Corrigendum to ''Role of hesperetin (a natural flavonoid) and its analogue on apoptosis in HT-29 human colon adenocarcinoma cell line - A comparative study'' (Food Chem. Toxicol. 50 (2012) 660-671)

On the basis of a scientific agreement, Dr. Roberta Bernini syn-thesized the hesperetin analogue tested in the present study andcompared it to naturally occurring hesperetin. Unfortunately, shewas inadvertently excluded as coauthor and now the authors wishto include Dr. Bernini’s name as follows:As a consequence:The sentence at the end of page 661, first column, section 2.Materials and methods; 2.1 Chemicals must be deleted‘‘Hesperetin analogue (HA) was obtained as a gift from RobertaBernini, Researcher in Organic Chemistry, University of Tusica,via S. Camillo De Lellis-01100, Viterbo’’. This sentence must bereplaced as follows:Hesperetin analogue (HA) was synthesized as described(Bernini et al. 2003). Briefly, hesperetin was firstly methylated bya classical procedure based on the use of methyl sulfate under ba-sic condition at room temperature to obtain methylated hesperetinin90%yieldafter 24 h.Finally, methylatedhesperetinwasadded toa suspension of methyltrioxorhenium supported on poly(4-vinyl-pyridine) 25% cross-linked with divinylbenzene (PVP-25%/MTO)in t-butanol and the mixture was warmed at 80 C.
