta-D-glucopyranosyl]-7,3'-di-O-[6-O-(E)-ferulyl-beta-D-glucopyranosyl]cyanidin.
