HPLC analyses of fruit, just after spraying with
extracts at the major concentrations and left to dry for about
30 min, showed the presence of very low amounts of residual
compounds ascribable to extracts. Whereas, the analyses per-
formed after storage on fruit treated with extracts at the major
concentrations and then washed, did not allow to detect any of the
main phenolic compounds resulting from extracts. Actually, taking
O. crenata extract as reference, 100 g of sweet cherry fresh tissue
(corresponding to about 8–10 berries) retained about 2 mg of
verbascoside (i.e., the main phenolic compound detected in this
extract) (Table 2), being such amount less than 0.5% of the average
content of 100 g of fresh edible tissue of broomrape, corresponding
to about 10 shoots (i.e., an average eaten portion) (Gatto et al.,
2011). Moreover, HPLC analyses performed on washed fruit
allowed to detect verbascoside below the instrumental limit of
quantification (LOQ) before storage, instead it resulted absent or
