Polyphenolic profile and antioxidant properties of rhizome of commercial banana cultivars grown in India

A potential of banana flower and pseudo‐stem as novel ingredients rich in phenolic compounds

“…In BBF EPP fraction (Table 4) and both HPP fractions (Table 5, Table 6), phenolic acids were the most relevant constituents, although some flavonol was also detected, which agrees with previous results in banana fruit and peel (Tsamo et al ., 2015). Previous studies also identified epicatechin and gallic acid in the banana flower associated with hemicellulose and in green banana flour (Bhaskar et al ., 2012; Pico et al ., 2019) or protocatechuic acid in the banana rhizome (Kandasamy & Aradhya, 2014). Nevertheless, for most detected phenolic compounds, identity could not be assigned, since they corresponded to structures not present in common databases nor literature on banana.…”

In vitro functional properties of crude extracts and isolated compounds from banana pseudostem and rhizome

“…But these extracts contain lower concentrations of terpenoids, alkaloids and steroids (Table ). The polyphenolic content of BPS and BR crude extracts showed that acetone extract had the highest total phenolic content (291 and 685 mg gallic acid equivalents g −1 of extract, respectively) and total flavonoid content (80 and 401 mg carbon equivalents g −1 of extract, respectively), followed by methanol, chloroform, ethyl acetate and hexane . Polyphenolic compounds such as gentisic, protocatechuic, caffeic, ferulic, chlorogenic and cinnamic acids, (+)‐catechin and catechol were identified from acetone and methanol extracts of BPS and BR by high‐performance liquid chromatography and electrospray ionization–mass spectrometric analysis …”

“…Very few reports have implicated sterylacylglucosides, naphthaleneacetic acid and methylisochroman derivative compounds as anti‐ulcerogenic, anti‐inflammatory and antihypertensive, respectively . We have also previously reported the antioxidant activity of polyphenols from pseudostem and rhizome of different banana cultivars and nutraceutical beverage from pseudostem and rhizome juice . Previous reports from our laboratory have established the isolation and characterization of chlorogenic acid, 4‐epicyclomusalenone and cycloeucalenol acetate and their antioxidant properties from banana rhizome) .…”

“…A very negligible proportion of this bio‐waste is used for consumption and for medicinal purposes. In indigenous ethno‐medical practices the rhizome is used to treat diabetes, haemorrhoids, intestinal worms, acidity, burns, wounds and pyorrhea . The pseudostem is used for urinary disorders, stomach troubles such as diarrhoea, dysentery and flatulence, removal of stones in the kidney, gallbladder and prostate, and is also used as an antidote for snake bite …”

Unveiling the Bioactive Potential of Fresh Fruit and Vegetable Waste in Human Health from a Consumer Perspective

“…The banana rhizome is very rich in phenolic compounds with important antioxidant activities [160]. The main phenolics found include ferulic, sinapic, salicylic, gallic, p-hydroxybenzoic, vanillic, syringic, gentisic, and p-coumaric acids, besides catechin, epicatechin, tannins, and anthocyanins [8].…”
