Banana passion fruit (Passiflora tripartite L.H. Bailey) is a lesser known species of the
genus Passiflora. This fruit typically grows in the Andean region of Ecuador and it is locally
known as tumbo, taxo or curuba. The juice of this fruit is highly appreciated in South America.
Extracts of banana passion fruit were characterized for their content levels of free and bound
phenolic compounds by high performance liquid chromatography coupled to high resolution mass
spectrometry detector (HPLC-ESI-TOF-MS). A total of 82 polar compounds classified as phenolic
acid derivatives, organic acids, benzophenones, flavan-3-ols, flavonols and flavones were detected in
the extracts. The total phenolic content was 2356 mg 100 g−1 dry matter, with the bound phenolic
fraction representing 37.7% of total amounts. Flavan-3-ols, such as (epi)catechin, (epi)azfelechin
and their derivatives, were the main phenolic compounds in the free phenolic fraction; however,
phenolic acids represented the most abundant class of bound phenolic extracts. The antioxidant and
hypoglycemic capacities reported for banana passion fruit were higher than for other fruits. To our
knowledge, this is the first time that bound phenolic compounds have been described in banana
passion fruit pulp.
