. However, the acylated anthocyanin (nasunin) was not detected in agreement with Wu and Prior (2005) and Todaro et al. (2009) but contradictory to Noda, Kneyuki, Igarashi, Mori, and Packer (2000), who reported it to be the major anthocyanin in eggplant.
This may be attributed to use of polar acidic solvents (in either extraction technique) causing partial to complete hydrolysis of the acylated anthocyanins and also to the particular variety investigated.
